MOTHERBOARD WITH DUAL MEMORY SLOTS AND COMPUTER SYSTEM WITH THE SAME

摘要

A motherboard with dual memory slot is disclosed. The motherboard includes multiple first memory slots, multiple second memory slots, a storage unit, and a CPU. The first and second memory slots are used for connecting with memory modules of different specifications. A storage unit stores BIOS which identifies the specification of the memory module in booting, and the identification result is provided to the CPU. Consequently, the memory controller in the CPU controls the reading and writing to the memory module according the determining result of the BIOS. As a result, a single motherboard supports memory modules of different specifications, and the flexibility of using the memory modules is improved.

主权项

1. A motherboard with dual memory slot, applied with a central processing unit (CPU) including a memory controller, the motherboard comprising:
a plurality of first memory slots for connecting with a plurality of first memory modules and coupling to the CPU; a plurality of second memory slots for connecting with a plurality of second memory modules and coupling to the CPU; and a storage unit storing BIOS and coupling to the CPU, wherein the BIOS reads Serial Presence detect (SPD) stored in a memory module at the first memory slot or the second memory slot and generates a determining result representing whether the memory module complies to a first specification or a second specification, wherein the first memory module complies to the first specification, and the second memory module complies to the second specification; wherein the memory controller of the CPU controls reading and writing to the first memory module or the second memory module according the determining result of the BIOS.
