So i have PRO Z790-A WIFI DDR4 & was wondering if there is a way to check the rest of the RTL & IO-Ls on that board ??? A program, program version or a tool....? AsRock Timing Configurator is not enough.
The board lacks some useful options present in other brands motherboards of the same tier. I hope the future BIOS updates fix that. Relying only on training is not enough. ASUS have them for ex.

Anyone?

As far as I know, io-l options didn`t exist since Intel 6 series, may I know which ASUS Motherboard(intel 7xx) have IO-L option?

I just upgraded from 10700k. It has IOLs. 7th -9th gen also have them for sure. BUt you might be right about RaptorLake, I really dont know. But Im sure there are more options than just RTL Init Values. Offsets for ex.
Being able to control the IOL Offsets gives me more control (often times I can fix instability when aim for low latency). Now I have only RTL Init Values & Im pretty sure there is the cause of errors Im getting. I used the same RAM Sticks on 4 different boards. I have to rely on RoundTripLatency training which doesnt really help.

PS: The funny thing is my neighbor got the same board & CPU as me & on his board that kit is stable on the same timings/settings so Im assuming maybe one of my mem. controllers is possibly worse or Bios/Microcode versions.

Im pretty sure there are IOLs since there are RTLs. This is still DDR4. If you know a reason why they are hidden thats a different thing.
