A little more than a week ago, I acquired an ASUS Strix GTX970 4GB OC. I've been noticing alot of sporadic stuttering whilst playing games and I'm kind of puzzled to what it could be. Very frustrating.
I've monitored my system with HWiNFO64 and saw no abnormalities in CPU, GPU and RAM usage. Nor did I see any in CPU and GPU temperature. A friend of mine said I should look for abnormalities in temperature as he suspected that throttling would be the issue. I've also run Furmark but did not observe any faults either.
What I am noticing while booting up or playing games, is that the VRAM usage indicator on ASUS's GPU Tweak 2 goes no further than 6% an most of the times just idles at 0%, which is why I suspect the GPU to not function correctly. Could there be something I've missed?
Could it be the the powersupply that I recently purchased? I felt the need to purchase a new powersupply as my old one only delivered only 25A on the 12V rail. The minimum seemed to have been 28A and it said 38A was recommended on the card's box. I had no money to buy me a really good one, so temporarily went for a Corsair CX600M. I know that the chance of the powersupply being the culprit is very slim, but I thought I should state the potentially necessary.
I'll state the specifications of my system below to give you guys more clarity on this matter and help you answer my (very) vague question:
- Antec GX300 case
- ASUS P8H67 Motherboard
- Intel i5 2400 processor
- ASUS Strix GTX970 4GB OC
- Mushkin 240GB SSD
- Samsung 500GB 5400rpm HDD
- Corsair CX600M PSU
The system was recently clean-installed with Windows 7 Ultimate edition. Games tested include GTA V, MS Flight Simulator X and CS:GO.
As suggested by Psycogeek, I have checked the current Link Width in the Main Board section of CPU-Z and saw something that might be remarkable:
The card installed into the lower PCI-E slot of the motherboard. Could this slot be defective? Should I try the other slot?
