Do both sticks work in A1 by themselves? Does the confirmed working stick of RAM work in A2? Is this a brand new motherboard? Double check the non-working RAM slots for debri with a magnifying glass or similar ------------- |Ryzen 5 5900|ASRock X570 Taichi-BIOS 4.60|2x16GB HyperX Predator RGB 3200@3600 1:1 IF|ASRock RX 6700XT|2 x PCIe 4.0 M.2 Drives for OS & Games|850 WTT Seasonic 80+ Titanium PSU|Noctua NH-D15| |

both of them work when put in the same slot, it is also a brand new motherboard. I only just flashed a light on the b1 and b2 slots and i havent seen any dust on both of them ------------- . |

| Are you actually trying to install RAM while the PC is running?! You do not do that. EVER! That can easily damage the RAM. You might be able to add an HDD while powered up, because of SATA PnP, but RAM is not PnP. |

try flashing the bios to latest version using only 1 stick of ram and the bios reset to defaults before flashing ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

| The RAM itself might be bad. It happened to me, recently. |
