2GB problem with Intel motherboard

We have the Intel DP965LT motherboards with Celeron D CPU at 3GHz.
These motherboard has 4 empty memory slots:
Channel A, DIMM 0
Channel A, DIMM 1
Channel B, DIMM 0
Channel B, DIMM 1

If I have 1GB at Channel A, DIMM 0, I can run both XP and Vista (32 bits
Ultimate and Business) fine.

I am unable to run XP at 2GB stable.
When I run the defragmenter, I will get blue screen crashed promptly.

I can run Vista (32 bits ultimate) at 2GB stable only when I have:
Channel A, DIMM 0 has 1GB
Channel B, DIMM 0 has 1GB.
but, it does has blue screen crash about once every other weeks.

I am unable to run Vista (32 bits) at 2GB when I have:
Channel A, DIMM 0 has 1GB
Channel A, DIMM 1 has 1GB.
I run the defragmenter and Vista will crash in blue screen.

So, what is the correct slot for 2GB?
Is 2GB works on XP and Vista?

they should fit in the DIMM 0 slots or the same coloured slots if your board
it newish.

are they a matched pair or just 2 x 1gbs you have purchased at different
times.

Fergus, all 4 slots connectors are the same exact color.

The 2 x 1GB DIMM memory are purchased from different companies at different
time.

Check you are running RAM at rated voltage. Dowmload and run Memtest86+,
you should have NO errors, even when run overnight.

I have 1GB at Channel A DIMM 0, Channel B DIMM 0:
Dual Channel (Interleaved) Mode Configuration with Two DIMMs
The following conditions do not need to be met:
a.. Same brand
b.. Same timing specifications
c.. Same DDR speed
