[18th Anniversary] Asus Black Pearl - P5k-Premium Testing Report

[ladderman]

I want to tweak my voltages so I can try to gradually move up to a 9 x400 FSB

The two settings I would like some advice on is the CPU PLL Voltage and the FSB Termination Voltage.

What are the safe max volts for these two settings?

Is the CPU PLL Voltage just beneficial to quad core CPU’s?

To get a stable 9x370 FSB I’ve moved my CPU Voltage to 1.43750v, CPU PLL Voltage to1.50v, and my FSB Termination Voltage 1.30v.

Idle Temp is 24c, and under full load 45c

This link http://www.anandtech.com/cpuchipsets...spx?i=3156&p=4 for Asus P5E3 BIOS tweaking gives a detailed explanation of what ithe BIOS settings are for. Most are the same/similar to this BIOS - ignore the non relavant ones.

For now Change PLL to auto and leave FSB =1.3. Your temps look very nice - my E6600 idled on 46c-48c on air at 3.6 with 1.5v!. Jump in and try going straight to 3.6 with 1.475v - 1.5v vcore 9*400. If stable reduce vcore incrementaly downward until you find lowest stable vcore. The E6600 nearly always needed somewhere between 1.45-1.5v for 3.6 stable.
You are safer running DDR2 memory at 2T until you are stable - once prime stable you can play with command rate if you want.

Yet another great link.

I'll do as you advise, and post results tomorrow.

many thanks
