Hi Guys

Just built PC in signature and get the above. BIOS says 4088MB usable and Win says 4GB. Bios is 0704.

CPU-Z says i have 3 sticks of 2GB. MemTest (HCI Design) ran for an hour with no error.

What should my next step be please...?

Ta, Mark
 
Yes i have read a few tales of this but did not want to just start doing stuff without a bit of guidance.

Don't know when to involve OCuk, not sure I want to tinker too much, and bnot sure whether its memory, mobo or chip that might be at issue.
 
Thank you all for your replies, seems pretty much as i had feared.

Mine has never shown 6GB! whereas others seem to reboot and find it!

Which Memtest should i be running, i got mine from HCI Design, is that the one? Might have a look at the CPU pins, that way i can loosen off the H50.

Are OCuk obliged to ensure this combo works?
 
@TomC Ta for the google!

Ah! dxdiag says my Graphics card has approx Total Memory of 2803MB!
So my card is 1GB Memory so how do i get 1800MB back!!!
 
Good News ARC

None of my 3 sticks work in the A1 slot so methinks it is mobo for me that needs rma. Will see how OCUk want to play it it.
