Z68A GD55(B3) OC settings Check please.

[jeckulz]

Bit of a noob at this so I pulled the settings direct from an issue of CPC, but they were set up for the p67 variant, not the z68. The efi is pretty much the same though so it seemed logical that they were interchangable

It seems to run nice at 4.5Ghz (2500k) and temps peak @ 61 after 90 mins of Prime95 blend.
My only concern is that the VCCIO and VCCSA seem to be a fair bit higher than other settings than Ive looked into for a stable 4.5Ghz OC.
I just dont want to prematurely cripple the CPU or board.

Thanks in advance

I think we have similar board. These are my oc settings, been stable for more than a year. I play Dirt 3 / Metro 2033 / WoW / BF3 / Batman: Arkham City without any problems. Hope you find it useful.

Why were VCCio and VCCsa even changed? You should be fine with their stock voltages...

As I said, Im a noob

P67/Z68 settings will not change. leave the VCCio and VCCsa to auto or set the voltage manually to their stock settings.

hello I was seraching internet for z68a gd55 B3 and i5-2500k OC. I was doin the same as u wrote here. I did not understand this: DRAM Configuration 2T-9-9-9-24 Everthing else [Auto]

When I enter DRAM section. I should enter these values from top to down rand leave everything else auto right? Thank you

 

[EarthDog]

That depends on what ram you have and what its stock settings are...Usually the 5 primary timings are in order... 9-9-9-24-1/2T (command rate).

Do not mindlessly enter the timings. Make sure what you are adjusting is the right parameter. To help you out, download CPUz. Look at the memory and SPD tab. The memory tab is 'current' settings and the SPD tab is what the memory 'should' be set at. You can post the pictures of those tabs here using the following method...
