Okay, so I've spent the last few days overclocking (trying) my GTX 670's. I maxed at out 1228mhz for the stable GPU clock, and a max of +588 on the memory, which is somewhere around 3590mhz.
However, I'm way over TDP. WAY over. GPU-Z is showing max TDPs of %137, with spikes to %387 right before a crash (I assume this is just an anomaly related to crashing, and meaningless). I get throttled around 129%.
So I figured, hey, not the best overclockers. Whatever, right? Well, at those clocks, I was getting throttled double. First, because I couldn't keep my temps under 70C, even at max fan, MX-4 TIM, and very good airflow through my HAF 922. Ambient temps was 72F. So I lowered them. And lowered. And lowered. Down at 1202mhz on the GPU and +400 on the memory, I'm still getting throttled, still breaking to 74C, and still hitting 132%+ on TDP.
So I revered to stock. Still can't stay under 70C; I'm slightly eeking to 71C-72C. Tried with side panel on and off. At +122% power target, I'm still seeing 125% TDPs.
Is there any way to get my temps down besides alternate cooling? Other people are getting 65C on reference cards at overclock, and I can't stay under 70C at stock. Bummed.
Is there any way to lower my TDP, or is this just the silicon lottery?
This cards have been a nightmare to OC. Nothing seems to make sense or work according to the guide. I might get 5 Heaven runs at a certain GPU OC; then I lower it by 3mhz, and I crash instantly. I did a few stable runs at +595mhz on the memory, then I crashed. Kept crashing all the way down to +588mhz.
I've looked around and have seen a few people with VRAM issues. They sound very close to home, because they all have: low, low OCs, high TDPs, high temps, and slight artifacting, even at stock clocks.
I seem to be getting all of these. When running Heaven at stock clocks, stock power, stock volts, etc, I still get slight artifacting. Textures will appear/disappear quickly, the clouds don't change color or form smoothly, rather, they do so in jagged lines. Some textures fail to load fully, like that scene where you are hovering over the house with the chimney. The detail on that chimney is always low res, as if it never loaded correctly.
Should I just be looking to RMA? How likely would it be that eVGA would accept both cards on RMA?
Or is there anything else that I have not considered?
Or maybe I'm a bloody idiot that has no idea what I'm doing. Feels like it.
