Have AMD got the BIOS optimized to handle higher RAM clock speeds for R7 CPUs or is the 2017-18 recommendation still true?
I've heard that Ryzen 7 don't really like RAM speeds above 3000mhz & running above this speed long-term can affect system stability because of the way the memory controllers work.
I have 3200mhz RAM & it passed MemTestx86 & the stressapptest with no errors using it's XMP timings.
So I'm wondering whether recommendations to stay to < 2933mhz is still best or whether the latest BIOS updates for AMD ComboPI 18.104.22.168abba have any impact on R7 RAM handling.
Its a question stability & performance between
•XMP Profile #1: DDR4-3200 CL16-18-18 @1.35V
•XMP Profile #2: DDR4-3000 CL15-17-17 @1.35V
My rig is :-
- Ryzen 7 1800x @ Stock clocks
- MSI B450 Tomahawk // BIOS - 7C02v1C
- HyperX Predator DDR4 16GB (2x8GB) 3200 MHz CL16 // HX432C16PB3K2/16
- RX 580
