Asus P4B266 vmem mod

Hi guys,

I know that board is old, but if you happen to know the vmem mod for it, or know where to find it, please tell me. Many thanks :)

Hi

You can increase memory voltage by connecting all Vmem jumper pins together (number #2, #3 & #4 counts). Vmem should be about 2.9V and that is pretty much optimum for P4B. Memory clock buffer doesn't like extra voltage and I got best results with 2.8V Vmem (167Mhz stable, 1.8A). Vmem higher than 2.8V did decrease overclockability and caused buffer latch ups at high fsb's.

Niko, did it work?

Jarmo, aren't there four pins? Would this mod work for P4B266-C? Basically all I'd have to do is put another jumper on DDR voltage pins to accompany one that's already there so all four pins are covered?

Pin #1 in not connected to anything. You have to connect all pins (2,3&4) together. Easy way to connect 3 pins together is to take 3 pin connector with some wires from old cooling fan and join all 3 wires together. Then just put this over pins 2,3&4.
This "should" work on all asus boards with those 4 pins.
