I need a replacement battery for this https://www.ultrabookbatteries.com/genuine-asus-x540l-a31n1519-a31lo4q-33whr-10-8v-2-9ah-battery.html/A31LO4Q and was wondering if anyone knew of any cheaper options or a better replacement for it. Looking at the battery it looks pretty simple, could I simply buy 3 new NCR18650A batteries (the one i need a replacement for comprises of 3 of these taped together with a red and black wire connecting) and redo the connections myself? Or even buy 3 better batteries to replace it with a better one? How would I go about this; how difficult/dangerous would that be?

I built a home server months ago to use for various stuff. The problem was the form factor of the motherboard. It could only align on two standoffs in one corner. I had it in a HAF932 with its back panel off and on its side and with HDDs taped to the case. Not exactly Ideal or pretty. I recently sold my gaming PC, besides its C70 case. I went on a mission to add custom standoff locations to the C70 to support the special EE-ATX board I had. This is what it looked like before Before I go into details, the finished build and setup(specs in my signature): First step was drilling out the old standoffs on the case. The C70 had built-in standoffs so they had to be removed. I did this by simply drilling into the sheet metal from the backside. Next I confirmed the CADD drawing I had made and was using as a template was right. (perfect fit) I then had a method for adding in support posts. I would use a screw with a plastic tube cut to size, along with washers to help spread weight around the holes and a nut to secure it. Not the best, but it looks fine and worked great. I found single pieces of the plastic tubes the board would sit on to be too short, so I taped them together with red tape and sanded them down to the correct height (pictured later) I then placed the screw assembly, and hot glued them to secure. I added 5 standoffs and two standoffs could be left from the original layout. Next I laid out the board, and secured it with the washers. The board was held firmly in place and my main concern, the weight of the CPU heat sinks at the top, was gone. Next I built the PC, it looks suprisingly good cable management wise considering the ONLY cable management port I was left with was on the bottom as the EE-ATX board is quite large and over-extends over E-ATX and it was a non-modular PSU. I now have a desktop PC with 16 cores, 32 threads, 72GB of RAM, a GTX770, and 3 monitors worth of work space. Using my laptop a lot, my server now doubles as a awesome and powerful work space for stuff like CADD and high-end gaming and with plenty of storage for files. With some older NVIDIA drivers and the addition of a sound-card, and some settings changes, I can even run games and audio even though i'm on a server motherboard and Windows Server 2016.

I tried delidding 2 CPUs today. Same issue both times, the TIM around the edges came off easy, while it was like concrete on the actual CPU, causing the actual CPUs to rip off with the heat spreader. The Q6600 kinda ripped in half, with silicon particles falling out and pretty severe damage to the CPU, but it made for cool microscope pictures. Any suggestions of how to not have this problem happen? I still have an old Xeon laying around, although it has a lot of modules on top of the PCB I will have to work around. http://imgur.com/a/Tf8G1 is there any way of posting an imgur album link here? EDIT: someone mentioned it could have been because it was Soldered on, which I have heard about but didnt even consider. Is this the case?

Im looking for a <$150 PC made using only used hardware (purely for cost saving) that will be meant to be use as a router because im so done with my Netgear router's horrendous interface that never works. I figured Xeons are the best bet, but im not familiar with the best low-cost Xeons and their respective motherboards. Anyone want to help out and throw around some links? Im fine with ebay and stuff. Im thinking if anything the case might have to be purchased new so I could get a nice small form factor case or something. Smaller the better. Power efficiency is also important here.

A friend of mine recently got a 1070, and he gave me control and let me overclock it(all my friends know I like overclocking, and he knew if he was getting a brand new 1070 I was gonna have to ). I was pretty impressed. stock, he was scoring just around 17,000 on Firestrike (+-100). It was extremely easy to get to 18500, and with some extended tweaking, I managed to get it to score 20,020. That's a score increase of over 3,000 points, and I wouldn't even consider it a unreasonably high overclock, pretty damn awesome if you ask me. On my 390X getting an extra 1,000 is a very high overclock. I like the 480 a lot, its price point is nice, and I have been wanting to downgrade, but seeing scores this high might make me have to pick up a 1080...

So I've been seriously considering dropping down a tier of performance for my gaming PC (listed in my signature). Since building my server, it really has nullfied the need for my 5820k (and now I also rarely play games). As fantastic as my X99 PC is, and as much as I love it, it went from not being utilized much to pretty much never, its seriously overkill for my needs and anything I would need it for my server can do twice as fast. The items I would be selling would be my CPU, motherboard, RAM, CPU cooler, and PSU. Whats the lowest I can downgrade my CPU/motherboard and still be able to power the top-tier GPU for the next 1-2 years? i5-6500? I would like to go to skylake for the newer tech but im fine with something like a 4690. I will probably sell my 390X and get a 480 (or two!) if it lives up to expectations as well. How much money do you think I could make selling my 5820k, motherboard, CPU cooler, power supply, and RAM if I sold them individually? I know my CPU is a good overclocker too, does that factor into its value at all?

So, its finally built. My dual Xeon server. The specs are: [CPU] [Intel] 2x E5-2670 Xeons (8 cores, 16 threads each) [RAM] [Samsung] 74GB of ECC Registered memory ( 7x 8GB sticks, and one accidental 16GB stick, thanks) [Motherboard] [Supermicro] MBD-X9DR3-LN4F+-O (dual socket, 24 RAM slots, quad gigabit Ethernet ports, IPMI port , EEATX form factor) [GPU] [AMD] HD5870 (I didn't settle for anything but the most high end GPU from 2009) The why: Im a high school student, currently taking a college computer networking class through a program my school runs with local colleges. I've been into gaming and computers for >5 years and I've really taken a liking to computer hardware and computer networking. It started as a pipe dream with a friend in a java programming class, and its evolved to be complete build of which we split the cost. I will be learning windows server 2012 R2 (provided for free by microsoft by giving me a DreamSpark account) and hosting many servers for me and my friends (some are into computer networking, some are not) including but not limited to: Teamspeak server, PLEX server, minecraft factions server, tekkit classic server, ARK server, DayZ server, Arma 3 server, as well as hosting multiple websites for each server once implemented and running. It will also act as a render PC for video as well as model rendering for all my friends and me(some of whom are into video editing with much weaker PCs). Friend who are in computer networking with me I believe have legitimate uses (there are a lot of students, not all of whom I trust ;).) will have unrestricted access to the server to play around with themselves so we can all benefit from this machine, as in the classroom we simply don't have access to a server. Planned upgrades: 9TB HDD storage upgrade for uses with PLEX and torrents, 128GB RAM addition, PCI SSD addition, RAMdisk, Quadros to aid in rendering. Comments: So I'm extremely pleased with the build. Its very powerful (1990-2020 Cinebench score), and will do what I need very well. I definetly went overkill on CPU cooling, and I did it for the looks, not gonna lie. It actually reamins extremely cool, sitting at a mere 50-55 C after 16 hours of 100% CPU and RAM usage. For the price I paid (~$950) It is quite the machine. Since building it the motherboards needed for it have seen a sharp price hike, I grabbed the last one of this motherboard from Newegg. One of my fatal oversights in this was my overlooking of EEATX vs EATX. Luckily, I have a little bit of design experience as well as having a family member who does CADD for a living and has access to manufacturing machines, its a plan in the coming months to custom machine some parts as well as tap some holes in the current case to make it custom and fully support EEATX. This is something I want to do over buying a new case for the custom touch, and to get the case safely vertical before my HDD storage upgrade for a PLEX server. Its kinda weird being in high school and actually owning a machine of this type, but im very excited to own it and look forward to working with it and learning new things. I've actually been friends with a guy I meant playing eve online who does IT work and I've consulted with him and had some 1 on 1 talks about things and going over various server tools/features as he runs his own server as well as others for his work ( the internet can be a really cool place) and he has offered help on anything I might have trouble with. I've seen a lot of threads regarding building PCs like this, especially involving the E5-2670, and I gotta say, do it! My experience was great and im extremely pleased with the resulting performance. And here are the pictures: Finished Build- Parts laid out ready the night before (coolers assembled ahead of time)- The motherboard- installing RAM (incorrectly, fixed later) - CPU coolers installed (huge pain, lots of problems with the 212X dual fan, notice the hot glue!)- Major oversight, EEATX doesnt work in EATX, read more carefully! Did this for a post test before I left for the weekend to hang out with friends- It works if it lays on it side, case modification set for the future to fully support this motherboard, bending of some metal was required for the fit, motherboard secured by 4 screws right now- 390X installed while my main PCs motherboard is out for RMA , drivers wont install, so its since been switched to a borrowed MSI GTX760 so I can play some games, but honestly even with the option I dont play. Thats a nice score!-

So I recently bought 2, 212X dual fan coolers for my dual Xeon server. The heat-sinks themselves work great; once they are installed, after a 16 hour CPU and RAM stress tests the CPUs held a solid 53-56 C. What I have a huge complaint about was installation of the extra fans. For one, these fans do not come pre-installed, you do it yourself, and my experience doing so was awful. First off, the fan connects by screwing on some plastic brackets which then clip on to the side of the heat sink. The holes which I was supposed to screw in a screw to secure the brackets were not threaded. On both coolers, two packages, the holes were straight through. How do I thread in this screw then? Well I tried, and the holes are either too small or the screws were too big on top of this. There was nowhere for the thread to go. After 40 minutes of desperately trying, I realized it was not happening and I certainly was not getting the screws flush with the surface for proper installation and certainly not happening 8 times, and was forced to hot glue the brackets on and completely ignored the proper installation (which worked great). I get that more difficult and universal installation is the price you pay getting a budget oriented cooler, but mine was literally impossible to install the correct way. Also on a side note, the manual also instructed not to use some extenders to install the cooler on a 2011 socket, which I found impossible and had to use the extenders to get the coolers on anyways.

Im building a server with two e5-2670s, and using this motherboard. Now, my main question is can I overclock without damaging the motherboard or CPUs (its not a standard motherboard). What would limit this? Can I monitor temps on the motherboard to make sure I don't overheat anything (with a laser, not through OS) and I'll be fine? On another note, are there components are the motherboard I could stick heatsinks on to have better thermal performance? I don't care if it doesn't overclock well, just that if overclocking will damage it. I can't have a dual CPU system and not overclock if its safe.

Messing around in Solidworks, trying to bend a part with the Flex command, however, it appears my trim planes are not working. I've tried it on different parts made different ways and no matter what I do it simply bends the part around the axis ignoring the trim planes no matter where they are, it bends the areas outside the trim plane. Some pictures to illustrate the problem

had the unfortunate opportunity to have to re-seat my CPU. Got some sweet pics of my 5820k I never took before I initially installed it. X99-UD4 needs to be RMA'd, but man does the 5820k look good in pictures. idc if you use these pictures anywhere, just credit me. anyone have any idea who I can contact at Intel to give them these pictures? I dont use twiiter or facebook.

So I have parts coming in to build a server. Pretty much the only power hungry things in it are 2, e5-2670s. After a 1-3 minute power outage 20 minutes ago, I figured I should just look into getting a UPS for mine and my server user's sake. Im really trying to keep the cost as low as possible, but seeing what $50,$100,$150 ect would get me is useful because If I know I can get a lot more for only $50 more I will do it. I thinking I really only need a 250-300 watt UPS to power my system (the server does have a 750W PSU though, shouldn't matter as it will never draw that). Browsing newegg, I was pretty confused. Pretty much every UPS has 6-8 outlets. I really only need 1. Can I save money by not getting one with so many outlets? I was also confused by specs. There are soooooo many UPSs that appear to be all extremely similar and at prices varying 1-3$, especially ones from CyberPower. Same with my knowledge of power supplies, advanced knowledge is something I don't have and its the same with UPS's, I'd rather make a decision with some community input. I will probably be making 1-2 other posts in the next day or two about UPS's, I got other questions, but not for this thread.

So I recently RMA'd my PSU (it was actually in error, long story) and I just had to mention my experience with Cooler Master support. It was fantastic. The only RMA I have done other than this was 2 times with my GPU through MSI, and Cooler Master's support makes MSI an embarrassment in terms of customer support. I went on cooler master's site, first registered my PSU, and when submitting my RMA, it allowed me to auto-fill all info relating to my PSU (warranty, serial number, model, purchase date). My RMA was accepted within 24 hours. I had difficulties finding the RMA form I needed to print (it wasn't obvious) so I contacted live chat, at an awkward time (like 9:30 p.m EST, I was surprised they were online) and got help within 30 seconds, and within 45 seconds I was greeted with a hello and an apology for the thought-to-be-faulty PSU and a link to the RMA form I couldn't find a link to. I made a suggestion to have the form sent to you in the RMA accepted confirmation email (MSI does do that) so you don't have to find it on their website, and was told my idea was pretty good and was forwarded to IT. Fast forward a week, I discovered it was not my PSU through indirect means (again long story, look at my posts). I contacted live chat again, and when talking it auto-filled all relevant info by automatically finding my current RMA (not having to re-find and type the serial number and various info was very nice, with MSI I was constantly filling out repetitive forms when dealing with support). Again, within 30 seconds (and at like 9:00 pm EST) I was connected, and within 60 seconds I was told the US RMA department is closed but he left a note on my RMA, and I was done with support. It took me 2 minutes from sitting down at my desk to having the issue handled (with MSI it was days and days of back and forth emails). Within 24 hours I got a email from the US RMA dept saying my note was received and they would be shipping the PSU back when they got it, the next day I got notified they got my PSU and that same afternoon it was shipped back and I got my tracking number. Just thought my experience was definitely praise-worthy, amazon-support level quality. I was really impressed, good job Cooler Master.

So Im having issues with my PC, its one of two things, its either my GPU or PSU. Doing lots of googling, people seem to think its a PSU issue (under 100% load my PC lags, then 2 seconds later freezes and then 2-3 seconds later gives a black screen and I must reboot, this happens when doing stress tests of playing games on my GPU). Using HWmonitor, my voltages for my PSU when in windows are waaayyy off, like +4v on my +12 V rail. But on AIDA64 and my bios, the voltages are well within tolerance and Hwmonitor seems to be regarded as inaccurate (but that inaccurate?). I've tried another GPU, a 5870, and games play at like 2-3 FPS compared to before when I had my GPU out for RMA it managed it at 60 FPS no problem (60 FPS cap), the thing is I had no drivers, as when I installed the proper drivers for the 5870 during install I would get a black screen (not for a few seconds, 15+ minutes) and upon restart no bootable device found, 2 hours later and a CMOS reset, motherboard repair, safe mode launch and a wipe of display drivers, my PC is working again but with the same issue of freezing while under load. Its worth mentioning that occasionally right before the freeze I see a frame or two of artifacting. Another note I can stress test my CPU just fine, but my GPU is way more wattage so I can't be sure, It could be because the GPU uses much more power from my PSU when stress testing. The problem is my GPU, a 390x, is a replacement for my artifacting/freezing 7970 lightning, which was a replacement for my 7970 lightning. I either really ****ing unlucky or something is wrong, and at this point I feel that if I ask for an RMA MSI is going to think im lying, and honestly if I were them I would too, how do I get 3 bad GPUs (although after receiving my 2nd RMA they did confirm it was a bad chip)??? So what is everyone's opinion on this? Could it still be my PSU even after I think I verified voltages are fine? In the 2-3 seconds I can run a stress test, voltages maintained fine on my PSU. I have overclocked all of these GPUs, but they are all the high end overclock-able tier GPUs (especially those 7970 Lightnings) and the OC's I have done have barely up'd the voltage and are way within the boundaries put in place.

The 390X I got from an RMA card 5 months ago has started failing. Its definitely the GPU (Look at post history, lots of backstory). MSI won't RMA it because the 7970 Lightning which it was an RMA for ( a three year old card that I had to RMA twice before I got a newer replacement for failures, although they artifacted, this 390x is failing differently) exited its warranty the same month I got the 390X replacement, so my 390X is considered out of warranty pretty much the week I got it. It seems I can get a 290X for $200-220 for a reference cooler, which I would prefer so I can eventually crossfire a 2nd one and have more managed thermals, and a uniform look. Any difference between brands of reference coolers or issue crossfiring them? I know its a very hot card especially with a reference cooler but I don't care about the heat im just looking for the best price/performance while I hold off for hopefully Polaris. My PC has no integrated graphics and Im not waiting 1-3 months without my PC working. Is ebay the place to go? Whats the best place to go to get the cheapest price?

What are other headphones that are like the Razer Hammerhead V2s? I really like the design and look of them , but I feel $50 is a lot. Are there any competing products that are the same and cheaper , or better and the same price? I know Razer tends to make some nice stuff but it's usually pretty expensive for what it is, and I'm not an audio person so I'm not familiar with other brands or products. The one thing that really makes me want them is the look , I really like the contruction and design of the Hammerheads.

So I finally got around to making a keychain out of a CPU I failed at delidding (Pentium 4 was the one used) after seeing some other people make CPU keychains, and finding myself with new keys and nothing interesting on them. (Pictures were taken with my phone this time around so they aren't that great) I like the outcome. I like it being delidded so its just the metal, and the fact that there is silicon still soldered on to the IHS makes it that much more interesting. Might end up coating the silicon in something as its got a small crack in the center that could eventually grow and make it not look as good. Maybe ill put on the Q6600 too but I would definitely need to coat the silicon in something (epoxy?) to avoid large amounts of chipping. Any ideas for other interesting computer stuff to put on it? Nothing big (entire stick of ram) or really heavy.

I use Psiphon(a proxy) to get around my school's filters. In networking terms ( I am interested in a detailed explanation of whats happening), what exactly is going on that allows me to access whatever on the network? I understand it changes my public IP address, but I dont think that would really matter it terms of blocked websites as they aren't blocking the user IP's.

So on my server I've had IPMI set up, it worked fine with everything including remote desktop control using my gaming PC. Its been two weeks with my gaming PC down for an RMA, its now rebuilt. The problem is now when I go through IPMI from my gaming pc, I cant remote control it anymore. I get "500 internal server error". The only changes have been the display driver, it was the integrated, then i put in a 760 and then a 5870, tried IPMI with 5870, realized it was based around the integrated graphics so I took out the 5870, and then I could see the desktop in the IPMI preview of the server, but still got the same server when trying to remote in. Nothing has changed with the IPMI configuration, so im not sure whats causing this problem. Walked away for 30 min, came back, now the preview inst even popping up using the integrated graphics. The server is definitely running with a desktop and everything, its right beside me.

Can I not use IPMI from a different network? I've configured and got it working for my server via my local network connecting from my main PC by typing in 192.168.1.240 (my server IP) and it works, but if im not at my house, how can I connect? Can't find anything on it, it seems maybe I use IMPIcfg utility, but when i download it from SuperMicro and run it, the run window goes away and then nothing happens. Running Windows server 2012 standard.
