OK, so I recently built my first custom gaming computer and I have done a lot of prior research on stuff like overclocking, but I am stuck. So my build is:
CPU: i7 4790k (Not overclocked)
MOBO: MSI Z97s SLI KRAIT EDITION
PSU: Corsair CX600M (I know, I went pretty cheap on the PSU)
GPU: GTX 970 G1 Gaming
Obviously there are more components in my computer but I believe that's all that matters for overclocking my GPU. So I began by updating all of my drivers, downloading GPU-Z, core temp, MSI Afterburner, and Unigine Heaven Benchmark (the free version so non-pro). So first I ran the benchmark at stock speeds with fans at 80 percent (I don't care about noise) and got a nice core clock of 1391MHZ. Then I went ahead and did a 100MHZ overclock on the core leaving the memory and the power limit untouched and still at 80 percent fan speed and got a stable 1492 core clock and max of 61C and a max of 82% TDP. So I turned it to a 150MHZ overclock and ran it again getting a max power of 83% and max temp of 62C. Then when I turn it up to a 160MHZ overclock, I get a lot of artifacts and my power limit is still at around 85 percent? Temps are still in the low to mid 60's so I don't understand why I'm getting artifacts? Everything I read and every video I watched showed that you keep increasing clock speed until you get artifacts, crashes, or a temp you're not comfortable with. So my question is, why can't I hit a 100 percent power limit? Is there something I'm doing wrong or is a different part of my system bottle necking the overclock? Any answers or suggestions are very appreciated! Thanks in advance!
