3-2 Cache Memory

Since the second level cache has been embedded into the MMC1 or MMC2
modules. You do not have to take care of either SRAM chips or SRAM modules.
The cache size in the Pentium II mobile module, MMC1 or MMC2, is either
256KB (on die) or 512KB. However, for the Pentium MMC1 modules, the default
L2 cache is 512KB.
3-3 Mount-Change the CPU
The MAXI 6560 has two CPU connectors, the MMC1 and MMC2. Both
connectors connect to the MMC1 and MMC2 CPU modules respectively. Their
installation procedures are similar as follows.
The CPU modules should be fixed with three copper stand offs on the three
mounting holes at the corners of the CPU modules. These stand offs should be
on the bottom side of the CPU module.
To mount the CPU module, first move the IMM within the area of the four
mounting holes on the MAXI 6560 main board. Then carefully put the male
portion of the MMC1 on the CPU module right on the female portion of the
MMC1 on the main board. Press the CPU module evenly but firmly to the main
board until the module is completely fitted into the MMC1 (See Figure 3-3).
There are three mounting holes on the IMM modules. Just fix them with the
stand offs and screws.
We also offer the optional heat sink with cooling FAN. If the heat sink kit is
requested, it should be fixed to the CPU module first, then you could install the
CPU module on to the MAXI 6560.
Please be noted that for the MMC2 CPU modules, a big proprietary heat sink is
offered as an option for those applications like high CPU performance. No fan
allowed and ruggedized construction. The heat sink is only available for MMC2
modules, not for MMC1 modules.
