ASUS M3A-H/HDMI

This is one of rare 780G motherboards that isn’t in micro ATX format; certainly, it isn’t full-blooded ATX because motherboard is just a bit narrower. PCB is ocher colored with proper disposition of components (this is pretty much standard for ASUS in middle range class). ASUS M3A-H/HDMI has 5-Phase analog voltage unit that should supply overclocked Phenoms very correctly. These five phases ASUS arranged in 4+1 manner, four phases is attended for processor itself and one phase is for memory controller that is integrated in processor.

Processor is supplied with power through 4-pin P4 12V connector, located on atypical place. Further along the motherboard are placed two PCIe x1 slots and between them is positioned PCIe x16 slot attended for graphics card while below are three standard PCI slot. Along right edge are placed 24-pin ATX connector and rotated IDE connector, which are pretty much standard positions. Motherboard has bulky coolers on northbridge and southbridge, so it’s no wonder why it wasn’t warming up during tests. Under southbridge are arranged six SATA 2 connectors, so none of graphics cards shouldn’t interrupt them. On bottom edge are placed pins for connecting I/O panel, four ports on which you can connect eight USB 2.0 ports and one FDD connector. Realtek audio solution in form of ALC1200 chip is reserved only for ASUS motherboards so therefore it is integrated in ASUS M3A-H/HDMI. From hardware point of view, everything is properly configured, so what only left for us to do is to check possibilities of voltage calibrations in BIOS. Voltage for CPU and memory controller (CPU-NB) is possible to adjust from 1.1V to 1.4V with 0.1V increments, while for memory is possible to set voltage from 1.9-2.25V with 0.05V increments.
