Hello,

This weekend I tried to build a new workstation using the above
components plus a Maxtor DiamondPlus 9 120Gb drive, but I get all
kinds of problems right from the start of the OS installation. Because
I have ruled out all the obvious reasons for my problems (faulty disk,
cables, etc. etc) my question is this:

Can I combine a Asus A7V8X-X motherboard (the asus website states:
"DDR400 memory only work with 200/266MHz FSB CPU") with an AMD Athlon
XP 2500+ 333Mhz and PC3200?

Can somebody please explain (or give me an url) what the difference is
between PC2100, PC2700 and PC3200 (including confusing name
conventions)? And how this relates to the FSB values of a mobo? I
cannot find any decent information on the net, although I am convinced
that it must be out there... :(

Thanx BIGtime in advance,
Bona 'weekend-down-the-drain' Party

According to this link (watch for wrapping) - the A7V8X-X is a recommended
board for the XP 2500+

According to the Crucial memory selector at DABS...

http://www.orderingmemory.com/dabs/index.asp?model=A7V8X-X&x=9&y=12

....PC3200 is suitable for your board.

Have you checked you have the latest bios? What sort of problems are you
getting? etc Shawk.

You can use PC2700 but it's worth the little extra to get PC3200 so
you can over clock.
Can somebody please explain (or give me an url) what the difference is

PC2100

is 256Mhz
PC2700

is 333Mhz
PC3200

Is 400Mhz

If your FSB is 133 you need PC2100(256Mhz) or higher RAM to run
stable.
If your FSB is 166 you need PC2700(333Mhz) or higher RAM to run
stable.
If your FSB is 200 you need PC3200(400Mhz) or higher RAM to run
stable.

Your FSB is 2x that's why memory must be double the CPU FSB.


In BIOS go to:
Advanced Chipset Features-
System Performance-
User Define-
Memory Frequency-
100%.

That Locks the CPU FSB in sync with the RAM. Even if you run stable
without them locked, performance can be awful with them out of sync.
My system would not run right until I made that change. At post mine
shows "Memory 200FSB".
 
Thanks for the reply guys, problem solved.
I bought an AMD 2500+, I know this number is not the actual speed but
some bizare marketing trick, but I didn't know (and could not find
anywhere) the speed I was supposed to enter into the BIOS.
I used 2200Mhz, thinking this was low enough :), but apparently I had
use the 1800Mhz setting.

Now everything works fine... (700 Mhz's lower ;)
