GA-880GA-UD3H memory list (not really useful, info needs better formatting)

Your processor. No important details here, either.

PGV34G1333ELK 2x2GB kit, possibly two kits totaling 4 DIMMs.

"...and DDR3 at up to PC3-10600 (DDR3-1333) speeds. There is a catch
though - if you're running four DIMMs (to use, say, 8GB of RAM),
the supported speeds drop to PC3-8500 (DDR3-1066)"
That is a statement about the impact of bus loading on an AM# processor.
Bus loading affects the ability to run full speed. You can experiment
with this manually, to try to improve the situation. Normally, the
BIOS would make conservative choices to guarantee startup.

Check the BIOS. You can try selecting Auto for stuff, except for
the memory speed. With four DIMMs, set the memory speed to
DDR3-1066 and let the BIOS figure out what CAS to run and so on.
Then attempt to do your memory test, later booting into Windows.
It could be, the BIOS isn't setting DDR3-1066 when four
DIMMs are present.
If you want an alternative suggestion, drop down to just two
sticks, set everything to Auto, boot into Windows, run CPUZ
and verify how the BIOS set up the memory. Of course,
this won't prove the board really needs DDR3-1066 setting
when four DIMMs are present, but will at least prove you're
making progress with two sticks at DDR3-1333 (one stick per channel).
You can run two separate memory test cases then as well, testing the
first two sticks by themselves, and when they test good, testing
the second two sticks.
See the first or second line of the "Dual Channel Memory Configurations
Table" in the manual, for how to install the two DIMMs.
You may be able to verify in the BIOS, what speed is being used
when either two or four DIMMs is present. On my current motherboard,
it reports during the POST, whether dual channel is selected,
the speed, the memory quantity. You can use the Pause key on
the keyboard, to make that stand still, if you wish to read it
at your leisure.
I don't like booting Windows, until the memory has been tested.
I use memtest86+ from memtest.org to do the testing. (Scroll half
way down the web page, to find the downloads.) Once the
memory passes and no stuck-at faults are found, then I try
booting into Windows. Passing memtest86+ is not an acceptance
test. You should use a stress tester such as Prime95 for that.
A stress tester does a better job of uncovering soft or
transient faults. Soft faults may not repeat at the same
address location, each time you test.
