Pentium III 1Ghz

[bunker]

This is a bit OT, but I figured folks in here would get more of a kick out of it.

I've got an old Dell (BX motherboard) that I've been searching for a cheap 1Ghz slot 1 processor to upgrade (it's 600mhz now).

Front side bus on this thing is either 66 or 100.

The Auction

I'm interested, only problem is, I need a 100mhz fsb processor. Now the 133 fsb version of this chip is all over the place, the 100mhz chip is a bit rare. His description is pretty much useless so I email him a question:

Me: What's the front side bus on this processor? 100 or 133?

Him: You can set the front side bus on your motherboard to either 100 or 133 mhz and it should function correctly.

Me: No, my motherboard does not have a setting for a 133mhz front side bus. Many 100mhz boards do not. Is this a 100 or 133 processor?

I'm a bit peeved right now because he didn't answer my question, kinda side stepped it.

Him: It is compatible with the front side bus being at 100 mhz.

I'm about ready to say screw it, but I just gotta reply (can't leave well enough alone )

Me: I'm not asking if it's compatible with my motherboard, I'm not asking if it will work at 100mhz. I'm asking for the exact numbers off the processor so I know what I'm bidding on.

I have no intentions of buying this now, but I do want to see what he says. Man Ebay is a festering sore on my arse!

Heh, I got an old slot1 P3 500MHz processor cranked up to 750MHz at default voltage (1.6v).

I wish I could go higher but the max fsb on the Asus P3BF is 150MHz, and the 5x multiplier is locked.

Anyone know of any beta bioses for the Asus P3BF with higher fsb??

This processor already has a heatsink installed so that you can protect your investment!

this statement made me giggle

It will work flawlessly, all Pentium 2/3 processors can work at lower bus frequencies i.e. all Pentium 2 processors reated at 100Mhz bus speed can work @66Mhz and all Pentium 2/3 processors reated at 133Mhz bus speed can work @ 100Mhz and 66Mhz bus frequency.

the seller answered your question correctly

using reading comprehension, you can clearly tell it is a 133fsb chip.

addiotionally you could have just asked him for the numbers on the chip and plug it into the intel processorfinder on their site.

just get a tualatin celeron or if you cant do that then a high coppermine celeron and it will run circles around your p3.

we have a bunch of i815 boards, complete with 866, 933, or 1ghz P3's and 128mb of pc133 memory at work... could use a good home

Totally, itll work, but the clock speed wont be 1ghz unless the multiplier is adjustable, dunno if they are on slot 1 PIII's or any PIII's for that matter.

gots a 733 (not slocket) sitting in the basement in a HP system O_O.. not sure what the fsb is

I use a slot1 733 coppermine as an IPcop server and it's still going strong!

Whoa, I had an almost identical setup BITD. Had a Coppermine slot 1 P3 550 running at 825 on my P3B-F board. Couldn't get it to take any video card at 100MHz AGP, so ended up running a Voodoo3 2000 PCI that was overclocked to 180 (almost 3500 level). That setup was the $h1t for early Quake3 days!

The P3 chips at 733, 866, 933 and the Tualatin chips won't work at speed or at all on the Dell BX chipset board the OP has. Also, P3 has locked multiplier. All the Tualatin P3 chips are 133MHz FSB. You might be able to run a Tualatin Celeron 1.4GHz using a slot-T adaptor.

Now, P3 1GHz at 100MHz FSB with 10X multiplier does exist, but very rare. I actually used to have a PPGA version (socket370) that I sold to another forum member here. We both were running that bad boy at 1.33GHz - YES, a Coppermine core P3.

Sounds like the seller doesn't give a crap whether it works for you or not. He just want yo munny.

 

[AkumaX]

i got 2 x Alpha P3125 HSFs if you want

it's probably a 7.5 x 133 proc (you guys are right, read between the lines and since he said you can set it at 100 or 133, its probably at 133)
and obviously, you could set it at 7.5 x 100, to get 750mhz, but then why

youre better off getting a tualatin celeron and using a slotket converter

I never said it will , To be precise it will worke at 750Mhz, 1Ghz/133Mhz bus chip has a multiplier of 7.5 (1000/133 = 7.5) working @ 100 bus frequency will give it an effective speed of 750Mhz (7.5*100 = 750).

dunno if they are on slot 1 PIII's or any PIII's for that matter.

There are, and quite common, but the 1Ghz/100fsb/slot 1 version is extremely rare, Intel didnt produce a lot of these, and i'm not sure about this but i think it was only available to OEM (mainly Dell).
