Anyone with 3200C14 b-die ram got good overclocks with 3900x?
I have 3200MhzCL14 B-die RAM but not a 3900x,
But I can assure you even I am able to get up to 3733MhzCL16 OC, however, it does not perform better than my 3600MhzCL14 OC.

Also really looking forward to trying out the tool on my 3900x & x570!
The Gygabyte boards seem to have this hideous bug where if the fabric is running at 1800mhz there is a very high idle watts, like 50w, and below is 25w:
What's worse is this seems to also affect performance, if I run fabric+memory at 3733 my cinebench scores actually drop a few hundred points =/
So I'm downclocking my 3600 mem to 3533 (fabric 1766) but i have no clue what timings are best for that, would love to tighten them up with the calc!
Thanks for your hard work! It's really appreciated!

I'm ready to try a new DRAM calc with my 3900X
So far my 64Gb Hynix A die that was working at 3200Mhz with my 1800X won't work with the new CPU in the same board. I'm sure is just a couple details but is hard to tell which one. Also we need to wait a bit for the BIOSes to mature some more.

I never seen IF clock show up on HWinfo64 before, Look like I set IF correctly it's show up on screen.
See Ryzen Master and HWinfo64 match it.
This ram C-die CJR at 16 19 19 19 36, I can't use currently dram calc 1.5.1 do not work for over 3600.
I borrow main timings from the link at

You running 4x8GB? What was the key to getting GDM disabled and stable?
I think it was the combination of procODT & setting the CAD Bus Drive Strength correct. Mostly thanks to the CAD Bus Drive Strength.
I needed to have 60Ohm for ClkDrvStrength to stabilize the setting to not return errors. Geardownmode enable only need it [auto/24Ohm]
This is usually motherboard/memory specific so your mileage varies.

I'll bite with a interim result of stability & AIDA64 as I test various settings here and there. It was a little more trouble getting GeardownMode: "Disabled" working than I thought.
I haven't really begun lowering timings yet as I was nailing away the stability issue for GDM disabled.
I can agree on I found no use in increasing SoC voltage or the derived VDDG from it. Was causing more issues than helping.

|nolive721||for some reason the 3066Mhz with tight timing didn't show up in my post, trying again|

just starting to play with RAM Ocing so found the software here quite helpful
But it seems I am hitting the wall with the sub timings tweaking I am doing to try to improve the RAM performance being speed or latency
is there something I am doing wrong or is it jst what my CORSAIR C16 3200Mhs kit is capable of? Its Hynix MFR so I know not really the best out there but I was hoping to see some benefit beyond 3066Mhz which doesnt seem materializing
