ASUS Crosshair V Formula Review

Each time AMD or Intel releases a enthusiast chipset, you can be sure that ASUS will be ready with a Republic of Gamers motherboard. This time round, it's the 990FX and the motherboard waiting for us is none other than the Crosshair V Formula.

Before we dive into the Crosshair V Formula proper, let's take a look at what's changed since 890FX.

Northbridge Comparison

  990FX 890FX
Processor AM3+,AM3 AM3
PCIe 2.0 42
HyperTransport 3.1 (3.2GHz) 3.0 (2.6GHz)

And the answer is, well, nothing much at all. 990FX will use a faster HyperTransport 3.1 link when paired with Bulldozer, although with older processors it will revert to HyperTransport 3.0 speeds. Otherwise the number of PCIe lanes remains the same, and the chip is still manufactured on TSMC's 65nm process.

The good news is that AM3 motherboards only need a BIOS update to support AM3+ processors, subject of course to the board's ability to handle Bulldozer's maximum TDP (125W) and the manufacturer's willingness to provide said update. ASUS, Gigabyte and MSI have already announced the models which will be receiving an update to work with AM3+ processors, while ECS' website says that they are currently working on it. AMD does not officially support or endorse this, however.

Southbridge Comparison

  SB950 SB850
PCIe 2.0 2
SATA 3Gbps
SATA 6Gbps 6
USB 1.1 1
USB 2.0 14
USB 3.0

The SB950 is essentially a renamed SB850. SB850 was ahead of its time with SATA 6Gbps support, unfortunately SB950 doesn't continue that trend and there's no USB 3.0 support. SB950 continues to integrate PCI and PATA support, which saves motherboard makers the cost of PCIe-to-PCI bridge chips.

We couldn't find a 990FX chipset diagram, but since so little has changed here's a 890FX diagram:

Now that we're done with that, let's have a look at the Crosshair V Formula's specifications. At first glance it looks very similar to its predecessor, the Crosshair IV Formula, with a nearly-identical expansion slot layout. Notable changes include a doubling of maximum memory to 32GB, an increase in the number of USB 3.0 ports, and the eviction of FireWire.

Asus appears intent on using in-house solutions as much as possible – JMicron and Renesas have been dumped in favour of Asmedia's SATA 6Gbps and USB 3.0 controllers respectively. In our Z68 motherboard review we found the ASM1042 to be as good as other USB 3.0 controllers, but we've yet to see how the ASM1061 performs compared to the more popular Marvell 88SE9128. We're also happy to see an Intel 82583V controller on the networking front, as these usually have the lowest CPU utilization.

You might also remember the Crosshair IV Extreme, the big brother (literally) to the Crosshair IV Formula and a true hardcore overclocker's motherboard. So far there's been no word of a Crosshair V Extreme, but then there's probably no real need for one given the similarities we've already described. Turn the page for a closer inspection of the motherboard.
