Will a PIII 1000mhz work in an Abit BX6r2?

I'm considering buying a PIII 1000mhz slot 1 processor to replace the aging PII 400 in my Abit BX6r2. Does anyone know offhand if the motherboard supports this processor? It runs at 10 multiplier X 100mhz bus. I'm not at home now so I can't check myself. Anyone know? Thanks!!! I'm not sure how high the multiplier can be set....

Multiplier does not matter, the cpu is locked. You have to define it in the bios though and disable error hold. It will work. If your video card is capable running a chip at 133MHz is better, the 1000E will not do this (well not that I have heard of). You are better off with a 700E or 750E at 933 and 997 MHz respectively. The 933MHz from a 700E is almost a given, the 750E is alot harder to get...

Even intel had problems nearing 1.13GHz.

Thanks for the replies:) My video card is a Voodoo3 2000 AGP, I've had my system at 124mhz bus 2/3 with no problems on the PII 400. Hmm, so you guys think I should go for the 750mhz? I wasn't taking overclocking into consideration; I just wasn't sure if the bios would let me set the multiplier for 10 which the 1000mhz cpu requires.

Yes you can run the 1000E on your board. If your looking to overclock then you might be better off witha 800E as long as your peripherals can handle off spec bus speeds. If you peripherals can handle out of spec speeds and your not looking to overclock then you might want to consider the 1000EB, which would be a bit faster than the 1000E due to the faster bus speed.
Otherwise the 1000E is a fine choice and leaves all your buses running in spec.

I have the same mobo with a 700E on an Iwill slotket. Running 966 (138fsb) @ 1.75volts.

If your choosing between the 700 and the 750, get the 700. Or if you got the money, might as well get the 1000E.

But I am pretty sure my chip will run higher, but I don't think the mobo likes anything higher than the 138 fsb.

The P3-1ghz (100fsb) should work just fine. If you want to save money, and tempt your fate that the rest of your system will be happy at 133fsb... Buy a guaranteed overclocked 700e from Compuwiz1 or Bonkers in the For Sale/Trade forum.

I just found a PIII 850 slot 1, 100mhz fsb for $220. I'm thinking of trying out this badboy. Overclocking isn't a real big deal for me. If I could run it at 8.5 X 112fsb which would be 952 I'd be satisfied. What do you guys think of the 850?

I'm trying to stay away from the 133fsb cpu's since they tend to be near their max off the shelf.

The 850 @ 952 sounds pretty good. Here are a few numbers to chew on:

The PIIIe 1000
FSB = 100
PCI = 33
AGP = 66
Everything is in spec

PIII 700e @ 933
FSB = 133
PCI = 33
AGP = 89
All in spec except for AGP which is quite a bit out

PIII 850e @ 952
FSB = 112
PCI = 37
AGP = 75
PCI and AGP are a little bit out, but not bad at all.

The PIII @ 933 would be the fastest because of the 133 FSB. If the video card can handle 89 AGP (most can) this is also a good setup. If you were to go this route, I'd highly recommend a guaranteed chip.

Sorry to but in here, but I have a similar dilemma.

Have an old Elite Group P6BXT-A Mobo, Intel 810 chipset. Max FSB is 100MHz. Multiplier in bios only goes upto 8 on "Manual" setting. On "Auto" the thing only goes upto a 533Mhz chip, no option to play with multiplier in "Auto" configuration.

Can I go for a P3 1000e, or will I be forced to max-out at 800MHz cos of the max "manual" multiplier setting? I've been told the board should just auto-detect the new CPU's speed and run at 1GHz, but I'm a little dubious about that...

Hell, I'm not even sure if my old Diamond Viper 8Mb Graphics card will run at 100FSB, may only be able to handle the slovenly 66MHz I'm running at now! (I have a Celeron 400 @ 450:eek:
