This has been an issue I've been trying to figure out myself for the past 4-6 months. Its strange how it comes and goes.
What's happening is my GPU(s) are not reaching their full clock speeds (on or off boost) while under load (in this case the Fire Strike benchmark). This started roughly back in August/September with my GTX970.
I bought this card when it was new and gave it a modest overclock out of the box. When issues started arising I noticed chugging frame rates in render intensive situations. I started monitoring clock speeds (first with ASUS GPU Tweak then MSI Afterburner) and noticed that my clock speeds were WELL below what I had put them at and had been stable with up to this point. Below is what they were running at compared to what they were supposed to be running at.
GPU Clock: 630Mhz (1390Mhz)
Memory Clock: 4200Mhz (7750Mhz)
I went straight into cleaning out the video drivers with DDRU and re-installing them fresh. This would temporarily solve the problem, but it would arise again within a weeks time. The 2nd time it happened, I re-seated the card along with removing the drivers. Same situation; after about a week the problem arose again. The 3rd time I moved the card to a different PCI-E slot, cleaned out the drivers, dusted the entire system out (earlier than I usually do as I dust my rig out every 2 weeks) and re-installed the drivers. Same scenario. GPU performance dropped after roughly a week.
At this point I figured that the GPU was crapping out. So around Christmas time I picked up an Asus 1070. Up until last night, this card has given me no issues. Last night however as I attempted to game, I noticed that games that normally run with no issues what so ever suddenly started chugging. I brought up GPU Tweak and saw once more that clock speeds were not hitting what they were supposed to be hitting. This time, only the GPU clock wasn't getting up. The memory clock performed exactly as intended.
GPU Clock: 734Mhz (~2000Mhz)
Memory Clock: 8000Mhz (8000Mhz)
The 1070 is NOT overclocked. At this point I'm eyeballing either power delivery or the mobo is on its way out. Below is my system specs:
Mainboard: MSI Z77 Mpower
CPU: Intel i7 3770k (overclocked to 4.2ghz)
GPU: Asus GTX 1070 Strix
Memory: Corsair Vengeance 16gb @ 1600mhz
PSU: Thermaltake Smart Series 750
What I did last night to try and solve/find the issue. None of which had an effect.
Cleaned out/reinstalled graphics drivers.
Dusted entire system.
Swapped PCI-E slots
Swapped PSU Cabling
Swapped/Reseated Memory Modules
Removed ALL CPU overclocks.
Right now I cannot remove individual compnents to test them in other systems. At this stage I'm considering the nuclear option and replacing the mainboard, cpu, memory, and psu.
