From what I've learned which I still have a lot to learn cr1 is obviously better than cr2 but if you take a look at what my ram could hold stable from a few post above at similar voltages then the loss of using cr2 is more than offset by the speed increase using cr2. So far my testing in Aida benchmarks shows a fairly substantial increase in memory throughput and about a 3 second reduction in pi32m.

Dram, SA, and VCCIO were all set manually. I was able to reduce SA to 1.224V and VCCIO to 1.2V. Dram needed 1.5V still. Changing to 15,15,15 will boot at 1.45V same SA and VCCIO. Can't decide which I'm more comfortable running 24/7.

Still bored of waiting for TitanX Pascal, I passed a new HCI Memtest...

Seems a bit stable, doesnt it???

Would like to see it added to your list, my dear Scone!!!

That looks like an extremely low VCCIO. Does BW-E require a lower VCCIO than does HW-E, or is your chipset just good at the much lower voltage?

If I leave it auto, it gets lower indeed, to 1.02v... So I am selecting a higher value=1.05v.

Just read Raja in B-E thread and lowered cache voltage to 1.30v exactly (from 1.33v), have to check stability later...

Welp, the quad channel RAM would not operate at 14-14-14-34-2T either regardless of settings. So, my chip just doesn't like those timings, at least for 3200MHz. It almost forces me to go to 3333MHz since I can run CL16 with 1T timings there without issue, which is more reasonable.

Try 14-15-14-34-1T ... worked for me and I also had a hard time with 14-14-14 thumb.gif

Going from 14 to 15 with tRCD would allow me to drop to 1T perhaps?

Exactly!

CPU core: 4.843
Cache: 4.843
Vcore: 1.44V
Dram: 1.49V
VCCIO: 1.224V
SA: 1.25V

Tested stable with 4 passes of memtest. I plan to download and install Gsat to further test and submit. I think this will be my 24/7 settings. What do you guys think?
