SLI Memory questions!

[Barry_B]

I tried search, but kept getting 'Sorry, this thread does not exist' or similar message for all the hits of 'EPP' and 'SLI Memory'???

Anyway, I have an ASUS Crosshair AM2 Motherboard (BIOS 0802) with an AMD 2.8GHz CPU and a 2GB kit of Crucial Ballistix DDR2-PC6400 SLI Memory running an 'Enhanced Performance' SLI profile, 2.2v 800Mhz 4-4-4-12 I think.

Questions:

A. What's the benefit of running the 'Enhanced Frequency' profile as I think this goes to 1066Mhz @ 5-5-5-15!
B. Do I need to adjust the 'CPU OC' in the BIOS too, if so by how much?
C. Do i need to consider anything else?
D. Is it worth it?

I'm a bit vague on the intricacies of SLI Memory and would like some more knowlegeable chaps to woalk me through the pros/cons if possible please.

Apologies if these questions have been asked before but the search wasn't helping me!

EPP or "Enhanced Performance Profile" RAM is designed for use with the NVIDIA 590SLI or 680SLI, when EPP RAM is paired with a motherboard it provides advanced performance memory tuning options, I don't believe your motherboard supports EPP.
Raising the RAM timing allows for a higher overclock,
Lowering the RAM timing increases performance.
Your RAM is factory set at 4-4-4-12 @ 2TCmd Rt

Thanks for the info, I read a few sites prior to your post and found out a bit more.

The mobo is an AMD 590SLI supporting EPP, BIOS options and boot up screen confirm SLI Memory Support and the RAM supports EPP as well.

The Enhanced Frequency Profile is 500Mhz, not 533 as I thought, according to CPU-Z but enabling it still keeps the RAM at 400Mhz? Not sure if I need to do anything else?
