1.9 System Memory
AIMB-288E has two sockets for a 262-pin DDR5 SODIMM. These sockets use a 1.2
V unbuffered double data rate synchronous DRAM (DDR SDRAM). DRAM is avail -
able in capacities of 4 GB, 8 GB, 16 GB, and 32 GB. The sockets can take any com -
bination with SODIMMs of any size, giving a total memory size between 4 GB, 8 GB,
16 GB, and up to a max of 64 GB. AIMB-288E does NOT support error checking and
correction (ECC).
1.10 Memory Installation Procedures
To install SODIMMs, first make sure the two handles of the SODIMM socket are in
the “open” position, i.e., the handles lean outward. Slowly slide the SODIMM module
along the plastic guides on both ends of the socket. Then firmly but gently (avoid
pushing down too hard) press the SODIMM module well down into the socket, until
you hear a click when the two handles have automatically locked the memory module
into the correct position of the SODIMM socket. To remove the memory module, just
push both handles outward, and the memory module will be ejected by the mecha -
nism.
1.11 Cache Memory
The AIMB-288E supports a CPU with one of the following built-in full-speed last level
caches:
30 MB for Intel® Core™ i9-12900E/i9-12900TE 25 MB for Intel® Core™ i7-12700E/
i7-12700TE 18 MB for Intel® Core™ i5-12500E/i7-12500TE 12 MB for Intel® Core™
i3-12100E/i7-12100TE 2.5 MB Pentium® G7400E/G7400TE
The built-in second-level cache in the processor yields much higher performance
than conventional external cache memory.
