Board model: b550 extreme4
BIOS version: 1.20 CPU: r5 3600x RAM: 2x8 galax hof 3600 (@3800) Negative offset applied to cpu voltage combined with pbo is not stable anymore. For example this config was rock stable before (1.0.0.6) : cpu - offset -68mv vsoc - 1.1v/llc1 IF 1900mhz pbo - scalar 4x, autoOC 50mhz Overclocking now is pointless with this bios. |

Board model: X570 Extreme4
BIOS version: 2.80 CPU: Ryzen 5 3700X RAM: 48Gb (2x8Gb & 2x16Gb) HyperX Predator 3200 CL16 @ XMP Updated from 2.80 to 3.00 and a lot of problems with the memory speed, suddenly the memory revert to JEDEC speed of 2400Mhz when power up the system. If I enter to BIOS and enable the XMP profile@3200Mhz it works normally and can keep the profile during some time, but after some days it reverts to the 2400Mhz. I've downgraded the BIOS to the 2.80 version more than 2 weeks ago and no speed issues until today. Something happens with the 3.80 BIOS version. |

Board model: Fatal1ty B450 Gaming-ITX/ac
BIOS version: 3.50 - 3.70 - 4.10 CPU: Ryzen 7 3700x RAM: 2x8 Corsair Vengeance LPX 3600Mhz Under BIOS 3.50: From time to time the PC won't boot properly with the fans at max speed way longer than usual and all my BIOS setting will be resetted. XMP profile or setting the RAM to 3600Mhz works though. Under BIOS 3.70 or 4.10: If I use the XMP profile or set the frequency of my RAM to 3600Mhz (or any other frequency different that the default one), the PC won't boot and the fans will run at full speed (until I shut it down). |

solved thanks a lot, activate the xmp profile again and change the ram memory slots to the A2 / B2 and it works with without having to modify the voltage thanks. |

up the voltage a bit .. I have read a lot of users saying Corsair RAM sometimes needs a bit more voltage to run them .. so try 1.375v or similar. try setting memory manually to 3200 instead of XMP make sure you have memory installed in slots A2/B2 if only 2 sticks |

Board model: B550M Steel Legend
BIOS version: CPU: Ryzen 5 3600 RAM: CMW16GX4M2C3200C16 CORSAIR 3200MHZ VER 4.32 Notes: I have a problem with the ram memory, it does not let me put it at 3200MHZ speed, I activate the XMP profile and the pc turns off and the bios restarts. It only allows me to put 3000 MHZ with these memories and tried any solution? |

Board model: X570M Pro4
BIOS version: 3.00 CPU: Ryzen 5 3600X RAM: 32Gb (4x8Gb) Crucial Ballistix Sport LT 3000 CL15 @ XMP Notes: AMD CBS > NBIO Common Options > SMU Common Option > Max Voltage Offset This setting does not function on BIOS v3.00. Changing from "Auto" to "100" does not limit max boost voltage at all. The voltage, temperature and benchmark scores stay the same no matter the option chosen. I tried restoring BIOS defaults before testing it. 2.60 - Setting works with expected voltage, temperature and performance drop. 2.80 - Didn't test this BIOS version 2.90 - Setting is missing 3.00 - Setting does not work Thanks |

Board model Fatal1ty X470 Gaming K4
BIOS 4.20 CPU: Ryzen 3600 TridentZ Neo 32 GB 3600MHz CL16 Boots and runs fine with XMP settings despite board being capped at 3433MHz OC according to the user manual. I thought i was going to have to downclock this and go for tighter timings but it works fine. |

Board model: X470 Master SLI/ac
BIOS version: P4.20 CPU: Ryzen 9 3950x RAM: Crucial 16GB DDR4 SDRAM ECC Unbuffered DDR4 2666 (PC4 21300) CT16G4WFD8266 - The newer P4.10 & P4.20 versions of UEFI have lost multiple menu items including those for memory configuration. I think they were located in the CBS menu. |

Board model: Fatal1ty AB350 Gaming-ITX/ac
BIOS version: 6.60 CPU: Ryzen 5 1600 RAM: G.Skill Flare X 16 GB 3200MHz CL14 (F4-3200C14D-16GFX) Notes: system boots up on XMP without issues. Using the Ryzen DRAM Calculator everything now seems to be fine at 3400 MHz SAFE settings (14-14-15-14-30). Earlier I had Partiot Viper Elite DDR4 2x8GB 3200MHz (PVE416G320C6KGY) on some strange Patriot chips, they didn't worked on XMP, only on 3000 MHz 14-16-16-16. G.Skill TridentZ 16GB (2x8GB) DDR4 3600MHz CL15 (F43600C15D16GTZ) bought a week ago didn't want to boot up at any configuration except 2133 MHz. I replaced them with Flare X and I am incredibly happy :) |
