Win Vista Memory Problem

[dila1974]

Hello, I have M2N68AM-PLUS with 1 dimm 2gd( KINGSTON KHX6400D2/1G HYPERX DDR2 1GB PC6400 800MHZ GENESIS). I make a memory upgrade with one more dimm of 1 gd (KINGSTON KHX6400D2/1G HYPERX DDR2 1GB PC6400 800MHZ GENESIS). The bios read the 3gb memory but when the windows (vista home basic 64-bit) load I get a blue screen with stop and some numbers. If I let the windows to load with one dimm it works ok but with the two dimms blue screen. Can anyone help me. Thank you.

On some motherboards, all the RAM modules must be the same density (capacity).

It should work, it could be that the PSU is low in power and the extra ram, though not much more extra power required, is somehow causing the bsod. Your PSU should be more than 550 watts for this rig but f your video card is more than mid range, the PSU should be 620 watts or so.

As per QVL memory list
KHX6400D2LL/1G
This is not much different to what you have listed but is your ram single channel ram or dual architecture meaning that did your ram come in a kit of 2 or purchased as singles? You need a kit of 2 or paired ram.

Did you try booting with either stick on their own, both the 1 gig and 2 gig? If yes and they work on their own, try another 2 gig stick instead of the 1 gig you got.
