Can't figure out memory timings - difference between ns, CLK and T??

[Skaven]

I purchased some Kingston Memory (4x1gb) at Newegg for my Asus A8N-VM CSM motherboard. With two sticks of the Kingston ram in, I get DDR 400 - but with all 4 sticks it ramps down to DDR 333 (yes, I made sure that the matching sticks are in the matching memory sockets). I called ASUS and they told me that I needed the exact memory timings of the ram to get it to run at DDR 400.

I found the memory on Kingston's Website and downloaded the PDF datasheet. It listed all of the timings in ns. So I called Kingston and they gave me the 3/3/3 CL/CAS/TRAS timings. So I went back to the BIOS on the ASUS board and all of my options are in CLK or T.

CAS Latency (CL)
Auto, 2.0, 2.5, 3.0

TRAS
5CLK, 6CLK ... 15CLK

TRP
2CLK 3CLK ... 6CLK

TRCD
2CLK-6CLK

TRRD
2T,3T,4T

TRC
7T-22T

TRFC
9T-24T

TRWT
1CLK-6CLK

Asus told me that Kingston should be able to give me the timings in CLK/T. Kingston told me that Asus should be able to give me the corresponding number for their BIOS. Didn't help me much!

I've tried all kinds of combination of settings... most of them locking up the system. I just want to proper settings for the memory to run at 400DDR! Didn't realize it would be this difficult!

I've been building systems for 10 years... just so you guys don't think I'm a newb.

Any help would be appreciated!?

Well...these boards do not run at 400 when all 4 of the slots are populated....they rather run at 333. Thats the problem with these boards...Intel do run...but Amd is a no go with 400 and 4 sticks...
