How do I set RAM Timings

Hello guys, I'm experiencing a problem with my RAM. I had Hynix 4 GB DDR3 1333 MHz CL9 and it worked fine. Recently I got Cruical 8 GB DDR3 1600 Mhz CL13 and decided to put it in another slot to see if it works. I managed to boot and computer worked fine for couple of minutes and it froze. This happened all the time, so I had to restart it manualy. I went to BIOS and tried changing some of RAM timing values, and managed to make system stable by setting RAM multiplier to 1066 MHz instead of 1333 MHz but now my memory has frequency of only 1066 MHz. Can you tell me is there any possibility to have stable system on 1333 Mhz by changing certain values?

My specs are:
Intel Celeron G1620
Biostar H61MGV3

With these settings I have stable system:

14087276_10208853385104992_2010536291_o.jpg


These are timings of Hynix 4 GB 1333 MHz RAM:

These are timings of Crucial 8 GB 1600 MHz RAM:

Thank you in advance :)

Mixing different types of ram is a bad idea.
They should be the same speed, same capacity, same brand, same CAS Latency... That's why you're having issues.

I know that, but I never had any problems with mixing it, faster RAM would work on frequency of lower RAM. In this case Crucial RAM should work on 1333 MHz, but it doesn't. The system is stable only when I set frequency to 1066 Mhz, but that is too slow.
