Celeron 300A@450 -> 700@???

[OldOverclocker]

Help! Have a BH6 Rev 1.0 (BIOS SS) with retail HSF Celeron 300A, no troubles at 450.

Swap a Celeron 700 cC0 SL4P8 with GORB and ASUS S370DL (had to remove the plastic hooks to fit the MB) and best I can do is 875 (83 FSB). Next step is 100 FSB, but won't even post at any voltage (1.7 - 1.9). Should I flash with higher voltage?

Swapping CPU corrupted win2k sp1. Reinstalled over existing, and now CPU utilitization often hits 100% utilization for a couple seconds. Might need to defrag MFT. What am I doing wrong?

128MB CAS 3 PC100 RAM, RivaTNT video.

get a better cooler, that gorb is not going to cool the 700 well enough.

Probably inadequate cooling. Maybe you need to reformat the harddrive and do a fresh Windows install. It's happened to me before after registry corruptions.. Some of those Celly 700's were not the best overclockers either.

my chip did no better at first... so BURN IT IN. and i am shouting over a delta 38 on an alpha heatsink. your motherboard should have monitoring for temp checking though, but if temps are high an alpha will knock 8-10 degrees off

Flashed the BIOS a couple times and brought VCORE up to 2.2 (!) Still wouldn't post at 100 MHz FSB. Dropped VCORE back to 1.7V at 83MHz FSB.

GORB looks ok. Temp only 30C.

I'll try to burn it in a while -- at what setting?

I'm a bit cautious with my cele700 but my patience has been rewarded. I do not know whether I just have a good chip or if it was my method (or both).

What I did:

- I let the system burn in for about 2 weeks at default speed and voltage ( I run genome@home ) while I learned more about OCing and waited for some parts. This is at default 66MHz FSB.

- I bumped the system up to 70MHz FSB and was stable in win2k. I let this go for several days.

- I bumped again to 75MHz FSB and let it go again for several days.

- Finally I bumped to 80MHz FSB and ran for about a week and a half. Still stable in win2k and still at default voltage.

Inbetween some of these, I briefly dropped back to standard speed while I did system updates (win2k sp1, dx8a, etc.).

My last bump was several days ago to 90MHz FSB. Still stable and at default voltage. I did briefly (several hours) raise it to 95MHz FSB but I am not able to handle the temps at this level until my care package from PCNut arrives. This is also with the stock (but lapped) cele HSF. I have been rewarded with slow small steps. YMMV 8-)

Ok. Clean install of win2k and the 100% CPU utilization problems went away.

Burned in 1.7V@700MHz and 1.8V@875MHz for 3 days each running Sandra. Temp was 24-29C (room temp was 20C).

Still wouldn't post at 100 MHz. Since 100 MHz is ok with my 300A, I figure its the 700 (or Asus slotkey). Disabled L1 and L2 and still no luck.

Does the plastic hooks on the slotkey do anything? I had to rotate them 180 deg for them to clear the board mount.

Either that or I'm just not lucky with the 700.

If ya can. I'd suggest trying an MSI-6905 Master ver2 slotket. Seems I've seen another thread or two where the prob was the slotket with that mobo.

isn't it suppose to be like 1050 mhz at 100fsb. I know alot of celerons don't like going this far without extreeme cooling. one of my friends has his celeron 600 at 900 but he can't get it to go much farther stable. a better heatsink would help you out but 1050 is still a big number to hit.
