Hello

Does anybody know what is the fastest possible cpu on an ASUS A7V333
(I have an Athlon 1800+ and I wonder if I can install a 2800+)

Thanks
 
It depends on the pcb revision number of your motherboard.
Up to and including Rev 1.02 the maximum FSB is 133 (266DDR). This limits
you to an XP2600+ 266FSB (quite a rare cpu).
If you have the rev 2.0 then you can run 166FSB (333DDR), this would allow
you to use 333FSB cpu's up to XP3000+
 
Thanks for your answer !
I'm sorry but I don't know were I could find the pcb revision number of my
MB..
Thanks for your help

Model and Revision number should be printed between the PCI slots.
 
there will be a sticker on the board some place...or it may be 'painted'
onto the board...A slight correction to my earlier statement...any revision
below 2.0 only runs 133FSB (I think there may be a few rev 1.04 boards on
the go)
 
I checked my bios and mb version and settings and came up with the following
info:

Brand : Asus
Type : A7V333
Bios : 1017
Revision : 1.04

From the bios i can select in manual mode the following clock speeds for my
cpu:
from 100/33 up to 227/45 which includes the 133/33 and 166/33 settings.
Voltages from 1.650 up till 1.850
Currently running an AMD Athlon XP 2400+, using the multiplier override
setting in the bios so it runs on 2133 MHz instead of 2000 MHz

I thought the faste cpu that would fit would be the 2400+ but now i am not
so sure, any suggestions from the group?


Kind regards,

Your board only supports 133FSB...that does not mean you can't overclock to
166 but your pci and agp would be well out of spec so problems are likely.
 
isnt it the case that the first number is for cpu and the second for pci?


so 166/33 would result in same pci freq as 133/33???

I haven't tested but am thinking that eventually i'll buy the latest 166
MHz Athlon supported by the last BIOS (1018(beta)) and then running it
manually underclocked to 133 MHz bus-speed (so as not to overclock the
PCI/AGP busses). Should work i hope/think.

Good luck. And report back if you try.

Yes if the motherboard chipset had a functional 1/5 divider.

But as i understand it, _that_ is a difference between the 1.x & 2.x
versions of the A7V333 boards (the one known difference).
And thus this can be the reason for the lack of official support for
333MHz Athlon (Barton) CPU's on for the 1.x versions.
(It may also be that a subset of the 1.x boards have a functional 1/5
divider, but i don't know how to find out for sure.)

And depending on what PCI devices you have, it may still be possible to
run your CPU-bus at 166 MHz ... or somewhere between 133 & 166 Mhz, even
on a A7V333 1.x board.
