KT7a REV 1.1 : Athlon XP 2000+ : FSB 133 PROBLEM

Hello everybody,

Sorry to bother you with my problem... and sorry for my bad english too ! ;-)
And thanks for helping me!

Well, I have a problem with my old KT7A... and my new Athlon XP 2000+

Please, could you have a look to my computer?

Abit KT7A Rev 1.1 : Bios A935 (from OC-MASTER)
AMD AthlonXP 2000+ @ 1250 (12.5X100), 1.65V : 35°C/
256Mo RAM
64MB CREATIVE GeForce2 TI
HD : MAXTOR 120Go + MAXTOR 80Go
Creative Sound Blaster
AOPEN 300W? + APOEN HQ08
Plextor 24/10/40A and DVD Pioneer 106s

Well, the problem is that as you see, I cannot pass the 133, so it is impossible to run my XP2000+ at 1666MHz, even with the Bios of OC-Master!

When I use the 133/33, whatever the mutli is, the mother refuses to start and I have to reset and set it back @ 1250MHz… THAT IS NOT COOL AT ALL ! ;-)

Could you help me please?

Is there something that I missed... Well, it works fine in 1250... but I would like to have more potential ! ;-)

Thanks a lot

Have a nice day!

Apparently, the KT7a's that are not Rev 1.3's don't support AthlonXP's. They should because of the KT133A chipset, but Abit screwed up and they're not compatible with the 133mhz FSB or something.

Thanks a lot Johan851 !

Officially Yes, Only the rev.1.3 supports the Athlon XP.
But many people seem to be able to have it work, isn't it?

Here are some threads talking about it:

I had no problem at all to run my old Athlon 800 (8X100/33) @ 840 (6X140/35) so there was no problem with the 133.

But what is so magic on the Athlon XP that makes it not work like the previous ones?

If I couldn't reach the 133, how could I have my board reach 1666MHz?
16X100 ? Is it possible?

OK, I am a beginner but I can learn quickly if someone shows me a little what to do...

Thanks a lot!

Check if the processor is locked

Your XP 2000+ might be multiplier locked. Check to see if it is..that could be your problem.

Other than that, just follow the other threads you listed and see if you can find a multiplier/fsb setting that works. Nothing manual would work on mine...I had to go with the default settings.

Tanks a lot for your answer.

Could you tell me how I can check if it is locked?
For my old 800, I had to close the L1 bridges but on that one, it seems to be rather different...

For what I see, only the 1250MHz seems to be working...

I thought that all the Athlon XP where FSB 133...

Could you tell me which BIOS you would use on my KT7a Rev1.1?

Had a nice day everybody!
