Hi all, I've just built a new system and it included a Corsair RM650x PSU. I am aware that the fan will be off when not under load and under a certain temperature threshold. But what i didnt expect is that it would constantly ramp up/down over and over again. It's doing it to the extent where I'm questioning wether its working Ok or not.. So currently, my CPU Core temps are at 38-41*c average across all cores. My GPU is at 56*c. Case ambient (as reported by the motherbaord, so take that as you will) is 32*c. Room ambient is very cool, as its the time of year in the UK to have all the windows open for airflow, lol.. Its actually fairly chilliy in this room. So I have no reason to believe that the PSU is over whatever threshold it might have to trigger the fan to come on (what is it?). Also, the system is under almost no load. I'm literally just running RealTemp, OpenHardwareMonitor, and Firefox to write this post, lol. So why is it that the PSU's fan will ramp up, from silent to very very audible for aroun 5-10 seconds, then ramp down to silent again, and remain silent for around 5 seconds, then ramp the fan up again. Over and over again, and I'm not exaggerating with those timings, whilst writing this post its ramped up/down maybe 20-30times. The exhaustted air at the back of the case doesnt "feel" hot at all, it just seems like its pointlessly spinnign the fan up and down at very close intervals. Anyone have any experience with this? Is it normal? It doesnt seem it to me. I may try to return this to the supplier as faulty, can anyone recommend a PSU that has more active management of its fan? Or perhaps I should just get a corsair with manual software fan control... Dave.

I had not considered Ryzen until this point. I have been building systems since I was 16 (I'm now 28), I'm jsut very out of the loop of the last ~2 years of developments. I hahve never used an AMD CPU, not once, in all the yers it's been Intel every time. Because of that, I am naturally biased towards Intel, lol. Thankyou for the note about GPU and RAM. GPU I actually agree with you on. RAM not so much, I'm finding my RAM not to be a real limitation at current, and 16Gb is an upgrade from what I have. Wow, thankyou for this. I appreciate the time spent on speccing the builds above. I looked at a lof of benchmarks between things like R7 1700's and i7-7700's, and it did seem like that Intel edged in front of the Ryzen, especially around gaming and single threaded work loads. It makes me second guess the Ryzen responses in this thread, as I will be gaming, and the differences were quite stark. The change up to a 1070 is agreed, I will take that on board and ensure I'm running that rather than the 1060 I had specced. The removal of the SSD is fine, it was more of a luxury item, but in reality, my boot drives are plenty fast for now. The removal of the Corsair AIO cooler, hmmm, well, i did plan on overclocking the 7600k when I had that specced, so thats why I had that cooler there. If I can, I will want to overclock the Ryzen too. My current CPU (i5-3570k) I have long term stable at 4.4Ghz. If you have any points to make regarding the benchmarks mentioned above I'd really like to discuss those. Thankyou for the vouch of confidence for the Ryzen builds. Are you able to shed any light on the benchmarks i mentioned above? Essentially an i7 7700 beating the Ryzen7 1700 in games and single threaded workloads? Thanks all.

I am not using the 850 EVO. The item I posted is the 960 EVO. Good information there, many thanks for the detailed reply. This is the first time I've lookeda t M.2 drives as an option, and they are attractive to me for a number of reasons. Based on your info, and what I've read since, I can see clearly that the parts would work together, however, I had a change of direction, and have now leaned toward a z270 board. Again, the parts will work together from waht I've read. So thankyou again for your help. Appreciated. Dave.

1. Budget & Location Location: UK Budget: Semi-flexible, £900-1100 GBP target. 2. Aim Mostly, it's a triple monitor work machine. I work in IT and work from home a lot, its a produtivity machine involving coding, network and traffic analysis etc.. Along with fairly heavy use document and diagram creation. I use Photoshop casually. There is also a requirement for casual to medium gaming, but only at 1080p, as my 3x identical monitors are 1920x1080 native. I'm fine with NOT making the switch to 1440 etc.. 1080p gaming is just fine. 3. Monitors 3x 24" 1080p monitors currently running off of DVI. I expect to have to convert these from display port on a modern graphics card, thats fine. 4. Peripherals No, I have all the peripherals I need. They are not included in this build. 5. Why are you upgrading? My current rig has run its course. more and more I'm finding the slow downs being noticeable. in gaming, I struggle to play the things I want to at very nice settings these days. Overall it's just showing its age. My current rig is 3.5 ish years old: i5-3570k nVidia GTX 670 8Gb Corsair Dominator (DDR3) I have a collection of SSD's in RAId arrays also, that i'll be re-jiggling into the new machine. 2x Intel 530's in RADI1 (boot device). 4x OCZ Agility's in RAID10 (used as a production file system, faster access, redundancy). I also have a 4Tb internal SATA drive, and a few external 2Tb backups drives, so storage isn't to be concerned in this build. I will handle that. My propsed build so far: Intel i5-7600k ASUS Prime Z270-K Motherboard eVGA nVidia GeForce GTX 1060 6Gb SSC ACX 16Gb (2x8) Corsair Vengeance LPX C14 DDR4-2400 Samsung 960 EVO 250Gb M.2 SSD Corsair RM650x PSU NZXT S340 Elite Black Case Corsair Hydro Series H115i 280mm Liquid Cooler TOTAL PRICE - £1136 GBP The main areas where my knowledge limitations held me abck on making confident decisions were the Graphics Card and RAM. But I'm open to consider and research suggestions and alterations made on other parts.

Hello, I would like to use this M.2 drive: http://www.ebuyer.com/766047-samsung-250gb-960-evo-m-2-ssd-mz-v6e250bw (Samsung 250GB 960 Evo M.2 SSD) Which runs in PCIe 3.0 x4 NVM Express mode. The board I'm using is: http://www.ebuyer.com/769574-asus-intel-prime-b250-pro-lga-1151-atx-motherboard-prime-b250-pro (Asus Intel PRIME B250-PRO LGA 1151) Which states that it has an M.2 slot, and that it operates in SATA or PCIe mode, and then says it supports Intel RST or PCIE x4 mode. That all sounds good, but it doesnt seem to mentione NVMe anywhere.. A direct quote from the baord summary: - 1 x M.2_1 Socket 3 with M Key, type 2242/2260/2280 storage devices support(both SATA & PCIE x2 mode)* - 1 x M.2_2 Socket 3 with M Key, type 2242/2260/2280 storage devices support(Intel RST support, PCIEX4 mode)** *(1) When an M.2 device in PCIE mode is installed, PCIE x16_2 slot only runs @ x1 mode and SATA6G_1 port is enabled. **(2) When an M.2 device in SATA mode is installed, the M.2 device uses the SATA6G_1 bandwidth. SATA6G_1 port is disabled. Could anyone shed some light on whether NVMe even matters in this case? Does the fact that the board supports PCI3.0 x4 mode on its M.2 slot mean that it will just work regardless? Also, if it does work, I will want to use it as my boot drive, will that be ok? As I have heard some things about booting from NVMe addin cards before, not sure if M.2 slots are similarly affected? Thanks all! Dave.

Just ran Prime95 at 4.6Ghz @ 1.35v. Core 2 and 3 hit 105*c which means the CPU will throttle regardless of BIOS settings and motherboard controls etc.. So yeh, there you go. don't sue speedfan, lol. It was over 30*c innacurate.... Looks like I just justified my watercooling order that I was umm'ing and aah'ing about for the last few weeks Woo! Thanks all, Dave.

Thanks for the recommendations, I'll get both of those and have a cross-reference with speedfan. thanks Ah thankyou, apprecaite the link. Downloaded, will run through the readme and give that a test. However I think I agree with you and others who ahve said thermal throttling, I setup a 4.3Ghz OC and bench'd that with prime95. It was 100% stable, and stuck at 4.3Gh, until speedfan reported 73*c ish. At which point it started pulling back the multiplier. I imagine the real temp was much higher than 73. At 4.3Ghz it took a lot longer for it to get to 73*, and the whole time it was below it, it functioned fine with no multiplier problems. I will carry on and see how it goes. Thanks for the advice. Dave

Hi, I've just updated BIOS to 2.90 (the latest one) and I'm still seeing the same unfortunately. Hi, I couldnt find ThrottleStop 8 anywhere, so I downloaded 6.00. I couldnt find any "limit reasons" program or secton of it though. Doy uo have a link to 8? Interestingly it did report all 4 corsa at over 90*c though... Could this be extreme thermal limiting but SpeedFan is jsut reporting the aggregated CPU temps wrongly? I have clocked at more "reserved" multipliers but I still see the same sorts of behaviour (albeit after a much longer period of time ont he lower overclocks.)

It's strange, I've just finished pricing up a watercooling build too... AMybe this is the push in that direction that I needed haha

Hi, I thought that to, so looked up throttle temps for the 3570k. There didnt seem to be one, apart from the hard throttle limit of 105*c thats embedded into the chip from intel. My cooler is a 2nd revision Arctic Cooling Freezer 7 Pro. t's not an insane cooler, but it does pretty well I think. 70-73*c I didnt think was that high for an i5? I could be wrong, I'm a bit out of the loop these days, lol.

Hi all, Wondering if anyone can give me a little insight into whats going on with my overclock. I built this system a little while back, played with overclocking at the time but didnt have much luck .I now understand it a bit more and thought as I've got nothing else on toady, I'd give it a go. I'm getting some interesting occurences though, let me explain: System Specs: MOB - ASRock Z77 Extreme4 CPU - i5-3570k RAM - 8Gb Corsair Vengeance DDR3-1600 SSD - 4x 120Gb OCZ Agility 3's in RAID10 GPU - nVidia GTX670 PSU - Coolermaster SilentPro M600 (600w Modular) Overclock: Multipler - 48 BaseClock - 100Mhz vCore Type - Fixed vCore - 1.350v Resultant OC - 4.8Ghz Problem: With the vCore set to fixed, and not offset, the clock speed in windows at idle will be 4.8Ghz, the vCore does not fluctuate, the mlutiplier does not fluctuate. Temps at idle are around 40-45*c. Under load (4 workers in Prime95), the temperature will increase to around 70-72*c, but at this point, I notice that the multipler has been pulled all the way down to (sometimes) 23.... Resulting ina clock speed of 2.3Ghz. The vCore remains the same at 1.350v or very close (sometimes dips to ~1.344v. I ahve gone through every setting I can think of to stop this from happening, I was originally using offset based vCore, and in this case, the vCore was dropping a lot more than it is now. But its still happening to a lesser extent on fixed vCore. it's 100% stabel, but then it would be because its only running at 2.2-2.8Ghz under full consistent load. It's worth noting that before it pulls the multiplier, it runs under load for around 5-10minutes at 4.8Ghz perfectly fine also. Any ideas on how to avoid the mulipler dropping? I dont really want the BIOS or Intel or anything changing it whatsoever. I'm not worried about power consumption or electricity bills, I just want the vCore to stay the same. Thanks, Dave
