Hello guys,
So I have the following situation: I have recently installed a second GTX 660 in my system and managed to run SLI (almost impossible task on a non SLI mobo with a crappy PSU, but with some rewiring and a software that enables sli on some unSLI mobos (called DifferentSLI - amazing little tool) it works fine even with the newest drivers).
The thing is that the most demanding games often crash (black screen, nvidia driver error). Since i've had crashes like that when i was using just the single Palit GTX660 and OCd it, i tried underclocking both by 10%. This completely fixed the issue.
I was lead by many forums to believe that this might be a PSU issue (mine is a really crappy brand (turbo-x) but says it is 750w, which i dont really believe).
I do not think it's the PSU and my wiring's fault because of the following. The Palit GTX660 was totally unoverclockable even on its own (+2% OC and games crash). The MSI 660 one on the other side, overclocks beautifully on it's own with no crashes at all (on the same PSU). So my question is doesn't that surely mean that i just got a shitty palit 660, or it still might be from the PSU, despite the fact that the MSI one can OC a lot with no problem ? If it's the PSUs fault, how come the MSI does not crash, and the Palit crashes when OC'd on their own?
I want to know this as I wonder, would I be able to OC the stupid Palit GTX if I got a better PSU?
