When X58 was first announced there were rumours about its graphics card support. Would it get SLI approval from NVIDIA and would it still support Crossfire? - Originally NVIDIA specified that X58 would need to use an nForce 200 PCIe bridge chip to run SLI, but a lot of pressure was put on NVIDIA from all of the motherboard companies and SLI support was granted to X58 through a native setup allowing two or three cards. However, Intel's 3-way SLI still requires a 16/8/8 setup; not the fastest out there, but still good enough. NVIDIA still recommended its nForce 200 chipset for best performance SLI.Essentially what the nForce 200 chip does is allow the board to turn one PCI Express x16 lane into two x16 lanes by prioritising data packets along the PCIe bus and sending them down one x16 lane; this in turn gives the graphics cards direct communication to each other on the nForce 200 chip. To this end ASUS has finally produced its first X58 board paired with the nForce 200 chip. This has given ASUS the ability to provide the board three PCI Express x16 slots as well as three extra x16 slots in a variety of modes, which we will explain later.This board is available now from Newegg at a price tag of 369.99 USD
which puts it up there at the high-end along with the OC Palm and other boards. However, how many boards are able to support six graphics cards?
The Box and What's InsidePackage and Contents
First up, as always, the package. ASUS has gone with the traditional blue box design that denotes its mainstream Intel boards. Since Intel's colour of choice is blue, ASUS has followed suit. The box is of standard size for ATX boards; no oversized box here, which means we won't get as much inside the package as we did with the OC Palm or Rampage II Extreme boards. However, knowing ASUS we will get enough to keep us going.
On the back of the box ASUS has put a full colour photo with box-outs explaining the features of the board along with a full spec list on the side, which is an identical replica to the spec sheet found on the P6T6 WS Revolution page on the ASUS website. Kudos on the extra info here ASUS.
ASUS hasn't gone overboard with the reference material; there is a single user manual, however, it's almost as thick as a Steven King novel with all the info on board setup, specs, features, BIOS setup and software explanations for the included software on the DVD, which also details use of the EPU-6 power saving system that the board has built in to reduce overall system power usage when idle, as well as when under light to moderate loads.
When we said we didn't expect a whole lot in the way of accessories, we didn't quite expect to see this much in the box. First off, there are six SATA data cables along with a Molex to SATA power converter as well as a single IDE cable supporting two drives and two SAS to SATA converters with built in Molex power plugs. The board doesn't come with any onboard power or reset switches as standard; however, for the enthusiast who will get this board for overclocking and the six PCIe x16 slots, ASUS incorporated a daughter card that plugs into a header on the bottom of the board which gives it a power on/off switch, reset button and a POST code reader.
The MotherboardThe Board
It's now time to get onto the board itself. ASUS uses the same sized ATX PCB that the OC Palm was built on; the boards layout is somewhat different, however, a very good design.
The 24-pin ATX power connector is located behind the six DDR3 memory slots that make up the triple channel arrangement. These slots are coloured blue and black, three of each. The 4/8 pin AUX power connector is located above the heatpipe assembly, behind the PS2/USB combo port.
On the lower right hand side of the board we have a total of eight SATA ports; six are blue and two are black. The blue ports are actually SATA ports controlled by the ICH10R Southbridge supporting the usual RAID functions as well as AHCI. The two black ports are actually SAS compliant running off the Marvel PCIe 2-port SAS controller and these ports can take SAS or SATA drives since SAS is backwards compliant with the SATA protocol. Located under the heatsink in the picture with the "Workstation" marking on the top hides the ICH10R, nForce 200 chip and the Marvell PCIe SAS controller.
The P6T6 WS Revolution is powered by the same 16 phase voltage regulation system that the Rampage II Extreme and P6T Deluxe OC Palm uses. Like these two boards, EPU-6 is also included on this board to reduce the amount of active phases that the board uses during certain activity states. The Mosfets are cooled by a heatpipe assembly that also cools the X58 IOH, ICH10R Southbridge, nForce 200 PCIe repeater and Marvell SAS controller.
The rear I/O ports resemble that of any standard ASUS board. ASUS has gone the way of trying to remove legacy ports and only a single PS/2 port is included which can be used for either a keyboard or mouse, but not both. The same Jmicron based PCIe x1 chip that gives the board its IDE also controllers the two eSATA ports on the rear I/O shield, giving it a 300MB/s external storage system for fast access to data. The audio system is handled by the Azalia HD audio codec.
Now we come down to the complex setup of the board, namely the expansion systems. This is where we start to see some interesting setups. There are a total of six PCIe x16 slots; three blue, two black and one white.If you want to run Tri-SLI at full speed (x16) you can populate the blue slots with graphics cards capable of 3-way SLI. The first and second blue slots are run through the nForce 200 chipset which is tied to one of the two PCIe x16 lanes that the IOH supports. The last blue slot runs direct to the X58 hub. The next scenario is if you want to run four graphics cards or more; the black slots steal lanes from the other second x16 slot and convert them into x8 slots. This leaves you with a 16x8x8x8 setup with the blue and black slots. The white x16 slot is tied to the ICH10R's last four PCIe lanes.
BIOS and OverclockingBIOS
The BIOS now and this is where ASUS always puts a lot of work into their boards. Unlike the ROG series of boards, the P6T6 WS Revolution board uses the standard AI Tweaker menu for its overclocking The board's BIOS is run through the Award 6 tab BIOS as we like to call it; familiar if you use Intel Desktop boards or any of ASUS' other boards on the market.
ASUS doesn't put all of its overclocking and tweaking under the AI Tweaker menu. Under the Advanced Chipset tab you can find a few extra menus, namely the CPU Features setup.
Under the CPU configuration menu you can change the CPU multiplier depending on what CPU you have. If you are using a Core i7 series you can adjust it from its default value or the value that the Speedstep enables to help bus overclocking. If you have the Extreme series you can lower or raise the multiplier at will as well as disable the overpower protection.
The AI Tweaker menu holds all of the bus adjustments, divider and ratios as well as voltages to help tweak the board. While not as extensive as the ROG boards, it does have a fairly good range of settings.Overclocking
The ASUS P6T6 WS Revolution board is extremely tweakable for a Workstation board. While we didn't have as much time as we would like, we did managed to hit 175MHz to allow us to get a 3.8GHz clock speed; not bad at all. Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.

Power Usage and Heat TestsPower Consumption
We are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into an AC wall socket).There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.The other thing to remember is that our test system is bare minimum - only a 7,200RPM SATA-II single hard drive is used without CD-ROM or many cooling fans.So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.
With all three boards supporting the same power saving technologies and voltage circuits we see that the three boards tie it up.Heat Generation
As a new measure, we are now monitoring the heat generation from the key components on the motherboards, this being the Northbridge, Southbridge (if it contains one) as well as the Mosfets around the CPU. The results are recorded at idle and load during the power consumption tests.
The P6T6 uses a slightly different heatpipe to the other two boards so it's slightly hotter running, but only by a few degrees.
Final ThoughtsFinal Thoughts
ASUS' line of boards just keeps getting better and better. Who would have thought that overclocking would make its way into the Workstation environment? - While you won't see too many desktops in offices running extreme CPU speeds just for the fun of it, ASUS has dual purposes for this board, especially for those wanting max performance out of their graphics with 3-way SLI.The ASUS P6T6 WS Revolution board has just about everything you're going to need, including high speed Server class storage through SAS as well as support for up to six PCIe x16 graphics cards. At 369.99 USD from Newegg
, this board has some good value attached.
