TX79-XE and P55T2P4 with K6-2 500

I'm thinking about upgrading my TX97-XE and P55T2P4 Boards with a K6-2 500.
Has anyone experiences with this - especially about jumper settings for
clock/multiplier and CPU voltage? Is this possible at all (which motherboard revisions needed?)?

Any help appreciated, thanks!

TX97-XE and P55T2P4 : impossible

-> bad voltage : AMD K6-2 500 : 2,2v

-> bios support : AMD K-X-XXX is not supported.

-> clock at 66 Mhz : you need 100Mhz (5*100)for best performance.

-> multiplier : low multiplier ( 1->3-4 ?).

If you want a k6-2, you need a new motherboard.

Dear frache:
I investigated in the TX97 upgrade and found out that the K6-III 400 processor is the best processor to use with this motherboard.

Should not be a problem with MoBo rev. > 3 and a Bios rev. 112-01, found people in asus newsgroup using this configuration.

The K6-II with "CXT" core and all K6-III interpret multplier "2" as 6 - so the frequency setting for 400Mhz (6*66MHz)is no problem!

Hi, Mittelberger

Sorry for TX97, too many versions ... A part of my answer was wrong. I don't like make a bad answer. If you want, you can reject my answer. Contact customer service.

My links was :

Certified motherboard for AMD :

I find this evening this link :


In my opinion, best chipset for AMDK6-X-XXX family is VIA or ALI. Intel TX chipset isn't optimized for AMD processor.

I have a computer with an AMD k6-2-350 and a Gigabyte GA586SG ( SIS chipset). Good with Win9x, Office97, ... many problem with games : patchs for processor, patchs for AGP bus and video card (ATI), and patchs for games ... a nightmare.

Now i have a PIII , BX motherboard and everything is Ok.
If you must buy a (cheaper) processor , the best choice is Celeron. No compatibility problem.

Dear freache,

I don't think about rejecting Your answer, hope You're not very disappointed about that ... or don't You want the 100 points?

By the way, I just ordered a K6-III 400, will try it with my TX97XE Board.
I'm aware that the TX chipset is not optimized for AMDs, but the K6-III 400 is a cheap and powerful socket7 processor with it's 256k internal cache.
