Memory issue - 1 stick works,other does not - RMA did not find erros

[ramless]

Hi

Thank you for your expert knowledge to anyone that awnsers. I've got a weird situation with my RAM sticks (A dual channel kit).

I've purchased 2 memory sticks from OCZ (says Dual Channel Kit so I guess they are paired). The memory is x2 2gb PC3-10666 with a latency of 9-9-9-26 and 1.7V, and one of the sticks shows bad bits in memtest86+, I've done some tests with juts one stick, the bad one shows errors when placed in any of the 4 slots on the motherboard, while the other stick shows error free passes on all slots of the motherboard, so I thought this was clearly a memory issue with one of the sticks, but the computer store says otherwise, here are just screenshots of my tests with errors:

Memory 1 slot A1 -> same as below, sry lost this image
Memory 1 slot A2 -> http://img692.imageshack.us/img692/4886/mem1busa2.jpg

Memory 2 slot B1 -> http://img704.imageshack.us/img704/6448/mem2busb1.jpg

Now the problem is that I've sent them in for checks/replacement (?) and the store checked them and said they passed their tests in MemTest86+. They said that these MemTest86+ results are not enough and that it would be an incompatibility with my motherboard. The system is not overclocked and the motherboard spec. says that it will work with PC3-10666. So I'm wondering, how could it be possible that my tests clearly show errors with one of the sticks, but not the other, when they are paired for a dual-channel kit, and the store could not find any issue?, how can I argue against their error free tests? Or am I just doing something wrong and the motherboard could be incompatible with one of the sticks?.

Here is my configuration in the BIOS for the memory (I am also using the latest BIOS):

I do not have another motherboard to test the sticks in, though I will probably get new RAM before sending these in for RMA.

The motherboard is an ASUS M4A785TD-M EVO, on the ASUS, in the memory compatibility list for the motherboard they mention 2 OCZ memory sticks (product number OCZ3P13334GK and OCZ3P13334GK), those are both with a latency of 7-7-7-20 so my memory is not listed, mine is OCZ3G13334GK with a latency of 9-9-9-20. But I think it is strange that only one stick works, if there was an incompatibility then I assume that both sticks either would work or not work.

Thank you

I don't know why the store is refusing to exchange those sticks.
You have solid proof they are not working.
See the manager.
File a complaint with the Better Business Bureau.

Thanks for the replies, I read up more on my rights as a consumer ( I live in Sweden ), and I do have the right to get them replaced at least.

I was just asking here to be sure that I am not missing something or doing something wrong. Of it such an incompatibility is possible.

I will get the sticks replaced in one way of another.

I should also add that I did not purchase them from OCZ, in my first post "I've purchased 2 memory sticks from OCZ " I meant that they are branded as OCZ, I can now not delete or edit this thread.
