TW3X4G1600C9D w/ MSI 790FX-GD70 Phenom II 945

I'm having problems getting this combo to work without freezing. The mobo and ram are listed as compatible by Corsair.

 

I am on a fresh install of Vista 32 on new hardware. PSU is a brand new Corsair single rail 60+ amp 750w workhorse.

 

In order to get the system stable enough to install without a hitch, I have run with stock timings manually set (actually better than the auto timings), 2T, not in dual channel mode, at stock (1.8) voltage with +.2v on NB and SB, at 1066 clock. No swizzle, no gang, no OC on the FSB or anywhere else.

 

I was able to get through service pack 2 with only 2 freezes. Arguably, the system was more stable before SP 2. No freeze occurred actually during an upgrade. One boot it might freeze hitting the windows icon (old "start" button). The next boot it might not freeze at all: install and reboot fine.

 

The system will sit at the desktop happy as a clam all day long but will freeze more often than not as soon as I try to do anything or within 2 minutes of starting anything.

 

Running the system in dual channel is worse.

 

Running the system one stick at a time is no better.

 

Running 1.9v on the memory does not resolve the issue although it may help prolong the inevitable sometimes.

 

Temp is not a problem. In the prior windows install, I had similar issues but the OS install itself was suspect so I re-installed. At that time, I loaded prime-95 from a flash drive (browsing is highly crash prone), and ran it for two or three hours after running a couple hours of memtest. 44 was the max temp. Open a browser and boom, freeze.

 

OS is fully updated. Drivers are fully updated. BIOS is v 1.4, there is a 1.5 out but it's changes do not apply to any of my issues.

 

Please throw some ideas out; it's been nearly 5 days since I put this problem child together.

Please test the modules one at a time with http://www.memtest.org and I would load setup defaults and then set the Voltage that is printed on the modules label and set the memory frequency at DDR1333 Max and disable Legacy USB and test the modules one at a time with http://www.memtest.org to see if it might be a module causing the problem. If they both pass then run one for one day and then the other the next if it is a modules when you run them one at a time it will show when tested one up.

OK, starting memtest now with a single stick, BIOS at defaults including auto on all voltages but memory set to 1.8v per the label, all timings at auto at 2T and 1066 clock. Legacy USB cannot be disabled because I do not have an internal DVD player to use. However, based on my reading, that will only matter if a stick fails memtest. If one passes and one fails, that will only matter practically if I can show stability with the stick that passes and not with the one that fails. Right?

I have not seen the legacy USB be an issue on MSI MB's so dont worry about it.

I have the same system that I just built. The Corsair Dominator TW3X4G1600C9D memory is running at 1066. How do I get it to run at 1600? Any help would be appreciated.

Thanks.
