Anyone have 4GB in an Asus A8N-SLI Premium?

[Paul Adams]

Had my current system since September last year, an A8N-SLI Premium motherboard with paired TWINX2048-3200C2 modules in slots A1+B1 (as per manual).

Recently bought a couple more identical modules to populate the other 2 slots, but when installed the system spews out the recorded message "system memory error" over and over and refuses to even give the graphics card BIOS message.

Ruling out faulty memory, I swapped my original 2 sticks with new ones - booted fine.

Updated the BIOS to 1009 - still won't start up with all slots populated.

Tried populating slots A1+B1+B2 - POST screen reads 1GB installed, BIOS screen says 3GB installed, and Windows says ACPI error and refuses to start.

Tried populating A1+B2+A2 - "system memory error" once more.

According to the manual, all 3 1024MB module manufacturers on the "DDR400 Qualified Vendors List" are listed as NOT supporting 4 modules in dual channel mode, and at the end of the same table they ARE listed as supporting it.
Good, eh?

The reason I went for the Corsair TWINX2048 memory is because it was on this compatibility table.

So, on the off-chance, has anyone managed to install 2 lots of paired 2GB Corsair TWINX2048-3200C2 modules in an Asus A8N-SLI Premium motherboard successfully?

Alternatively, if you have 4GB of memory of another type in the same motherboard, can you reply here please?

Try set memory to 2T. If that doesn't work, try reduce speed to DDR333, 3-4-4-8, to see if its memory problem.


I had problems getting 4 sticks to work with my A8N-SLI Deluxe&Premium. (4x512, had to use DDR266-3-4-4-8 to be stable, where the stick ran rock stable DDR470-2.5-4-3-7 on DFI)

I was also running Corsair Valueselect 4x1GB (not anymore) on my DFI NF4 SLI-D at DDR500-3-4-4-8-2T.

I am sure it is not impossible, but apparently the board is picky in the first place, and even more so when you try 4GB.

Aha, you star!
As it wasn't even getting to the POST I figured the board (or a slot) might be screwed, but I set the memory timings back to Auto, inserted the modules and now it's up with 4GB

Seems to auto-detect the RAM at DDR400 if there are 2 modules in dual channel, but DDR333 if all 4 slots are in use... I had the memory settings tuned manually to the ratings on the modules (DDR400 2-3-3-6 1T) which works perfectly for 2x1GB.
