Dear Sirs
My specs: CPU: Intel Core i7 8700K (no overclock) Motherboard: ASRock Z370 Extreme4 (1.80 BIOS) GPU: GIGABYTE GeForce GTX 1060 MINI OC [GV-N1060IXOC-6GD] Memory: 16Gb DDR4 3600MHz Patriot Viper 4 (PV416G360C7K) (2x8Gb KIT) SSD: Samsung SSD 750 EVO 120GB; ST1000DM003 1000GB; Power Supply: Enhance 600W [ATX-0260GA] System booted up only with one ram module, with two modules in dual channel configuration (installed A2 and B2 channel) computer couldn't boot up, even after reset the BIOS to Default Settings (clear CMOS Jamper). I have tried to set ram module alternately, they work one by one in any slot. I have tried to set memory timings manually with one ram module: - 15-15-15-36 and set DRAM Voltage to 1.35 V, and set DRAM Frequency [auto]. But after thaht computer couldn't boot up. - 15-15-15-36 and set DRAM Voltage to 1.35 V, and set DRAM Frequency [2133MHz]. But after thaht computer couldn't boot up. -17-19-19-39 and set DRAM Voltage to 1.35 V, and set DRAM Frequency [3600MHz]. But after thaht computer couldn't boot up. - tried loaded XMP Profile 1 and went to Voltage settings and set VCCIO to 1.10 and VCCSA to 1.15 , but after thaht computer couldn't boot up. Please send me the full BIOS settings. Does know the optimal voltages (VCCIO, VCCST, VCCSA) I should be using for my two modules ram type? Hopefully this can be fixed. best regards Xsafo

Vccio to 1.1V and Vccsa to 1.15 does XMP work correctly?

The 1.1v for VCCIO and 1.15 for VCCSA fixes my freezing issues. But I have another issue where my PC will randomly reboot itself when idle now..

What about VCCST and VCCPLL?leave them unchanged? (as in, will they auto adjust by themselves if VCCIO and VCCSA are changed?)

Justed tested BIOS 3.10 Z370 Extreme4 3.10 7/10/2018
Bios flashed, loaded Default Settings, loaded XMP Profile, still VCCSA and VCCIO much to high "for my system" Went back to 1,1V for both values and i'm fine again. Dont know why its so hard to fix this for asrock. Best regards flode |

I would recommend alone for security purpose, new Intel microcode including latest intel specter meltdown patches etc.

I also don't understand why ASRock is not fixing their buggy xmp voltage configurations.
I have the z370 killer sli/ac and it also has voltage setting inconsistancies that make it very difficult to troubleshoot and get the xmp values. I have used two different sets of RAM, both on the QVL list, and had issues. With one of them the xmp auto actually overclocks the bclk frequency and I had to go in and manually fix it (set it back to 100 from 103). If they don't update the bios soon to fix these issues I won't purchase an ASROCK MB again. I have built a lot of systems over the years and had just come back to using ASRock again and this was dissapointing.

I feel the same way. I don't get what is so hard to fix about changing the default xmp voltages that they can't accomplish.. If they don't fix it by the time I plan to purchase a new mobo, I'm just avoiding ASRock mobos altogether.
