OCZ Timings

[Emu9x]

Hi. I have the OCZ400512ELPE Dual Channel Kit after 2 days of messing with my pc trying to stop errors in memtest i finally found out my problem, the timing my memory supports is 2-3-2-5 but when these timing are enabled i get errors in memtest! but when i set my timings to 2-3-3-5 everything is fine! if anybody knows what i can try or do to get my timings to work at 2-3-2-5 please let me know! i have adjusted voltage etc, and my system isn't overclocked my htt is at 4x! and my memory is at 200.

Thanks.

what volts are you giving it?

[Emu9x]

2.65v at the moment, i have gone to 2.75, but didn't make a difference!

The memory you using is 2-3-2-5 with intel boards. For amd tras(5) works better at 6-7. They max at about 225mhz and don't like above 2.8V.

[G-Code]

You could try setting the DDR Output driving to "weak" and to DDR drive strength to 50%.

 

Other than that you will not find much if any difference in running 2,3,3,5 to 2,3,2,5.
