M4A87Td EVO voltage problems

post #1 of 10
Thread Starter 
I have been trying to adjust my cpu voltage for a while now but I cannot seem to get it to change. If anyone knows how to set the voltage to 1.475 volts on my M4A87TD EVO motherboard it would be helpful to the utmost extent. If any pictures or information are required or helpful I will post them. Thanks!

Ps: I am over clocking AMD phenom II x4 955 BE to 4ghz

If the BIOS is anything like the one for my M4A89GTD, then you have to set the CPU voltage to manual and then type in the numbers using your keyboard.

Or you could use the offset function and add/subtract voltage that way.

@GuardianDuo I have tried that but the voltage does not change. Also how am i suppost to upload images it makes me enter a URL do I just upload them to something, if so suggestions?





Also I found out Cpu-z says im at 1.452v while Core temp says im at 1.375v but when I ran prime 95 at "in place large FFTs" Cpu-z said I was at 1.38. Agggghhh! I'm a noob -.- Sorry :/
Another thing is it best to add have 20 multi and 200 fsb or 18 multi and 225 fsb? Again, thanks!

I don't know about the multiplier vs FSB thing, I haven't aimed that high.

Also, the voltage drop could be due to vDroop. This M4A89GTD has quite a bit of vDroop, so your mobo might have even more than mine.

If you're confused about the grey and yellow numbers in your BIOS:
The grey number changes only after you Exit + Save Changes.

Don't trust CoreTemp's CPU VID thing.

Also, set that CPU/NB to 1.3v or something, and bump up that CPU/NB to 2600MHz or 2800MHz.

I'll work on this when I get home but how am I suppost to deal tith the vDroop thing. Speeking of vdroop I have never heardof it bust I assume it drops the voltage of my processor.

Yes, vDroop is where your CPU voltage drops when your CPU is under load.

My stock voltage is 1.35v, but vDroop causes it to drop to around 1.33v and 1.32v during prime95 and stuff.

You can deal with vDroop two ways: One, increase voltage so you idle at a higher voltage, or two, turn on the CPU Load-Line Calibration, which ups the voltage when it detects the CPU under load.

People are conflicted about LLC (Load-Line Calibration), since it's technically just increasing voltage, and it's random and inconsistent at times. It's your choice.

I'll try the load line calibration and see if that helps it was on at first but I heard to turn it off so hopefully it will hely keep the voltage in a more stable area.
Knowing me there's bound to be problems so expect another post.

lol, OCN is here to help with your problems, so it's OK.

I forget the settings for LLC, but I believe these M4A8__TDs had only 3 settings - Off, Auto, and On. Them other fancy motherboards have percentage settings, which are more useful.

Hopefully CPU-z is trust able. If so, it worked! Thank you very much for you help i'll mess around some more from here.


PS: sorry for my bad grammar earlier I was typing that on my phone

CPU-Z is pretty trustable, I use it for my voltage reading.

Enjoy your new 4.0GHz Phenom II X4!
