K7VZA rev 3 CPU help

[jeffk55]

I recently decided to update the box w/ this MB (see Dead motherboard? thread for the fun w/ BIOS part) and at one point wrote to ECS, who politely informed me "we could give a rats .... about this board, your on your own" But politely mind you.
Anyways after I updated the BIOS to the very latest, the BIOS notes said " Update to support AMD Athlon XP 2400+ & 2600+ CPU sign on" 11-14-02 BCE I think. Just kidding.
6 million dollar question? Which cores? I assume just thoroughbreds and not barton ect.
Anyone have experience w/ CPU's beyond the original listed Durons' Thunderbirds ect?

I used a 2400+ barton in a k7vza rev 3.0 about 2.5 ago (the mobo has died since then). It worked just fine, although the cpu was under clocked a bit, since the board only supports a 200mhz FSB.

Thanks for the reply. That was ver 1 of the board (only 200) Ver3 goes to 233 I believe.
Anyways I picked up a used XP 2400 thoroughbred core. Will let you know how it works (It will be awhile though)

Got A problem: Just installed the 2400... BUT can't get it to run past 200mhz FSB. ON top of that both AIDA32 (CPU ID) and CPUID (from AMD) list it as a 1800+. Now granted I can't get the BIOS to go to 266 without BSOD-ing Win 2000...but I thought this was a string value and not dependent on bus speed and multipliers.
AIDA32 also reports (CPU section) AthlonXP 1500mhz (7.5X200) 1700+......
Any advice. I think it is a 1800, seller insists it's 2400. Would like to get this to 266mhz to verify... NEED help here......
PS latest BIOS.....

UPDATE: CPU is probably a legit 2400+. Just can't get this board (Actually Win2000) to run at 266. No how, no way. Jumpers, BIOS settings, not working as to a stable OS. May have to look into some incompatability bewtween Win2000 and VIA and AMD-XP, and ECS ect. Success stories of running this board w/ 266 FSB and an AMD-XP processor would be helpful to see any differences here. In the process of patching Win2000 and see if that helps........

UPDATE: It's the 512mb RAM stick causing the problem. Stuck a stick of 128MB and it's cruising along (albiet quite doggy. Too under-RAMed )
512 just not stable at 266, fine at 200 and 66 (threw it in an old Tyan/Celron box.....)
