Pc cannot reboot properly I have a pc with an MSI z87 g43 motherboard and recently got an i7 4790k to use with it. I updated the bios to version 1.8 and it works but the pc is unable to reboot properly. If i try to reboot it, it turns back on and the fans spin but the usb peripherals and monitors receive no signal. I always have to turn the pc completely off and back on again and this is making it difficult to install windows on the pc.

Budget (including currency): $300-500 Country: US Games, programs or workloads that it will be used for: Gaming Other details I currently have a i7 4790k, 16gb DDR3 ram, and a gtx 1650. My motherboard is a asus H81I-PLUS but it’s basically trash. I’m looking to increase performance hopefully just by upgrading my motherboard and maybe my ram.. I can play all games well and can even get a steady 30fps on high graphics on Cyberpunk 2077.

Hi! With Cyberpunkt 2077 releasing in a few days I thought it would be a good idea to get every last bit of power out of my 4790k. The problem I have is that my i7 4790k doesn't want to go to any clock higher than 4.4Ghz. I have an MSI H97 Gaming 3 as motherboard (yes it is an H chipset, yes it could OC). I already overclocked the same CPU on the same board a few years ago just to see how far it could go and I could at least OC it to 4.7Ghz. That OC was stable and also did apply properly. I don't know what changed in the meantime but now I want to OC it again since now I really need the OC and it just doesn't want to boost to the set multiplier anymore as if it is capped at 4.4Ghz. If I reboot into BIOS and check the multiplier again, it is still set at the OC I entered and every tool in Windows also reports that same maximum multipier. I already tried to restore BIOS defaults, reset CMOS, various combinations of OC settings. I would appreciate every help on how I can get the CPU to go over a multiplier of 44 again Thank you for every input and please let me know if you need any further information to be able to help me! Edit: I knew someone would say I need a Z chipset board, but no, some H97 board actually could OC a K CPU including the MSI H97 Gaming 3.

So today I treated myself with a used RX6600XT that performed on par and even better than what to expect from it in 3DMark Time Spy. It was tested in the sellers system, the guy put the GPU into the system with brand new driver install so no problem there. I bring it home, put it into my system consisting of: i7 4790k @ 4.8Ghz 32GB 1600MT/s Asus Maximus VII Hero Asus Dual RX6600XT 8GB Before this GPU upgrade I had a RX580 4GB, games ran fine but anything more demanding, set it back, especially because of the 4GB VRAM. After DDU‘ing drivers and installing the latest from AMD, I fire up PUBG, a game that I mostly play, on the old GPU it ran at about 100FPS at 1080p. GPU sat usually at 100% while CPU was chilling at 50-60%. On the new one it runs at 80-90FPS while GPU and CPU sit at 40-50%. I know 1080p is CPU intensive but I should at least be seeing an improvement over the old one, not worse. I also fired up BeamNG.drive where I saw a similar situation. Low GPU and CPU usage as well as low FPS (compared to old one). Old one ran it 70-80FPS, new one runs it at 60ish. For the record, my monitor is 75Hz which is the threshold I‘m looking to achieve. So at this point, I don‘t know what to do. I currently don‘t have money to upgrade to a new platform but that is in the works. I just want to play games at more than 75FPS and it‘s mind boggling to me how an upgrade can actually take you a step back. If anybody knows the sollution, I‘ve already looked at a few other topics regarding similar issues with the same GPU but I can‘t find any correspondence with mine. Any help is appriciated.

Good morning, I have had the same i7 4790k since 2017 and just recently upgraded my GPU from an R9 380 to a 2070 super. I did achieve some performance improvement obviously but maybe not as much as I would like. For example: Warzone on Ultra @ 1080p I am achieving 80-110 fps and sometimes it drops into the low 70's. I was wondering if the CPU is holding me back since it is quite old and if so what would be some good suggestions on upgrades? My Build

Hey, Havent been active on here for a while but I recently upgraded to an i7 4790k in a good deal, in overclocking I have it stable at 4.6GHz and 1.3v, I can push it up to 4.7GHz at 1.4v and 4.8 at 1.55v. This seems rather high to me, and 1.4v is the upper limit of my cooling, despite a custom water loop (rather bad CPU block which needs upgrading, I also have suspicions that the IHS needs lapping). Are there any tips for overclocking the 4790k that I might be missing? Because the voltages seem rather high for the respective clock speeds.

Hello, I am very new here and I've got a burning question to ask. The question in mind being "Should I buy a used CPU with a faulty memory controller?". I have had plenty of experiences buying used hardware but I have yet to buy something which has a bad memory controller. How would a faulty memory controller affect everyday tasks, which should be my main concerns, is there anything I could do to prevent typical behaviour caused by this problem,how safe is it to actually use this CPU for somewhere in the ball park from a year to two at most. I have found this CPU on my local ebay sort of site, buy and sell used products, where I have previously bought items which have worked completely fine with no issues. The CPU in question is the 4790k, it comes with an ASUS maximus ranger vi, 16gb vengeance pro and a hyper 212 evo all for around 350usd (that's around 465cad since I see you're a Canadian site). It is clearly stated that it has a memory controller issue and that it doesn't recognize 2 ram slots, should I be really worried and stay away from it or is it fine to use with just the remaining 2 ram slots? Thanks in advance (sorry for bad englando)

So I have cleaned up my PC from dust and all that stuff, then when testing thermals I also tried to play around a little with clocks just out of curiosity - and to my surprise i am at a much higher clockspeed on my 4790k than i reached some time ago when I tried last time. It actually runs stable at 4.85GHz now (with 4.8 cpu clock and 101.00 base clock), compared to the 4.7 form before - and tho I also pushed Vcore up to 1.395 the temps didn't really go up that much - 79°C Tmax on the hottest core. I have tried even 1.4V before to reach 4.8 ghz but it didn't work out - so I am prety surprised it did this time. Also cinebench scores went up pretty nicely - 975 Multithreaded, 190 single core. (up form 922 / 185) So what I am trying to figure out here is if there is a possibility that a CPU might overclock better over time or if I just messed something up last time. And I also wanted to just report how awesome this is. ^.^

hi all im new here and i need know what is the max voltage cache for my i7 4790k cpu? because i have this at 4.6ghz OC with 45x cache ratio multiplier at 1.29v and i found stability but i have read that cache voltage should not go beyond that 1.15v (strange, but by default this is at 1.185v 40x cache ratio) and i have mine at 1.29v. that for im worried. my motherboard is an z97a.

Hi Guys, First time posting here :-) I know short and simple may work but I want to give you some back story. I am using my PC for music production and gaming. After a while away from audio production (too much gaming) I decided to try my software (pro tools) it did not start and was having issues. No big issue I thought - WRONG. Tried reinstalling..nothing same issues. A few hours later and still no change. EDIT this issue came about after moving all installer files (.msi etc) I DID MAKE BACK UP ETC ( i just heard moving them would free up the space on my SSD ( DONT DO IT) So after scrabbling around for ages I thought sod it and made a backup image of the drive and did a reinstall of windows. After finishing this I installed pro tools and boom it worked. So I assumed it must have been the installer files. So I made a image of this system and restored the old one ( this is due to the other software I use and not wishing to have to install all of it again) So now I have recovered the older image, replaced installer files with new ones from new system image I also then replaced them with the back up of the installer files I had already made previous. loaded pro tools and plugins again just in case and boom it worked amazing..... Now the issue, after checking pro tools works, I wanted to check my gaming situation and nope I have issues. I fire a gun in the division and i get delay massively. This I did not get as before, the games where not an issue and running like a dream. I have ran Sfc scannow (or whatever it is in cmd) I have ran Cinebench (slow as hell) I have ran AVG Auto tune up to stop background programs etc etc. now also just done "manage 3d settings" in nvida control panel to restore. oh i also checked game files and all there was, was and update for the division and it downloaded directx again.

im going to upgrade my PC, well im upgradeing my cooling, GPU and case mainly, but i need some help picking those. budget is going to be around $800-$900 for the entire thing but in that budget there may have to be an RX 470/RX 570 too thats going to be around $170 and will be used for the Toaster Project, so i would like two options if you can bother, one for around $750 and one closer to the $900 mark if needed. my aim? badassness, 1440p Black Desert Online on max settings and watercooling.

Someone please tell me how the fuck so many people reach so high clock speeds with so low voltage because my i7 4790k cant even run 4.5ghz stable at fucking 1.300 volts cmonBruh

it all started about two days before i got my I7, i was playing Paladins and i got a BSOD(Paladins was the only thing that could take it down lol) and then i booted back into the computer, it seemed fine but after just a bit it froze up, mouse still working, keyboard still working. i could move around the UI, drag stuff around and all that but all programs were compleatly frozen and unresponsive, i could open programs but not close them, not even using taskmanager. i turned it off and held the powerbutton for a while and then booted with no problems. i got the probem again the next day when strating a game it would after just a little bit just freeze up in the same way. i got my I7 4790K and installed it, on first boot it hanged on loading the BIOS so i turned it off again, flipped the PSU switch and pressed the powerbutton for a bit and then started it up again and it booted just fine. when i went to do some overclocking on it i noticed after a bit that it was crashing because my memory timings were out of wack, they had all gone down by one, makeing it boot but not pass any load. so i fixed that, pressed F10, and it hung on loading the BIOS again. same procedure again, and it booted fine with the changed memory settings and so on. i put the CPU back to stock later because of heat but when i pressed F10, again, it hung on the BIOS again. anyway i got it into windows again, everything was working fine today and i was playing some OSU, i go to tab out to another window and BAM the freeze hits again. it did this for sevral more games and all it seems to be able to do no problem is web browsing i have put back everything to stock, reinstalled GPU drivers clean with DDU and that didnt help either but now here comes the real kicker, i updated the BIOS to the latest version and now it dosent boot at all past the BIOS, a message that says: "loading GRUB please wait 5 seconds" comes up and then it reboots and it keeps going. i can get into the BIOS but its refusing to go past loading the BIOS and wont reach windows.... so someone tell me what to do here, im thinking il need a new motherboard tbh, this one has a few small scratches but nothing that is shorting any traces, it got compleatly cleaned when i put in the new CPU and the problem was there before the new CPU even so its not the CPU or RAM. GPU shouldent cause issues like this either so its not that which leaves two things, motherboard and harddrives. the harddrives are as far as i know in good helth(checked about a week back in crystaldisk info) so it all points to the motherboard at this point, but if you have any other clue what it might be id love to hear, il test basically anything seeing as it can barely get any worse unless it goes up in litteral famles

Hi, My comp has this [specification] (https://pcpartpicker.com/user/dharanikanth.s/saved/ZfkqsY) with custom watercooling installed. I recently bought two more 4gb Corsair vengeance 1600mhz sticks for the comp. But when I try to use all four sticks or RAM, the mobo doesnt post and hangs up at CPU PEI initialization based on debug code on the mobo. I also tried timing the CPU down to the speed it defaults to (1333mhz) and still same issue. It works like 1/10 times where it boots into windows but when I put the comp to sleep and try to power up, the boot fails on me. Anyone encountered this issue before? My CPU is OC'd to 4.6ghz at 1.225v. OC passes AIDA 64 stress test with a max temp of 75C. So OC is stable. I'm just wondering why I'm getting this error while booting with all four sticks. I have tested all the slots and it works fine when I tested both sets of ram individually on every slot by itself. I only get this error when using three or four sticks of RAM. Please help. Thanks, Scarfoot

What's better for hard core gaming i7 6700k or i7 4790k I'm also having 16 gb of ram and a gtx 1070 FTW

Current specs- corsair cx 600M, i5 4690k, Strix 1070, 16 gigs of ripjaws gddr 3, and a 1 TB HDD. Soon I will be moving to a place with fiber optic internet. I am really wanting to stream system intensive games like arma 3. I am looking at the i7 4790k. But I know almost nothing about cpu's. How much of an upgrade would this be? Would I see better fps in games like arma 3 that are very cpu intensive. And would I be able to stream comfortably. Also as a side note. Should I get a better psu first? ive had everything from the corsiar cx 600M is awful and will damage my parts to that it is completely fine. I am not wanting to change socket type so keep that in mind thanks!

Hi, i have a i7 4790k and a Asus Maximus Vii Hero... my questioin is can i use this m.2 ssd on my system ? Because someone asked me if i have nvme and i am not quit sure about it. I couldn t finde anything.

I see a lot of conflicting information on this question. EIST and c-states. Should you enable or disable them for an overclock? i just stress tested both at 4.7ghz 1.245v on an i7 4790k and I noticed my max temps were 2-4 degrees hotter with c-states disabled. That’s about it. here are the various things I’ve gathered about this: some people say that the jump from a low voltage to your set core voltage while starting a stability test or vice versa can cause a misleading blue screen so to turn them off while stress testing. some say that if it makes it blue screen then, they’re uncomfortable having it on at all. some say it doesn’t effect your overclock at full load anyways. some people say it cause an increase in latency. That’s just tip of the iceberg too. Is any of this right because it seems like there’s no consensus?

Hi, everyone. I have a question. On cinebench r15, when I run the full cpu multithread test, my temps are high, as shown below in the picture. Are they too high? I have re applied an Arctic Silver 5, and am using the Stock Intel cooler (for 6th gen tho). I am planning to buy a delidding tool, some coollaboratory liquid ultra, and delid my cpu and then overclock it. Will there be any difference in temps, after delidding? Also, I forgot to mention, my ambient temps are 28C. Thank you for your time.

I've been getting FPS stutters for the longest of times, it happens when i play games like PUBG and even optimised games like league of legends (rarely) i tend to get around 90fps on pubg then i spike down to around 60 and get a huge 1 second freeze. This is really annoying when playing games and it happens quiet frequently (10 times a minute) im using a Gigabyte Windforce edition GTX 970 (no overclock) and an i7-4790k (no overclock) my thermal paste was renewed 1 month ago (stock cooler) and i get 99c on load on my cpu and 40 on idle, my friend gets 40 on idle but 80 on load with the exact same processor and stock intel cooler. In MSI afterburner my GPU usage spikes from 100 to 70 and the spikes are synced with the FPS drops/stutters. any help?

Hi guys, I have recently started experiencing massive performance problems on my gaming PC. Here are my specs, before I get into the details of the problem: i7 4790k CPU MSI z97 Gaming 7 motherboard MSI GTX1080ti graphics 16 GIG of Ram at 2400mhz 850 Watt power supply Windows 10 running off an SSD So, it started with game performance dropping dramatically while playing games such as Witcher 3 and Dragon Age Inquisition. I would normally get a very solid frame rate of 60FPS on both these games at 1080p, but lately it would suddenly drop to as low as 10FPS! So I started investigating... Long story short, there is absolutely nothing wrong with my graphics card. Benchmark scores on 3DMark using the Extreme tests still shows average of close to 60FPS and with a stability rate of 98%. However, using CPU-Z to benchmark my CPU resulted in very alarming results! The reference 4790K would have a single thread score of 444, while mine comes in at 86. The multi-thread score for the reference is 2282, mine is a pathetic 427!!! My conclusion from this is that there is definitely a big problem somewhere, but I am not sure if the CPU is failing or if the power supply is failing or maybe the motherboard? I'm getting no beeps, no PC crashes, no signs whatsoever suggesting a hardware failure. As part of my attempts to solve the problem, I have done things like completely formatting my drives, re-installing Windows, flashing my motherboard BIOS with the latest version from MSI, unplugged all power cables and re-did them, tried switching to the alternate BIOS on the motherboard, flashed that as well, switched back to the initial BIOS, but nothing seems to help! My next step would be to replace the power supply with a new one, but I would appreciate some insight into what else I should try? Any help would be much appreciated!

So after I made a thread about OBS basically halving my FPS when I start streaming, I realized another problem that I have that I'll also need someone with similar specs to confirm to me. First off, I'm running a Gigabyte G1 Gaming GTX 970, i7 4790k at 4.7ghz, 12GB of RAM at 1600mhz and I've got Overwatch on my SSD. Basically whenever I'm in the main menu of Overwatch, the practice range or in a bot game that I've made, the GPU load hovers from 90 to 99%, which is ideally what I want. My fps barely drops below 200 in 5v6 bot fights that I spectate from somewhere on the map, and when they're done, the FPS goes back up to 250-290. Whenever I jump into a multiplayer game though, be it quickplay or a competitive game, the GPU load does not want to go above 55%. It sometimes reaches 60%, but it quickly goes down. My FPS is therefore hindered by that and I'm forced to play at FPS that drops down to 150 and even below 110 whenever I'm watching a killcam of someone. I am not sure if this is normal FPS for my setup, but I play on 75% resolution scaling and everything on low, except for shadows that are on medium and texture filtering that I've put to 16x because I didn't see any performance change whatsoever. This is all a problem to me because I play on a 144hz monitor and whenever I try to stream the game, OBS halves my framerate on top of it already being low. GPU drivers are up to date, Windows is up to date, I just have no clue if this is normal or not and I'll be greatful if anyone has a fix for it.

So basically i like to play around with the Paladins game files, but all i have done this patch is to raise my framecap to 250fps rather then 150. im playing at 1440p maxed out settings 2xmsaa and im not getting 100fps a lot of the time, GPU usage is at ~45% and the same for the oddly 5 threads it uses. It dosent seem to be the RAM either. So it has a LOT of resources to play with, but the FPS is nowhere close to what it should be. if anyone has any clue as to whats going on here that would be great because im out of ideas. specs: GTX 1080 running 2088MHz I7 4790K @ stock 16GB of DDR3 1866MHz full specs in Northern Bee buildlog, everything is watercooled and temps are extremely fine with 33C on the GPU and around 50C CPU Thanks for any help

What's up guys, As the title suggests I need some advice! (Hope I'm in the right forum) Current Specs: CPU: i7 4790k 4.6ghz 1.3v ( I know, terrible chip) also delidded with coolaboratory liquid ultra. Cooler: NZXT Kraken x61 TIM here is also LM Mobo: MSI z97-g45 Gaming Ram: 16gb HyperX Savage 1866mhz PSU: Corsair RM750 GPU: 2X GTX 1080 Strix SSD: 250gb Samsung 850 evo HDD: 4TB Barracuda Case: Phanteks Enthoo Evolv ATX TG Monitor: Asus ROG Swift PG348Q Planned Specs: CPU: i7 8700k (Will definitely delid) Cooler: EKWB Supremacy Evo (already have that) Mobo: Asus Strix z370-F (already have that) Ram: 16gb G.Skill Trident Z RGB 3200mhz CL16 (already have that) PSU: Corsair RM1000i (already have that) GPU: 2X GTX 1080 Strix with EKWB Blocks (already have the blocks) SSD: 250gb Samsung 850 evo HDD: 4TB Barracuda Case: Phanteks Enthoo Evolv ATX TG Rads: 360mm top // 280mm front Monitor: Asus ROG Swift PG348Q I neither want to use a monoblock or watercool the ram, just to be clear. Now on to my questions: 1. Would you guys use LM TIM between the Supremacy Evo and the IHS? I've done this with my 4790k and it worked great; load temps never exceeded 65°C 2. Do you think the 750W PSU was enough? I've read that the strix cards themselves have a 300W+ TDP. But I have yet to run into stability issues. 3. Are the two Strix Cards enough for Ultra settings in current titles, after all the monitor is 100hz and 1440p 21:9 is a lot of pixels. ( I don't know if I should uprade to 1080TI's or not) 4. Would you use LM TIM on the GPU Blocks? I have done one already, but I have yet to test its function. I don't want to fry the gpu after all. 5. I've seen alot of people do the shunt mod on their Pascal Cards, and I'm interested. My cards don't overclock too well (on air at least) and having the extra horsepower would surely come in handy. Any advice here? Maybe someone has already done this on a Strix card. (I don't necessarily wan't to use LM as I've read threads where the Shunt Resistors would fall off after some time due to the Gallium Corroding the solder) And lastly, what do you think of my build? Will love to hear your opinions and advice Greetings from Germany! Pascal

I noticed my 4.7 overclock is peaking at 4.804 in the aida64 stress test. turbo boost, EIST, and c-states are enabled, it’s on dynamic, the core clock settings are all on auto, the vring ratio is 4.4, and cpu voltage is on override at 1.23v. cpu core clock peaks at 100.10, my cpu core voltage goes from 1.23 to 1.256. if you do the math here: 100.10 x 47 x (1.256/1.23) = 4.804 is this supposed to be happening? I didn’t think turbo mode put you over when you have a manual clock speed. I7 4790k msi z97.pc mate
