This is where I'm at right now (this is the system I posted in the screwups thread as having a "missing" 512 DIMM after a gravity-assisted crash btw).

ASRock P4M800, Celeron D 330 2.66, 2x 512 DDR400 (2-2-2-5 I think).
CPU @ 2.94GHz, FSB @ 147MHz, RAM @ God knows what.
Cooling is provided by a ducted HSF and temps never go above 63 deg. celsius. Oh yeah, it crashes out and defaults at 148MHz...

I would like to make this system break 3GHz+ (150MHz+) without any changes to the hardware itself. Where it gets complex: the BIOS only allows me to muck about with the RAM timings (and is very obscure in what it calls them), RAM freq. and the CPU FSB itself - no voltages, nothing interesting. sigh. I've also got an odd RAM issue - it tells me I have the full 1GB, but only 'sees' one of the 2 512 DIMMs I've got in there. I'm thus hesitant to bugger about with the RAM more than necessary.

What I want to know - have I got it as far as it can go, am I missing something, can I get it further, or should I cut my losses and save my OCing for the 925 I'm looking at?

Thanks in advance...

What hd are you using sata, ide, sata2, this means lots second is the chipset 8237 A or R You will most likely have to get a sata2 drive or a sata2 controller with ncq and tcq capibilities

SATA1, 2x WD 80GB, VIA 8237R.

what are the diffs between the A and R revisions?

Update: tweaking over the weekend got me up to 149MHz FSB stable. Temps are starting to get a little overboard though. (2.98GHz @ 63 deg. idle)

Which 9xx series Pentium is a decent OCer?

Reply to mugz

sry for the delay the difference is the "'A" is sata2 compatiable where as the r is not and wont work with extreme ocing

Reply to gomerpile

Thanks.

damn.

found another few blockages. buses cannot be locked down, no voltage controls, among other things.

using a different board I can get the little sod up to 3.32 (166x20), not feasible due to it being someone else's...

p4 820,840,925,945

or better yet get a better mobo and see where it can then take you

Reply to tehrobzorz

yeah, OCing on that ____ ASRock board is akin to raping a porcupine without shaving it first. Actually, less pleasant. Problem is finding a better board (socket 478, aargh).

What the hell. I'm already 1/3 through designing a WC system for the thing, so may as well.

Who knows - right mobo and I could probably do 4GHz.

Reply to mugz

thats the term I could not remember locked and unlocked busses thanks
the one you need to find are 8phase type

Reply to gomerpile

did the 478 mobos come out with 8-phase?

Reply to mugz

I only remember a 6

Damn! I vill kill everyvon in ze vorld!
