It seems i'm gonna send them back but because all 4 stick preformed bad i dont know if i really want new sticks. I do need 4 GB. Maybe that shop only has sticks from the same batch.

I can also try normal non tracerts. But normally the tracerts should perform just as wel as the normal sticks ?

Or maybe i should be looking for one more set of TEAM Xtreem 800 MHz CL3
