The Sabertooth supports 2 native SATA 6Gbps ports (brown) with RAID 0,1,5,10 while 4 SATA 3Gb/s ports (black) with RAID 0,1,5,10. Two Asmedia 1061 controllers provide another two SATA 6Gbps ports colored in white/grey. The eSATA 6Gbps ports located at the back panel uses one of these Asmedia 1061 controller.
Expansion slots then, the Sabertooth comes with 2 PCIe 3.0 x16 slot (single at x16, dual at x8/x8),then there's one PCIe 2.0 x16 and 3 PCIe 2.0 x1. The three graphics card slots supports NVIDIA Quad SLI and AMD Quad CrossfireX. Though with two X16 ports that's a bit of a daunting task. Then again, two dual-GPU cards would run QuadSLI. The board also supports LucidLogix Virtu MVP Technology.
So in a nutshell that is the Sabertooth Z77 preview. There's more to be found with this motherboard, ASUS now uses TUF components, which just like MSI offers, are military-standard components being used for the capacitors, MOSFETs and chokes.
New as well is DIGI+ power control, the USB Flashback feature (put the BIOS on an USB stick, power down, press the button on the back panel and it's flashing the firmware). Also a new feature is Network traffic shaping which ASUS calls Network iControl, allowing you to assign and control Ethernet bandwidth. So if you want to reserve precious bandwidth for gaming while downloading, that is now an option as you may program profiles.
We certainly like the board, it's sexy and you know it. Now all we need is an Ivy bridge processor of course. We hope you enjoyed this little preview. Once the processors are seeded we'll revisit this board with a full review, of course.
ASUS Sabertooth Z87 motherboard review We review, test and benchmark the ASUS Sabertooth Z87 TUF series motherboard. The Z87 enthusiast themed mainboard is intended for Intel's 22nm Haswell processors on Socket LGA1150.
ASUS Sabertooth Z77 review We review the ASUS Sabertooth Z77. Z77 is of course the Intel chipset predominantly released for Ivy Bridge based processors. This article is a full review of what you may expect from the TUF series Sabertooth Z77, have peek after which we'll dive right into the photo shoot.
ASUS Sabertooth Z77 preview We preview the ASUS Sabertooth Z77 TUF. Z77 is of course the Intel chipset for the upcoming Ivy bridge based processors. These motherboards will have a slightly altered feature set and thus support them new upcoming apples from Intel. Good to know however is that Z77 also supports Sandy Bridge Socket 1155 based processors, that's right your favorite Core i5 2500K and Core i7 2600K will be perfect for these motherboards as well. The changes for Z77 primarily can be found in native USB 3.0 support as well as an upgrade towards PCie gen 3 PCIe x16 slots.
ASUS Sabertooth 990FX review The TUF series (The Ultimate Force) Sabertooth 990FX is what we'll be placing under our microscope today, styled in the very same color as the earlier models with the ceramic design we see a lot of resemblances. But hey no tactical jacket anymore though. This AM3+ motherboard will be powered by a 10-phase Digi+ VRM. Socket AM3+ will support the Bulldozer based Zambezi FX Series Processors which launch later. The Sabertooth 990FX will come with four DDR3 DIMM slots supporting dual-channel memory up-to DDR3-1866 MHz straight from the EFI BIOS. What you'll also notice is that the TUF (The Ultimate Series) has four PCI-Express 2.0 x16 PCIe graphics card slots based on what you use the slots for of course. Interesting fact is that this motherboard series now is SLI compatible.
