Braegnok Report post Posted September 20 Not knowing your full system specs, BIOS, and memory kit #,.. it's impossible to give you accurate advice on overclocking your memory. Assuming it's 1151 socket Z370 board with i7-8700K, current BIOS, and the Trident Z Royal 4000 kit is CAS latency 17-17-17-37 at 1.35V. Your going to need to manually tune that C17 4000MHz kit to run stable, using only sockets 1 and 4 as your board will not run full slots at 4000MHz. Your motherboard QVL shows only one 4000MHz configuration using two 8GB sticks of kit F4-4000C18Q-32GTZ single sided modules.

iacobescuionut Report post Posted September 23 (edited) I manage to go up to 3800Mhz in dual channel Cl17 17 17 37. I prefer to keep them on this frequency then 4000 Cl18 19 19 39 single channel. I forgot before i bought the rams to check the compatibility lol. Thanks for the replay that was helpful.Is not working at 4000 but works at 3866. Needs manually to set up frequency and with out cpu oveclocking with 1 module of ram 8G only and after that to insert second module in dual channel and works.
