hey guys, a friend of mine recently gave me an athlon xp 3000+ (barton, 200fsb) for free to put in my system. the problem is, my computer doesnt seem to want to see it as anything more than a 2200+... i have a KT4V motherboard, and i know it doesnt support the 200fsb but since there are 2 varieties of this processor i was hoping i could get 13x166 instead and still have a 3000+. that doesnt seem to be working...i have my bios set at 12.5/13 multiplier and 166fsb but dxdiag and the screen at POST are still recognizing it as a 2200+ at 1.8GHz. i've just about run out of ideas, so could you guys give me a hand?

That was the main problem of the old Athlon CPUs. Some wont be recognized. I would suggest try making sure your BIOS is up to date. A friend of mine had the same problem and the closest I could get it to was a 2700+.

You might want to look into a new mobo as ones that support that CPU should be relatively cheap.

how did you get it to 2700? 13x166?
i may try getting a cheap supporting mobo if i can.

Weren't barton CPUs locked in multiplier?
I had a Tbred 1700 bus 266 (133) running at the same clock speed (lowered the multiplier) + bus at 400 (200). Quite interesting, but I've never did the opposite.

The later bartons did indeed have a locked multiplier. I'm not sure of the date they locked them, but am pretty sure it applied to all of the 200/400 fsb 3000s.
The best bet you have of getting close to xp 3000 perf, is to oc.
sorry.
Just checked. They started locking multipliers in week 38 of 03
The date can be read from the second to last line of writing, on the core.

lol, i just figured that out in my sleep! the multiplier must be locked, since changing it doesnt change the clockspeed. i feel like a dumbass now!
the odd thing is, the L1 bridges on teh processor dont seem to be cut, so is there another way of unlocking the processor?

yes, there were other forms of locking them... but as I don't remember (long time ago I read about the locks) I would suggest to search in the web the exact barton model you got.

ehh i just did something stupid...how do i restore the BIOS to the previous version? my system is still stable but now wont even let me have a 166mhz fsb, which the last BIOS let me have.
EDIT: nevermind, i fixed it.

just checked it out, its week 21 of 2004... that means i'm screwed, right? since its so late it must be one of the superlocked ones...

i've been reading up on this...apparently i need to connect a L5 bridge and then cut all the L6 ones!? i dont think taking a razor to my CPU sounds very appealing...eep!

does anyone know another way?

will this work?
