Hi, From my personal use/experience the following occurs. BIOS v4.7 and Beta v4.81 = Disabling CPU SMT creates a bug that will not allow ACPI Configuration --> Suspend to RAM --> Auto to function correctly. It continually reverts to Disabled. (BIOS v.4.81 I found highly unstable and have reverted to v4.7 for general use.) In both scenarios, all other system settings are at 'UEFI Default' except DRAM Voltage which is appropriately set as per manufacturer recommendation. The end result is within Windows OS the 'Sleep' function is unavailable / not working. My hardware: AMD Ryzen 1600 Fatal1ty X370 Gaming X Corsair Vengeance LPX 8GB (2x4) Windows 10 64-bit 1803 (although this is BIOS bug, I don't feel OS is related to problem) |

Yes I agree they should add notes if this is such the case. Your Ryzen 1600X is excellent silicon!! I can only get my 1600 to Prime95 stable 3.9Ghz @ 1.41V And my RAM is CL19 4266Mhz specs but cannot get my PC to accept anything below CAS 16 @ 3200Mhz. I input CL 15 but it boots with CL 16 ... I'm thinking that's related to silicon quality also? |
