Vista 64 not seeing 8GB of ram fitted, only sees 4
Vista 64 only shows 4GB ram and not the 8 fitted. I have googled this and apparently I have to set memory mapping in the bios but cannot find this option in the Award Bios.
How much RAM does your motherboard support?
well his motherboard, the XFX 790i Ultra, supports Up to 8GB of DDR3 2000/1600/1333MHz memory
Dual Channel architecture. SO the only thing I can think of is he's using two different frequencies in the slots or one of the ram is fried.

matching 4 sticks bought at same time all brand new. As rabio says, supports upto 8 gig. will try memtest on the ram and report back.
What is max of mem on each slot that motherboard specs called out? You should check manual to sort this out.
try to look for Beta bios releases that support remapping
If the board takes low density and you have high density modules that would explain this.

I suppose the main question is: Is there a place in the bios that allows for memory mapping that I have just not found? Ta for the responses guys.
I'm not an expert on that one but it seems to me that kind of memory mapping is all done in the OS.
[As in the BIOS only maps the first 1MB(??) it needs for it's own use.]
If that were not true then reverting from a 64-bit Windows OS back to a 32-bit version wouldn't revert you back to the 32-bit/4GB limit on RAM.
If I'm out in left field let me know guys.

have you upgraded to vista service pack 1? i know before i upgraded to sp1 vista saw 3gb, then afterwards when i got sp1, it showed 4gb. so check into that!

got service pack 1, and vista is seeing 4gig not 3.5gig. i keep reading that it is a bios setting but cannot find the setting in the bios. This is the help I require I think. How do I set memory mapping in the award bios?
oh , i understand now. well you go into bios, then settings, then memory settings. check this out.

it may show you how to optimize the whole thing, but basically just look for something called physical memory and change that to auto i believe it is. good luck!

sorry guys. this is a bit embarrassing, but the ram was only 1gig per slot and not the two I thought I had paid for (live in spain and do not yet speak the lingo).
