O/C Celly 700

[Digi]

Can anyone tell me a good core voltage to burn this chip in apart from the 1.70,Chips only 4 days old and will boot to 850 and is stable tried 874 boots but get windows protection error,wanna try and get as much out of it as i can,by the way can anyone tell me how to work out the cpu temp my mobo is the BH6 rev1.1 latest bios version the board only tells me SYS Temp which is 31 at full load is that good or bad.

Celeron 700 FPO*Q111A290
prod code SL4P2

is this a good overclocker.

Thanks Digi

I would say that at such as low speed it isn't the cpu holding you back but more likely the pci bus speed. 874mhz is on an 83mhz fsb which gives a 41mhz pci bus, this is just too much for some pci components expecially hardrives, it could also be a pci nic, pci sound card, pci scsi device or anything.
To test if it is the harddrive you will need to set the harddrive to a pio mode. to do this in the bios under integrated peripherals look for an option along the lines of 'primar master pio mode' it is probabally on auto, try setting this to mode 2 to start with. If the system now works at that overclocked speed then it is your hardrive holding you back, if it doesn't then keep at that pio mode and try removing any pci cards to see if they make a differance.
What vid card do you have?

thanks for the reply

Hercules Prophet 2 geforce mx 64 meg
soundblaster pci 128
netgear F311 nic card
adeptec scsi
seagate 8.6 hd.

all these O/C no probs with my p3 450 at 600 133 fsb
do you think these are OK or should i change also branded pc100 sdram 100 cas2

thanks Digi.

[Phil]

you listed many possible culprits there, and the fact that you can get 133mhz fsb with a differant cpu means the ram and vid card are fine as this puts the pci bus speed at the correct speed.
the soundblaster, nic, scsi and hardrive are the possible culprits though, obviously to boot to windows you need the harddrive so try taking the sound card and nic out, if it works fine try them one at a time to see which one stops you overclocking, if it still has problems then it is either the scsi card or disk.
what fsb options do you have available as if you can get over 92mhz this usually puts the dividers down a level so that they aren't over spec.

thanks again phil have virtually all FSB`s up to 155 on my board but under 100 all of them are in steps of 3 or 5.

you havent said which cooler you are using, this is a big factor and case cooling is nessary

[Digi]

juat the standard H/S Fan combo from intel retail box,what type should i be looking at.

Digi.

[Phil]

I wouldn't think cpu cooling is to blaim here due to the low cpu speed he's at. Something not liking the high bus speed seems to be to blame.
From looking at your list of pci components the 2 that stand out at the nic and scsi card as these are notourious for it.

[Digi]

Thanks again Phil will try taking them out at the first oppurtunity and see how i go on.thanks again

the celery 700 has a FSB mutliplier of 10.5 (DAMN THATS HIGH) and 875 is the MAX you are going to get out of it! which really blows and as mentoned before, it will throw ur PCI bus out of sync
it threw my USB bus out of sync, even after i set it back to normal! so my advice: dont push it to its max
