I have scene similar posts, but they found the solutions to be incompatible memory speed (not 800Mhz for DDR2) or the improper placement of memory on the board.
I have a P35 Platinum Combo MSI motherboard with an Intel Q6600 CPU, and 2X2GB Corsair XMS2 DHX PC6400 1.84V DDR2 5-5-5-18 latency memory Model (TWIN2X4096-6400C5DHX). http://www.newegg.com/Product/Product.aspx?Item=N82E16820145176&nm_mc=OTC-C173T&cm_mmc=OTC-C173T-_-Memory+(Desktop+Memory)-_-Corsair+(XMS+Series)-_-20145176
I have placed the memory in the configuration listed with the manual (DDR2_1 and DDR2_3 both with and without the Turbo cards) and have reseated the items several times.
I also use a 8800GTS video card and two SATA 500MB hard drives and an Artic Cooling Freezer 7 Pro fan on the CPU.
In all instances the computer will initially boot, the motherboard would shut down and then reboot with the D-LED Memory/Detection Test showing a "Memory Module Damaged Or Installed Improperly" LED configuration and the motherboard will remain in standby mode. I can't even get into the startup screen/BIOS configuration as the board remains in standby mode thereafter.
I should also note that I am using a port over power supply from my XP3600+ which is a Linkworld LPG2-630W 20+4 Pin 3Fan ATX Power Supply

Though I don't know if using such a power supply would have the effect I have seen so early in the boot up process.
According to the Corsair web page:

If you look at some of the motherboards tested the MSI P35 Platinum was tested with the TWIN2X2048-6400C4DHX version successfully.
Has anyone encountered this problem before with the motherboard/memory matchup? Any suggestions? Thanks...
BTW the case is a Thermaltake Xaser III supertower with about 7 fans...
