Oh my, an update. Yay! \^__^/ Let's see if I can install it without issues... Edit: update completed. First thing I've noticed is I can't find the menu entry to configure the "RAM training attempts" that was available on the 4.51D beta version. Not a big deal.

Unfortunately still the major error has not been fixed (and probably all ASRock AM4 boards are affected with this). When trying to load a saved profile BIOS screen freezes. It is unbelievable that such a basic thing does not work from the beginning of the product release...

Ok, I did also test the new UEFI. The new AMD Microcode makes a big difference so now you can actually game on the 2400g with stock settings. I did not test the ASRock OC for the IGP on the Main Page yet but it is nice that they included this setting. My second major issue unfortunately was not fixed. Despite metioning it in the change log the RAM frequency gets still reset to the JEDEC frequency (1018 MHzx2 in my case) instead of keeping the XMP profile. Also the UMA Mode of the IGP and all settings after that (e.g. framebuffer size) get reset. Saving a profile is also no option as the UMA Mode (under NBIO settings) is not saved to the profile. Steps to reproduce (with my Ryzen 5 2400g configuration, see signature, RAM is on QVL): - turn system on and set default settings in UEFI. Save an reboot. Result: Default RAM fequency (no XMP), Framebuffer size of 1 GB (also default). - Enter UEFI again, set XMP Profile and framebuffer size to 2 GB, save User Profile, save settings reboot. Result: XMP profile and according frequency is applied, Framebuffer size is 2 GB. - Shut down, cut wall power from PSU, wait a minute, plug power into the wall again an turn on the system. Result: Fans spin up for half a minute or so, then the system shuts down. This repeats three times. Then, the system posts normally, but both the XMP profile and the framebuffer size are reset to default values. Entering the UEFI and loading the user profile reapplies XMP settings but not IGP settings. I am really disappointed and will try to return the board. It is really a shame as the hardware is exactly what I want from an AM4 ITX board  EDIT: I played around with the RAM frequencies using the XMP profiles and it seems to me that profiles/frequencies above 3066 MHz do not stick and lead the resetting the IGP settings. The RAM does run perfectly stable with 3200 MHz but does seem to produce the behaviour on startup after cutting power. Is there any option to turn certain checks off? I think I read somewhere on this forum that there is an option to disable memory checks.

Do you mean the "memory training" that happens at boot? As I wrote above, there was an option on the (beta) FW 4.51D but I wasn't able to find it on the latest 4.70.

Yes, thats what I meant. Sorry I missed that you mentioned it. It is strange that one can stress test and use the system with XMP-3200 but not "cold boot" it after power loss. The XMP settings in the UEFI also preselect the 3200 profile.

I'm really baffled by the different behaviour of a cold boot with or without puling the power cord, at first I thought of faulty MB. In my opinion it's really strange that some BIOS parameter are still reset after a power loss...

This new bios definitely improved the "fast ram cold boot" issue. Before this bios my 2x8 GB 3000mhz Corsair ram would reset to 1066 MHz if ram frequency was above 2933mhz. Now I have no issues at 3200Mhz

Nice. I am unfortunately just really confused with my setup. Using Typhoon Burner I could read from the SPD that the G.Skill Trident Z Kit I have is using single rank Samsung b-die chips which are supposed to be the most compatible option for Ryzen. Ryzen Calculator also gives me timings on the save option which are way sharper (14-14-14-30 as V1 or 16-16-16-32 as V2) than the ones of the XMP-profile (16-18-18-38) and do not work also.

Yes I did. The only thing which I was not entirely sure about were the tRFC(2/4) values. RC gave me floating point values here and the asrock settings only allow for integers. So I tried rounding up and down and also the values from the tRFC calculator which were entirely different. Edit: And I even tried settings the values using ASRock OC (decimal) and AMD CBS (hex)
