A very important part of overall system responsiveness is down to hard drive performance. We use one of our favourite benchmark utilities – CrystalDiskMark X64 Edition – to rate performance from the on-board SATA controller.
The SATA 6GB/s ports operating from the 990FX Extreme9's SB950 Southbridge are able to push the performance of modern SSDs. While our results may be short of the Kingston HyperX 3K SSD's potential speed, a resource-hogging operating system installed on the device is limiting the drive's performance.
The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.
The ATTO benchmark proves that the ASRock 990FX Extreme9 motherboard's SATA 6GB/s ports won't bottleneck a modern SSD.
Great motherboard, they deserve to be recognised more in the enthusiast sector. I love my ASROCK Z77 board
Nice look board and excellent overclocks. I want to upgrade my AMD system this year, but have been waiting on the new products.
It is a little expensive IMO for what you get, Intel boards start way under £100 today.
Great board, sexy layout and well featured. BUT as overclocker i feel 1.5v core is just too much, even for AMD CPUs…. The marginal gains that you get from 600mhz for about 0.3 vcore increase is not worth it. For 5.0ghz, is ok, 1.5 vcore would be understable, but going upper than that is just too away from my comfort zone. I dont know if I can blame the board or a bad chip. Good review !
The Extreme9 990FX will do very well with a 8370E. Does good enough with 9590 (I call the lazy overclockers board combo). Don’t expect it to overclock the 9590 much. It does run all 8 cores at 4.9 ghz all day with turbo turned off (a little better than 4.7/5.0 stock setting for most things). Recognizes the Avexir 2400 speed ram and sets it automatically. Just make sure you have room for a big twin tower air cooler.or a least a 240mm water cooler so you can keep that temps down.
It does very well with crossfired R9 285s OC to 1100 Mhz (water cooled also).
If you are going to do something likes need a big case and big power supply too. Like around 1100 watts. 285/380s need a lot more cooling to push them over 1000Mhz
