Did I set everything correctly when OC'ing my 2500K?

post #1 of 6
Thread Starter 
I have the ASRock Extreme4 Gen3 P67 mobo and was wondering if I had setup everything properly when I did the OC. This is my first time ever OC'ing, and was going to put it at 4.5GHz, and I hope I didnt mess anything up. What I did was the following.

Multiplier - 45
Turbo Boost Power - Manual
Short Duration Power Limit - 250
Long Duration Power Limit - 250
Core current Limit - 250
VCore - Fixed at 1.325v

I didnt change anything else or touch anything else. Going to do a stress test overnight, but I've been gaming on it for the last 3 hours or so with no problems (I know that doesn't prove anything really but I do atleast its atleast a little stable to hold games). Did I miss any settings or anything?

You may want to refer to this guide for OC'ing:

http://www.overclock.net/intel-cpus/...king-tips.html

In particular, check out the parts for stability testing using Prime95 with 1344 and 1792 FFTs. You only really need to do each one for 20-30 minutes... not long at all!

As for your particular settings, I prefer using offset, since it allows the voltage to change when the CPU is idle. Just sayin'. Other than that, looks good!

Very nice guide you have, haha.

What about the tons of other settings you have up there though? Like PLL voltages and C3/C6 reports? Should I have changed any of those settings.

And I'm doing the 1344 test right now. About 15 minutes into it so far with no BSODs or any lock ups from what I can see. I'm on my laptop typing this by the way.

As for the voltage, do you think that is a bit high for 4.5? If I past both of these tests though at about 25min each, it shouldnt be a problem though should it?

Also, for the offset voltage, you said at times that the voltage can go a bit haywire and pump it up to way over what it should be, into the 1.5v range? Would it be best for the long term to just change it to offset now and do about +.173v (original vCore is at 1.152v) in the offset setting?

1.325v for 4.5GHz is very good IMO. My chip requires 1.4v just for 4.6GHz, so what does that tell you...

For the other settings, I wouldn't mess with them if I don't have to. As for offset, your voltage shouldn't be going haywire... at least not all the way into the 1.5v range. While stress testing, my voltage fluctuates anywhere between 1.4 to 1.412v, but never more than that.

Setting it to 1.325v manually is good for stress testing, but I'd use offset for everyday use (in combination with the power saving settings) because you CPU will often downclock to 1.6 GHz while idle, and obviously you don't need 1.325v to power that. Save money by saving on electricity man!

Ah, ok. I gotcha. How actually do I use offset? Just set it to offset and choose what I said earlier, which is +.173, or somewhere around there? That should be right at 1.325v. Also, will keeping it at fixed 1.325v cause damage when it downclocks?

And did the 1344 test for 30min with no errors, and am about 20min into the 1792 with no errors so far

Yes, that's exactly how you use offset, though I don't think you want +0.173v because mine is at +0.100v and it's already at 1.416v, so do you really want to have ~1.489v?

Try starting at maybe +0.100v first, then work your way down from there.
