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.

No Interruptions Day Shortbread. While in the same internal event mentioned above, AMD gave a preview on the features of the SB8xx family of southbridges, as follows: 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.
This argument might sound familiar because I’ve been grinding this axe for a while now. On the overclocking front, we’ve long passed the point of diminishing returns.
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. Views Read Edit View history. Email the author s: This method drapes a string of linear slopes across multiple step points. In step mode, fan speeds jump from one value to the next as temperatures rise. All this functionality is offered for free in every SBseries south bridge, with no additional hardware required.
Merry Christmas from The Tech Report staff! CuttinHobo I heard he xmd to be called a Seth Lord Non-linear mode is just as flexible, allowing users to configure as many slopes as they can steps. They’ve come a long way in that time, adding integrated flashing utilities, support for multiple configuration profiles, and, of course, the ability to tweak a staggering array of memory timings, clock speeds, and voltages.
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. LG HU85L projector sb80 but two inches to cast a 90″ picture. Most OSes require patches in order to work reliably.
Big news, no news, and future news.
AMD’s SB to have SATA 3 support –
The Tech Report System Guide: Each one can have its own profile, and 3- and 4-pin fans are supported across the board. A view of the SB series’ fan control inputs and outputs. The codenamed “Catalunya” platform consists of codenamed “Suzuka” quad-core processors, featuring Socket AM3 db800 support dual-channel registered DDR3 memory, the platform supports HyperTransport 3. Because the south bridge can monitor and power no fewer than five individual fans. I couldn’t not graph them.
Customize The Tech Report Combine the two, and you have a non-linear approach that’s really more multi-linear.
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. 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 amc motherboard.
AMD chipset series. The linear algorithm smooths things out, allowing fan speeds to ramp, well, linearly between predefined minimum and maximum values. Steam names the best-selling games of In those cases, the thermal diode built into AMD’s north-bridge silicon can be used as a secondary temperature input. 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’s SB800 to have SATA 3 support
Motherboard manufacturers typically rely on SuperIO chips or other auxiliary silicon to adjust fan speeds based on system temperatures. 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. Retrieved from ” https: 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 wmd of south-bridge chips.
Neutronbeam Besides money, let us know Seth what WE can do to help out–there’s a lot of sma 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. 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.
PC enthusiasts have always had a bit of an obsession with maximizing performance, so it’s no surprise motherboard eb800 have lavished us with a wealth of overclocking and performance tweaking options.
AMD’s SB800 Is a Completely New Southbridge
Few seem to have picked up on the fact that we also want our rigs to be as quiet as possible, though. AMD sockets and chipsets. 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.
The IGP features wmd listed below:. 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.
