Quick question..

post #1 of 12
Thread Starter 
This is my first time really overclocking. I have taken the time to read the forums and new members posts but i cant find the info im looking for.

My Motherboard is a A88xm and my CPU is a 860k, when i up the multiplier in the bios, the voltage is automatically going up. ill boot back into windows and lets say i have the multiplier set to 44, the voltage will jump to 1.52v.

Why is the motherboard automatically upping the voltage? i probably missed a setting or something but i cant seem to figure it out.

Did you manually enter Vcore into Bios or is it on "Auto"?
That would be my first guess.

Need to know all what has been changed in your Bios so far (from default)

i keep searching online.. and the more i search, the more i just might think that my motherboard may very well be a turd.

I would guess (don't know MSI Bios) you will want to look at CPU Core Control. My guess is this is Vcore.
DL HWinfo64 (free), look at "Sensors" and under "Maximum" tab, look at "Core #0 VID" value. This is your CPU VID stock factory set default Vcore setting.
Input this value into Bios for Vcore as a starting point and start over with raising the multiplier .5 followed with a stress test. If it passes raise another .5 and re-test. Rinse and repeat.
See how high you can get with no voltage increase and keep a very close eye on temps.

You'll also find the CPU/NB VID listed as NB VID in HWinfo64 and use this as a starting point for the CPU/NB voltage manually entered into Bios.
The fewer items left on auto the better off you'll be.

it's not the best overclocking board, but at least it has a sink on the VRMs. Following sandman's advice I'd also see if you could get an old CPU fan blowing on the VRM sink. 4.4Ghz may be a little much for the board depending on how little voltage you can get away with. 4.3Ghz is a more realistic target. Anything lower should be no problem once you get the stable voltage dialed in. Just takes patience and many stress tests.

What cooler are you using BTW?

I checked under core control, that is a thingie where i can control how many cores are used and thats about it. Im thinking the voltage MAY be forced automatic. i guess i could technically go into AMD overdrive and drop the voltage but I'm not to keen on the idea of adjusting any overclocking stuff with software vs bios.

4.3 was my original goal, if i can hit that it would be awesome, but i know pushing it that far had the motherboard putting the cpu voltage to like 1.48, if i can get 6-12 months out of a $60 processor hitting 4.3 it won't bother me a bit lol

software is less preferable to BIOS settings unless your BIOS simply doesn't have the settings you need. You might see what overclocking utilities MSI has for that board, they may work better than overdrive.

Have you explored CPU Specifications and CPU Features? Maybe there's a "Advanced Mode" for Bios (Asus has this)
There is a way to adjust Vcore.
If nothing else you could hit up the resident MSI expert http://www.overclock.net/u/91085/cssorkinman and politely ask if he would chime into this thread.
