Step by step to determine what IC you have:
1) Set DRAM Frequency to 1600MHz and set DRAM Voltage to 1.20v
2) Set CAS# Latency to 9, Write to Read Delay L to 3 and DRAM Write Latency to 9 and Save and Exit.
3) If it boots up then you have MICRON IC DRAM, IF it fails to boot, then move onto step 4.
4) Set DRAM Frequency to 1600MHz and set DRAM Voltage to 1.20v.
5) Set REF Cycle Time to 140 and Save and Exit.
6) If it boots up then you have HYNIX IC DRAM, IF it fails to boot, then you have SAMSUNG IC DRAM.
