I have this board and compared to the gigabyte ax370 board the memory seems to run at one speed lower on the asrock gaming k4 Me and my friend have various sets of ram and we have tried them on each others board.

I have this board and compared to the gigabyte ax370 board the memory seems to run at one speed lower on the asrock gaming k4 Me and my friend have various sets of ram and we have tried them on each others board.
Both boards are running the latest bios updates, current of today.
Sets tested are
Cosair LPX 3000 CMK16GX4M2B3000C15
Cosair LPX 3000 CMK16GX4M2B3000C15R
Boths sets run on gigabyte ax370 at 2666mhz XMP
On the asrock 2400mhz, with all manual settings work on bios 1.91 and 2.0
1.7 almost worked at 2666 and booted into windows when I raised volts to 1.45 on 2 times out of 6.
1.91 it never booted once.
Cosair Vengence LED CMU16GX4M2C3200C16R
This set works on both boards at 2666mhz XMP
It almost boots on the asrock gaming 4 at 2933, when i mean almost it does not go into
a rebooting cycle of 4 times before dropping to 2133 speeds and booting when set too high.
I have loosened the timings and pumped voltages to suicide levels and it still won't boot, its on the edge of working. It may have worked on a previous bios, 1.91 and 2.0 bios seem to worse.
However the gigabyte board, boots into windows if ram is set to 2933 XMP and voltage to 1.4 volts.
So in both cases you can see the asrock is one speed lower and the gigabyte and new bios make no difference, it anything it makes it worse as now sometimes i cannot get into the UEFI on boot as the memory training is doing a strange double reboot on startup which start bios 1.91 and also on 2.0
From the website asrock only claim 2933 support overclocked, while gigabyte claim 3200, which as you can see is one bin lower :D
Now all modules tested are HYNIX.
I have Samsung b-die, G-Skill amd specific memory on its way.
If anything is going to do 3200mhz on the asrock it will be that.
I am no confident though as that is above the asrocks quoted spec.
The asrock may be among the worst X370 board for memory compatibility.
