Hi, I never really understood what to set the memory to so I've always left it at default. But I'm sure there is better setting to make better use of my installed memory.

What I have ( I hope this is the rite info )

A7N8X Deluxe rev 2.x
BIOS 1008 (not sure could be 1007)
2500+ Barton 333FSB - (set at 166MHz, Auto, 11.0x, Optimal)
Three Stick of CORSAIR XMM DDRAM 256M 32X64 PC-2700 C2
(set at AUTO, Optimal, 7,3,3,2.5T) I'm sure Dual-Channel is on.

Thank you
Jim

The Corsair XMS PC2700 RAM should be running at 2-3-3-6 (or 6-3-3-2 in your BIOS).

"Best" memory timings are 2-2-2-5. Whether yours can run at that (and also remain stable) is a question of trial and error. 2-3-3-6 should be a given, and chances are at least one of those will run tighter.

Keep in mind that beyond benchmarking, the average user is not going to notice any difference in real world performance.

As for dual channel, are you running 3x256mb dimms? If so, you have 512mb in one memory bank and 256mb in another:

Slot A1 = 256mb
Slot A2 = 256mb (A1 + A2 = memory bank one)

Slot B1 = 256mb (B1 = memory bank two)

You want equal amounts of RAM in each memory bank, so in other words, a 512mb dimm in slot B1 to match the combined totals of slots A1 and A2. Make sense?

Thank you, and I would have never pick up on that dimm slot item, I was under the idea that you had to have match dimms in all slots, well I now know what I want for christmas.

The other sad thing is, I just now changed the BIOS setting for System Performance from Optimal to Aggressive.

To make these changes I should change this to User Defined?

Again thank you OCNoob and One4yu2c

Yes, change to user defined and you can, well, define your own timings. :)

You might want to check what timings they defaulted to at the Agressive setting before making any changes though. CPU-Z is a handy little program for looking up that information from within Windows, as well as whether you're running dual-channel or not.

Oh, and to address this quickly, you were close. :) You want them matched in each memory bank. If in the future you were to use two sticks, you want one of them in either A1 or A2, and the other one in B1. If you put both in the A slots and leave B1 empty, you'll be running single channel.
