G.skill TridentX: 2400 Mhz is for Ivy processors (Changed title to give a better description of the subject) ... for a second time Today I received my second kit after returning the first one, that gave me constant Memtest and AIDA test errors. It's 18 GB (2x8) of 2400 Mhz Trident X ram (10-12-12-31, 1,65v) So today, before installing it on my main rig I clicked it into another computer and had to run them at 1600 Mhz. But 4x complete Memtest gave zero errors. Then I installed them on my main rig, at 2133 Mhz (maximum for Sandy Bridge) (9-12-12-31-2CR, 1,65v) and got a fantastic AIDA Memory and Cache benchmark of 23230 MB/s read and latency of 39 ns. Then I did the AIDA stress test, including memory stress. Red warning and test abortion after a few seconds!!!! Am I missing something here or is this just another case for RMA? Thx!
