4,387 -7.5x585@2.00B= 1,170 5-5-5-18 v2.28
Journeey''s start :-
Wprime (
CPU) solid as rock but Super Pi (
ram) buggered
Just to ensure that it was nothing to do with dual channel being unstble I tried 1170 at a lower
FSB , keeping same
cpu speed
4392 - 9x488@2.4b 1171 5-5-5-20
After trying a few things that didn't get me anywhere I upped the sub viltages. On all previos timings up to & including 1,150Mhz the sub voltages have been sxaled to
vdimm from :-
At
Vdimm 1.80v
Dram Termination = 0.80v
Channel A
ref = 0.80v
Channel B
Ref = 0.80v
MCH./
Dram Ref = 0.80v
In other words 44.44% of
Vdimm.
to get to 1,170 I needed to increase to 46.5% in other words 0.837 at 1.80v (or value closest to )
Interestingly I'd try using Auto for the sub voltages & didn't get the result.
So back to 7.5x585 but using the higher memory sub voltages :-
Finally
Stability
Currently not Prime stable.

George has been beating my man from Gigabyte hands down
