Does anyone have a P3 1G working (not OC'd) in an Abit BX6 rev 2 board ?

I am looking at the fairly small difference in price between an 800 Mhz P3 and a 1 gig. I have been told that the 800 Mhz P3 will run fine (not OC'd) at 100 FSB in the Abit BX6 rev 2 board.

Perhaps the 1 gig, if at 100 FSB on the MB will run ok. Or, also, is the 800/850 the last of the 100 Mhz CPUs ?

Thanks, JJ

You can get the 1GHZ in a 100MHZ cpu now..10x100..

 

[JJFlash]

mastertech01 - Thanks. I am curious if the 1 gig will work in the Abit BX6 rev 2. Any idea ?
JJ

 

[mastertech01]

If it was intended to run coppermine then a Bios update should be avaliable or will be ... but from what I have heard it will run at 10x regardless because it is clock locked.

Thought I'm certain that a PIII-800E will work on the BX6-R2 (it requires user defined settings to choose FSB and multiplier since it's beyond the officially supported PIII-700) I don't think the 1 gig will work.

From what I've read and understand of the board, it will not allow a chip with a multiplier beyond 9.5 X. A PIII-1000/100 would default to 10X and I suspect the boards bios will not accept the chip as being workable, even with user defined settings.

The PIII-1000/133 would probably work as long as your memory and Graphics card are able to handle the 133 memory speed and overclocked AGP bus.

I would love to be proven wrong but don't have a PIII-1000/100 to test.

 

[JJFlash]

KR, this is appreciated. What are the multipliers (the FSB would be 100Mhz) for the 800E ?

I take it that the BX6 rev 2 takes the settings quite comfortably, eh ?


JJ

PS
(That chip, the 800 Mhz, would presumably be quite fast enough. It would probably be indestinguishable from the 1 gig in practical application. Thanks for having brought this up so that I did not have to send back a 1 gig)

 

[jaygee]

Run a 850 @ 952 in a ABIT BX2 R2 with no problem. Wish I had a 1 GIG to test.
:disgust:

The 800e is a 100MHZ fsb device so it's all running defaults on the BX6r2. Unfortunately, ABIT did not include the identifier for PIII's above 700MHZ in the Bios so it doesn't autodetect correctly - User defined settings to 100MHZ FSB and the multiplier of 8 works great. Also see post above (and others) that report PIII-850e working equally well with user defined settings.

Like many others, I'm able to successfully overclock my cpu - in my case, at FSB = 117MHZ PCI /4 It's rock stable at 936 MHZ. The PCI bus is very slightly underclocked and AGP bus is slightly overclocked but these seem to have no ill effects.

If you're running PC100 memory you may be able to squeeze a slight increase by going to CAS3 and avoid the investment in new memory.

 

[JJFlash]

Thanks KR and jaygee, That BIOS identifier is the factor that I had not fully nailed down.
So I see that FSB = 117MHZ PCI /4 It's rock stable at 936 MHZ with an 800E.
And that an 850 @ 952 in a ABIT BX2 R2 is no problem.

I would personally prefer not to OC, after much grief in the area, as that is the reason that I have returned my OC'd P2 333 back to 333 - previously in Win98 it was OCd (with a pelrier) to 500 but in Win2k it caused continuous booting problems. The 66 Mhz of the P 333 is too low.

So... An 850E would have the 100 MHZ setting and WHAT multiplier ?
Likewise for an 800 and 900, do you know what the multipliers would be ?

Thanks,

JJ

PS - ALso, I thought of getting the FCPGA version with an Abit SlotKET Converter, so as to have future flexibility. Do you know of any reason the Abit SlotKET might cause seating or component crowding in the case or any such difficulty that I might not now be aware of ?

All of the PIII-XXXe chips (note the E) are 100MHZ FSB. It's a straight 100 MHZ X multiplier for the operating frequency. An 800E has an 8X multiplier, 850(E) is 8.5X and the 900(E) uses 9X the FSB for a grand total of 900MHZ. The multiplier on Intel processors is locked so your motherboard will need to be set to match the correct multiplier of your device.

With the limit on allowable multiplier being 9.5X on the latest Bios version of the BX6R2, these will work. Again, you MUST use the user defined set-up for correct operation since the bios DOES NOT automatically set-up for PIII at higher than PIII-700E. (Me thinks ABIT wants to sell us all newer boards).

I'm using an IWILL SlocketII with an FCPGA version of the Coppermine PIII-800E. Slot one devices are still available - similarly priced. The slocket you use must be of the newer type that supports Coppermine FCPGA devices. Early Celeron PPGA Slockets will not work.

 

[JJFlash]

Thanks, KR. I guess going for the 850E makes the most sense. On Pricewatch I don't even see a 900E Mhz listed, only a 930, which would not have the 100 Mhz requirement with the BX6 r2.

For a difference of $50 it makes sense to go with the 850E rather than the 700E, and thus provide for a longer period of time before upgrading again.

I am now determining if I would often have to go into the BIOS to reinstitute the non standard (850E) bios setting/multiple and ensure Win2K would accept it, but I expect it should be fine at 850. Or do you know of a need to constantly re-set (upon re-booting) a setting which is not referenced in the BIOS ?

Thanks,
JJ

Uh, you save the bios, why would you need to reset it? Also to figure out the muliplier for a given bus speed why don't you just divide? 850 divided by 100 is 8.5

It's pretty funny that you mention all of this. I am also in the same boat currently sitting on a BX6 r2 with a 300 PII. I am planning on buying a new MB and Athlon 1ghz, but not sure what to do with with BX6. I plan on building a seperate linux box with the BX6 but not sure what chip would be best. I would also through in an old AGP riva 128, and soundblaster. Like I said, nothing fancy, just something I can play around with as a server with mail and web capabilities.

Any suggestions? I am leaning towards the 700e since I might want to overclock it, and it'll still work fine at 700 mhz with the 100mhz FSB. Oh well, as always, I love to hear the comments. Thanks

Turbopit,
The experiences I had had, the details of which I will spare you, of difficulty in booting into Win2K, are why I am a touch interested in whether I might have like difficulties with a CPU speed which is not referenced, as such, in the BIOS.

I could always do just fine in Win98, with my P2 333 OCd to 500, but it was after countless hours that I found, rather by accident, that Win2k would simply not easily accept the OCd P2 333. I know an OS should be quite distinct from a hardware factor, and thus I do not detail it to any degree.

And this is why I took pause at exceeding the 700 Mhz "limit" that is written into the BIOS of the BX6 r2. In any event, I expect that the 850 will "hold" in my system and if not, I can return it for a 700E.

Thus the further explanation, above.

------------------------------------------

It would be more helpful to explain fundamentals to Flash.

CPU speed = multiplier X FSB bus speed. If you know 2 of the three variables, you can figure out the other.

Don't be intimidated by the bios, master it. It's important to understand all the settings. Study this site and bios guide.

OK, I guess I wasn't clear on the "user defined" settings in the bios.

When you set the user defined settings for the PIII 800, 850 or 900 you save it as usual. It's stored in the CMOS. You do NOT need to set it each time you boot. The bios does recognize a PIII but does not autoconfig. for PIII's with multipliers above 7. The PIII-800, 850 and 900 (yes, there is a 900) use multipliers of 8, 8.5 and 9 respectively and work in a BX6R2 if you set the Multiplier, FSB, and PCI divider manually.

After you set bios for you CPU, save it and it works like a champ - cold boot, hot boot and every boot in-between.

I've seen occasional write-ups of overclocked systems not running Windows2K. I suspect that the problems are due more to instability in an overclocked system than anything else. W2K is a bit more efficient than W98 and probably exercises the system to a greater extent thus, any latent instabilities that were not evident in w98 become show-stoppers in W2K. In other words - the occasional hangs and blue screens you see in Windows98 are the instabilities that totally hang up Windows2000.

I've found that the PIII (even overclocked) is dramatically more stable than the C300A @ 450 was.

I don't know the exact specs of your board, but I am told that the 1000/100's do work in Intel-made BX-2 boards put in the Dell Dimension XPS Txxxr series -- the BIOS displays the chip speed as 000 but boots up and works just fine.

 

[KR]

Bachlaw-

What you say may be true however, the board in question and in discussion is manufactured by ABIT and the board model is the BX6 revision 2. Abit received a lot of good press in the overclocking community with this and the BH6 model motherboards being among the first overclocking friendly and reasonably stable motherboards. At present the ABIT BX6rev2 bios release does not support multipliers above 9.5X. The BX6 does use the 440BX chipset from Intel but the simalarity stops there.

 

[UltraWide]

multiplier that does not exists is overwritten by CPU microde to make it exist.
so yes in theory a 1000mhz cpu will work just fine in any motherboard that supports the required voltage for the fcpga Pentium 3.

PIII 600e set manually in bios to 6x133. Bios says at boot its a PIII 800eb. The latest bios (QR?) should identify the 800's, not sure of the 1giger though.
