Right guys, been tweaking my new g-skill Pi 2x2gb set. Taken a little while. Its rock stable at stock 1600mhz 7-7-7-18, so ive been running 10x400=4ghz with just 1.3v on my CPU prime stable and no probs. However, i would like to get around 445x9 and pump up the mem speed a bit. Been trying to get this stable at stock mem timings which is a little tricky, but looks like im getting somwhere!
Its still running now, gonna leave it another few hrs i think to make sure, but looking hopefull. Settings were:
vdimm: 2.08v
NB:1.58v
Primary timings: 7-7-7-18
Command Rate 2N
Sub timings: All auto, with the exception of...
Perf Lvl: 8
Dram clock Skew: delay 150ps
As you can see from the screenshot, I dropped the multi, but hopefully I will get vcore etc around similar voltages to what I had previously. Really loving this board now im on water, the NB, even with higher voltages doesnt go much above 40degrees when stress testing!
Performance level is a bit high for my liking (would have prefered 7) so once ive finished testing with these timings, I will try adjusting phase pull in's to get some extra performance, as well as trying higher timings with lower perf. lvl and see what gives the best result.
