PCE-5125 User Manual 12
(JOBS1) is a 2-pin connector for setting enable/disable alarm while the on-board
security event acts.
1.9 System Memory
PCE-5125 has two 240-pin memory sockets for (ECC) DDR3 1066/1333 MHz mem-
ory modules with maximum capacity of 8GB. (Maximum 4GB for each DIMM)
PCE-5125 QG2 and QVG SKUs support non-ECC DDR3 memory modules.
PCE-5125 WG2 SKU supports ECC and non-ECC DDR3 memory modules.
Please be noted that PCE-5125 does NOT support registered DIMMs (RDIMMs).
1.10 Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM socket are in the
“open” position. i.e. the handles lean outward. Slowly slide the DIMM module along
the plastic guides on both ends of the socket. Then press the DIMM module right
down into the socket, until you hear a click. This is when the two handles have auto-
matically locked the memory module into the correct position of the DIMM socket. To
remove the memory module, just push both handles outward, and the memory mod-
ule will be ejected by the mechanism in the socket.
1.11 Cache Memory
CPUs supported by PCE-5125 have 8MB, 4MB, 3MB L2 cache memory sizes.

Note! Because PCE-5125 supports Intel Active Management Technology 6.0
(iAMT6.0) which utilizes some memory space of channel 0, it's sug-
gested that the user should not leave channel 0 DIMM slots (DIMMA1)
empty, or it may cause some system abnormality.
