    How To Test VRAM?


      As the title says.....


      I've been getting random BSOD while playing GTA 5. I haven't seen it occur anywhere else.


      Is there a good way of testing my GPU?


      Win7 x64

      ASUS P5Q SE Plus: BIOS ver. 2204

      Core2 Quad Q8300 @2.5ghz

      8GB DDR2 800mhz

      Sapphire R9 270x 4GB

      X-FI PCI-e x1 audio

      Ultra 650w PSU

          I just ran the 3DMark 11 benchmark, without issue.

              What is the BSOD error? Your system is quite old and powered by a very scary 456w PEAK (when it was new) power supply. That would be my first guess at what is causing your issues. The second would be a faulty RAM module (not VRAM).

                  My power supply is 650w, not 456....lol. Also, when I bought it, Ultra had a lifetime warranty on it. As I said, it only seems to occur with GTA. If it was the PSU, would it not occur when ever I put a load on the system? If the benchmark didn't push it to the limit, I doubt the game will.


                  This is my exact PSU, it's not crap: Buy the Ultra LSP650 650-Watt Power Supply at TigerDirect.ca


                  I ran the windows memory checker thing, and it showed no errors.


                  I thank your for your help. If there is any more info you think would help to troubleshoot the issue, let me know.



                  EDIT: I just played GTA5 2 hours straight, no problem.

                      See, here's the thing: that PSU is a piece of crap. See their specifications:


                      AC INPUT

                      115V/230V - 60/50Hz

                      DC OUTPUT



















                      +3.3v and +5v have -very little- to do with modern computers. RAM uses either 3.3v or 5v, lower power motherboard components and some drives use 5v, PCI cards (not PCIe) use 3.3v, while everything else uses +12v. Back in the 90s everything was 3.3v and 5v, but not today. So with that in mind, you see where it says 38A MAX +12v? 38A x 12V = 456w, therefore you can consider your PSU to be able to provide, when brand new, a maximum of 456w. Capacitor degeneration will cause a loss of ~2% max power per year, so assuming you bought it even 3 years ago, it's already down to 429w. Now, Ultra is what you could call a "buy and sticker" manufacturer, as in they buy a PSU model in bulk from mostly crap manufacturers and stick their label on it. According to TomsHardware, which put together a pretty large list of PSUs and their OEMs, yours was made by Youngyear, and I wouldn't trust them to power my rig.




                      Games and benchmarks put different loads on a system. 3DMark is built to put an unrealistic load which can cause a system to be under less stress than a game, especially given the age of your CPU.


                      That type of BSOD says to me RAM and/or insufficient power at 12v.
