I havent been able to go and have a look at his machine myself. So any advice that i can pass onto him would be appreciated.

This is his problem:


I have a new build and purchased 2 x Kingston Blu 4gb sticks for it- both are recognised in the SPD in the bios yet it only shows 4gb total memory, Windows is the same, 8gb (4gb available)

Pics of RAM and Bios - windows pic shows 2.96gb available as I had on-board graphics on to see BIOS: https://drive.google.com/folderview?id=0BzGEg1Gp1OnkMWY5dkZhN2Y3RGs&usp=sharing

I have read nearly all the topics and checked off everything - msconfig- max memory unticked, Windows 7 ultimate 64bit.

My motherboard is an Asus F2A55-M LK2

I have uploaded a new folder with images showing both the bios, the RAM and the slots. I now have 2x4gb RAM I can't use - please shed some light on this as it is putting my head away. I have 3 sticks of 4gb in total and all 3 work in slot A1, if placed in B1 the computer keeps looping trying to post and doesn't start, is this significant?

Or am I best returning the 2x4gb sticks and getting an 8gb to end my woes? I really don't want to have to rebuild this machine again after only doing it last weekend.
