NTRODUCTION
It is important to be aware of the system considerations listed below before installing your JXT6966 or
JXTS6966 (S6966-xxx) SHB. Overall system performance may be affected by incorrect usage of these
features.

If you have an IOB33 I/O board in your system and you are using a “Y” cable attached to the bracket
mounted mouse/keyboard mini Din connector, be sure to use Chassis Plans’ “Y” cable, part number 5886-
000. Using a non-Chassis Plans cable may result in improper SHB operation.

EMORY
Chassis Plans recommends ECC registered DDR3 memory modules for use on the JXT6966/JXTS6966
SHBs and these ECC registered (72-bit) DDR3 Mini-DIMMs must be PC3-10600 or PC3-8500 compliant.
Unbuffered ECC DDR3 Mini-DIMMs are also supported on the JXT boards, but you cannot mix the two
different memory types on the same SHB.
NOTES:
To maximize system performance and reliability, Chassis Plans recommends populating
each memory channel with DDR3 Mini-DIMMs with the same interface speed.
All memory modules must have gold contacts.
Low voltage (DDR3L) Mini-DIMMs are not supported.
The SHB supports the following memory module memory latency timings:
o
6-6-6 for 800MHz DDR3 Mini-DIMMs
o
7-7-7 and 8-8-8 for 1066MHz DDR3 Mini-DIMMs
o
9-9-9 for 1333MHz DDR3 Mini-DIMMs
Populating the memory sockets with Mini-DIMMs having different speeds is supported
on the SHB; however, the overall memory interface speed will run at the speed of the
slowest Mini-DIMM.
Populate the memory sockets starting with the Mini-DIMM socket closest to the CPU
and work your way toward the edges of the SHB as illustrated in the chart below:
Population order
CPU1
CPU2*
1
BK00
BK10
2
BK01
BK11
3
BK02
BK12
*CPU2 is available on the JXT6966 dual-processor board version only
*Using a balanced memory population approach ensures maximum memory interface
performance. A “balance approach” means using an equal number of Mini-DMMs
for each processor on a dual-processor JXT6966 SHB whenever possible.
The memory DIMMs on the SHB connect directly to the CPU and at least one memory module must be
installed on the board. The JXTS6966 SHB versions feature one processor; however, memory sockets
BK10, BK11 and BK12 are installed on the SHB but are not active in this single-processor board version.
SATA
RAID

PERATION
The Intel
®
3420 Platform Controller Hub (PCH) used on the SHB features Intel
®
Rapid Storage
Technology (Intel
®
RST), which allows the PCH’s SATA controller to be configured as a RAID controller
supporting RAID 0, 1, 5 and 10 implementations. To configure the SATA ports as RAID drives or to use
advanced features of the PCH, you must install the Intel
®
RST driver software. A link to the software is
also located on Chassis Plans’ website by accessing the Downloads tab of the JXT6966 product detail page
or the RAID Drivers section of the Technical Support page.
