ABIT AN8 Ultra - 4 DIMMS Help

[Furtekjr]

I am having a problem with my new ABIT AN8 - ULTRA motherboard and I was wondering if anyone would be able to help.

I cannot seem to get my computer to boot up sucessfully with 4 DIMMs (I am using 4 sticks of Corsair XMS 3200). My computer boots up fine with 3 sticks of RAM, but as soon as I add the 4th stick, I get a series of long beeps and the POST display displays code 0.4 (which I believe means that there is a problem with the RAM). I know the sticks of RAM are fine (I tried each one individually and no error). I am pretty sure it is not a problem with the actually slots on the motherboard (since the board will boot if I have sticks in slots 1, 2 and 3 or 1, 2 and 4).

Any advise would be greatly appreciated.

What BIOS revision are you running? On Abit's BIOS page for your board, Version 18 says:

1. Enhanced some VGA cards compatibility.
2. Update nVIDIA RAID BIOS to V4.8
3. Enhanced DRAM compatibility.
4. Enhanced some sound cards compatibility.
5. BIOS compiled date: 09/27/2005

If you're lucky, this may help.

Does the same thing happen with any three of the four sticks?

I haven't tried to update the BIOS. I am actually still in the process of reassembling the computer.

Thats the strange part, so long as there are three sticks it will boot fine. I have tested all 4 sticks.

You got my best quick take. I'm headed out to a party. Hope the BIOS flash helps.

The board will only run 4dimms in 2t mode, set the bios for the ram to auto or switch it to 2t

No luck. No matter what I do, with 4 DIMMS the board refuses to boot with 4 DIMMS.
