ram speed and voltage

imginy · 31 Jan 2013 at 16:58

Hi,

8 pack The highest I can get my samsung green memory with 1.65v is 2133mhz 11 11 11.

Any time I change either number to a 10 it fails even if I loosen up all my other timings. Also running my processor slower doesn't help either.

I was wondering is there any other voltages on the motherboard I need to change as the only voltage I have changed are cpu core 1.35v and ram to 1.65v and everything else is on auto.

Well run with this then!! Samsung timings slope up then flat with low TRAS. This is always the best profile for them. So 9-11-11 or 10-11-11 or 10-12-12 etc etc etc Next try tras 21 and 1T command rate then tune TRFC down to 107 or 96.
