2600k 1.45 volts to reach 4.5GHz?!?

post #1 of 23
Thread Starter 
I must be doing something wrong.

My rig is in my sig. It takes 1.45 vcore to hit 4.5Ghz, temps are fine at a max of 58c on prime95. But when I bump it to 4.6 GHz it won't even boot to the BIOS.

This can't be right?! Any help would be appreciated!

Update FIXED!
Problem was fixed with the following:
PLL 1.709v
VTT 1.129 (sweet spot at 5.0 GHz)

Need to test for stability but I'm at 5.0 Ghz with temps at 61c and a Cinebench 11.5 score of 9.65

Thanks to everyone who helped!

I don't think any chip could be that bad. I suppose weirder things have happened.

I once had a bad egg of a 2500k when building a rig for my friend and it required high vcore to be stable (1.46 for 4.4 GHz) called newegg and they said i could RMA it and the new chip was perfect with 1.35 vcore with 4.7 GHz stable.

Man, Sorry to here that. I have the same Mobo, so I might be able to help. Have you tried the auto overclock settings to see if it will boot with those? Also can you post a screen of your current Bios OC Tweaker settings?

I posted pictures above. Just tried the auto OC to 4.8 and it won't boot


EDIT: Tried auto OC to 4.6, won't boot

way too much PLL. lower that to 1.55-1.6. set QPI/VTT to 1.1 and DRAM voltage to 1.6. set LLC to maximum and vcore to 1.45. internal CPU PLL overvoltage should be turned on. set 47 multiplier and try.

It is possible that you have a lemon of a CPU but try that.
