The RipjawsV kit I used for testing G.Skill rate for 2T anyway but I always aim for 1T stability first. On the K4 1T stability @ 3200 is just not possible at least right now but the kit did pass 17 hours of HCI @ 3066 14-14-14-25 1T. To get 3200 stable switching to 2T is necessary with minor tweaks to the timings; 16-15-15-15-35, tMAW.MAC 1, tRC 75, Gear Down Disabled, AM4 Advanced Boot Training Disabled. It's probably not necessary to switch tMAW.MAC to 1 but in my testing it did add a small but noticeable improvement to stability. I also did a quick 3333MHz benchmark test with the same timings in AIDA64. Heres a quick chart I knocked up comparing the semi stable 3200 results from the K4 review, 100% stable 3200 2T results and the quick 3333 bench run;



For sure you have to fight with the K4 a lot more than you should have to right now to get 3200 running smoothly but once you find the magic number its all smooth sailing with even some OC wiggle room .
