There is a BIOS setting called "BIOS -> AML ACPI table", which is set to "Enabled" Helptext: "Set this value to allow the ACPI BIOS to add a pointer to an OEMB table in the Root System Description Table (RSDT). Note: OEMB table is used to pass POST data to the AML code during ACPI O/S operations."
That is not related. The Linux/x86-64 NUMA code doesn't use ACPI at all.
In memory config "Bank interleaving" and "Node interleaving" are disabled.
Bank Interleaving can be enabled, just Node interleaving should be disabled. The northbridge configuration says node interleaving is enabled though. Or maybe you only have DIMMs in the slots of one CPU. It's possible that the BIOS then sets the interleaving mode, although it's pointless. It wouldn't make a difference in that case. Anyways, the performance difference is not that big so I wouldn't worry too much about it.
May be this explains, why xengine displays only 200rpms (on a Matrox G550).
No, it shouldn't impact 3d performance much.
Some problem in ACPI implementation or BIOS bug?
Nothing to do with ACPI. The memory controller is configured by the BIOS. -Andi
