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

[Emperor]

hello gentlemen,

i've got my new p5K premium a while ago and i've some interesting issues which i require expert advice from u guys here.

abit of background story, the PCB comes with combo coloured caps and is Made in China (i HATE MiC stuffs) and the bios is 0204. I dont have a problem with my western digital drives (OS drive is a 2500JS while the rest are 5000AAKS).

Now to overclocking,

many times when i try to oc and try out settings to stabilize it and those settings that dont work often cause the board to get stuck in POST, simply refusing to boot. and I have unplug the power, plug back and press the switch again.

trying out different settings to make it post and boot is like shooting in the dark! i've no bearing as to what should i change to make it post and boot.


Now i am trying to overclock a set of Reapers PC6400 to run at 1050mhz but it keeps getting stuck in POST despite whatever i throw at it in the subtimings.
My settings are as follows.
CPU-6
FSB STRAP-333
FSB-525
PCI-E - 100
DRAM-1050
Command Rate 2T
5-7-7-17 (or 5-7-7-18)
tRRD - 4
tRFC - 42
tWR - 8
tWTR - 13
tRTP - 5
voltage 2.25v


i've tried tRRD = 8, tWR=10, tRTP = 3,5,6,8 but i still get stuck in POST.

Does changing to 0402 increase the stability of the overclocking?

How should i start relaxing timings from 5-5-5-15 onwards? 5-6-5-15?

this set of rams doesnt seem to like 2.35V, as there is a fair chance it wouldn't boot, BSOD or some form of instability.

thanks but..erm 4-4-4-12??

isnt it abit too tight for high mem freq?

For your RAM....yes.......unless your running over 2.2v

Have u had the CPU running with FSB over 500 before you started playing with your ram settings? quite a few have a 500FSB wall - like mine for instance.

thanks for the reply. I've managed to hit 520FSB so i dont think my wall is at 500 or at least not that near. I guess it's my rams.

so why not increase multiplier and lower FSB so the RAM run 1:1 slightly lower
with good tight timmings. It wont much difference in performance - a liitle bandwidth for speed.

yea but even so, I want to try clocking the fsb a little higher...

Ballistix 8500c5 or tracers clock like no tomorrow and they are now bargain basement cheap this week - http://www.overclockers.co.uk/showpr...odid=MY-093-CR Lovely micron D9s.
