I began playing Bioshock: Infinite the other day and on the second day of playing I experienced a BSOD after an in game freeze. Looking at the minidump, it blamed the BSOD on nvlddmkm.sys, or basically something related to nvidia.
I already had the latest drivers but I did a driver sweep and reinstalled. I have not experienced the BSOD again but this made me curious and I began monitoring temps while playing.
While under very little load (web browsing etc), or idle, both GPU's sit in the low 30's, mid to high 20's (C). I know these are great temps.
When under load in Bioshock: Infinite on Ultra with FPS limiting disabled, or a GPU benchmark such as Unigine 4, my temps spike up to the low 80's C. These seem high compared to most reports and worry me- I've seen it go up to 84C, and think overheating might have been the cause of the earlier issues. Fan's max out at 60% and are on auto. Most people are saying they average around 70C under full load in BF3, though I do not have BF3 to test.
It is probably important to note that while the games are played on one monitor, I am running dual 1920x1080 monitors. Normally a web browser is open on the non-gaming monitor.
My rig is built well with very little obstruction and proper airflow, including aftermarket top fans and a removed lower HDD bay for more open space. I'm not sure what's going on.
Can you try single GPU setup and benchamrk both cards with Furmark burn in? It is probably bad GPU. Experienced that in the past with your symptoms and Nvidia GPU.
Before I go about this I just have a question: are you saying you think both my GPU's are bad? although normally only one has temps in the 80s, the other is still high 70's (78, 79). Also what exactly might be bad with the GPU? It seems to function and idle just fine.
Well I feel a bit silly... I just turned on the fan curve in Precision X and now both my cards stick at around 60-64C while under full load. This is with about 60% constant fan speed, as adjusted by the curve. Why is that not enabled by default? My fans were apparently running awfully slowly before.
Will this cause any adverse effects? Such as a shorter card life before the fan dies?
