Ram not detected

Hi, I am running an Asus A8V deluxe motherboard and i previously had 2 512mb sticks of geil ddr400 ram in. I decided to add 2 more sticks of the same mb/speed only kingston brand. The only problem is my computer is not detecting the ram at all. Post Bios message says only 1024mb is detected and my system info only says 1GB detected while i'm in windows. Any clues to what is going wrong?

1. BIOS rev?
2. What's the info on the memory?
3. Have you tried just adding one DIMM at a time?

Bad RAM? Bad mobo?

Uhhh then you'd have POSTing issues.

I already flashed to the latest version

Ummm I'm not sure what you mean by this i have 4 Sticks of 512MB DDR-400 2 of them are geil and 2 are kingston. I have tried using all of them separately and they all work. My board only accepts them in pairs though i can't have 3 in at once. Only 1, 2, or 4 because it only wants dual channel configuration.

Says who? (do note that I have the same board).

1 = no dual channel so therefore that should convince you that it doesnt "want" dual channel. :) (i know *you* want dual channel, but its more important to get the systemw orking first :))
 
So it's definitely just the last two slots(the black ones) that aren't being detected. It's running in dual channel mode fine with two sticks in the blue ones, I ran CPU-Z to take a look at everything. I just need to know how to get the last 2 detected.
 
hmmm i guess that's possible. It's a brand new motherboard, but is there any way to test that aside from buying another motherboard?
 
if its brand new try returning/exchanging it, or you can use the manufacturer warranty but that takes longer for results
 
well the system works with all 4 in, but it only detects 2.

Which is why i suggested you try 3. (and if it doesnt detect 4 and you've got 4 then it doesnt work)
 
Ok the two new ones may not be the same
CAS Latency (CL). If you read your manual on your
ASUS Mobo it would say something about all four must be the same
Latency in order for dual channel to work.

Correct however hes saying that when he populates 4DIMMS the system doesnt realize there are 4 sticks of memory in there
 
Thats what I mean I got and ASUS and bought 2 Rams thinking I had 3 Latency to mach the other 2 and ended up with 2.5 latency. This made mobo act up pc did not see 4 rams untill I put only the two new ones in. I was able to use 3 rams not dual but not four being that it activates the dual mode. Thats when I read the manual in reguard to dual mode.

1. HUh??!
2. I dont think the immediate problem is lack-of-dual-channel (otherwsie it was poorly phrased) but rather lack of detection period, dual or otherwise

So a 6DIMM board?
