Hello, I just finished my build (second) and I'm just wondering if I got a bit unlucky with my cpu.
specs:
cpu: i5-4670k
mb: asus z87-plus
ram: g.skill ripjaws x series
gpu: gtx 770
psu: seasonic 850w
cooling: custom loop with 480 total rad space and xspc blocks for cpu and gpu
So far I've only messed with the clocks and voltages when OC'ing.
I can get up to 4.0 ghz while leaving the voltage on auto, but it peaks out at roughly 1.23 when stressed with prime95 with the small FTT test with temps averaging high 50's and peaks around 61-62 C. To be stable at 4.2 the minimum voltage needs to be 1.305 and 4.3 it needs to be over mid 1.3, around 1.375 most likely. I stopped here after max temps hit 82 and I wanted to keep it below 80 ideally.
I think I have a bad cpu, but I also wanted to know is there anything I can change to increase stability while lowering voltages just a little? So far I have not touched ram timings, cache voltages and speeds, etc. I'm new to overclocking so I tried to keep it basic, but I think I have a good idea now what speed my cpu is capable of and I want to take the next step in tuning it to ideal settings.
Bonus question, anyone else with a custom water loop having the same temps at the voltages I'm testing at? I've read some people bragging about their 1.4v cpu's only hitting maxes of mid 70's etc. etc. I'm hoping I put everything together correctly and this is the most I can squeeze out of my system. I'd hate to leave stuff on the table if that were the case.
Sorry for the semi-long post, thank you for reading if you've made it this far haha
