G.skill HZ Memtest Error - puzzled

[ooztuncer]

Well I was doing little bit experiments otherwise I am completely stable at 10x250 vcore:1.595 / vdimm:2.6.

What I did last night is try to use vdimm: 2.5 rather than 2.6. Here is the screen shot after 11 complete passes (almost 7 hours):




Do you think it is a "random" error? Error in test #6 in pass 3, and after that 8 more complete passes with no errors - puzzled definitely...

I left my machine for a 9-hour prime marathon - I will check it out later tonight. In the meantime, I would appreciate any comments...

BTW:
@g.skill technician: If you have some settings that is 260+ (prime stable) can you post some of them here.
