AMD Southbridge SB chips to include built-in Serial ATA 3 support. AMD’s SBseries fan speed controller exposed. Options aplenty make this motherboard reviewer swoon by Geoff Gasior — AM on. I’ve been a big fan, pun intended, of fan control options in the BIOS. Some motherboards have real basic functionality while some of have been excellent.

AMD’s SBseries fan speed controller exposed – The Tech Report – Page 1

AMD sockets and chipsets. Customize The Tech Report Each one can have its own profile, and 3- and 4-pin fans are supported across the board. Current information about the chipset series is very scarce, while the officially published information about the series is the server chipsets with two variants available, the AMD S chipset and the AMD S chipset, all of them paired with the SBS series southbridge. Merry Christmas from The Tech Report staff! I went off on a bit of a rant on the subject more than a year and a half ago, and little has changed since.

Because the south bridge can monitor and power no fewer than five individual fans. Neutronbeam Besides money, let us know Seth what WE can do to help out–there’s a lot of sma MSI’s fan speed controls remain limited but continue to offer at least some tuning options, while Gigabyte’s are still shockingly nonexistent. Instead of being limited to single high and low values, AMD’s step mode can accommodate no fewer than eight predefined fan speeds and corresponding temperatures.

This argument might sound familiar because I’ve been grinding this axe for a while now. PC enthusiasts have always had a bit of an obsession with maximizing performance, so it’s no surprise motherboard makers have lavished us with a wealth of overclocking and performance tweaking options.

So, imagine my delight when, at AMD’s Technical Forum in Taipei last week, I came across a presentation sb8000 the fan speed controls enabled by the company’s current generation of south-bridge chips. Motherboard manufacturers typically rely on SuperIO chips or other auxiliary silicon to adjust fan speeds based on system temperatures.

On the overclocking front, we’ve long passed the point of diminishing returns. Retrieved from ” https: Motherboard makers need only to connect fan and diode traces to the south bridge and implement the necessary BIOS hooks to give users access to fan control variables. In step mode, fan speeds jump from one value to the next as temperatures rise. CuttinHobo I heard he prefers to be called a Seth Lord About us Privacy policy Mailing list Mobile.

The codenamed “Catalunya” platform consists of codenamed “Suzuka” quad-core processors, featuring Socket AM3 and support dual-channel registered DDR3 memory, the platform supports HyperTransport 3. These two processors support a new socket called Socket G34 with four-channel DDR3 support, with other platform features such as HyperTransport 3.

No Interruptions Day Shortbread.

Any halfway-decent motherboard BIOS has more than enough clock and voltage ranges for enthusiasts, and most go above and beyond what even truly extreme liquid-nitrogen-fueled overclockers might require. The IGP features are listed below:. Advanced Micro Devices chipsets.

Putting this functionality in the chipset certainly makes sense, but has AMD implemented the sort of functionality enthusiasts might want? AMD’s Ali Akbar Merrikh, the man who designed the fan speed controls and patiently answered my questions about them, isn’t aware of any motherboard that exploits the SB’s fancy fan controller outside the company’s own boards and reference designs, none of which are available to consumers.

AMD’s SB800 Is a Completely New Southbridge

AMD does not provide any SB8x0 errata publicly. The chipset series is targeted in three markets: Linear mode is most akin to what’s available in contemporary BIOSes, although users aren’t always able to set minimum and maximum temperature thresholds and fan speeds.

LG HU85L projector needs but two inches to cast a 90″ picture. The linear algorithm smooths things out, allowing fan speeds to ramp, well, linearly between predefined minimum and maximum values. Big news, no news, and future news.

That’s a travesty, because this is exactly the sort of fan speed control that I’m sure many an enthusiast would love to have in his motherboard’s BIOS. The fan speed controls available in most modern BIOSes are basic at best and often laughably inadequate when compared to the frankly excessive overclocking options being offered. All this functionality is offered for free in every SBseries south bridge, with no additional hardware required.

Most OSes require patches in order to work reliably. Steam names the best-selling games of In addition to the three algorithms that determine how fan speeds respond to temperature changes, the SB series is governed by single- and dual-sensor policies that dictate how temperatures are interpreted.

AMD’s SB to have SATA 3 support –

The microcontroller can manage fan speeds using three algorithms: I couldn’t not graph them. Non-linear mode is just as flexible, allowing users to configure as many slopes as they can steps. Sbb800 Wikipedia, the free encyclopedia. Single-sensor mode relies on only one temperature sensor, while the dual-sensor scheme takes in two inputs and will set the fan speed based on the higher of the two.

They’ve come a long way in that time, adding integrated flashing utilities, support for aamd configuration profiles, and, of course, the ability to tweak a staggering array of memory timings, clock speeds, and voltages.
