Chaintech 7VJDA


I may actually be insane.
I have a ChainTech 7VJDA main board, and I want to upgrade my current CPU, but I can not find the max clock speed that this board will take.

Can anyone help me?
All i could find was from the bios version log was
7VJDA 4 31D9 2002/1/29 Feature: 1.Support AMD CPU XP 2000+ ,2100+ and 2200+ .
And the latest bios revision just says
7VJDA 5 0E93 2002/8/12 Feature: - Fixed windows install sometimes fail with FSB 133Mhz CPU,- Update USB controller register according VIA fixed Logitech M-S48A ( USB mouse ) can not be detected if SB version ( VT8233 0211CE ).- Fixed ACPI shutdown temperature fail .
So officially it only seems to support 2200+ but i would put money on it supporting the 2400+ (i believe this to be the last 266fsb cpu) there is no jumper for the Multiplier its just the standard bios/cpu auto detect feature.

(Been away a while so a bit rusty;) )


I may actually be insane.
Well I intend to bung a 2400+ in here, as you say.. it's the last 266mhz, so that was my reckoning :)

Un-fortunately chaintech's site is useless and their damned support form doesn't work >_<
They dont give an e-mail addy either.

A 2200 would be better than what I have now, But if I can definately get away with a 2400 I'd rather do that :)


I Have a similar 7KJDO Chaintech board with an Athlon XP support bios upgrade from Sept 2002.
This does support all XP processors on 266 FSB inc 2200+ and 2400+ .
However it goes into standby on reboot and half the time will not boot from entry into the bios either.
Debugging was suggested as not overheating and have 425w PSU .
Set the multiplier to auto ,as no facility over x12


Message to Speed B
For Chaintech support go to "support@chaintech.nl" (Holland).
They reply within 24 hours !
The Taiwan site support form does not work as you discovered.

this issue doesn't really say anything for the manufacturer. it's the older (KT266A) chip that's the factor in this.

Abit claims the KR7A-RAID (KT266A, as well) is only good up to the 2100+... but a friend got a 2400+ working in his, no problem. so there's no reason why a 2600+ 266fsb wouldn't work either.
