what memory kit do you recommend? I need 32GB, looking at 2x16GB samsung b-die kits, is bdie still preferred?

The new QVL for the C8H Wifi (my board) has some 2x16GB Team modules rated for 3600 at 14-15-15-35 and 1.45V. It's Samsung memory and looks like B-die. As to whether B-die is still the most desirable, I can't comment.

Hi
I hasve the same issues, but its not your Corsair memory.
The beta BIOS for the crosshair and the new 5000 Ryzens is not working peoperly.
I got the memory running at 3600 DOCP profile, but then you get hundrets of WHEA errors in Wondows, and all is buggy.
I hope Asus supplies a fixed BIOS ASAP

not sure why but its going much better now, before (with Ryzen 3900x) i was max able to run 3733@dram calculator settings

after I installed 5900x it wasn't even stable at stock XMP

removed 2 sticks and was able to get to 3800@dram calculator settings with 2 sticks, put the other to stick in and now I'm running 3800 with 4 sticks, still testing stability, its been running prime95 large FFT's for an hour

update, its back to utter instabililty was good for 1-2 days, now same settings are completely unstable, something is very off with this beta bios

Sorry missed this. G.skill NEO branded. b-die is best to overclock or play with but set and forget any of the NEO Range would be fine in size you want.

2x16 DDR4@3600 would be ideal choice.

5000 series chips with the right memory modules should be able to hit 1900FCLK and possibly higher. You may need to try as much as 1.15v VSOC depending on the CPU sample.


Have not experienced any idle instablity or boost issues on the 5950X personally.

I tried some b-die memory and all the bioses (2311/2402/2502) are giving me the same result,
after bios flash/bios clear/load defaults, it appear stable for first few reboots/hours, DOCP works fine, some mild mem OC/memory timing also works fine.

then ill get a reboot in windows and fails to boot back to windows with same memory settings going back to stock DOCP will not boot, only very relaxed timins (auto 22-22-22-52) at 3200 or slower will post again to windows

reflashing the bios/bios clear/load defaults and machine is back to normal, I can enable DOCP and even oc again

to me it looks like some (hidden?) setting is set to some incorrect value or these new bios'es are very immature
CPU SOC voltage on auto sometimes sets to 0.98V, sometimes ~1.08V and seen it set to ~1.15

Memory im testing is
Corsair CMK16GX4M2Z3600C18 (4x8, also tried 2x8) Micron E-die
T-force TDPPD432G3600HC16GDC01 (2x16GB) Samsung B-die
same results with both

Haven't killed any zombies in 2 days tryna set this amd **** up stable

Holy frack

Bios 2702 seems better to me, its not failing randomly and then no bios settings will post to windows like the other "new" bioses

I'm able to run at DOCP atleast now, although the bios doesnt seem to like DRAM voltage higher than ~1.39V, then it fails to post to Windows

hoping these issues will be fixed with the new AGESA thats coming

My b-die on that bios is running 1.5v natively@3800
