Hi there,

I was wondering if you solved this issue.
I have the same scenario.
I have 4 x 2GB Crucial Memory CT25664AA800.
I can boot with 2 x 2 GB in ports 1+3 or 2+4 and all is well BUT as soon as I insert all 4 DIMMS I have the same BIOS freeze as Spike is describing.
I have tried raising RAM voltage and MCH to no avail.
I have also re-applied the BIOS and still the issues persists.
I am wondering if a new BIOS release is on the way...

If anyone is running 8GB on this board I would love to no the brand of the RAM and the Motherboard settings.
I really need to get this working for a lab I am building.

Many thanks

As a pointer to anyone else who has this issue.
The problem is this particular motherboard only supports all 4 DIMM slots being populated if they are single sided DIMMs.

If you wantg 8GB of RAM in this board you will have to purchase 2 x 4GB double sided DIMMs and put them in slots 1+3.

Not an option for me as the cost of 4GB DIMMs is crazy. I have RMA'ed board to vendor and have ordered another Gigabyte board that is capable of supporting 4 x 2GB Double sided DIMMs : I went for the GA-EP43-UD3L Intel P43 board which supports upto 16GB , fingers crossed!

Hope this helps someone.
