Core components:
- I7-4770k
- Gigabyte GA-Z87X-UD4H (F9 bios)
- 16gb g.skill Trident 2400 CL10
- Noctua D14
Have been at an OC wall at 4.3Ghz for some time. I delidded the 4770k (dropped temps 12c degrees). This gave me room to up vcore to 1.28-1.29 and keep good temps but I still failed stability testing at 4.4Ghz. For testing I look for 2+ hours on both Prime95 (v26.6) and Aida64.
I have followed several guides, turned of XMP running the RAM at 1600, keeping uncore fixed, upping Vrin, etc. and nothing has got me stable past 4.3.
The tweaking has got me a very comfortable 4.3 OC at 1.20 vcore and my RAM back at 2400 (1.575v for memory) with temps during stressing hitting low 60s.
Mobo oddities – it seems there is no way to set a fixed vcore on this board. If I set vcore to say 1.20v (cpu offset is greyed out), stress testing puts voltage at 1.212. To get vcore at 1.20 (running), I set it to 1.19 in bios.
OTOH if I set vcore to NORMAL, I then have the option to enter CPU Vcore offset – if I set it at 0.0v, and run Prime95 I get a running vcore of 1.18v; if offset is at 0.02, I get a Prime95 voltage of 1.20 – makes sense. The real surprise was running Aida64 with this setting – vcore went to 1.34!!! Both P95 and Aida put the CPU at 100% but Aida causes vcore to spike – I presume that the GB ‘Normal’ is equivalent to ‘Adaptive’…???
Is there any way to set a fixed manual vcore on this mobo?? Any suggestions on other OC tweaks?? I don’t think it’s worth going to 1.3v to get to 4.5 (if that would even do it) vs a very comfortable 4.3…
