Athlon XP 2600+ running at 1200 MHz

[theprobbka]

I can't figure out how to make it run at normal speed (like 2.5 GHz) anywhere in the BIOS. Any ideas? It's ridiculous...

try using 133fsb in the bios

I assume his xp 2600+ is using 166fsb

and 2600+ is not 2.5ghz.

AMD ATHLON XP 2600 /333 FSB PROCESSOR CPU
Specifications:
CPU: 2.08 GHz
Type: XP 2600 Thoroughbred
Cache: 256K
BUS: 333MHz
Socket A

What motherboard are you using?

 

[theprobbka]

Shuttle AK 39 N

And yeah I was just guessing 2.5 GHz I knew it was something way larger than 1200 MHz...

Thing is, I can't find where to switch FSB or anything in the BIOS... all BIOS options seem worthless...

 

[theprobbka]

I'll check in the bios but I'm not sure where to change the FSB

change it in BIOS where all the CPU options is at. what mobo do u have?

the motherboard is shuttle ak39n. I went into the bios but you can't change fsb from there, you have to set jumpers. so i looked at the jumpers but the jumpers can't set fsb any higher than 166 MHz... and it won't even boot higher than 100 MHz. It doesn't make sense. I'm confused out of my mind here.

is the processor you have the barton 2600+ according to shuttle they dont have offical support for 333mHz FSB CPUS for this board

http://us.shuttle.com/specs.asp?pro_id=251

unless this is incorrect.

however it should work at 100 (100x2 = 200mHz) reguardless, not sure why it wont boot at that setting




(since this post I have check the detailed specs and it does indicate that it supports 333 Mhz FSB CPUS)

Not sure what the deal is, I would try with just one stick of ram, and no peripheral cept Video and HD and see if it works then, other then that I'm not sure, It really should work at 100 no matter what you have in their, unless something is defective.

Also what kind of ram do you have and what timings are you running them at?

It is possible that there is a jumper on the motherboard that you will have to change in order to enable the 133 FSB (or 166 if it is available). According to this document, the AK39N does support the 166 (333) FSB, so it may require a BIOS update to enable the 166 support.

[ EDIT ]

According to Shuttle's CPU Support page, this mobo supports up to the 3000+, so you really shouldn't have any problems once you find the proper setting/s.

I just put my new system together with this board. It does support 166 FSB. I have my XP1700+ TBred B running on a 186mhz bus speed (default voltage).

Is your 2600+ a 133 or 166mhz BUS CPU? You have to set the jumper to its proper place. The CPU jumper block has 4 pins. Mine came set at 100mhz. With it set at 100mhz, you have the option of 100-132mhz in the BIOS. With it set at 133mhz, you have the option of 133-165mhz in the BIOS. With it set at 166, you have to option of 166-200mhz in the BIOS (all in 1mhz increments).

Double check it in your manual, but I believe the setting for 133mhz is no pins shorted & 166mhz is the bottom 2 pins shorted (I'm at work now & so I cannot look to verify it).
