ASRock P43DE3

post #1 of 3
Thread Starter 
OK - I bought this board last week as an open box item and after setting it up with my Pentium D 930, I started working with it to see what it may do.

Everything is working fine, no issues at all with temps and the like, seems to be great except in the OC'ing department.

This board will clock the chip to at least 4.1 on air but I have to use the OC'ing software to do it, if I try to do it through the BIOS, I can't get it to do anything much past 235MHz on the bus and it refuses to boot. It runs everything fine once OC'ed with the software but getting it there using the BIOS seems to be impossible.
I've noted the RAM I was originally using was part of the problem and I have a different set in now and it's doing better but no change in it being stubborn related to bus speeds.

I'm wondering if it has a quirk like my Asus board does - It needs the PCI bus raised to 118MHz to boot with anything over 220 on the bus. As to the capability of this chip, the screenie shows it can get there but only in the way I've mentioned.

Suggestions?

You could also have a FSB hole, which means that although the motherboard can't boot at 235MHz, it may boot just fine @250MHz. You could also try on the CPU a BSEL mod to raise the FSB directly to 266 while bypassing the BIOS (it's a hard mod on the CPU, but easily doable and not hard to remove in case you don't want it any more).

+1 rep for the suggestions.

I'll see if it does have a FSB hole working against it and also look into the mod just in case.
Thanks!
