i5 2500K OC 4.5GHz @ Stock

post #1 of 21
Thread Starter 
Hey all,

Currently I'm running my i5 2500K at 4.5GHz on Stock voltage. When put through intel burn, completes all stable. Temps don't go above 50C

Whenever I try to change the voltage so I can OC a bit higher, it won't boot back up, whether I set it to Manual Fixed or Manual Offset.

Any Ideas?

Rig in profile

Thanks,

Ryan

I'm sorry but IBT and stable shouldn't be in the same sentence without a negation...

Mind supplying us with some more details as to how much voltage, the multiplier, LLC etc. you have set?

PS: Can't see your rig in your sig

Updated Sig.

Everything is running at stock, except the multiplier which is 45.

If i edit anything else, it fails to boot and I have to reset CMOS.

Here's an image of CPU-Z, Realtemp and IBT.

Well, 1.28 V isn't stock voltage. And at stock your voltage is probably on Auto so it increases the higher you overclock (at least my motherboard does (horribly)). Although I do have to say 1.28 is about right for 4.5 Ghz and if your motherboard set it like that on Auto then I'd just leave it on auto and try OC'ing further.

First I'd suggest you read up on some SB OCing info. I'm not an expert myself because I've only had this CPU and motherboard since Friday.

Secondly: Don't use IBT for stability testing. It didn't work on AMD and it doesn't work on Intel. If your OC is unstable on IBT standard then it's FAR from stable. Use Prime95 with custom 1344 and 1792 lengths (worked great for me) and then a long custom blend with more ram usage.

Take a look at these two threads.

You may need to turn on PLL over voltage to get past the 45 multi. Your chip may not boot past a certain mulit also. Mine will not boot past 4.4 for some reason.

Fair enough, As I said, all I altered was the multiplier.

oh..you have to disable the power-limiting..check the youtube guide for asrock settings..it's spot-on biggrin.gif..and..1.28v isn't going to run 4.5ghz....it probably instant reboots from not enough power..add vcore

I managed to get it to boot with a Multiplier of 50 and a Offset Voltage of 0.180mV

Running Prime95 now at 1344 and 1792

Temps steady around 60C

However, according to CPU-Z - the multiplier doesn't tend to go over x44 now.

Ideas? Have I done something wrong?

Post your BIOS settings.

Believe you can do screen captures by hitting F12 and having a USB drive plugged in. Sometimes easier than typing them out.

Using Prime95 - the multiplier eventually reached 49.

Using IBT, the multiplier is a constant 50.

I'll try and post some bios setting later - just about to go out.
