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

[powellandy]

Hi

I have the following system:

Intel Core 2 Quad 9300 with Arctic Cooler Freezer 7 Pro
Asus P5K Premium (BIOS 0612) with stock cooling
2x2GB Corsair Dominator PC2-8500 DDR2 RAM with Dominator fan
Antec P182 case with 4xNoctua P12 fans

Current BIOS settings

FSB 440
Strap 333
(RAM effective 1057)
RAM 5-5-5-15 (subtimings on auto -3-52-6-3-3 I think) and 2N
Static disabled
Trans booster on enabled 3 (gived tRD of 6)

Volts - Core 1.2750 (with LLC enabled - gives 1.26 measured in Everest), FSB term 1.1, NB 1.25, SB 1.05, overcharge 0.7, PLL 1.5, DRAM 2.2, CPU GTL 0.61, NB GTL 0.67.
Both spectrums disabled.

System stable with OCCT RAM for 10h and Prime95 small FFT for 4h.

However when I try for 445 I have to increase NB to 1.55 (have tried inc FSB term instead but not stable), even if drop down RAM speed/relaxing timings or trans booster.

I note that some can get all the way to 475+ with NB at 1.25 so my questions are:

1) Is 1.55 NB safe with stock cooling in case as above (sys temp when stressing is about 45, thermistor from voltmeter on NB heatsink reads 49).
2) Is there anything else to tinker with to hit 450 (or higher) without increasing NB voltage.

Cheers,
Andy
