The model number of the MSI motherboard and the exact spec of the RAM
might have been helpful. Some motherboards are VERY picky about the
type and speed of RAM that they use. On the borderline devices, a
given SDRAM stick will barely work in one slot, and fail in others.
You might be dealing with such borderline situations. Numbers please.


Sorry about the delay in getting back to you on this. I'm not
experienced with component specs, so this may not even be enough to go
on, but the only info on the boxes is:

motherboard: MSI X58 Pro-E
RAM: Corsair "Dominator" DDR3. Using 3x 2GB sticks.


Are you overclocking the CPU speed?
What is the speed rating of the DDR3 RAM? It should be PC3-?????

Corsair "Dominator" RAM series is the favored RAM for overclocking
adventures. They even advertise it.
http://www.corsair.com/memory/dominator.html As I recall, when I tore
apart one of their DDR2 sticks, it's Intel chips, with a useless
aluminum heat sink attached mostly for aesthetics. The sticks are then
selected for speeds somewhat above the DDR3 specification. Note that
similar looking sticks are bin sorted by speed. You may be using
rejects, or a mix of speeds. Little wonder you're having fallout. If
overclocked, don't be surprised if you get complaints of hangs and
spontaneous reboots in the field. If running a speed mix, you could be
seeing combinations that won't work.

I've had limited experience with DDR3 motherboards, and none with the
above combination. I have had some experience with PIII and P4 vintage
MSI (MicroStar International) motherboards and find them to be near the
low end in quality. However, this board:
http://www.msi.com/product/mb/X58-Pro-E.html uses all polymer
electrolytic capacitors, so there a good chance it will survive the
warranty period. However, that's no indication layout and design
quality, neither of which MSI is known for. I can't tell from the
"detailed" specs if overclocking is supported. It proclaims:
Supports six unbuffered DIMM of 1.5 Volt DDR3 800/1066/1333*/1600*
(OC) DRAM, 24GB Max
I'll assume that the Corsair RAM is running at 1600MT/s, which is well
under their tested speed, so it should work. However, if the
motherboard is set overlocked, it might not.


Jeff here is my current machine:

Corsair XMS3 4GB PC12800 DDR3 Dual Channel 1600Mhz
AMD Phenom II X4 955 Black Edition AM3
ASUS M4A78T-E AMD 790GX Socket AM3
ULTRA LS600 600W ATX POWER SUPPLY

Built in July 2010. Ran for a month at standard CPU clock.
Upped 3.2 to 4 ghz in August 2010

Dual boot Mandriva 2010 Power Pack server kernel
# uname -r
2.6.31.13-server-1mnb

Windows 7 Ultimate.

Zero problems/anomalies. Rarely use the Windows 7 anymore but had
same stability in Manddriva 2010 and Win 7.

Asus M4A78T-E is the overclocker's choice because of all the
timing and core syncing features.
