Question about K8N Neo4 and TWINX1024-3200XLPRO ram.

[feverish]

Hello,
My question is this.
From what I gather the TWINX1024-3200XLPRO is Double side ram as opposed to single side. I do not know what that means but I think I am correct on this. In my K8N Neo4 motherboard manual, it states that the "Recommended Memory Combination" being Green(1st slot), Purple(2nd), Green(3rd), Purple(4th). I will just list the combos they say. Going from 1st slot through 4th and S=Single, D=Double
S,-,-,- DDR400
-,-,S,- DDR400
D,-,-,- DDR400
-,-,D,- DDR400
S,-,D,- DDR400
D,-,D,- DDR333
S,S,-,- DDR400
-,-,S,S DDR400
D,D,-,- DDR400
-,-,D,D DDR400
S,S,S,S DDR400
D,D,D,D DDR333
I already put most of my machine together and have the TWINX1024-3200XLPRO ram in when I saw this. The only problem is that I am running D,D,D,D DDR400. While sitting in the bios last night I noticed that the modules on DIMM 3 and DIMM 4 were being worked pretty hard according to the leds on top and DIMM 1 and DIMM 2 were not having any activity. Someone please explain to me what all this means and where I need to go from here. I will also add that I have booted up into the bios and all 2 gigs of ram are showing up. I really just want to know what will happen if I use it this way. Do they even make 512 single sided ddr dual channel ram?
Thanks,
David

It could be you are stressing the system enough to use all 2 GB, but . . .

When you boot up, make sure as it enters the BIOS that the 2GB are seen also.

1. Does the BIOS have a memory check - what activity are you seeing in all four chips as this runs?

2. You could try going to memtest.org and using their memory test tool. Run a few of the canned tests and see what happens also.
