How do I resolve the Northbridge errors in my 64-bit system log messages?

Limitation: The northbridge status error numbers may change slightly however this resolution applies for 64-bit architectures. This symptom has been seen in Red Hat Enterprise Linux 3 and 4.

Symptom:
Translation Look-Aside Buffer (TLB) reload causes errors with certain Linux software. In the BIOS Advanced menu, there is an option named "No Spec. TLB Reload." By default, this setting is disabled and allows TLB reload. With this default setting, errors similar to the following have been observed on systems running any 64-bit version of Red Hat Linux:

Northbridge status a60000010005001b
GART error 11
Lost an northbridge error
NB status: unrecoverable
NB error address 0000000037ff07f8
Error uncorrected

Solution:

To avoid these errors, disallow TLB reloading through the following steps:

1. Reboot the server and press the key to enter the BIOS setup. This key varies from BIOS to BIOS and maybe seen when the machine first boots up.
2. Navigate to the Advanced > Chipset Configuration BIOS menu.
3. Use the arrow keys to scroll down to the option "No Spec. TLB reload" and change its setting from Disabled to Enabled.

This will disallow TLB reloading and avoid the error message.

But,I have no this Option for ASUS RS161
