Long story short, I have my new machine up and running with a 1950X, 128GB G.SKILL kit, on a Zenith Extreme MB. I've slowly tried to get the memory somewhere close to it's rating speed (3600MHz) but I know running at full-beans is asking a bloody lot from 128GB.
I've got my eyes on at least 3000, but I'd like 3200MHz if possible, unless the timings get too silly and not worth the frequency increase.
Over the last two days I've gone from 2133MHz to 2733MHz on effectively stock settings, all stable. I can run MemTest86+, MemTest Pro (windows), and Prime95 for hours without issues (hence taking so long to move the speeds up).
To get to 2733MHz, most things were left at stock apart from giving the memory 1.25v, the RAM SoC up to 1.1v, and a little boost on the CPU voltage. I've also increased the boot RAM voltage, and the VTTDDR to correctly match half of the memory's voltage settings. I've allowed CPU, RAM, and SoC to draw up to 110% current just in case the OC requires it. None of that was *needed* for the 2733MHz, but as I'm looking at getting over that, I knew them settings were going to come into play eventually and thought to avoid errors at this stage, it wouldn't hurt setting a few things up as I believe they should be for now, or later speeds.
If I try to run 2933MHz however, the system is stable to use (browsing, games, whatever - for hours and hours), but testing the RAM shows it's clearly not 24/7 perfect. I get errors within Prime, and MemTest Pro either BSOD or gives errors instantly.
To try to help this, I've increased memory to 1.365v, SoC to 1.15v, boot RAM voltage to 1.37v, and tried loosening the timings from automatic 17-16-16-39 to 18-17-17-40 but still get errors. POST and such is fine, I just want it flawless. I use RAM caching, as well as memory-intensive tasks, so it's important it's stable.
I was hoping some RAM gurus here could maybe throw a few tips and tricks at me to try to see if I can at least get 2933MHz stable, and then I can do similar again to see if I can push further.
I know there won't be loads of people running 128GB to just give me settings to copy, but things like SoC is not something I've had to play with before in the past, but I understand with the amount of memory I'm running there's all sorts of settings that come into play which are just too much for me to read and fully understand to tweak at will.
