What processor???

spud17

I think turbobobs cracked it.
I had (still have-spare) an Athlon XP2400, runs at 2000Mhz, but if you altered anything in the BIOS it would sometimes go to PC100 settings rather than PC133.
The processor speed would then show as 1500Mhz.

turbobob and spud17 & others, prize two beers ! :beer:

Techie Quiz Question : - at the same time as the Model B was released a very particular MOBO manufacturer forgot to re-code part of the BIOS. This resulted in a default front side bus of 400 [ 200 up & 200 down ] so the 1200 Model B Barton ran at full whack !

Which MOBO brand / model ?

Richie, I may now be 50+, but I've only been around computers for about 5yrs, and the little bit I do know, is what I've taught my self, and learned through this forum.
So don't be asking stuff like that! :beer: <- cider not Guinness

No idea on that sorry I've encountered the exact issue the OP refers to though on my Abit NF7S. Early BIOS's showed my 2500+ XP-M as "Unknown CPU" but ran it at a default speed of 600mhz. Later BIOS's identified it (I always ran it at 200mhz x 11 anyway I think, it was pretty flexible).

Thankyou for your help, i'm not any kind of expert or even close lol So could you tell me what i need to do ( in idiot language plz!!!) Thanks again

OK as simple as possible..

Before you start, find out which key gets into the BIOS setup program on your PC. I'll assume it's "Delete" but it could be something else. It should say (very briefly) when it first starts up which key enters the setup menu.

1) Turn on PC
2) Tap "Delete" (or whatever) repeatedly as soon as it's switched on.
3) Once the BIOS setup appears, look for the menu to setup CPU speed. There is no mouse in the BIOS program so you will be navigating through the menu's using the keyboard (cursors, return and escape etc.) It might be in "Advanced Setup", "CPU Menu", "Softmenu" etc. It depends on the make/model of motherboard but they generally have a similar design.

BEFORE YOU CHANGE ANYTHING MAKE SURE YOU TAKE A NOTE OF WHAT THE SETTINGS WERE PREVIOUSLY.

This is based on your post above saying it is an Athlon XP-M 2800+

4) You might find the CPU speed is set to "Auto" or something like that.. Change it to user defined.
5) Set the external clock speed to 133mhz
6) Set the multiplier to 16x
7) Set the core voltage to 1.65v
8) Press the appropriate key to save and exit the BIOS.

If all is well, job done. If not, then this is why you need to make a note of what settings you are changing, in case they have to be changed back.

Abit NF7S Model number / Rev number ?

- all BIOS's have modders groups who reverse engineer BIOS to see what the engineers left behind, and if it can be useful !

- your three clues are, it was ABIt, It was very particular revision NForce chipset, and it ran on a 12 multiplier !
- at the time a £?? slug would run faultlessly at the same speed as a three times £?? slug !

The term slug might be a fourth clue

70+ in my case, and nowt wrong with scrumpy, spent my formative years waking up behind strangers sofa's looking for a bacon banjo !

Cider it is .. .. .. .. :beer:

I had a NF7S v2.0 (the best one)

OK then I guess it was some sort of bug in an NF7S v2.0 that resulted in XP2500+ running at XP3200+ speeds by default? Close? If not I don't know. Not getting anything from the slug reference sorry.

It often seems to be the case that cheaper parts were the same silicon as the more expensive ones, just set to run at a different speed. E.g I had one of the early Core 2 Duo E6300's that I ran for a few years at something like a 60% overclock (it just about matched the "Extreme Edition" of the time which cost an arm and a leg) with no fancy cooling, no additional voltage.
