Need HELP on XMS3200LLPT - Not being recognized

I just installed a new stick of Corsair 512Mb XMS-PC3200LLPT into my system. BD7II-Raid Motherboard

Problem is:
The stick only shows as being 256Mb single sided in both the BIOS and every program that I have. (CPUz, Sandra 2001se, Sandra 2003, Memtest86, etc.)

Looking a Sandra motherboard information it shows only one bank instead of both banks.
1.) Tested slot 1 on mobo and shows Bank0
2.) Tested slot 2 on mobo and shows Bank2

Could it be that a memory controller chip or something on the motherboard is not reading the second bank, since both Bank1 & 3 are not showing up?

I did test the chip in another board ECS K7S5A and it shows correctly as 512Mb stick.

Have you tried to change the memory slot of your memory?

Yes - Put the memory stick in all three slots.
Same story - Different slot

Is it the same chipset? It might be that the abit board doesnt support double sided memory....or u got a defective board, contact them.

go check out your mobo manual. see if it supports that type of memory. thats what my problem was i think on my boared. the abit BH6 board didnt want to recognize my double sided stick of 256 megs ( only read 128 )

if thats the case.. go see if you can exchange your memory for single sidded 512megs
