Hi guys. I would like to get your opinions on this thing.
What happened
My room is very hot and I don't have air conditioning. Few days ago I started getting these square artifacts all over my screen, while I'm in-game. When the artifacts show-up, the screen and sound freeze. Sometimes I have to reboot my PC, other times after 20-30 sec, the screen goes black for 1 sec, and then returns to normal, but the game is closed. These artifacts also show up after 10-20 sec of running the PCI render test on GPU-Z.
The artifacts look like these ( https://i.ytimg.com/vi/qVkE04C61Ys/maxresdefault.jpg ). Few times I got them very extreme, either taking all my screen space or having red vertical lines.
Other times the artifacts randomly show up while I'm not playing and one time they didn't disappear on restart and were visible on my boot screens.
My temperatures never exceed 76 degrees celsius (that's for the gpu core, I don't have sensors on the VRAM).
Fun fact: Strangely I had no problems when I played Stronghold Crusader (very old 3d real-time strategy).
What I did
After some reading I got to the conclusion that the problem is with my VRAM, so I decided to underclock my GPU memory from 1800 MHz (default stock clock) to 1100 Mhz.
Now I don't have any problems when I'm in desktop mode (browsing, watching movies, etc.). The GPU-Z test now runs without the screen getting artifacts too, but the animation is laggy, whereas it was very smooth at 1800MHz.
I have not tested the new settings in games (afraid that I might further damage the ram chips).
My graphics card is Palit GTX 460 1GB Sonic (famous for its lack of heatsinks on the vrm mosfet chips). Today I purchased Enzotech BCC9 heatsinks, and a Prolimatech PRO-BV14 140mm Blue fan for the side panel of my CM HAF-912 Plus case.
The question
Do you think that after I install the fan and the heatsinks I could probably return to my stock clock values without getting artifacts and freezes in modern 3d games? Or do all my problems mean that my GPU is inevitably dying?
Thank you!
