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

[jonny_ftm]

Hi

Have tried. Still have OC failure at boot (same as jonny_ftm describes earlier) despite system being stable for hours with Prime95/OCCT. Have new BIOS skew options - tried changing from auto to CPU -300 / NB -100 and system became wouldn't post - so put back to auto until someone figures out whats good.

No other real difference noted.

Regards,
Andy

In my case, it was sorted by adjusting NB et RAM voltages. I no longer have those issues now.

Interestingly, I found a way to trigger that boot hang up when my OC is unstable. If I decrease NB or RAM volts, when I try to enter the bios, it hangs up, a reset is needed, than I can boot without even an OC error message sometimes. As soon as I adjust NB and RAM voltages, I'm again rock stable at boot/bios load.

Guess, every system has its specifics The most important to consider, is that it's hard to 100% be sure ofan OC, it needs time...

Thanks. The only way I got mine stabe (despite inc NB volts and DRAM volts) was to change strap to 333 and hence DRAM speed from 1103 to 1057 - memory rated at 1066. Seems to be OK now on specs about 5 posts above.

I am interested in your thoughts on NB voltage. I can get to 440 FSB with 1.4 but any higher needs 1.55. I notice you get 475 at 1.25 but use aftermarket coolers - is there any voltage you would tweak to allow 450+ at 1.4 (I have tried most with no success).

Cheers

If I believe most what was said here and some other forums about the P5K, most boards will do +450 on lowest or 1.40v for the NB. Many others will need much more. Could depend on your particular setup (memory speed/timings, number of modules...) or the just the NB batch. Remember, the NB is like a CPU, some batches do overclock well, some others not. There are also often hidden revisions of the NB chipsets that intel often hides claiming them: minor or not to be considered bugs. The P965 was a an example...

Finally, motherboard manufactures often make hidden PCB revisions enhancing the overclock or fixing the bugs. The P5K premium is another good example with the SATA bug

Manufactures no longer note the boards/chips revisions just to be able to sell all their old stocks.

set CPU skew and NB skew AUTO,you'll increase CPU FSB without too much voltage
