three new PC motherboards for the latest AMD platform, featuring '333' onboard acceleration.
As it was said, the new tech consists of the latest connectivity: USB 3.0, SATA III (6Gbps). The other '3' is for the fact the motherboard can supply up to three times the rated power of a standard USB port.
To quote: Gigabyte has now put online the complete specifications about these three upcoming motherboards. Despite them resembling the MA790FXT-UD5P, the MA790XT-UD4P and the MA770T-UD3P, one may notice many new features.
First of all, on the high-end model, there are now three PCI-E x16 slots instead of only two, so three videocards can now be set in CrossfireX, running in x16, x8, x8 mode. Having only two PCI-E x16 slots is a big disadvantage to the MA790FXT-UD5P when looking at boards like the MSI 790FX-GD70 having four of them, so this is great.
The next feature is 'Precision OV', which stands for OverVoltage. This means all three motherboards are equipped with a hardware voltage control chip, bringing three main advantages:
• Provides more voltage control options for CPU, NB & memory than before
• HW linear real time voltage control, no delay compared to previous GPIO controller
• Finer stepping of 20 mV min (0.002V)
We're eager to see what is meant by "more voltage control options", because the MA790FXT-UD5P already has all the required voltage adjustments for overclocking.
The 20mV increments are definitely an amelioration though. Currently, Gigabyte AMD motherboards have a stepping of 25mV, which we find a tad too coarse; we often rely on AMD Overdrive to give us that last 0.0125V.
The MA790FXTA-UD5 also features two eSATA/USB combo ports at the back. With the current models, an expansion bracket is provided to provide two eSATA ports.
