You should increase your hashrate to 27Mhash with a simple copy of memory timings from 1500 or 1750 strap to 2000.

very interesting, thanks for sharing your elpida rom.

Straps are completely different, never use bios from internet, modify it by yourself!
Timing straps before 1375 is also different with Hynix.
https://s21.postimg.org/kc5c7qc6f/2016_09_28_203944.pngElpida : 200, 400, 800, 1000, 1250, 1375, 1425, 1500, 1625, 1750, 2000
Hynix : 400, 800, 900, 1000, 1125, 1250, 1375, 1425, 1500, 1625, 1750, 2000
Where is timing strap should I change in my rom file.. Just 1375, 1500, 1625, 1750, 2000 and leave others (200, 400, 800, 1000, 1250, 1425) with default value??
