Please help!! CUV4X Question

[WolfAtWork]

Hey guys, I'm a little new to the whole forum scene, but I have a problem that needs an urgent answer!

I have an ASUS CUV4X (VIA 694 chipset). In the manuals it says the board supports 800MHz+ P3's.
I just bought a P3 866, and I haven't installed it yet out of fear of frying it.
The stepping levels from Intel indicate that this CPU is either a 1.65, 1.7 or 1.75V core, HOWEVER,
the lowest available core voltage setting in the BIOS is 2.0V
I THINK, to run the new 866 I'd use a 6.5X multiplier and 133 bus, BUT what the hell do I do about the core voltage?
Is this gonna burn up my new chip running the core at 2.0V?
Please advise ASAP

Thanks in advance fellas!

Have you contacted Asus tech support? You may need to update your BIOS depending on the revision of your board. I looked on the web site and only saw jumper settings up to the 800 Mhz processor. I would imagine that you may need an updated BIOS to support the lower voltage requirements of the later steppings of the coppermine processors. If you do elect to try it at 2.0 volts (which I would NOT recommend, those dang Intel processors are still too expensive) make sure you have good cooling and a good cpu temperature monitoring system in place. You could just try it to see if it posts and make note of the listed core voltage in the BIOS and see if it auto-detects the processor and properly sets the v-core voltage. IF it doesn't, you could probably just shut it down before it gets too hot and prevent any damage to the processor.
BTW, what is your current processor? IF it is an older Celeron, it may have defaulted to the 2.00 volt reading and needs to have CMOS reset to enable the lower voltage options. My MSI-6309 boards both ran 1.6 volts just fine. Even my Version 1 with the first BIOS and they are the same Via 694 chipset.

I've got the newest BIOS flash (1009).
Right now it's got an older Celeron 400 in it.
Would this be causing the VCORE settings to look funny?
I would assume the lowest the Celery's core'd at was 2.0V??

I may be wrong, since I am NOT an expert by any means, but I believe the motherboard supports both the older PPGA Celerons like your 400, as well as the newer coppermines (with the lower voltage requirements). I suggest that you make sure you have an adequate and properly installed heatsink and fan, and go ahead and try that new PIII. My bet is that it will auto detect the coppermine and properly set the voltage to the appropriate level. Make sure the hardware monitoring is enabled and keep an eye on the core temperature, but I am willing to wager (albeit a small sum) that your coppermine will plug right in. Let me know if it works, and you have my sincere apologies if it doesn't.

Edit - Just to be on the safe side, you may want to clear CMOS first, so the board will reset itself.

it will work; i had a cuv4x + 800eb, and it detected it at 1.65v no problems if you want to be careful; use good cooling, since it should take 2.0v anyway (for a short while, just enough time for you to check in bios)

Ok, so correct me if I'm wrong:
When I drop a chip in this board, the BIOS will autodetect the valid range of voltages for the current cpu?
So if I pull the celery out that's in there now and clear the CMOS, it should autodetect the Cu core and populate the voltage settings box with the correct range?

I just wanna make absolutely certain of this beforehand...

Thanks so much guys....

Not bad for my first-ever Intel chip eh? ;-)

That is my understanding, if you set the BIOS to auto in the clock speed, as well as v-core. Let us know if it worked. I am almost certain and it sounds like Akuma X is, too. Good Luck, I have to go to bed.

EDIT - 1.65, autodetected no problem. Set it up 6.5 X 133 (6.5 x 11? wft was I smokin?)

Retail chip and HSF at defaults 37 degrees Celcius.

Thanks a million guys!
Much appreciated!

eh.. no prob; at least it works fine o/c that mofo!! (time for sleep, zzzzzzzzzzz)
