Where the Deluxe 4 shines is its feature front, and doing so it takes advantage of everything the 890FX chipset has to offer.  At its forefront is its excellent USB 3.0 performance and compatibility. Unlike most boards on the market that offer two USB 3.0 ports, ASRock offers total four USB 3.0 ports, and from our experience the performance and compatibility is top-notch.  Out of the four ports, two of them are accessible at the front of enclosure via a bundled 3.5” front-panel bay unit.  We had no trouble installing it in popular tower cases like Antec Nine Hundred and Cooler Master HAF 932.  Coupled with whopping eight SATA 6.0 Gbps ports, the Deluxe 4 seems as feature-rich as any you can find in a today’s motherboard.

3.5” Front-bay USB 3.0 ports - ASRock

Another area the Deluxe 4 impressed us is its fan control ability.  The board has total 6 fan headers, and 5 of them are controllable in one way or another via BIOS or the excellent OC Tuner utility in Windows.  The OC Tuner Utility is the Deluxe 4’s command center for system monitoring and in-OS overclocking, and despite its appearance it does what it is supposed to do with no fuss.  However, we wish ASRock was a bit more attentive to the individual headers’ locations.  All six headers are somewhat crowded around the CPU socket, making it difficult to reach if you want to use them for your case’s front or side fans.     

Overall, ASRock’s entry (the short-lived Deluxe 3 notwithstanding) into this high-end AMD market is solid, but with a couple of nagging issues such as over- voltage and tight memory parameters that hinder high frequency overclocking.   We are aware that this is our first evaluation of the 890FX-based board and do not want to be unfair to the Deluxe 4 without comparing it to similar products, but at this segment of market users tend to expect perfection.

Putting that aside, the Deluxe 4 offers everything but the kitchen sink, and everything except the kitchen sink just worked without a hitch.   The board showed an exceptional compatibility with a wide range of add-in cards, and its USB 3.0 ports worked out of the box with the included drivers unlike ASUS M4A89GTD Pro/USB3 whose USB 3.0 ports seem finicky to date.  The way ASRock configured SATA ports for AHCI and hot-swap function in the BIOS is brilliant, and will bring smiles to users who have ever struggled to get hot-swap working in Windows.  We feel the Deluxe 4’s MSRP of $180 is fair enough for the majority of users who are looking to build a Phenom II X4/X6 based system with reasonable 24/7 overclocking in mind and with room to grow. (N.B.: undervolt your memory!)  Extreme overclockers and memory aficionados may well be better served by looking elsewhere.

    It is good to see a USB 3.0 performance test in there. I would like to see another or more, especially something simultaneous- for example, run backup on one port (say, USB 3.0) and stream video from a webcam in another (probably USB 2.0). This test makes a lot of sense in that a user would engage in Social Media while running a backup in the background.

    It would also tell us if the system can maintain a steady webcam image while doing other work, something we would expect a 6-core system to do (if not hobbled by poor USB implementation). The test could be repeated for a port on each USB 2.0 controller on the M/B to make sure each USB port set is as able as the rest.

    I appreciate your constructive comment. I will keep it in mind.

    Really a great review. I almost wish I would have held out building a new system until these 890's came out with USB3 and such (I built last Janurary). But I have no real complaints about my 790GX.

    Asrock has Asus as it's parent company and I thought that Asrock was supposed to be the low priced/budget branch of Asus. By taking Asrock upscale, isn't Asus just competing against itself?
  • mino - Tuesday, August 31, 2010 - link

    Not anymore. ASUS spun off it OEM arm (Pegatron) last year.

    And even when they had the same parent company, the design teams were separate since ASRock inception 7yrs ago.

    ASRock works well on the budget M/B market and try to offer more with lower price for high-end market. If you would like to get "Valued product" at mainstream segment, ASRock is a good choice.

    Very true! I've ended up buying several Asrock P55 Deluxe boards because this
    performs so well (i7 870 @ 4.1GHz), costs very little (less than 70 UKP) and it
    has excellent slot spacing (as with this review board, I really like the 3-slot
    spacing between the 1st and 2nd PCIe slots; I use the 3rd slot for a SAS RAID
    card. At least ASUS has done the same thing aswell). See:

    http://www.sgidepot.co.uk/misc/Asrock_P55_Deluxe.j...

    I'm a tad out of touch with AMD boards atm, but if I was buying an X58, I'd go
    with Asrock's Extreme6; it won't give the best overclocks, but the slot spacing
    again wins it for me. And if I was looking for an AMD board, again I like the
    890FX-Deluxe's slot spacing *and* the fact that it does have a 3rd PCIe slot
    (I notice the ASUS board doesn't). Oh for a board like this with onboard SAS...

    Don't you mean M4A89GTD PRO/USB3? http://www.newegg.com/Product/Product.aspx?Item=N8...

    Yes, thank you. Will fix it ASAP.

    Kane Jeong why didnt you mention in this article how AMD's AHCI driver doesnt support trim even w/ the newest 890FX chipset? Its supposed to be an enthusiast chipset but doesnt even provide a working AHCI driver?? For everyone that owns an SSD, we're completely left in the dark w/ any AMD chipset and SSD combo. Its august 2010, latest 890FX chipset, and on an SSD AMD doesnt even support TRIM w/ their latest drivers. This is unacceptable!!!! You guys need to address this in ANY AMD chipset review, what enthusiast wants a system that doesnt provide SSDs w/ TRIM support??? We're all stuck using MS default AHCI drivers lest we lose TRIM support, its pathetic and way overdue for AMD to provide a working AHCI driver. Please mention this in your reviews cause the vast majority of enthusiasts have SSDs, and an enthusiast chipset geared towards us without TRIM support is a joke.
