M4A89TD PRO/USB3 Voltage Issues

Hey guys my motherboard has been playing silly buggers with me. I have VCore set to 1.47 in BIOS but the most I ever get in CPU-Z is 1.452 and it fluctuates around like crazy, sometimes as low as 1.392v. Now I'm sure some fluctuations are normal but this seems like a awful lot (please correct me if I'm wrong).

I am running the latest BIOS, version 1101.

LLC off
AMD C&Q off
Turbo Core off

Is this a common issue and does anyone have any idea how to fix it? Maybe I have done something wrong?

the lastest Bios version is: 1606... I have the 1456 and I´d like it even when I have almost the same problem but is not that big diff between the jumps of the voltage.

Try enabling LLC for both the CPU and CPU/NB.

Enabled LLC and voltage went to 1.512v under load and stayed more constant so that seems to be working better....1.5 is on the brink of safe right? I might just stability test for a while and then see if I can pull it back a little.

Also, when I went to change LLC I noticed a setting called "CPU Spread Spectrum" set to auto (options Enable or Disable). I don't know what that is but could it have been causing my problems?

@k88 where did you find that BIOS I Can't find it anywhere on ASUS's website.

Thanks!

Both CPU and PCIE Spread Spectrum options should be disabled.

Edit: That 1606 Beta BIOS is for the M4A89GTD PRO/USB3, not the TD version of the board.

The only time I've seen it used to good effect was when someone was getting bad static/background noise on their sound card. Somehow the CPU clock was interfering with the sound circuits. Unless you're having some problem like this disable it ...
