Tyan Thunder K7-PCI @ 66MHz?

[flipdon]

i've got a friend building a server for our computer lab. he wants to build a dual athlon XP with the tyan board. but he wants to buy a 64-bit/66MHz RAID card to put in it. does the current thunder board support 66MHz? or is it a new board that has yet to come out that supports 66 MHz?

The current ver is only 33mhz PCI (5v) on the 64bit slots.

thanks for the info...

It's the 766 south bridge that holds the primary PCI bus back. Yet still, you can put that 66-MHz card into the 33-MHz bus, it'll work anyway.

When 760MPX chipset hits the shelf, we'll then have the same 762 north paired with the new 768 south that'll allow the 762's primary PCI bus to stay at 66.

yep, i'd wait for a MPX board to come out, almost here anyways. 66mhz support, plus boards that have oc'ing options!
(wouldn't it be cool to use an alpha 8045 and lower the voltages on the procs, for some passive cooling?)

you can use XP cpu on an MP board? I thought you had to use MP cpu.

You can use standard Thunderbirds in a MP board. The only difference in th MP and XP ( to my addmitidly low searching / tech knoledge ) is that the MP is "officialy" supported. I would think the new Morgan Duron's would be MP capable. Even the K6-2's had MP support, just no chipset/board for them.

Evadman, not quite. MP and XP have an advanced cache coherency protocol that drastically speeds
up dual processor setups over T-Bird. T-Bird and even Duron nonetheless run on those Dual mainboards
(if BIOS allows it), since the processors don't _need_ to have any special capability for it - each one
is on its own exclusive bus, and technically doesn't even see the other CPU.

K6 series CPUs did not have dual processor capabilities at all. K5 and Cyrix 6x86 did use an open
standard multiprocessing interface for which no chipset ever popped up.

so u mean to say ALL 64bit cards are all backwards compatible MHz-wise? sounds good to me...

when is the projected date for the MPX board? they're looking to build the server over x-mas break.
