hi i just got a processor off a freind which is a amd 2600 now the trouble is that it is only showing up as amd xp2000.I wanted to check my fsb to see if that was the prob and came across this problem that i cant alter it and also i cant see what frequency and voltage its set at.
i have an msi V Class KM3M-V mainboard
thanx hope someone can help its ragging my brain to bits

Read your manual. To change the FSB to 166MHz (333), all you have to do is move the jumpers (SW1 & SW2) to pins 1-2. The jumpers are located next to the battery.

Are you using the onboard graphics or a 'real' video card? Do you have the latest BIOS version (v. 3.2)? Have you run thru all the BIOS settings & adjusted them accordingly, or did you just use the default settings? Most boards autodetect CPU voltage...& frequency is the same as FSB. What RAM do you have? PC2100 (DDR266) probably won't be able to run at 166MHz (DDR333).

i have 256 real graphics card not onboard,the bios is the latest version, i have 512 ddr pc2700 and as far as i know the bios is all set up correct , im not that clever at the bios thing so i could be wrong

OK, what about your power supply? Have you tried disconnecting the HDD, optical drives, pulled cards, etc & see if you can get a display under a lighter load?

There are a few 2600 cpu with different core (T-bred,Barton, Thorton, sempron), T-bred normally is running at 133, the other 3 are running at 166. You need to take out the heat sink and find out manually what the cpu model is, it should read something like AXDA2600DKV3C etc, do a serach to find out what your cpu FSB is based on the model.
remember to re-apply thermal paste or else your cpu will be fried.

The 2600+/333FSB (Tbred) & the 2000+/266FSB share the same multiplier (12.5x). There are two other versions of the 2600+, but one has a 16x multiplier (266FSB TBred), & the other 11.5x (333FSB Barton).
It seems it would just be a simple FSB change from 133MHz to 166MHz to get this CPU to run at the right speed, but for whatever reason, he can't make it work

Have you checked the MSI cpu support table
for your board to see of your board modell
and revision will even support that cpu ???
