Until now, I had this bad RAM kit of Ripjaws4: 4x4GB (XMP:3000C15) that I've been able to OC to 3333C16@1.45V. I decided a week ago to upgrade my RAM to 32GB, but as I will probably upgrade next year to zen 3, I thought it would be better to get a 2 DIMMS kit. So on Buildzoid recommendation, I got myself a good dual rank bdie kit from G.Skill : F4-3200C14D-32GVK. I was thinking I could OC this kit to at least 3600-3800 Mhz but I can't go above 3333MHz (the next step is 3466MHz), whatever I try. I tried some of the advice here : https://community.hwbot.org/topic/147255-guide-skylake-memory-timings-on-asus-motherboards/ The above guide permited me to go from 3200 to 3333. Also tried a few things here : https://hwbot.org/newsflash/3939_xtreme_addicts_ultimate_tweaking_guide_for_b_die_memory_on_asus_max... I tried to fix most of tertiary/secondary timing, tweaking skew control, tweaking vref voltage (without any luck, because when i touch things here, i can't even boot at 3200) Of course, I tried to raise all voltages (RAM, IO, SA) Primary timing are configured as:16-20-40 But nothing worked for now, always stuck with this damn 55 code.
