I assume you are only using the Advanced option of the UEFI/BIOS? If so, the Main screen is display only, there is no way to select any options on the Main screen. I assume you are selecting a slot with that option on the upper left of the SPD screen?

Very strange that CPU-Z does not show any memory in the slots. Are you seeing the full 16GB shown in CPU-Z? Win10's CMD's 'wmic memorychip get speed' shows 2133MHzĬpu-Z tab Memory shows DRAM Frequency 1077Mhz, NB Frequency 4242MHz, 15-15-15-36Ĭpu-Z tab SPD does not show any RAM at all on any of the slots.ĭo you guys have any idea what I am doing wrong with the RAM? What can I try to get the promised 3200MHz or even just 3000MHz?įirst, your memory should be in the A2 and B2 slots. I selected 'Profile 1' in the main menu, then went to 'Advanced -> OC Tweaker' and again selected XMP2.0į-Stream Tuning: DRAM voltage shows 1.360V, and that the RAM is mounted in A1 & B1 (slot 1 and 3) Now I went into the UFEI to increase the RAM speed to 3200MHz by using the XMP2.0 Profile. The RAM is listed as compatible for this board on the GSkill page. i7 7700k, using provided auto-OC from the UFEI to 4.8GHz (shows x45 CPU ratio in F-Stream Tuning). ASRock Z270 Gaming K6 on the latest 2.10 bios, XMP switch to 'auto', Fast Boot enabled.

Please bare with me not having a lot of background knowledge, I am a newbie regarding overclocking.

I have run into issues with my DDR4 bus speed on the ASRock Z270 Gaming K6 - it's not increasing beyond 2133MHz.
