k7s5a and T bred 2600+ - wont recognize proper speed

[imhotepmp]

As said above. I have a 2600+(266Mhz) with a k7s5a Pro 5.0 with the latest bios( HoneyX 8/25/03). Even after putting the FSB to 138/138 it only shows a speed of 1200 Mhz. In the BIOS it says Athlon XP but for some reason its not recognizing the correct speed. I also checked the ship id to make sure it was really the 2600+. Any ideas? I was under the impression that the latest bios would recognize it properly.

thanks for any help you can give.

What speed does cpu-z say?

2600 mobile? 133mhz bus? 2600mhz barton desktop is 200mhz bus i think. k7s5a can't do that. at best u can change it using speed fan to that in windows...well 166mhz. bug keeps it from even booting if set in bios. thats max. people use barton mobiles in that m/b. like me

I believe he's refering to the Model 8, Thouroughbred Rev. B 2600+. These processors were the final model mass produced with the 266MHz FSB in mind and should work on the mobo in question.

Have you tried resetting your BIOS and all jumpers to default? How about down-dating to a previous BIOS?

Yes, I tried resetting the CMOS several times and even tried an older BIOS with the same result.

It say 1167 Mhz with a mulitplier of 8.5 and FSB of 137/274 Mhz(I bumped it up from 133). So the speed reported by the bios is correct.

Hmmmm....
8.5 x 137 = 1164 Mhz
8.5 x 274 = 2329 Mhz

Shouldnt the muliplier be 16 so that
16 x 133 = 2128 Mhz ...the speed it should be running at?

u can't change multiplier with that board.. without socket pin hacks and such. so it sounds more and more like you have the higher fsb chip

Its probably not the 266 version but the 333 version. The 266 versions are VERY rare. So if it was a 333 version, I remember for sure the multiplier (probably 10.5) but the bios may be getting confused, and not running the chip correctly.

my best guess.

Well according to the AMD id page
here

its the 266Mhz version
so count that out.
