Area3 is Vmem, by the way

What BIOS voltage do you increase to get higher VGA clocks?

Massman · 29th May 2009, 21:08

Increasing the voltage of the NB core / Pci-e (which seems to be link, at least according to the bios).

Nu, Vigp != Vnb. 1.6v in de bios, is -wellicht- ongeveer 1.35v Vigp (andere mensen kunnen de Vigp wél appart instellen en kunnen 1.1GHz core doen op 1.38v.

And there are probable no datasheet available?

Massman · 29th May 2009, 21:49

Not of the CZ-AD 71A IC

What volts do you read at the MOSFET legs in area 2 and 3?

Massman · 30th May 2009, 00:07

None of the voltages seems to be related to NB/IGP/VDIMM/HTLINK

What do you read on them small mosfet and coils. Should be Vdimm around that area. Set it high enough in BIOS so you're not getting confused with onboard mem voltage.

Onboard memory is DDR3 and was set at 1.5v; increasing it to 1.7v doesn't change anything on the mosfet voltages

Can't get to the back of the motherboard since the northbridge cooler isn't fixed to the board. Two of the smaller mosfets read 2.12v (bios: vdimm set at 2.2v) and two measure a bit above 5v.
