Just build a new rig

[Craigv]

FX-8120 cpu
8 GB Ram
ASROCK 970DE3U3S3 motherboard
Gigabyte HD7770 Radeon Video card
Barracuda 2TB HD
Windows 7 professional installed no updates yet
Uploaded driver disk with motherboard and some of the utilities
Haven't upgraded the vido drivers

Upgraded the bios to 1.2
Locking up on memtest86+ ver 4.1 locked up twice so far running it for 3rd time got as far as 43% pass at test #7
Also locks up on randomly in windows

The trouble with any build is that you may not have any components that are "known good," so issues like this can be hard to troubleshoot. I've had a difficult time finding memory that works well with AMD motherboards, so I tend to only use modules that have been validated by the motherboard's manufacturer. Asrock has a list for your specific motherboard:
http://www.asrock.com/mb/memory.us.asp?Model=970DE3/U3S3

Are your modules present on that list? If not, you just may have incompatible modules. If they are not on the list, see if you can return them and buy some modules that are on the list.

There are some other tests you can try:
Install only one memory module and try running memtest. If that module fails, move it to another slot and retry. If it still fails, repeat the same steps with the other memory module. If that module passes, you probably just have a bad memory module and should RMA it. If you can't get any memory module to pass no matter where you install it, you could have an incompatible motherboard/memory combo. You could also have a bad CPU or a bad motherboard or even a bad power supply.

If you can get both modules to pass when they are installed by themselves, then you probably have no memory problems and instead probably have either a motherboard, CPU, or power supply issue. Try reducing the operating frequency of the memory in the BIOS and see if you can get it to pass. You can also try installing both modules onto the same memory channel and see if that helps. If you have any spare parts, like a different power supply or CPU, swapping those in for testing can help to narrow things down too.

Good luck
