Memtest results on new RAM?

I recently purchased 8GB of new RAM [1] for my main computer, and saw memtest 4.0 might be a good tool to test the quality of the RAM. I ran the utility for a little over 18 hours, and then manually stopped it. If I'm reading the report right, it said there were approximately 1560832 errors. See screenshot.

This means bad RAM right? Can I tell from the report which slot, or do I need to run the test one by one for each of the 4 DIMMs?

[1] G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-4GBPK - Retail

I have the voltage set to 2.1v, and have applied the G.SKILL recommended settings for my motherboard (Gigabyte EP45-UD3P 1.6). Here are the results of the tests I ran this evening:

Single DIMM in slot 1, no error
Single DIMM in slot 2, no errors
Single DIMM in slot 3, no errors
Single DIMM in slot 4, no errors
DIMMs in slots 2 and 4, no errors
DIMMs in slots 1 and 3, errors
DIMMS in slots 1, 2, 3 and 4, errors

Any thoughts on the results?

I think I read something about slots 1 and 3 on this board as well, but I can't remember right now.
The other weird thing is I have no system instability. If it wasn't for the memtest results, I wouldn't think there were any issues.

@garycase: I'll try your test ideas soon. I've had enough for tonight. :)

Since the board uses unbuffered RAM, I wouldn't recommend using more than 2 modules anyway -- I'd simply install modules in slots 2 & 4 and run with 4GB.

... or, if you really want 8GB, buy 2 4GB modules and put those in slots 2 & 4.
(your motherboard supports 4GB modules) ==> something like this:
