Purely performance based I would go the F4-3200C14D-32GTZR or some F4-3600C16D-32GTZR from what I have seen folks around here saying.
I don't however have any personal experience
Edit: Neither of which is on your QVL

I started setting tRCD/tRP below cas when I noticed in aida 64/hwfino/cpu-z that there were different jedec profiles that looked offbeat with those timings wit.

In my perception its like this for example:

14-14-14>14-15-15>15-14-14 >15-15-15

If you can do straight 15 but can't do straight 14, try in between like 14-15-15 or 15-14-14.

I think your translator is broken

Imprezzion Not many controllers and chips are capable of it. I can technically run 4000 16-15-15-28-280 but it isn't very stable and needs a LOT of voltage. I prefer 4200 16-17-17-28-280-2T which is a lot easier and doesn't really have any worse latency so..

B-die and a good memory controller.
I can run from 3200mhz 14-13-13 to 4000mhz 17-16-16 (1.35v).

Timings and "Rules":

Primary Timings:

CL: Start with a safe frequency/CL combination and adjust from there.
tRCD/tRP: Try 0-2 above CL (Samsung B-die) or 1-5 above CL (other ICs).
tRAS: CL + tRCD + tRTP (Source) or CL + tRCD + 2 (Source and Diagram). Min: 28. (Source: ASRock UEFI description)
CR: Try 1, otherwise leave at 2.

If you follow a guide like the one in my sig first you can then tighten up tRFC and raise tREFI if desired to get better aida scores
That guide has been printed by me and saved in my favorites! The guy you quoted is running my memory but only two of them I think anyway.. This is what I'm running right now and still working on tweaking at the moment.

davidm71 Hi,

Been a while since ran Memtest but got Memtest HCL with Memtest Launcher and noticed a couple things not sure about:

1. Auto selects 2 instances at 1024 Ram to test (512 per instance)
2. Gives a message that PID {number} is using 512 shared memory and 512 private memory

Anyone notice that as well?

Help please.

Thanks
