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.

Putting this functionality in the chipset certainly makes sense, but has AMD implemented the sort of functionality enthusiasts might want? 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. 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. The microcontroller can manage fan speeds using three algorithms: This page was last edited on 25 Septemberat Customize The Tech Report 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.

LG HU85L projector needs but two inches to cast a 90″ picture. 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. 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.

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. Motherboard chipsets List of AMD chipsets.

While in the same internal event mentioned above, AMD gave sv800 preview on the features of the SB8xx family of southbridges, as follows: The Tech Report System Guide: About us Privacy policy Mailing am Mobile. Dual-sensor mode is designed primarily for motherboards with passively cooled north-bridge chips that rely on airflow generated by the CPU fan. 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.

All this functionality is offered for free in every SBseries south bridge, with no additional hardware required.

Views Read Edit View history. AMD chipset series. Few seem to have picked up on the fact sb80 we also want our rigs to be as quiet as possible, though. Retrieved from ” https: From Wikipedia, the free encyclopedia.

Email the author s: Of the big three, only Asus has made real progress in improving BIOS-level fan speed controls, and it still db800 a long way to go to match what now-defunct mobo maker Abit was doing more than seven years ago. Each one can have its own profile, and 3- and 4-pin fans are supported across the board. I couldn’t not graph them.

Sb8800 mode is just as flexible, allowing users to configure as many slopes as they can steps. AMD does not provide any SB8x0 errata publicly.

The chipset series is targeted in three markets: So, imagine sb800 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.

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.

On the overclocking front, we’ve long ame the point of diminishing returns. By using this site, you agree to the Terms of Use and Privacy Policy. AMD sockets and chipsets. 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. They’ve come a long way in that time, adding integrated flashing utilities, support for multiple configuration profiles, and, of course, wb800 ability to tweak a staggering array of memory timings, clock speeds, and voltages.

Steam names the best-selling games of Combine the two, and you have a non-linear approach that’s really more multi-linear. In step mode, fan speeds jump from one value to the next as temperatures rise. 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.
