Abit BH6 Rev 1.0 & CuMInes

[beebernitz]

Anybody out there have a Rev. 1.0 BH6 working with a 700MHZ PIII Coppermine? I have a Soyo 6BA+4 with the 700 PIII and would like to upgrade to a 850 and drop the 700 into the BH6.
Just want to be sure I dont destroy the 700 or the BH6.

Thanks

It will run but:

To choose a CPU like P-III ?700 to run 133FSB on BH6 is not a good idea, since the BH6 has only 1/3 divider to the pci. Which means that pci components (like HD) can have trouble running at 44Mhz pci (33MHz is the normal).

The newer BX boards have ¼ divider for 133FSB so it is not a problem.

However if you don't o/c or o/c to 112MHz FSB there is no problem.

JackMDS thats not true. I also have the 1.0 BH^ and it has 1/1 divider and the 2/3 divider. Nothing with thw 1/3. I was also wondering if I would be able to use it. I heard get the Slotket 3 that lets you run the 133mhz without a problem?!?! Can someone elaborate on that? Thanks in advance.

p.s. Isn't the p3 700 a 100mhz based?

Jack is talking about the PCI divider. The 1/1 and 2/3 divider you're talking about is the AGP divider. If you have a decent AGP video card, it should be able to handle the 2/3 of 133MHz, which is around 89MHz. Voodoo3s, GeForces and G400s are known to be pretty tolerant to high AGP bus speeds. I don't know about other cards.

However, PCI cards, due to their variety, can fail if the bus speed is too much above the specified 33MHz. Then again, some versions, if not all versions, of the BH6 have a 1/4 divider at 133MHz FSB, or so I read. I personally have a BH6 1.0x, but I've never tried anything more than 112MHz FSB so I can't verify that.

Yes the P3-700 is 100mhz based, what I want to know is will the BH6 (rev 1.0)be okay with a 700 mhz coppermine? The pci and hard drive have nothing to worry about as I will run it @ 100mhz, no stress there. This is a secc 2 based package so no slotkets apply.

Tell me if you ever find out it works. ?I was wondering myself.

Thanks

beebernitz, sorry I didn't answer your original question in my previous post. Anyway, here's your answer...

Although the Abit website doesn't state compatibility beyond P3-600+s for either versions of the BH6, I've read about people on this board who have successfully run a P3-700 on an Abit BH6. It would probably be recommended, if not totally neccessary, to upgrade to the latest BIOS revision. For rev 1.0, that would be version SS. I'm currently running a C566 at 850MHz on a BH6 rev 1.0x with version SS. Version SS seems a lot better than version QN that it replaced.

beebernitz, I've been following a thread in the Abit newsgroup re a guy running a P!!!-800 on a BH6 rev1.0x w/ no problems. I don't recall if it's an FC-PGA or SECC2.

FWIW I've been running an FC-PGA P!!!-650 for six weeks w/o a hiccup. And, this is on a rev1.02 board w/ the 45N03 MOS-FET chips which isn't supposed to run the CuMines well. The P!!! is on an Abit Slotket!!! and a Thermaltake Golden Orb HSF.
