Any particular tricks for oc'ing on slot 1?
I have an Abit BH6 V1.01 and PII 333MHz but cannot get higher than 112 fsb because the pci clock runs too high due to only having a 1/3 pci divider. Can the 1/4 divider be enabled via bios mod or is it hardware related (eg. clock generator)?
I also did a pin mod to the cpu in order to set the stock voltage to 2.6V to maybe get the core a bit higher (can now select anything from 2.0V to 3.0V in the bios). Is there a way to increase volts to the cache for better oc'ing as well?

AGP divider is a hardware limitation.
I know of no way to adjust cache voltage on slot 1. It may be possible, but I doubt it because I've seen nobody else do it.

Ah I thought so, guess I'll be looking for a BE6-II or some other later rev. Abit board.  I did take a closer look at it, and it does seem like it's possible to alter the cache voltage using an external buck converter. It would just take a lot of time and effort in order to do so. I might try it in the future since I only have one cpu & board right now and I'd rather not kill either. |

I think PCI clock is not matter, cache chips are more important than CPU core, usually limit of the cache chip clock comes first in Pentium2, try disabled 2nd cache in bios, you can see purely the limits of the core frequency. |

Yeah, cache seems to be the main problem so far, it will only do 200MHz whereas the core does around 450MHz(112x4) @ 2.3V by itself. The second problem is that I can't do higher than 112 fsb due to the IDE controllers or my hdd giving out at around 41MHz PCI.
The memory I'm using can do at least 155MHz 2-2-2 so that is definitely not the problem.

It's not the IDE controller, it's the type of HDD. Seagate and Quantum are much more forgiving with the high PCI frequency.  |

Okay, any drive in particular that I should look out for or will any Quantum or Seagate drive work alright?

I like the smaller drives, 40 gig or less, but I have the same success on the 80 gig drives also. I prefer Seagates. I'm good to around 48MHz or so usually.

Ah, I dug around through a box full of old hdd's and found a Seagate Medalist 2GB drive, small but should be okay to install win xp on. Need to see if it works though since it's 19 years old.  Edit: Drive works, installing xp now. Ugh UDMA 33  so slow. |

Seagate drive is no good, bad sectors. I'll go and buy a new one.
Ended up killing my PII 333 because of a screwdriver slip when trying to get the metal spring clips off. It's repairable but maybe not worth the time.
I did get a PIII 600E in the mail though (which is why I was taking the heatsink off the PII).

Are you in the US?

Close enough. I have quite a few extra Slot 1's if you're interested. I also have easier heatsinks to use than those spring clip deals. You could have them for cost of shipping.

That would be awesome, thank you.  Send me a PM. |

I will PM you a list of SL's a little later. You can choose what you'd like. |

so slow.
Send me a PM.
