celery wont go 100mhz... is it my slotket?

i just bought a celeron633 on my old bh6 mobo. its the old version with limited core frequencies. ive got it running up to 790mhz[83mhz].the next step is 950[100]. is that too far fetched? i think it is my slotket adaptor. when i use softfsb to turn it up to 950 the system hangs... i read over at a dutch forum that it might be my slotket. a guy there bought one from abit after he couldnt reach 100 on his cheap slotketand got 900mhz on his 600.

now my question is:
if i buy a new slotket adapter [i now have a cheap. non-brand one] from abit like the other person did is there a good chance that i will be able to reach the 950mhz mark stable? im quite happy as it is... perfectly stable. but if i can get another 160mhz outof this thing for 20 dollars or so i'll be at the computer-shop in no-time.

thanx guys
 
What voltage are you using? Try going up to 1.85V to see if that solves your stability problem. I have a 633 that goes to 950 at 1.75V.

 
I personally would not run 83 MHz. I'd actually rather run 75 MHz if I couldn't hit 100. That 41.5 MHz PCI bus is killer on drives.

Yamaha 4416E CD-RW - works but not reliably at 41.5 MHz
Maxtor DiamondMax Ultra (I think) 30 Gb 5400 rpm - trashed itself in a couple of hours at 38.3 MHz.
Quantum Fireball 10 Gb 5400 rpm - works, but crashed once, at 37.3 MHz.

As far as the Abit goes, it's not bad, but everyone (including myself) do better with the MSI MS-6905 Master slockets. Some of the generic ones seem to be utter crap however.
 
I also suggest adding some more voltage to that cpu. 1.9 should be the max limit you set, but 1.9 is dangerous. You can use it for about an hour or two for testing and some bragging rights but don't make 1.9 a regular thing.
 
The MSI or Iwill Slockets are generally thought to be the most stable and reliable. But it's still likely that it's the chip itself rather than the slocket that is holding you back. It's worth a shot though, given that slockets are fairly cheap and always come in handy anyhow 🙂

If you haven't done so already, bang the voltage up to see if that helps (to say around 1.8-1.9 volts max). Also, listen to what Eug says - running at 83Mhz FSB uses a 1/2 PCI divider. PCI devices are supposed to run at 33Mhz spec, so at that FSB you're running all your PCI devices (hard drive/sound card/NIC cards etc) at 41.5Mhz, and you could be asking to trouble. I've heard of plenty of 'dead' hard disks as a result of running the PCI too far off spec. Be warned..


Good luck getting 950 out of this baby though 🙂
 
thanks guys. about that 83mhz... thats also my main concern. i dont really care about that 950. i just want it at 100mhz because it will be better with my hd and vidcard. so... ill be trying to get an msi or iwill.. but does anyone have experience with one from abit? ive got an abit mobo.. ant wont it be best to put in an abit slotket?

 
the shop only had abits... well i bought one... and its running smoothly at950 with 1.80volts.
i had blue screens with 1.75 volts but that could have been my memory... i had it at cas2 now at cas3..
im gonna try setting it bach to 1.75 now.
THANKS FOR ALL YOUR REPLYS!!!!!!!
without you i wouldnt have bought one of these things...... 🙂

me verry happy!
 
That's great 🙂 I was thinking that it could have just been that you had a bad chip, but you can't trust those pesky no-name slockets 😉 Nice going 🙂 BTW - 1.80 volts should be fine.
 
Heheh, great! 😀

Do I smell 979 MHz at 1.85??? 😉 I was able to crack OGR for an entire day before my first blue screen at 960 MHz 1.9 V... and this was with a lowly Celeron 533A - 80% overclock! 🙂

P.S. I must say though, the number of 633 chips hitting 950 is more than I originally expected. I wonder what CompuWiz gets.
