That was asked and answered, truthfully and honestly, while I do prefer GSkill DRAM and make no bones about it the original question was which was better a Corsair 1600/7 set or a GSkill 1866/9 - my response is here - the Corsair.
Then it was changed to 1600/9 vs 1866/9 (Gskill) and I again responded the 1866/9 is the better sticks in this case (the GSkill)...(and I've had those sticks on that mobo, I may not build on MSI (my choice due to poor QC), but I get plenty of opportunities to work on them for problems, upgrades, etc.
Then let's see, you jump in claiming GSkill doesn't work well on MSI, which isn't true and isn't the fault of GSkill sticks - and point to a ridiculous suggestion from the MSI forums. To which I pointed out that MSI is slow on their BIOS updates - and that causes compatibility problems, also that the MSI forums are simply pro Corsair...
I see you have a MSI mobo, are you running the latest BIOS? If you look at your mobos BIOS updates, there are a number of them that show increase DRAM stability, and even one for RC Code update, that's a biggie, when they have a bad Memory Reference Code update, that's basically the coding where the BIOS looks at the DRAM and tries to figure out how to get the sticks set up....that is definitely a BIOS problem, you don't see it listed very often
