Pentium 3 1000 at 100 fsb

I saw at sharky extreme's cpu price article this week that someone is selling a 1000 megahertz p3 that is slot 1 and runs at the 100fsb. Since I had never heard of this, I went to intels site and confirmed that they do have a processesor like this. I am wondering if it will run on the bx chipset. I have a msi 6163 pro. The bios only has a multiplier of 8 but since the ratio is automatically detected I thought it might work. I know a p3 850 is supposed to work. What I was not sure about was that somewhere I read that the bx chipset could not support a multiplier of more than 8.5. Does anyone know if this will work.
 
These are the original P3's that were considered vaporware, back in Febuary of 2000. At the time, they were nearly impossible to find, and remained so for many months. A BX board can support it, as the P3 chip itself overides the BIOS anyway.
 
What ticks me off is that my Asus P3v4x board only supports up to 733!! err!
Anybody able to overclock this board... or tried? (slot1)

Actually the original 1GHz P3's that were considered vaporware for so long were 133MHz FSB Slot1 parts in the cB0 stepping. The 100MHz FSB Pentium 3 @ 1GHz didnt become a reality until long after the 1GHz processor had become commonly available.

Assimilator1, there is a 900MHz P3 in FCPGA.
 
ah ,&amp; a 950??

You're wrong mate 🙂

Support Slot 1 Coppermine Pentium® III/II 300MHz~800+MHz or CeleronTM Processor (with ASUS® S370 Card Series)
Notice the 800+ 🙂
 
Grab the latest bios for your board.
My Abit BE6-II (440BX chip) has the 10X multiplier in the latest bios. Maybe MSI has something similar.

Intel never produced a 950MHz P3. Thnat just the only common speed grade between 450MHz and 1GHz that they havent introduced a P3 at.

I stand corrected!
 
You do not need to worry about how high your mutilplier goes on you MB. Intel locks them anyway. I have a celeron ship in a AsusP2B with a mutliplier of 9.5. My board only goes up to like 6. Also I have run my P3 1000 133 FSB chip in the same board before. My friend has his P3 1000 133FSB running on a MSI 6163 Pro. If your board can support coppermine it will support the P3 1000 either 100 or 133 FSB. I would get the 133 version of the P3 1000 and run that board at 133 to get better performance out of it. Also the newer 133 FSB 1000s tend to OC better.
 
XRaider,

I have a P3V4X, and am running my P3 1Ghz 100mhz. It detects the 10x multiplier fine. I am also using the 1006 BIOS.

I just bought a Micronics Helios dual slot 1 440bx motherboard. Think I could run dual pentium 3 1000 slot 1 chips in this?

Thanks

I am running on an ASUS BX board and I have always stayed with the 100MHz FSB processors because the BX chipset was not designed to run at 133 MHz so it does not have a divider to bring the FSB speed down to the proper amount for AGP and PCI cards. This means if you are doing a 33% overclock to your processor, you are performing a 33% overclock on your peripherals too. Some devices can hack that and some can't. Bottom line is if you don't know if all of your stuff can run overclocked by 33% and you buy a 133 MHz FSB you might not get the rated performance out of it because you will have to scale your FSB back to cater to the slowest peripheral. I would stick to the 100 MHz FSB processors so you know you will get AT LEAST their rated performance, then you can work on overclocking.
 
A very good point ,except that many BX boards have a 1/4 divider for the PCI bus ,my Soyo 6BA+III does for example (it's nearly 2 yrs old).AGP bus is still a problem though 🙁
