Slot 1 PIII800 or socket PIII800 with adapter board?

I am looking at upgrading a slot one BXMaster motherboard to a coppermine PIII800. I have the MSI adapter board for the socket version. They make it in a slot 1 version too. Any advantages or disadvantages of one of the other?

Eug,

Funny you directed me to that post. I have another computer which has an early P2B board in it. Thinking I couldn't run coppermines in it I got a PIII600 non coppermine slot 1 which will go into the P2B when I get a coppermine for the MSI Bxmaster. I wanted to speed up both computers so I got the PIII/600 and am running it in the bxmaster until I get a coppermine for it. Then it goes to the P2b which I thought would be the fastest I could do in the P2B. That's cause I thought it was a bios issue with the P2B not supporting Coppermine chips. From the referred post I take it that's it's a voltage problem that can be corrected by using a socket to slot1 adapter.

It IS a BIOS issue, but that can corrected with a simple flash update. The main problem is the voltage issue.

Check my sig. I have a Coppermine Celeron running right now at 880 MHz (8X multiplier at 110 MHz), on a P2B revision 1.10 with BIOS 1012 (updated from 1004).

All 1.12 P2B boards support Coppermine. Boards back to 1.02 also support Coppermine, but with some caveats, with voltage in the early boards being the most problematic. These will not always go under 1.8 V, and the newer ones do it kind of strangely, so Asus just states it doesn't work. However, if you update to the latest BIOS, essentially all of these work at 1.8 V and up for sure, and some will work at lower voltages too. My 1.10 works properly at lower voltages that are multiples of 0.1 (tested down to 1.5 V), but I run 1.8 V simply because I need it to hit 880 MHz. (I can do 800 MHz at 1.7 V though.)

Note that the slocket does not correct the problem. If your board does not support 1.7 V and you set the slocket to 1.7 V, it simply won't boot. The benefit of having the slocket is that it allows you to set the "wrong" higher voltage of 1.8.

What version of the P2B do you have?

Don't know the version of the mother board right now. Have to look after I get home.

Edit: Version is 1.02 and the manual says it goes down to 1.5 volts.
