Vento, it seems that Elpida straps from the RX500 series do suffer from the same thing.
For some reason, r_timings_rx doesnt calculate properly the TRP_RDA.
For example, this is the stock 2000Mhz strap:
The thing that you need to look out for in that strap is:
Those are the values for TRP_RDA, it consists of 2 bits.
The first bit (as seen right now), seems to be the one causing the issues. It has 4 values - 0 to 3 cycles in Hexa result to +16,32,48, and at 4 it reaches 64 and gets zeroed again.
Or just copy/pasted out of my notes:
1st bit X, 2nd Y.
XY , Xe[0,48] at 0,1,2,3,4 and so on. 0 = 0, 1 = 16, 64 = 0, 40hex=0dec, 3F = 63. Ye[all]. 2xhexa bits (pair) limitation.
No idea how only i see the issue
