Samsung Green Ram with i5 3570k

[mediamatt]

Hi,

Have an i5 3570k running stable at [email protected]
Have an Asrock Z77E-ITX Mini-ITX Board
Have Samsung Green Ram (8GB 2x4)

Prior to using this board, I was using a gigabyte matx board and I could o/c the ram to 2133mhz on 9/10/10/21/1t timings. (although couldn't get the i5 3570k to clock higher than 4.2ghz on the same 1.25v as now)

I cant for love nor money get them to be stable or even boot apart from auto everything and the max I can go is 2000mhz. Got plenty of volts , tried upto 1.6v and still no joy. The timings are 11/14/14/35/1t now

Any ideas?

Sounds like a bios issue with the sub-timings to me. Do you have a screen shot of the bios to show what timings can be adjusted. Then I can suggest some timings.

Also try 2T command rate. It may be something as simple as this.
