Crosshair X670e Ram EXPO problems

Good morning

unfortunately, as always with other architectures, I can not in any way make the ram work with a preset clock. (in this case EXPO)
G.Skill DDR5 PC 6000 CL30 KIT 32-GX2-TZ5N does not go beyond 5600 any setting.
if I install only one stick EXPO works but if I install 2 sticks it doesn't work and I have to go down to 5600. Any setting BSOD

what's the problem??????

Try setting UCLK=MEMCLK in the BIOS settings.

Hello, done. unfortunately nothing to do. Probably too weak processor memory control. processor returned to the sender who will send a new one. hope to be lucky

I noticed that the voltage of the ram can not go above 1.435. / bios 0705 / bios 805 do you confirm???

I'm running my ram voltage at 1.435 with ddr-5600 sticks OC'd to 6400. Bios V0805. Have you messed with any of the other tweaking settings? There are settings that will cause some instability unless you have things all dialed into place.

805 and 7950x bios I set EXPO : continue Bsod then I tried to raise soc voltage and ram voltage. No way. I raised the timings: nothing to do. EXPO1 set EXPO2: do nothing. I set load calibration ram to 5: nothing to do. In short, I managed to 5600 but no further. Now comes new processor. Hope for the best. Furthermore, when the operating system started up everything was fine but immediately afterwards for a few seconds I was struggling to get it to give any operation

I've got a 7950x as well. If you want to try my full stack of settings, I can try to type it up for you.

hello kryptek. It would be interesting to see your settings

* *thousand thanks tomorrow the new processor arrives and I will enable EXPO, if the ram does not reach the required speed I will try your configuration *
