It depends on what you're using the memory for and whether you're overclocking or not. Generally, memory differences are only felt by extreme overclockers and those who do other things that require large/fast memory bandwidth.
That said, I think I'd take 6-8-6 over my 7-7-7 kit.
lsd, you planning on dicing these chips? I'd love to see if they can hit the 2700 that you were able to hit on those other sticks. Considering you got 2600 on such low voltage on air, I wouldn't be surprised at all.
It would be awesome if you did another 980X subzero pi run with these clocked insanely high
Will the cpu fit with this very low timings?
And i have seen somewhere sometimes that my mobo (giga x58a-ud7) has some compatibility problems with the mushkin!
What do you tell me about?
Thank you for the time
EDIT: I need pc only for hardcore gaming, unrar big files and decode some HD videos
