Anyone with at Abit BX6-rev2, I need Help

[RavenatUWM]

I have an interesting question. I have an Abit BX6-rev2 Mainboard, currently running a Katami P3-500. I was wanting to upgrade to around an 800. In the bios, there are soft multiplier options for 5, 5.5, 6, 6.5, 7, 7.5, and 8. So, I would assume that I could plunk a regular Slot one 800 in, but I read that they can only handle up to 700mhz CPU's.

I emailed Abit and they confirmed this, saying that:
"With the latest Bios update, the BX6 v2.0 should support the Pentium III processor at 700MHz only. Even though there is multiplier factor of 8x, the motherboard is offically supporting up to the PIII-700MHz.
Does anyone own one of these MB's & a P3-750/800? Can you confirm either way for me?

Thankyou!

it'll work...if the multiplier is there is will work
8x100fsb

i DO have an Abit BX6/2 but sorry i am using a 700E and cannot prove you correct

how ever it is an interesting question and i thought about it before
i overclocked my 700E to 868/124 on the mobo
this proves that the MOBO can supply voltage/amperes beyond 700MHz
so the only problem is the multiplier

but the multiplier shouldnt be a problem as it is locked by the CPU

as far as i know, intel didnt have serious modification (if any) going from 700MHz to 800MHz


it states the mobo is 'officially' supporting 700 - correct
BUT,
when i was using my C366 oced to 567/103 on the same mobo

it is also 'officially' only supporting 366, but i am running it at 567/103 stable

i think it should work for a 750/800E

I understand, however, what I am really looking for is someone that is running one of the "unsupported" cpu's (750, or 800) to prove me either way. Thanks for the help though.

I have one running a 550e 5.5x100 @ 733 and also one thats a 733EB using 133FSB Default and running that at 138, 5.5x138 = 759.. no problem either.

i have a P3 800 retail (paid 300$ for it) on a abit bx6-2 run great at default voltage.Have two hard drives,one 30 gig, one ten gig,250meg zip ide, cd rom 256 megs of ram, soundblaster live,100mb nic ,machine runs fine. You have to go to user setting & pick x8. it posts a p3 at 822 with turbo on tried it at 933 it would post 933 but wouldnt boot windows, didnt try to up the voltage, with turbo on it posts 822,it is very fast with the geforce 2 card

Thankyou, finally I got a responce I was looking for. Maybe I'll be buying that 800E soon. Else I am going to wait for a t-bird w/ddr.

IT WORKS

I was in the same quandry but took a chance and ordered a retail PIII 800/100FSM FC-PGA version and tried it with an IWILL Slocket II on my BX6 Rev2. CPU arrived last night, installed it with retail HSF on the slocket, set jumpers on slocket to FCPGA, voltage to default voltage (chip defined) and bus to chip's default bus speed (100 mhz).

Before removing my celeron I'd set the voltage to be Chip Default - so that the chip would select the correct 1.65 volts for the PIII when it was installed.

On first boot-up I went into the bios and set the speeds to user defined, 100 MHZ, X8, AGP 2/3, etc and the system came up as a PIII at 800 MHZ.

Turning on Turbo brought it up to 822 MHZ.

Since I'm using PC100, I only tried a mild overclock with FSB set to 112, memory timing set to 333 and bumped the voltage up to 1.7 (default is 1.65).

After 12 hours of initial running, it's stable at 898MHZ, with PC100 set to 333 timing and voltage at 1.7v (a minor bump).

I have an Orb ordered so as soon as it arrives I'll try for a higher fsb (hopefully my PC100 will make it to 124/125MHZ)and I may see the magic 998/1000 MHZ -

Stay tuned for further updates.

You shouldn't have any problem there, I have 2 sticks of PC100 ram, one micron stick, and one generick, both are stable at 124mhz @ 3-3-3. They will do 129mhz, but they become a bit iffy for stabillity. Good luck

Today's Report -

935MHZ Stable @ 1.7V, Retail HSF , PC100 @ 333, BX6r2

Thats the same speed i run mine at. I have a BX6-2 with a slot 1 PIII800 running on the 117/29 bus speed at 1.70v. It also works at the 124 bus speed with 1.75v but my GF2 doesn't like the high agp speed and gets a little bit of texture corruption so i just stick with 935.

I have a bx6-2 and want to upgrade to a P3-800. Do I need to get the FCPGA version P3-800 and an adapter, or can I use the Slot 1 version P3-800? Which would work better? Could someone list all the settings I would need for the CPU Menu in the bios? (voltage, multiplier, agp multiplier, etc.) I flashed the latest bios for the abit bx6-2. Thanks!

I'm running a 600mhz Celeron, which is a 9x multiplier. I'm overclocked at 900 (9x100) so i'm sure you can run an 800mhz chip.

Tony -

As i wrote above, the PIII 800E does work in a BX6R2. It isn't officially supported and is not automatically detected by the bios so you'll need to use the "user defined" speeds or 100MHZ for the clock and X8 for the multiplier. 2/3 AGP, and speed hold - disabled. If you just let the board detect the chip it sets the clock and multipliers to whatever the chip says but will keep telling you that the processor has been changed or som such message. The manual settings allow everything to work just fine.

I'm using an FCPGA since I may upgrade my mobo sometime in the future and it's becoming easier to find good mobos in the socket version than the slot 1 versions - and I expect this will continue. The MSI slocket gets the best reviews so either the MSI, the Abit or the Iwill III will work with your BX6R2 and a coppermine PIII - reports have been good for coppermine PIII's up to 850 MHZ.

I've been able to successfully o'clock my PIII-800 (CBO) to 992MHZ (124 X 8) at 1.85V on my BX6R2 and others are reporting similar success.
