So I traded my backup card, a GT 240, for a XFX GTS250 and though I would toss it in my system for a few extra ppd. Last night, both the 250 and the 460 were running fine until I checked this morning. The clock on the 250 is basically half (738 -> 300mhz checked via evga precision and gpu-z). Ppd dropped from 6k to ~1.4k. Not really worth it, but I can't override the half clocked settings.
At first I was thinking it was a power issue, but it could be heat related. The 250 has its own 6pin connect straight from the psu, a XFX 650w, which is a re-badged seasonic and is "SLI-ready". Normally the 460 runs around 50-60C and now its about 67C. The 250 was running around 74C. At about half it is running 57C. It was cool this morning, so not really sure what is going on.
For now the 250 is going to be removed. 1.4k is not worth it. Anyone have any ideas?
