Gigabyte MA78GM-S2H Layout and Features
The modest MicroATX form factor hides a real power of the motherboard. Gigabyte MA78GM-S2H looks like a commonplace value product, but in fact is offers a superb pack of features.
On the south and north bridges, there are low-profile radiators whose efficiency is quite enough in view of the low heat emission of 780G and SB700.
The power connectors are positioned conveniently. In particular, the main 24-pin connector is positioned over the bottom edge of the board and allows plugging in "old" PSUs with a 20-wire cable. The additional 4-pin connector is positioned near the rear panel of the board and will not be of any issue to the assembly operator.
Near the power supply module, there is a 4-pin CPU_FAN connector to plug in the processor cooler.
Besides it, there is one more 4-pin SYS_FAN connector (on the left-hand edge of the board).
Under the CPU socket, there are four DIMM slots, and the maximum memory capacity makes up 16 GB (4 GB for XP).
To enable the dual-channel mode, the memory modules should be inserted into the slots of the same color. It should be noted that 780G offers support for DDR2, and its maximum frequency is in direct dependence on the AMD CPU model, in which the memory controller is integrated. So, once we installed a single-core Athlon 64 3500+, the maximum memory frequency equaled DDR2-800. With a higher-end CPU, the board is able to support DDR2-1066.
As regards the expansion options, the board uses one PCI Express x16 slot (both a holder) as well as one PCI Express x1 and two PCI slots.
Note that 16 PCI Express version 2.0 lanes are allocated to the PCI-E x16 slot.
