Corsair 4x16GB - Phantom Gaming 4 XMP fail

Hello

I have these:
mbo ASROCK X570 Phantom Gaming 4, AMD X570, latest bios
cpu Ryzen 9 3900X
ram CORSAIR CMK32GX4M2D3200C16 Vengeance LPX Black 16 GB sticks
psu Corsair RM750i
gpu SAPPHIRE RX580 8G D5 Nitro+
ssd1 ADATA XPG AGAMMIXS5 1 TB M.2
ss22 ADATA SX8200 PRO ASX8200PNP-1TT-C 1 tb M.2
os win 10 pro 64

All except gpu and psu is less than 15 days old.
I do plenty of video editing and a lot of developing hi res raw photos for virtual tours, so I need a lot of ram for multitasking and preferably fast ram for obvious reasons.

Issue:
- with 2 x 16 GB sticks, XMP profile activated, mobo boots and works OK
- with 4 x 16 GB sticks, mobo doesnt boot with XMP profile activated
cpu and ddr red leds lights up.
I tried all sticks in 2x mode and all works OK, so I guess that I could rule bad stick

Questions:
Is it possible to make 4 sticks of this Corsair ram to work in XMP mode?
If not, can you recommend 4x16 gb sticks compatible with XMP?
Or should I go with 2x32 gb sticks?

I can still return my ram and get more compatible one

Thanks,
regards

ah .. so already running the 2.30 BIOS?

Hi

It seems that didnt have latest bios. I flashed it yesterday to latest one, and now I still cant set XMP profile because it wont boot into uefi, and clearing cmos is needed.

However I tried one "very clever trick": changed ram freq from auto to 3200 and voila: it booted into windows and system reported 3200 mhz ram.

I tried 3 diff ram/system benchmarks and they reported approx 15% better speed when changed auto to manual freq.

However after setting 3200 freq, Windows doesn't always boot from cold start. SOmetimes it start, sometimes it just hangs before displaying asrock boot logo.

When it hangs before boot logo, sometimes pressing reset button reboots into windows normally and sometimes it goes into bios boot loop few times before it boots into windows.

After it boots into windows I can work normally and do all kind of stresses without crashing.

I guess that UEFI thinks that system is on the edge of stability so it goes into learning mode.

I guess that if I lower the freq a bit, or change some other settings it would boot normally every time, but I need to find a time to get correct settings, because before this configuration I never went into details about ram, cpu or gpu OC, I only used manufacturer's fool proof utilities with presets for that.

My last two cpus were q9550 (had it 5 years) and 4700k (had it 6 years) and I didn't need to fiddle much with those.

Thanks for your inputs.

@Krx, another limit,

officially supported criteria for me is 2400mhz,

but now I run 3133mhz, overclocked the IMC a lot, although ram run high, but CPU overclock cannot achieve 3.8ghz anymore, only 3.65ghz, at 3.7ghz game will crash but not OS.

before 3133mhz, I used to run is 2933mhz, also overclocked the IMC but not as much, but CPU can overclock to 3.8ghz and game no crash.

There's many parameters that affects each other, gotto consider them too.

glad you got it figured out . .and I hope that's 1.35v and not 3.5v
