Bf3 gameplay choppy

[shoozter]

hi guys i found out my corsair vengeance ram had some errors after i ran memtest on them so i bought the same pair earlier today. I checked everything and it came up with no errors. But when I went to go play bf3 the game play was feeling jumpy like I was lagging, i could mostly feel it when id aim down the sight. With my other ram everything was playing smooth but now its like this. any help? javascript: void(0);

specs:

i5 3570k
asrock z77 extreme4
corsair vengeance 8gb
evga gtx 660 ti
630w psu

Hmm check what speed the RAM sticks are being clocked at in BIOS. Also just try pulling them and switching around slots
