Chapter 7: BIOS

Uncore Configuration
Use this feature to configure the settings for the Muliti-Channel DRAMs
(MCDRAMs) that reside in the KL series processor. The MCDRAM is a high-
bandwidth, high-frequency DRAM and can be configured for multi-functional use.
Each KL processor contains up to eight MCDRAMs in the processor package,
and each MCDRAM works in conjunction with an OPIO (On-Package IO), which
acts as a controller for the MCDRAM.

Uncore Status
Cluster Mode
This feature allows the user to decide how to arrange all MCDRAMs that reside
in the processor into clusters. The options are
All2All , SNC-2, SNC-4, Hemi-
sphere, Quadrant, and Auto.
Memory Mode
Use this feature to set the memory mode for the MCDRAMs (MCDRAMs) in the
processor. Select Flat to configure MCDRAMs for regular use. Select Cache
to configure MCDRAMs as (L3) cache. Select Hybrid to configure MCDRAMs
for regular use and for cache use. Select Auto to allow the BIOS automatically
configure the MCDRAMs for the function specified by the BIOS. The options are
Flat , Cache, Hybrid, and Auto.
Treat MCDRAM as Hot-Pluggable Memory (Available when the Memory
Mode above is set to Flat or Hybrid)
If this feature is set to Yes, the MCDRAM will be treated as a Hot-Pluggable de-
vice which can be changed or re-configured without powering down the system.
The options are No and Yes.
OPIO Parallel Training
Select Enable to allow multiple OPIOs (On-Package IO) that work in conjunc-
tion with different MCDRAMs in the processor to be trained simultaneously to
enhance system performance. The options are
Enable and Disable.
OPIO Parallel Channel Count (Available when the item- OPIO Parallel
Training is set to Enable)
Use this feature to determine the number of OPIOs to be trained simultaneously.
The options are 2, 4, 6, and
8
.
MCDRAM Repair
Select Enable to allow the BIOS or the OS to attempt to repair the MCDRAM
when an error occurs. If the repair fails, the faulty MCDRM(s) will be taken out
