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.

Big news, no news, and future news. Email the author s: This page was last edited on 25 Septemberat Combine the two, and you have a non-linear approach that’s really more multi-linear.
AMD’s SB Is a Completely New Southbridge
These two processors support a new socket called Socket G34 with four-channel DDR3 support, with other platform features such as HyperTransport 3. All this functionality is offered for free in every SBseries south bridge, with no additional hardware required. Amf Read Edit View history. From Wikipedia, the free encyclopedia.
Neutronbeam Besides money, let us know Seth what WE can do to help out–there’s a lot of sma Ame this functionality in the chipset certainly makes sense, but has AMD implemented the sort of functionality enthusiasts might want? 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.
Because the south bridge can monitor and power no fewer than five individual fans. AMD’s Sb8000 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.
Most OSes require patches in order to work reliably.
Few seem to have picked up on the fact that we also want our rigs to be as quiet as possible, though. 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.

Webarchive template wayback links Articles with Japanese-language external links. I couldn’t not graph them. The codenamed “Maranello” platform consists of six-core “Sao Paulo” or twelve-core “Magny-Cours” processors. 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. The IGP features are listed below:.
So, imagine my delight when, at AMD’s Technical Forum in Taipei last week, I came across a presentation on the fan speed controls enabled by the company’s current generation of south-bridge chips.
Props to Merrikh and AMD for incorporating such powerful fan control support in the south bridge, and shame on any motherboard maker that leaves this particular feature untapped in favor of alternative fan control mechanisms that offer less, well, control.
On the overclocking front, we’ve long passed the point of diminishing returns. 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.
LG HU85L projector needs but two inches to cast a 90″ picture. 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.
AMD 800 chipset series
While in the same internal event mentioned above, AMD gave a preview on the features of the SB8xx family of southbridges, as follows: The microcontroller can manage fan speeds using three algorithms: Dell returns to the stock market after six years. Motherboard chipsets List of AMD chipsets. Non-linear mode is just as flexible, allowing users to configure as many slopes as they can steps.
The linear algorithm smooths things out, allowing fan speeds to ramp, well, linearly between predefined minimum and maximum values. In fact, I’d wager that most of us would happily trade the ability to tweak obscure memory timings and system voltages for such robust fan control functionality.
In step mode, fan speeds jump from one value to the next as temperatures rise. Retrieved from ” https: AMD does not provide any SB8x0 errata publicly.
A view of the SB series’ fan control inputs and outputs.
AMD SB Southbridge supports Fusion
There’s plenty of granularity, too. The SB family of south-bridge silicon has an integrated microcontroller that, with a little help from firmware built into a system’s BIOS, can offer more control over that system’s fans than has ever graced a motherboard.
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.
Advanced Micro Devices chipsets. Merry Christmas from The Tech Report staff! 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. Customize The Tech Report
