Hi, I just recently got an asus g74sx and I would like to upgrade to a faster ram. I read many posts about Corsair and Kingston compatibility issues when using the 1866 with four sticks or even 2 sticks using corsair vengeance. Some were saying use the corsair with the faster timings, but less MHz and some were saying go with more mhz . Most of the posts I read were unfinished and never was able to find a definitive answer on this topic. So I figured id ask now since all the other posts I read were old and was hoping maybe these issues got resolved with either Asus putting out a newer bios update to fix them or not. I read the bios was the problem. Anyways if someone could help me with this issue I'd be much obliged. I'm looking for memory that's gonna speed it up the most as for I'm a gamer. Thanks!
