have you tried as i suggested
click xmp and then click 2666 manually it should load the xmp settings for timing and volts but keep them when you select 2666 then test it to see if its stable you also say with one stick it does 1.35 does it do this with both sticks tested alone ? if one will and one wont then thats the problem a dodgy ram stick Edited by datonyb - 07 Sep 2017 at 3:06am |

Its really odd behavior, I know.
RAM is CMK8GX4M2B3000C15I5, and i'm using the banks at slots a2 and b2. As the RAM works with 1.21v, we can say 1.35v its not enough. As I said, I tried everything, but the problem still. With 1 bank, I can set 1.35v, with two, 1.23v is the limit. The new fact is I can set 1.35v with A-,Tuning software.. I tested RAM with Memtest, Windows Memory Diagnostic, Prime Blend and Asus RealBench. PASSED. But fails with 10 seconds with AIDA64 stability. Sorry for poor text, Um using mobile phone to right.... |

Please pull the memory and re-seat it fully till both ends "click' , signalling it is seated correctly. What you describe is odd behavior. |

What model number of Corsair memory are you using, and what capacity and number of DIMMs are you using, as in GBs? Do you have a POST beep speaker installed? If so, do you hear any beeps when the board fails to POST? It sounds like your memory requires more power than the board is able to provide at 1.35V, for some reason. |

Unfortunately there is no way to change SOC voltage on ab350 pro4 and am350m pro4 (and probably other cheaper MB), I heard that those options persist in bios but hidden by asrock

Hi, thanks for reading. I bought, 2 weeks ago, an Asrock AB350 Pro 4 motherboard. My Corsair RAM isn't QVL, so I know it's not easy to get the rated 3000mhz speed. I'm running 2666 and I'm satisfied, it's enough for me. But, there's something I can't understand. DRAM voltage, at auto, runs with 1.21v. When I try to set at the rated voltage, 1.35v, mobo won't post. Same thing happens with any voltage higher than 1.23v. When I use, one bank, instead of two banks, I can increase the voltage to 1.35v. Is it normal? For me, this low voltage is making my system crash, sometimes..... Again, thanks for reading!
