I rebuilt the kernel with changing to "./linux-source-5.17.6-1/drivers/i2c/i2c-smbus.c"

line 358:
	if (slot_count > 4) {
		dev_warn(&adap->dev,
			 "Systems with more than 4 memory slots not supported yet, not instantiating SPD\n");
		return;
	}

replaced with
	if (slot_count > 8) {
		dev_warn(&adap->dev,
			 "Systems with more than 8 memory slots not supported yet, not instantiating SPD\n");
		return;
	}

and now it is written in the logs:

May 12 23:22:33 A1 kernel: [    4.094892] i801_smbus 0000:00:1f.3: SMBus using PCI interrupt
May 12 23:22:33 A1 kernel: [    4.095301] i2c i2c-0: 8/8 memory slots populated (from DMI)
