Gigabyte GA-P35-DQ6 Intel P35 Motherboard Review
Gigabyte GA-P35-DQ6 Intel P35 Motherboard Review - PCSTATS
The new mainstream Intel P35 Express Northbridge looks quite a lot like Intel's old P965 series chipset, but with two very major inclusions; support for 1333 MHz Front Side Bus and official support for DDR3 RAM.

High end components, Ultra Durable 2

Recently, Gigabyte made some quiet announcements about its application of solid state capacitors paired with improved ferrite core choke coils, Low RDS MOSFET's and comprehensive passive cooling thermal solutions (aka, damn big heatsinks everywhere). The combination of all these parts, according to Gigabyte, helps reduce temperatures, improve power efficiency to the CPU and improve PC stability under load. The collection of features has been suitably marketed as "Gigabyte Ultra Durable 2" on the GA-P35DQ6 motherboard.

You may or may not recall the problem of burst capacitors that turned into an industry wide epidemic a few years ago. What caused poor quality electrolytic capacitors to burst after ~3 years is a story of industrial espionage, stolen chemical recipe's, and cut rate electronic components. Motherboard makers learned a hard lesson, and consequently the use of higher quality Japanese-made electrolytic capacitors, and conductive polymer solid-state aluminum capacitors has been stressed on virtually every flagship motherboard to be released since.

Solid state capacitors improve overall stability, and last significantly longer than the electrolytic variety. When the burst capacitor problem really hit, many computers suffered intermittent errors and crashes. Only opening up the PC case to inspect the motherboard revealed that the little aluminum capacitor cans had split, popped, and leaked gooey brown electrolyte all over the place. Motherboards from almost every vendor suffered to one degree or another, leaving users like you and me stuck with out of warranty boards that no one wanted back, that no longer worked.

While a background in electronics is necessary to really understand how the interaction of the three electrical components results in a better product, the basic gist of the technology is worth knowing. The average desktop motherboard lifecycle lasts from 6 months to 3 years, and we think it should operate reliably for at least that span of time.

If you've never looked twice at motherboard and know nothing about what all the little black and grey spots actually are, let alone do, you're in for a treat. In the above slide are the three components of Gigabyte's Ultra Durable 2 approach. This is hardly a unique collection of electrical components, so it's mainly significant because Gigabyte is making an effort to stress build quality over features. Shown here are the Ferrite Core choke coil (this helps filter out EMI/RF interference), the LOW RDS(on) MOSFET (power circuitry), and the 'All-Solid' Polymer capacitor.

Gigabyte uses high quality components with its GA-P35-DQ6 motherboard. Essentially we're starting to see manufacturers move away from the cheap stuff normally used to stick with parts that are traditionally found with high end videocards. From solid capacitors to high quality RF chokes. There are two rows of MOSFETs which help divy up the power for the various devices connected to the computer.

Compared to standard Electrolytic capacitors which use a fluid electrolyte, the 'all-solid' style polymer capacitor is beneficial because it has a longer lifespan for the same given elevated temperature that is common to the inside of a computer. As temperatures increase, the lifespan of electrolytic capacitors begins to decline. The same general rule of thumb holds true for MOSFETs as well, and according to Gigabyte's information the LOW RD(on) variety can operate with decreased heat output. A Ferrite Core RF Choke has high electronic resistance, better high frequency operation, operates at a lower temperature, has reduced magnetic leakage, and several other qualities Gigabyte engineers feel are desirable.
