I´m trying to get 3466c14 stable, is it still recommended to NOT use GDM enabled togethr with un-even primary timings?

Well GDM with odd CAS will usually result in the odd value being increased to an even value.

That's quite the feat oh and thx for providing us with great information and tools so far to get our dram running smoothly

@rest I tried running tRCDWR at 8 too but there wasn't even one bit of a difference for me than with tRCDWR 14 just for information.

what Ram voltage?

I tried the same timings for my ram but was not stable, BUT I think it can gain stability using 1.48v or maybe a little more Ram voltage

[Official] AMD Ryzen DDR4 24/7 Memory Stability Thread

Yesterday I read from somewhere that increase tFAW may lower VRAM voltage

So, I try on my 4 dimm

8GBx4 Hynix CJR
3466 16-22-22-22-42 60 tFAW 34
bandwidth 53k / 53k / 51k / 70.7ns
with 1.40v (lower to 1.38-1.39 cause unstable)

for new setting I just change only tFAW to 40 and use VRAM 1.38v, that's work

bandwidth drop 400-600MB/s each, that acceptable to me

both setting tested with memtest5 10cycle and GSAT 2hrs.

I also have to increase my dream voltage to 1.46 to get it somewhat stable. Problem for me are single late errors which can't be fixed with voltage.

Yeah i think i'm going to test those timings again with 1.47v at bios, later this weekend...

Hynix CJR - 3600 CL15

Got a 2700X with pretty good silicon (4GHz 1.15v, 4.2GHz 1.35v) and it also looks like the IMC is good as well.

Spoiler!


1.45v DRAM, 1.025v SOC.

Can't seem to get the timings down at all, tho I think I'm limited by my mobo (B450 Tomahawk).
