Hello, I just bought a b450m pro4 and tried to OC my memory to 3600 c14. According to ryzen calculator, I should use 1.45v, but when I put that value it automatically goes back to 1.4v. Any way to use the 1.45v? I´m using BIOS 3.60. |

What CPU, memory and type you are using? I see Min 1.39, Rec 1.40, Max 1.42 from the RC for some memory, but not 1.45V! That is very high for all day use. Anyway, the b450m pro4 is not designed for such high DRAM overclocking/overvolting. 1.4V DRAM voltage is probably the limit. And there must be a reason, why this board is so cheap! ------------- Asrock Fatal1ty X370 Professional Gaming Offline Under test: MSI X570_MEG_ACE | AMD Ryzen 9 3900X | Scythe Mugen5 | 2x16GB F4-3200C14D-32GTZ@3466 | ASUS GeForce GTX 1080 Ti FE |

also the note what cpu are you using ? if its not a 3000 series your never going to get 3600cl14 anyway and even with a 3000 3600 cl14 will take a lot of tuning and some luck regarding memory type/amount/cpu memory controller and quaility of power supply ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

Just checking, does your bios accept voltages to the hundredths or thousands decimal place? I have the B450 Pro4 (ATX) and I can punch in 1.365. I know that isn't the DRAM voltage you are looking for, but perhaps check that your bios can receive a setting that precise. I have tried OCing my memory up to 3533, but without success. I would get errors booting into Windows, but still, I am pretty sure I was able to enter 1.42 v for DRAM and that value would stick. You also mentioned you are on bios version 3.60. As mentioned on the website, it is recommended to not use that bios for Pinnacle, Raven, Summit or Bristol Ridge CPUs. I'm not sure which CPU you have, but keep that in mind. |
