Most Phenoms post slightly better scores with 4 sticks than 2 when using unganged mode.

Each set of 1GB x 2 by themselves booted into Windows and ran an abbreviated test with Memtest 86+ without issue. Shrug.

If you notice, those Corsair sticks need at least 1.9V to run by default, whereas the DDR2 standard is 1.8V. The motherboard may be running at 1.8V, which may seem to work fine for 2 sticks but obviously is failing on 3 or 4.
dragmor wrote:This would be my pick so far. RAM can be very sensitive to voltage. Since your sticks need 1.9v set the value to that with 2 sticks installed then but the 4 in. Maybe even set it to 2.0v if 1.9v doesn't work.

After re-reading your post, I just realized that this is an IGP board -- are you running with the integrated video enabled, or an external video card?

I am running an 8800 GT.

Is the IGP disabled in the BIOS? (if not, it could still be causing problems)

I was running a Gigabyte 780G motherboard just fine with 2 sticks of Corsair RAM. I saw in the TR review of my motherboard that they ran 4 sticks of Corsair RAM without issue (even running tighter latencies than mine!):
So I bought another 2 sticks of RAM for a total of 1GB x 4.
Of course, the system does not even POST with 4 sticks installed. It half-way POSTs with 3 sticks. It runs just fine with 2 sticks (either set).
Drrrr. That was $25 wasted after rebate. If only I had originally just bought 2GB x 2.
