Was troubleshooting my win98 system as it was showing signs of lagging in some games. Before blaming the voodoo 3
as the culprit tried out a number of cpu's to rule out that variable. Out of curiosity snapped in the PIII 850 and it shows
up at boot as 700mhz. which surprised me, thought the max. for this board was a 450 PIII. Some benchmarking with 850
PIII yielded the following:

3Dmark2000 - 3100
Unreal - 66fps
GLQuake - 111fps
Forsaken - 78fps

All were done with 800 x 600 16bit. Based on some of Phil's videos my system is definitely slow so maybe next step is
swapping out video cards. Before all this I was having trouble running the plane game Fighter Squadron SDOE with it
"black screen" crashing several times under 3dfx mode. Think I may reinstall windows and see if that improves things
before changing the cards. What do you all think? Is the performance on par?

Asus P5N-E Intel Core 2 Duo 3.33ghz. 4GB DDR2 Geforce 470 1GB SB X-Fi Titanium 650W XP SP3

What is the board revision and the bios version?
I have two Seattle boards, one is OEM Intel and the other is in my Dell XPS, they both support my PIII 850 without a problem.
I'm not sure on the Dell but I'm fairly sure that the BIOS version on the OEM is P13.

I'll have to get back with you on the bios. I always thought the se440bx-2 was the board that supported the
higher end slot one cpu's.

Hmmmm.
You might be right, I will have to check mine. Seems like you might be right.
I know my Intel branded one supports pretty much all of my Coppermine chips as well as my Via C3 Nehemiah with the proper slocket.
I've had both a 1GHZ PII and a 1.1GHZ Celeron in there, i've tried them all on in the Dell though.

From what gather the latest bios for this board is P12 which is what I got. Now the cpu has a 100mhz FSB not 133 so maybe that's
why it's running no problem except the slower clock.

Have you checked the actual clocks peed in either DOS or Windows?
My Celeron 1100 shows up during post as a 'Pentium III 1000mhz' but is detected in Windows as the correct CPU with the correct clocks peed.
Likewise my VIA C3 shows up during post as a Pentium III 866, but again it's detected properly and runs at the correct clock speed.

Same here too, shows up at post 700mhz then in windows (cpuz app) it's listed as 850mhz. Regardless it's a nice surprise the board works
at all with that cpu.

Yes that seems to be the case for most people.
There are later BIOS versions for the BX-2 boards, but some tend put restrictions on "unsupported" CPUs.
My VIA chip wouldn't work with the p15 BIOS, but was fine with the p13.

Provided the correct voltage is provided, there is really no reason why they shouldn't support later Coppermine chips.
Of course that doesn't mean they all do.
