So this started happening about 2 months ago after leaving my computer untouched for a month(I was on vacation). I noticed that despite running the exact same OC settings my scores in benchmarks and games are consistently about 5% lower. Not a huge amount I know, but its very consistent. I just can't seem to figure out why i magically lost 5% of performance.Things I've tried:-older drivers-fresh windows installation-editing power limits in Kepler bios tweaker-cleaning the graphics card-different OC software
-different motheboardNow here's the frustrating part. The power limit seems to be literally stuck. I've tried monitoring it with GPU-Z and it always throttles at 240-250W even if I set the TDP to like 500W in the vbios.Also MSI Afterburner shows different values compared to GPU-Z which actually scales properly with vbios power settings. For example MSI afterburner will always show 99% power usage at 250W no matter what its set at in the vbios whereas GPU-Z will show for example 80% power usage if its using 250 and its set to 300W. None of this matters though because I'm constantly power limited and its very frustrating because it prevents me from a higher OC(currently running only 1150mhz). The power supply is a 550W from XFX so pretty decent.
Any help would be greatly appreciated.
