Newbie and overclocking 2500k
- Thread starter Frank31uk
- Start date
Hi guys, sorry to hijack this thread, I am in the same boat as Frank31UK.
Newbie to the OC world. Spec:
Asus P8Z68-V pro
2500K
Corsair XMS3 8GB - 2800C9 1600MHz
What I have done so far is set the memory to 1600 instead of 1333 by default.
under CPUZ the vram is 1.65 (is this safe) ? can I set it to 1.5 ?
what is the max (safe) vcore at 4.5 ? how to set the vcore, by using manual or offset ? and what is the difference ?
Thanks for this thread it was helpful,
Regards,
M

If the ram will run fine at 1.5v that is the recommended setting, if not then up it until stable.
Anything upto 1.65v is supposedly ok though.
The max safe vcore has been stated at 1.38v but a lot of folks reakon 1.4v is fine for every day use.
You should be able to do 4.5Ghz with around the 1.3 vcore mark, it might need a bit more or less depending on how good the Cpu is.
I would use offset rather than manual, manual vcore will always stay at whatever you set it to even when the cpu goes into power saving mode.
Offset will reduce the voltage to 1v or less whenever the Cpu downclocks to 1600Mhz in idle mode.

ok I tried all sort of offset, currently running at 4.5Ghz @ 1.34 according to CPUZ and CPUID
All settings on AUTO except for CPU ratio and offset.
started at 0.030 went up to 0.050 at the moment every time I increase the offset by 0.05 it takes longer to fail in prime95.
Its gives me Round error 0. ###### numbers after 30mins on one core.
increase voltage ?
Note: no BSOD at all, just FATAL ERROR: Rounding was 0.5, expected less than 0.4
Edit after upping the vcore offset by 0.05 I get FATAL ERROR: Rounding was0.4982910156, expected less than 0.4
on core #02 after 35mins prim95

Is it 1.34v under load while running Prime95? if so thats quite high for 4.5Ghz
I know you set the memory to 1600 but did you also drop the voltage on it as well?
If so it might be the memory that is causing the error and not a vcore issue.
