MSI A85XA-G65 motherboard question

post #1 of 7
Thread Starter 
Hello everyone! Working on making my 750k get a more stable OC, and was wondering what CPU_1.2v voltage is in the mobo bios? Do I need to take that off auto and should it match my CPU voltage? I would like to attempt 4.5 100% OC. Any other settings to mess with? I have disabled cool n quiet, c6 state, turbo core, etc. I have the CPU NB at 2500, and that is stable at 1.25v. Also OC'd my corsair vengeance to 1866mhz stable with intel burn test max setting, but had to drop my CPU down from 4.5 to 4.3ghz. I have placed vdroop for both cpu and nb to 100%. Also CPU voltage is at 1.45v at 4.3 ghz. Thanks for the help! Wanna go 4.5 full time on air.

It would be helpful to know your full system specs. Could you make a sig rig ?

What kind of temps are you getting with that overclock?

Ok, I have built it in rig builder. I am running 1.45v right now. Running at 39-52c and could probably drop the volts down a bit and still be stable

Ok so here is my dilemma, I can boot into windows at 4.5ghz, with intel burn test, even at 1600mhz, I can only do 1-2 passes before it drops a warning window saying it isn't stable. NB to 19-2200mhz range. I am pushing 1.5v CPU and 1.325v NB. It runs Arma 2 stable in 4.5ghz but I worry it isn't stable. My temps while loading IBT is max 52c. Is there nothing I can do to get it bench/stress stable at 4.5? Right now I am stable at 4.3ghz and 20-2200 on NB, with my corsair vengeance 1600 CL9 oc'd to 1866 9-10-9-27. And running 1.45vcore and 1.25v nb. Help!!!

You'll get people who will disagree, but it's been my experience that stability problems can start when temps get above 50 C. Could be the culprit.
What is the jedec spd rating for your ram @ 1866mhz? ( use cpuid to see it under the spd tab)

Okay, so I messed with bus speed, and at 105, I can get up to 4.4GHz, and 2300MHz NB. Running 19xxMHz memory. I don't know what else to do.... Scratches head..

JEDEC #2 518mhz JEDEC #3 592mhz, JEDEC #4 666mhz - slot 2 & 4.
