Does my overclock look OK?

post #1 of 17
Thread Starter 
So i have been running my i5 2500k for a few months now at 4.6ghz @ 1.335v totally stable. I wanted idle voltage to drop with the multiplyer so i have been looking into overclocking with OFFSET voltage. Followed a guide and i can now run 4.6Ghz stable at 1.328v under load and 0.976v at idle....it seems to be 100% stable after several runs of IntelBurnIn and a few hours of Prime95. Can someone take a look at my settings below and let me know i have set it up correctly?

Also i cant seem to go any higher than 4.6ghz atall. My temperatures are good as can be seen in the screenshots below...how can i get a stable overclock of 4.8ghz? I have tried 1.40 and 1.45vcore and no luck.

Looks good to me, wish i could get an overclock like that my current just gets ridiculous

Thanks mate, what voltage do you need for your 4.5 OC?

I just installed an SSD so i reset my CMOS, so currently nothing but it needed pretty much a minimum of 1.365 v but before I re overclock I'm going to put on the newest (or best) bios/uefi for my board

Looks good Darylrese!

Try using Extreme on phase control, manual VRM and set vrm to 350, those two are the only settings I think you should change for optimizations.

The reason why you cant run 4.8ghz is almost certainly down to CPU PLL Overvoltage, turn that to enabled pal and it should work thumb.gif

Thank-you! + Rep. What will setting Phase control to EXTREME do? Do you mean internal PLL overvoltage? What does this do??

Turning phase control to Extreme, if i remember correctly, puts the load over all the phases rather than only some of them (in theory more stability), it says it in the uefi where you change it

To be perfectly honest with you im not sure what either of those settings actually do, phase control is same as duty control, always set to extreme. Its called either Internal PLL Overvoltage or CPU PLL Overvoltage, and again im not sure what it controls, but again this setting is renound for being a cause of overclock not getting past 4.5ghz. There was a thread from an ASUS rep with an SB overclocking guide, and that mentioned the need for the overvoltage setting to be enabled to allow for high overclock.

Awsome thanks mate. I'll give it a go! Does it automatically up your VCore by changing those settings or will i need to change that too?

No, PLL overvoltage and phase controls dont change your vcore. Thats determined by your setting, Offset uses whatever setting you have inputted and adds that to your cpu's VID to determine the vcore. To find our your cpu's VID, download realtemp and click on the box in top right, it will either be displaying 00:00:01, 100W or will say 1.365 VID etc etc.

Best way to find out your stable overclock is to test with prime95 overnight and use manual vcore, then once you know what vcore you need change to offset.
