Hi all, I just purchased this board, it's still in transit. However, I do have some pictures from the seller though. Would someone be able to tell me what I'm looking for to work out if it's VRM 8.4 compliant? I plan on using a P3 850Mhz in it.
Of course

Thanks I'll have a look through that.

Thanks for that. I did find that thread first and was going to post to it but then I got a warning to say it's very old and I should create a new post. I couldn't find any info on their on how to identify the version. They talk about certain chips but I'm not sure exactly where I'm looking for them on the board.

I think that page may have answered my question. The problem is the picture taken is too blury to see the writting on the chip. I'll have to wait for the board to arrive. Thanks again for that link.

Q: How do I find out which voltage regulator chip I have and what voltages it can provide?
A: You need to look at the board. Near the Slot1 connector there is a chip with around 30 pins or so. Some of these chips can provide 1.3V-3.5V, while others can only provide 1.8V-3.5V. Attention, dual-cpu boards have two voltage regulator chips, and it is possible that one is of the new type and the other not!
Chips that can provide voltages down to 1.3V:
HIP6019BCB
HIP6020ACB
HIP6004CB
HIP6004BCB
US3007CWChips that can only provide voltages down to 1.8V:
HIP6019CB
HIP6004ACB

Probably ok to .dig. and old thread when your query directly relates to exactly the same thread topic ...anyhoo, from that old thread...
The 1.04 revision board is on the left -- area inside yellow boxes is VRM section --- you will note the capacitor layout on the 1.04 revision differs from that of the 1.03 revision (red circles) ~ this would suggest to me the 1.03 revision board you have is *not* VRM 8.4 design.

Actually, I had a closer look at it appears my board has the exact same capacitor configuration as the compatible Rev 1.03 (shown in the other post) so I might have a chance.
Would appear to be the case... on with the show! =)
Those boards will most likely all run with Coppermines up to 1.1GHz. Many still much older boards run with Coppermines too but when the VRM is not compliant with the later Coppermines you can run them on 1.8volt (which is only a slight overvoltage).
One aspect that could or should also be considered is powerdraw as mentioned by Deniz here:
Re: ASUS P3B-F Comparison v1.03, v1.04
The higher clocked Coppermines - say over 900MHz - draw more power than the earlier generations Pentium 3 and may in certain situations cause too much stress on the motherboard. The subject is discussed in this article about Tualatins:

Jackpot! Thank you to everyone for all the info. My Rev 1.03 has no issues with Coppermine's. Just shows you don't need a Rev 1.04 board. I got my Rev 1.03 at gamble for pretty cheap.
I ran 3dMark99 for 2 hours with zero issues.
