 Topic: Asrock Z370 K6 Gaming RAM SLOT issuePosted: 23 Feb 2018 at 11:31pm |

Hi!
I just bought the Asrock Z370K6 i use the Intel Core i5-8600K, 6x 3.60GHz, tray (CM8068403358508) cpu and the new G.Skill Trident Z RGB DIMM 16GB, DDR4-4133, CL17-17-17-37 (F4-4133C17D-16GTZR)Kit It seems the G.Skill Kit is limited due to B2 slot. Only Slot A2 supports the XMP Profile See following Setups: 1st Setup I used Channel A2 B2 2 DIMM. I wasn't able to run the memory above 4000mhz with timings 17-17-17-37 2nd Setup Channel A1 B1 2 DIMM. The max. possible speed with the XMP Profile was 3066mhz 3rd Setup Single Channel A1 1 Dimm and I also reached max 3066mhz 4th Setup Single Channel B1 1 Dimm with the same result 3066mhz 5th Setup Single Channel A2 1 Dimm and finally i reached the 4133mhz with 17-17-17-37 (PrimeStable) 6th Setup Single Channel B2 1 Dimm max possible speed 4000mhz So my Kit is limited due to B2 slot. Can you tell me a solution? Are there maybe bios settings i can do to increase the B2 Performance? I really like this board and the features and i really dont want to exchange it. |

If your question is why won't it run at 4133, that is not guaranteed as it is an OC that relies on mostly the Silicon Lottery to be able to do? |

as i wrote.... both ram modules run @ 4133mhz! with the specified timings but only on A2 slot. So the Ram Module is pretty fine.
A1 3066 B1 3066 A2 4133 B2 4000 i tried each slot with both modules in all variations. So the Ram is OK. It's motherboard issue Edited by MovingMike - 24 Feb 2018 at 12:01am |

 Iam happy.You can find it in the OC Tweaker 4th Timings. I changed the standard value (auto=4) to 5. Now the modules run at 4.133mhz at specified Timings (A2 B2 socket). I downvolted the kit to 1.35v. primestable for 1 hour now. So the kit runs nicely on this board but i ve no clue what the IO-L Init Value does. even 4.266mhz boot so far 1.4v |

I, like many other users I've seen, have the issue where we can't overclock on the A1/B1 channels, just stuck at 2133MHz. I'm running the 3200MHz version of the TridentZ ram you have. Changing the IO-L Init value didn't work for me.
Could you explain the steps you took and what values you modified in the UEFI?
