Cheers for the tips, gonna try the timing and skew things. About the skew, should i put it into delay and whats the general good value to set as a reference.
Yea its 2x2 + 2x1. No prob running 2 sticks, the prob is, i cant stand seeing 6 gigs of my ballistix ram lying around.... and they capable of doing 1200 just as my OCZ does.
hard to say whether you need advance or delay on a particular channel, since it will depend on the IC's used on the sticks. Micron IC's prefer 100+ps advance skew, Powerchips prefer neutral or close to neutral skews. Elpida can need delay skews.

Best way to figure it out is to put one stick of each in the channel you want to use, push it up to the highest frequency you can get it to post at that gives errors in Memtest86+, then adjust skew either way step by step and see if the errors in memtest increase or decrease. Best to use is test #5. If they decrease then you are getting hotter, if they increase you are getting colder. It'll be near impossible to deskew 2 completely opposite types of IC's with the RF since there is no individual slot skews.

I managed to pull this off on a P45 P5Q deluxe as it has A1/A2/B1/B2 but I dont know how much luck you'll have with only A / B, hopefully the IC's are similar in their skewness.
