I just wanted to share this thing that happened to me…
So basically, i ordered 2x8GB PNY Performance CL16 3200 1.35V kit and instead a CL22 3200 1.2v kit arrived, i got $12 partial refund and i unscammed myself by going CL16 and tightening subtimings yay!!
Notes:
-Can't take more than 1.35V or even 1.34 idk
-Can't OC further than 3200 MHz (even at CL18 1.35V)
-Can't go lower than 480 tRFC
-NEEDS GDM to be cool with it
The exact RAM model is MD8GSD43200-TB (i was supposed to get MD8GD4320016XR)
TL;DR: i got a CL16 3200MHz RAM Kit for $28

cl16 3200 mt/s is what my 2×16 c-die came with at default xmp. they’re running 3733 mt/s, 18-21-21-36, 240 trfc and gdm off after manual oc (I have actually tuned every setting in the timings tab). I think the only reason 3800 mt/s doesn’t work is because of my 5700x3d’s imc not being able to handle fclk higher than 1866 mhz
the issue with c-die is that the only way you really get performance out of your timings is by raising your clock speeds. I can’t raise voltage and lower my tcl, for example
also you can definitely do gdm off, but you need to adjust your voltages, resistances, setup times, etc… which you haven’t done
