Mr. Handley then went on to describe the implementation of “Dual Power Switching” on the GIGABYTE GA-X58A-UD9. This GIGABYTE mainboard is supposed to achieve double the usual VRM lifespan by alternating between its two 12 switching phases, thereby using half of the VRM MOSFET switches at any one time. We’re not sure how the folks at Intersil sold the idea to GIGABYTE, but Mr. Handley’s speech was all about engines and gears, quite unlike the traditional water tank, wheel, and pipe analogy we are used to hearing at physics lectures.
It was also mentioned that, should one half of the VRM go down, another half is present for redundancy. Still, we have noticed that the most common VRM failure modes involve blown MOSFETs that (by the nature of MOSFET construction) instantly short the +12V rail to ground; rendering PSU startup improbable. Having redundant VRM phases sound like a great idea, but nothing quite as spectacular (and realistic) as delivering 1500W to the CPU socket, really.
The next feature announcement Mr. Handley had was “HotKey OC.” This is available on all GIGABYTE mainboards that already support EasyTune6. Invited to demonstrate HotKey OC was Taiwanese overclocker Hicookie.
With the relevant clock and voltage settings keyed into the EasyTune menu, Hicookie brought the Intel® Core™ i5-655K CPU to 4.6GHz on the GIGABYTE GA-P55A-UD4P mainboard. This was done in real-time, while the Unigine Heaven Benchmark was running. While real-time overclocking is not new, it is good to see GIGABYTE updating the EasyTune software suite for both potential customers and existing users.
Benchmarking enthusiasts can use Hotkey OC to vary clockspeeds on-the-fly, using the highest possible clockspeeds at each stage of the test to attain maximal scores. Those familiar with the Futuremark 3DMark series of benchmarks will often find that the benchmarks’ demands on stability shifts back and forth depending on the test being performed at any point in time.
What is really unheard of, is GIGABYTE Cloud OC. Performing the demonstration is Mr. Rockson Chiang, Technical Marketing Manager of GIGABYTE who produced an Apple iPad to demonstrate “Cloud OC” capabilities on the GIGABYTE platform.
What Cloud OC does is enable overclocking over the Internet, using common mobile devices to control and monitor the status of your GIGABYTE PC.
Here you see Mr. Chiang having a little quiet time to himself, fondling the iPad intensely and overclocking the GIGABYTE demonstration platform at the same time.
Seeing Mr. Chiang with the Apple iPad, Mr. Handley took the opportunity to mention the how GIGABYTE mainboards with “3x USB Power” quickly charges USB devices like the iPad.
Next up, was the Questions & Answers session. A quick witted journalist took the opportunity to question Intel representatives on the company’s support for USB 3.0 in its next generation chipsets, drawing cheers from the crowd who have seen next-to-nothing on USB 3.0 from Intel roadmaps.
When the chatter subsided, Dr. Ball confirmed Intel’s continued support for USB 3.0. It is a matter of time before Intel chipsets come with built in USB 3.0 host controllers. In other words, implementing USB 3.0 on Intel platforms will still require a separate host controller in the foreseeable future.
