I've had a custom built computer for about 2 years now with no problems whatsoever. I had a crucial c300 128gb SSD as an OS drive, with a few games and programs on it, and a WD Black 1TB HD as storage and for everything else. I also have an Asus Radeon HD6950 2GB Directcu II video card in there. Recently I decided to splurge because of upcoming video games coming out, and purchased a Samsung 830 256gb SSD to replace my OS drive, and to continue using my 128gb SSD for not as important games, and my 1TB for storage.
That was just some background info, what I have overclocked is my CPU, which has never been an issue. I just overclocked it through the motherboard's bios I believe. I have also overclocked my GPU. It's stock settings are slightly overclocked as it is, but with the dual giant fans I know you can push it quite a bit more. It's stock was at 810 GPU clock, 5000 Mhz Memory clock, and a voltage of 1.10. Before I had installed the new 256 SSD, and reinstalled Windows I was using Asus's GPU Tweak and was about to get my GPU clock to 950, Memory clock to 5400, and was using a voltage of 1.18.7. I had that set up for at least a year without a hitch, no freezing, no overheating, nothing.
Now that I've installed the new SSD as my OS drive, using my old SSD as an extra drive, and the 1TB as storage I set up my overclocking in GPU Tweak and everything has been going haywire. I set it to the same exact settings as I had before. When I'm on my desktop doing nothing but browsing, etc my graphics are fine. The only time it acted up was when I was trying to get my Window's experience score, and my display driver crashed and recovered. While it was crashing my entire screen was filled with dark, and light grey vertical lines for about 30 seconds before it went back to normal. I thought that was odd.
Now for the real odd part, since this is a fresh install I have a lot of games I need to redownload. At first, everything seemed fine until I noticed my download speed dropped from around 2mb/s to 200kb/s. It stayed like that, and never recovered. I finally gave up, and rebooted my cable modem, and the router. The speed recovered and I was back to 2mb/s for the rest of the night. The next day, I continue to download my games, and my speed was about right until later in the night. All of a sudden it dropped even lower to about 150kb/s. I wasn't doing anything differently than before, in fact I wasn't even working on my computer and had hardly any programs running. Now, for some odd reason I decided to pause the download, I opened my overclocking utility, and put my card back to default, voltage clock, everything. I resumed my download and it went back to 2mb/s. I paused it again, put my card back to overclocked settings. It went back to 150kb/s, it did this 4 times, and same results each time. This had dumbfounded me.
I let the game finish and decided to try to play some games for a few hours at the overclocked speed. First game I was standing still in the game, screen flashed to that grey stripes again for 20 seconds, and then I was back in the game. I played the game for about 40 more minutes without a hitch. I then tried another game for about an hour, no issues besides some lag. I then tried to play D3, everything was fine until about 20 minutes in and the grey stripes came back, but never disappeared. Then my computer froze, which I attributed to too much overclocking. I then tried running very briefly the same games at slightly overclocked stats, which GPU tweak has a game mode option which increased my GPU clock by 20, my Memory clock by 80, and my voltage by 10 (1.11). I didn't have much of a chance to test it, but everything ran fine and it didn't crash.
My computer stats:
ASUS Crosshair IV Formula AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard
AMD 6core CPU Black Edition
Coolermaster V8 heatsink
Ripjaw 8GB DDR3 (2 4GB sticks)
ASUS EAH6950 DCII/2DI4S/2GD5 Radeon HD 6950 2GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card
Sound Blaster X-Fi Fatal1ty Champion Edition
Samsung 830 256 SSD (OS)
Crucial c300 128 SSD
WD Black 1TB HD
Asus DVD/CDrw drive
CORSAIR CMPSU-750TX 750W ATX12V v2.2 SLI Certified CrossFire Ready 80 PLUS Certified
CoolerMaster HAF32 Case with 4 giant fans, one in front, one on the side, one on the back, and one on top. The fans directions were all placed by Coolermaster when purchased.
Windows 7 64bit SP1, all updated. Using Catalyst 12.4 drivers, latest release.
Also to note, my GPU was running a bit hot after overclocking, reinstalling, and installing some games. Only while in game though, but after taking it out and cleaning the inside of my case, and air dusting everything including the card the temps went down a bit.
So to sum it all up, what's going on here? My only conclusion is that possibly my 750 PSU is not big enough to handle that extra SSD, plus the overclocking of my GPU. My internet is also connected through the motherboards port. Could this be a voltage issue? Or something else? I do not have access to a multimeter.
Thanks very much for readying my wall of text, and look forward to some opinions here. If any more information is needed, please let me know.
