Gigabyte AM1M-S2H Software and Firmware
The AM1M-S2H includes Gigabyte’s EasyTune6 software, though tuning isn’t so easy on a multiplier-locked processor. DRAM ratios are selectable, but only go to DDR3-1600. And a few voltage levels can be increased, but without the higher data rates that would necessitate an increase.
There is a knob you can use to tweak the APU's GPU clock, and that setting is found in the board's firmware. But don't expect much from it; the Radeon graphics engine is fed by a single 64-bit channel of DDR3-1600 memory, at best.
As with the Asus board we just looked at, Gigabyte’s offering supports Intel’s XMP technology for DRAM. You’re still stuck with a DDR3-1600 limit, but some modules can push CAS 7 at this data rate with a little voltage applied.
DRAM timings can also be configured manually, if you really want to take the time to extract maximum performance from your low-energy CPU.
Even though you can’t overclock the CPU, Gigabyte still lets you dial in some “Loadline Calibration” to stabilize voltage. Consider this feature unnecessary until AMD can be convinced that we need a more flexible Kabini-based APU.
