Hi mate,
you updated your
CPU then ?
Your ramn is the same , so you had that stable earlier just use the straps to keep it at the same approximate speed.
Use Small ffts on Prime to check your
cpu stability.
focus on :
CPU Vcore
CPU Termination
CPU PLL - You may at high clocks need to up this from stock , but Use sparingly.resort.
CPU Reference 1
CPU Reference 2
Vcore & Termination voltage(
VTT on other boards) are main tools.
CPU Reference 1&2 Are both used to improve stability. watch prime small ffts and adjust the failing core setting. +/- a notch and retest. CPUref 1= cores 0&2 CPUref 2 1&3
I've never had a 45nm Quad so can't provide detailed settings , sorry.
