problems with xp2500+

[danomite664]

I bought the retail version of the 2500+ from newegg.com to use in a computer i built for my girlfriends mother. I got the system up and running fine (for the most part) except for one pretty big problem. The mobo (MSI KM266 KM2M Combo-L) only reports the cpu as being a 1700+, which is quite a difference. The computer still runs but everything i have looked at so far has reported it as a 1700. I havent had a chance to flash the bios yet, but i will when i get the floppy working right. Does anyone know of any issues with this mobo/cpu combination or has anyone experienced this before? The system also has 512 mb pc2700 ram (kingston), WD 80 gig hard drive, and 2 optical drives, just in case that information is helpful at all. I really dont want to have to mess with replacing this so if anyone can help me, i would really appreciate it.

Does wcpuid and/or sandra still report the CPU haveing 512kb a L2 cache? If it does then everything is cool. Maybe flashing the BIOS with the latest update will allow it too report it correctly but it'll still run exactly the same FAIK.

You probably have to set it to 166fsb and make sure the default multiplier is used. This board officially supports 200/266 fsb. run wcpuid or go to my computer- right click -properties and see if the cpu is 1.83 GHz. It is probably reporting 1.47 GHz and therefore saying it's a 1700+ 133fsb x11 multiplier, it's supposed to be 166x11 stock.

i plan on installing sandra on her computer so i can check all taht stuff, just didnt have the cd with it today when i looked at her computer. i just didnt know if anyone knew of any issues or how to change it, but i will try that stuff. Also, the motherboard says it has a 200/266 fsb and that it will support this cpu, but the jumper on the motherboard only has the 100/133 settings. I used the exact same motherboard on the computer i built for my girlfriend and used an xp2400+ with no problems.

The XP 2400+ is a 266 FSB part. The XP 2500+ is a 333 FSB part...but the most you have is 266 on that board..Not a problem. Just, if the board will allow it, run it at 133x14. the chip will end up 36MHz over spec but the retail AMD stock cooler shouldn't have a problem with that at all. It'll never report the correct CPU type but long as there is 512kb of L2 cache that can be seen by the BIOS/OS you're fine there.

ok, i will try that. but what i dont get is why i even have to do that. if it's all that trouble to get the 2500 to work, they shouldnt say that the board supports up to the xp2600+, especially if their fsb is 333 when the board is only 266. also, whats the best/easiest way to change the multiplier and stuff on this board?

On second thought combo boards have a rather nasty habbit of forgetting such usefull things as multipliers.....

*Wonders why Windows auto-update picks now to turn on.....*

I thought I turned that silly thing off?

Early XP 2600+ chips where 266 FSB parts......there's your answer.

I'll look through that and see if something jumps out at me....

Might want to look into the stepping of that 2500+ and see if it's any good. :)

Section 3-28

You got access to the FSB there for some extra MHz....but it seems to be a bust on altering the multiplier......Looks like this mobo was dreamed up when AMD was still locking their CPUs.....so unless a bios update opens a new door that 2500+ will never run at rated speed on that board....but any other 133 FSB part currently around in large numbers will just fine.
