Why is Win 7 only accepting 3 sticks of memory
I have been unable to get Windows to accept a memory upgrade. I want to increase my memory from 4Gig to 8Gig (ie 2 sticks of 2Gig, to 4 sticks of 2 Gig). Windows hangs with all 4 sticks installed, but boots normally with only 3 sticks installed ?
It seems that the BIOS is happy to accept 4 sticks x 2Gig ... but Windows hangs: With all 4 sticks installed The BIOS will boot and the Windows boot screen appears (the four star animation) ... and then the system hangs !
By a process of elimination, I have been able to deduce that none of the individual sticks, or the individual slots are faulty: I can use any combination of 3 sticks in any combination of the four available slots, and it will boot OK and show 12 Gig of memory available.
I have checked that all 4 memory sticks are identical (Corsair Vengeance 1600mhz DDR3), and I have downloaded and installed the latest BIOS ... but the problem persists.
I note that the 2 original memory sticks are labelled V.2.12 and the second pair are labelled V.3.19, but I also note that they are happy running together as long as I only use 3 sticks (any 3 sticks !). The problem only arises when I try to use all 4 !!
Can anyone help
