What is a QVL memory table

I am going to get a ASUS A7N8X delux motherboard and they give this
QVL table in the specs. I assume that is workable system memory for
this board. Is that correct?

Also, the table lists DDR400 and DDR333...since I am going to get an
AMD ATHLON XP 2800 "Barton" 333 FSB...I assume I need DDR333 system
memory chips. Is that also true our could I use the DDR400?

Thanks

QVL stands for "Qualified Vendor List."

In most cases with mobo manufacturers it is a list of compatible memory (as
this is the largest worry as far as compatibility goes.)

It's likely compatible with DDR200, 266, 333, and 400 ... you can use
whichever you choose. I would recommend you go ahead and get 400. It can be
clocked back to 333 if necessary, but will grow with your system. And the
price point is just about the same.

And yes, you can run your RAM at 400 while leaving the FSB at 333 ... in
fact, why would they put DDR400 support on a board that had a maximum
processor bus clock of 333? (as this one does)

As a side note, a DDR400 module that is rated at CL2.5 will easily run at
CL2 when clocked at 333 ... this offers a speed improvement over CL2.5
DDR333 chips (which most are) even though it's not clocked any faster.

One more note, as this is an nForce2 based board you will want to have two
RAM sticks in dual-channel mode for best performance. But you probably
already knew that.

Actually, the PCI rev2 version of this board has 400MHz fsb support - most
suppliers now supply the rev2
The earlier version also has the support with a BIOS update
