Hmm I've been a bit wary of taking voltages too high, so never gone to the realms of 1.55v, max I've ever tried is:

CPU Voltage = 1.525v
CPU-NB = 1.375v
CPU VDDA = 2.70v
HT = 1.40v
HT Core PCIE = 1.20v
NB PCIE PLL = 1.90v
SB Core = 1.28v
Vdimm = 2.10v

So maybe I'll try having a more equal CPU + CPU-NB Voltage and try getting a higher NB speed... max I've gotten so far is 2400Mhz NB and 2400Mhz HT using 240 HTT Ref and x10 NB Multi and HT Set at 2.0Ghz (x10)

I'll try some of these higher voltages later and see if it yields higher clocks.

I'm using water on the CPU only, with the stock Copper HSF's for the chipset that come with the M3A32-MVP mobo, with the added fan to the HSF sitting on on the PWM's and a 40mm fan on the NB Heatsink..

I'll try the following settings, but would appreciate if you can confirm I've understood things right....???

That is to get better stability at high clocks needs:

  • CPU and CPU-NB Voltages to be HIGH and as close as possible with CPU temperature being the limiting factor.
  • Higher the CPU Clocks the higher the NB clocks need to be for stability
  • Higher NB Clocks need higher HT Clocks for stability.
  • And all the above need high volts to achieve stability... at cost of high temps.



The voltage settings I'll try:

CPU Voltage = 1.55v
CPU-NB = 1.55v
CPU VDDA = 2.70v
HT = 1.40v
HT Core PCIE = 1.20v
NB PCIE PLL = 1.90v
SB Core = 1.28v
Vdimm = 2.10v

With other BIOS settings as follows:

CPU Multi = x15/x15.5/x16
CPU REF HTT = 200
NB Multi = x10
HT Speed = 2.0Ghz (x10)
RAM = DDR2-1066

For:

CPU @ 3.0Ghz/3.1Ghz/3.2Ghz
NB @ 2.0Ghz
HT @ 2.0Ghz
RAM @ 1066Mhz


and also


CPU Multi = x12/x12.5/x13
CPU REF HTT = 250
NB Multi = x10
HT Speed = 2.0Ghz (x10)
RAM = DDR2-800

For:

CPU @ 3.0Ghz/3.125Ghz/3.25Ghz
NB @ 2.5Ghz
HT @ 2.5Ghz
RAM @ 1000Mhz

Any suggestions before I go ahead and try these out....?? Other than the obvious of closely watching temps etc....

Thanks for the info, given me soemthing new to try.... and at this point I'll try anything..!!!!.LOL
