Hi folks, in the coming weeks I'll be prepping my Abit bx133 motherboard for benching. I'm going to be pushing the board hard and OCing mostly celly's and early 3.3v GPUs. No sub zero but water for sure.
Does anyone have any advise on VRM mods, vdrop mods, NV voltage mods or anything else ? I'm guessing since its more or less an SK370 version of the be6-ii the same mods would apply for the bx133?

Shouldn't really need any. Things you WILL need though. PLL# for SetFSB Good SDR The SDR I sent you is good to 180 FSB  GL and good benching. |

nice, 180fsb would likely be more then I ever be pushing. I plain to stick mostly to 66mzh and 100fsb chips. But if I end up wanting to push 133fsb chips it will come in handy, assuming I can find a hdd/hdd controller that can take the higher clocks. I try messing with ISA hdd controllers or flash drives to get around that if I end up benching more 133fsb chips.

Small Seagate drives hold a big bus increase better than anything else. |

Never used one so no idea.

Never used one so no idea. Nor have I. I like the concept tho. It would cut down on clutter on the desk. Maybe some day I'll get one and test it. |

I think I remember you saying that before. what about those IDE DOM flash drive type thing that plug into the IDE port? IIRC, these require power lines on some pins that aren't present by default. It's mostly VIA embedded boards like EPIA and similar ones that have them powered hence making DOM work. And I'm not sure if they handle high PCI o/c good. But what I know is that IDE->SATA adapters do so I'd recommend one of these. Might be tricky to get an SSD recognized by BIOS though, not all of them work. But many do. GL! |

What about water cooling the NB? I have a block that I can add to the loop, but I could also add a fan to the chip set heat sink too.

Wow I did not know that about the DOM's. I'll try a sata adapter too. Anything I can do to to rise the FSB wall on the board will be useful when beaching 133fsb chips. 🙂 |

Anything I can do to to rise the FSB wall on the board will be useful when beaching 133fsb chips. 🙂 Nah, for 133 CPUs you definitely need the Abit ST6/ Asus CUSL2/TUSL2 boards as they can go over 200MHz. BX will limit at 185-200 tops. Also, with 3/4 and 2/3 FSB:DRAM the i815 should be faster than BX133. So the sweet spot for BX133 will be frequencies were you are not limited by chipset overclocking but at which i815 can't handle memory frequency higher than bus frequency (dividers higher than 1:1).
Well, I'm speaking of best of the best case scenario. You'll definitely need WBXtune as it can tweak two leadoff timings which no other utility can. Both give some improvement, AFAIR one a bit more, one a bit less. As for water cooling it's not too hot to be cooled that way. Unless we're speaking of cold water like below 10C, maybe worth a try then. And I would try to lap the chipset.

" lap the chipset"
Never thought of that. But yeah a 815 board would be better but I have the bx133 and no 815 board so its what I'll be using for now. I'm focusing on 66fsb cellys so the BX should be fine. I"ll look into getting WBXtune, sounds like a good app to try.
