P67A-GD55 - Random BSODs with varying codes

[Somewords]

Hey guys,

I'm sort of reaching the end of the line with my troubleshooting resources, so I'm hoping someone here can possibly provide me a little assistance.  As the title indicates, I'm experiencing random BSODs on a newly built system.  Below is what I have done to troubleshoot, as well as the specs.

MOBO - MSI P67A-GD55 (B3)
CPU - Intel Core i5 - PN BX80623I52500K
PSU - CORSAIR HX Series CMPSU-850HX 850W
Memory - Corsair XMS3 DDR3 1333 (2x4GB) - PN CMX8GX3M2A1333C9
HD - OCZ Vertex Series OCZSSD2-1VTX30GXXX SSD
HD - Seagate Barracuda 7200.12 ST31000528AS x2 (Raid 0)
Video - EVGA 01G-P3-1373-AR GeForce GTX 460

Updated all drivers to current revisions
Updated BIOS to latest revision
memtest86 - Over 24 hours of testing, all testing options, 10x passes - No errors
Windows Memory Tester - Over 24 hours of testing, full options - No errors
PSU Test - Checked every connection coming off of the PSU and all voltages are appropriate
Just for fun I've run the system with memory in varying slots and with varying sticks.  No dice.
superpi - I've run this up to 32m on all cores on the CPU multiple times just to see if this causes any crashes despite the CPU being at stock config.  - No errors

BSODs I have seen:
APC_INDEX_MISMATCH
MEMORY_MANAGEMENT
SYSTEM_SERVICE_EXCEPTION
dxgmms1.sys
And about 12 others that I didn't note at the time for some reason.

Other odd behavior:
After some BSODs, the system rediscovers all my USB devices that I have attached.

I've done research on the individual codes, but the solutions are like throwing darts at a dart board.  I'm suspecting at this point that I either have a bad CPU or Mobo.
Also note that nothing is overclocked.

Any thoughts or ideas?

TYVM in advance.

Recommend giving this BIOS a try (.1A0), Jack's Reply #193; https://forum-en.msi.com/index.php?topic=144655.160 If you do, please use the forum USB flasher also linked in that thread.

Followed the instructions provided with the MSI HQ updater... MemTest86 found bad RAM this time.  I think I'll go weep in a corner somewhere if that was the problem all along.

I also checked with Corsair's website after the RAM thing and the voltage they tested their RAM at is different than what is printed on the sticks themselves.  The sticks say 1.5v but Corsair says 1.6v...?  Will post if RAM was the problem.

Will post if RAM was the problem.

Please do keep the forum updated. Corsair RAM has worked flawlessly for me for years, even the B2 & the B3 6 series board. It's getting to the point it is getting harder & harder to recommend any RAM brand now days.

As an update, no crash of any sort since removing the offending RAM.  Contacted Corsair and they immediately issued me an RMA.  Blah, feel like a heel asking for help when it was something so simple.
