Question about failing to POST

[Tithulta]

I've been increasing my OC and currently I'm at 138FSB my next jump is to 150. When I tried I just got the blank black screen with no POST. Can this be due to the 735 chipset getting to hot? I'm only guessing there are 15 other reason that can cause this, but just wondering since I can pop of the heatsink and slap some AS2 on it and either replace the heatsink or remove it for a blorb.

Currently I'm running 43c full load so I don't think it's a cpu heat problem. Might be that the cpu just wont go that high. Just looking for suggestions from those of you with much mroe overclocking experience. The system in question is the top one in my signature.

138 to 150 is a fairly large jump. I'd sugest one Mhz increments if your bois will allow it.

As to the no POST, it's probably due to the Vcore. The higher the FSB, the more voltage the cpu will take. It could be that there's not enough power going through to POST. I'd suggest upping the FSB in one Mhz increments until you find where you're stable, then trying to increase the Vcore little by little. The slower you go with your O/C, the less chance you'll have of killing your equipment.

Like fearless said, thats a 112fsb jump. Try adding more of a vcore to the chip like 1.85. Since you state you have good cooling :D

But other than that I maybe stumpted or something.

i guess I'm as good as I'll get for now...K7S5A doesn't have O/C features we love...plus I don't want to pull my dragonorb3(aka core crusher) again so soon after doing the L7 trick. Maybe once I purchase some AS3...plan to build my nephew a system this spring and I'll think about a board with better O/C ability(for myself and give him my spare k7s5a) I'll prbably live with the FSB adjustments I have.

At this point I'm too happy with my systems to waste money for a few percent more performance. As at this point it's easier to just buy a faster cpu. Besides so long as the k7s5a supports the latest cpu why upgrade? If the later cpu's change format etc etc and socket A is no longer compatible, then I haven't wasted cash on a newer board when it could ahve instead been put forward for a compatible board.
