    Photo’s


    The Asrock Z490 Phantom Gaming-ITX/TB3 comes well packaged in a deep rectangular package. Opening the 18.6cm wide x 23.2cm long x 11.5cm high package, the motherboard is provided in an anti-static bag for protection.


    [​IMG]


    Extras provided from Asrock include a Quick Installation Guide, Software Setup Guide, M.2 Screws, 2x SATA cables, Post Card, driver DVD, case badge, Velcro cable ties and Wi-Fi Antenna. Sometimes I’m not sure who comes up with the idea of what to include, but a post card I feel is just a bit pointless.


    [​IMG]


    Onto the motherboard now, Asrock have gone with a Grey/Black themed gaming look. The board is very compact, utilising a riser card for extra SATA connections, RGB header and NVMe M.2 positioning. Heatsinks are linked between the CPU/IO, chipset and drive riser card via heatpipe to increase the cooling surface area. The only hint of RGB available is on the lower edge on the backside providing a light glow, unfortunately to be hidden by the installation of any GPU in the lower PCIe slot.


    [​IMG]

    The rear IO continues the accent theme on the integrated IO Shield. Ample connectors are provided including HDMI, Displayport, Wi-Fi antenna connectors, 5 audio ports plus optical audio, Thunderbolt 3 Type-C port, Realtek 2.5G LAN, 2x USB 3.2 Gen 1, PS2 KB/Mouse, 3x USB3.2 Gen 2 and finally the clear CMOS button.


    [​IMG]


    Like the other ITX motherboards available in the line-up, power is supplied through a single 8pin EPS located at the top corner of the motherboard, providing up to 235W continuous feed to the CPU. Opposite the separate actively cooled anodized grey aluminium heatsink is the first addressable RGB header plus the CPU fan header and dedicated AIO pump headers.

    [​IMG]


    The side of the motherboard we have the 24pin ATX power connector, 2x SATA connectors, front panel USB3.2 Gen 1 connector, a second RGB LED connector, system panel header and TPM module connector. Like the MSI Z490i Unify, I feel the TPM position is in a really bad position provided with the PCI-E slot clip inhibiting the access. Given the available real estate, 2x DIMM slots are provided like most ITX boards supporting what Asrock claims up to 4666+ MHz with the right combination of Memory IC and CPU IMC. It also supports up to 64GB RAM.


    [​IMG]


    [​IMG]




    Onto the bottom edge we have the Realtek ALC1220 HD audio codec. Directly beside the audio headers is the front panel connectors which can be awkward to access in smaller areas especially if the GPU is installed first. USB 2.0 front panel connector is squeezed in to the right of the front panel connectors and labelled for clarity. The reinforced PCIe 4.0 expansion slot supports operation at x16, but Asrock have also provided support for PCIe bifurcation to split into x8/x8 or x8/x4/x4.


    [​IMG]


    [​IMG]


    Asrock provide a riser board that utilises a SO-DIMM slot for the first M.2 Slot, 2 extra SATA Ports, front panel USB 2.0 connector and speaker connector as well as a chassis intrusion header. Removal is as simple as unscrewing 2 screws on the integrated aluminium heatsink and popping the clips free. On the edge, Asrock has also included a Post Status Checker LED’s for diagnosing boot issues between CPU, DRAM, VGA or Bios. I did find these screws really hard to get to for the removal, so make sure you have a nice ling shaft and magnetised end to make it easier.


    [​IMG]

    The second M.2 slot is located on the back side of the motherboard in a much easier position to access. Sneaking in the bottom of the photo, we can see the 3 LED’s providing all of the motherboard’s on-board RGB lighting. All RGB lighting able to be controlled by Asrock’s Polychrome RGB software.


    [​IMG]


    Removing the remainder of the 230g of heatsinks we are left with the bare board to be inspected. The heatsink is of an aluminium construction with active cooling via a small integrated ran above the I/O with heatpipe connecting the IO heatsink to the PCH/M.2 sinks. The top VRM sink is separated from the rest of the heatsinks, with an additional small fan for active cooling when needed. The heatsinks do an adequate job of cooling the 90A mosfets under heavy load from the 10 core processors.



    [​IMG]


    [​IMG]


    [​IMG]


    Into the business end, Asrock have included an 6+2+1 phase VRM design on the Phantom Gaming ITX/TB3. Removing the heatsinks, we are confronted by a total of 6x ISL99390 90AMP mosfets and 3x ISL99227 60AMP mosfets. From what I can tell, 6 full phases feed the 10th GEN Intel CPU rails, 3 Phases for the SOC and IO I believe. All of these phases being controlled by the ISL69269 regulator more than capable of powering the 10 core CPU’s on offer currently.


    [​IMG]


    [​IMG]


    [​IMG]


    Finally, with the I/O cover removed we can see the Intel AX201NGW Wi-Fi 6 module. No special branding to be seen here, just a solid communication module doing its thing. Unlike other boards tested though, this one does need antenna connected for a signal.


    [​IMG]




    Final Thoughts


    Alright, there we have it people. Asrock have again come to the market with a pretty solid little board here. In the 2 weeks I had it setup in my daily for testing, it proved to have very nice memory performance for 2D work and a more than capable VRM to handle the 10 core i9 10900K at a nicely overclocked frequency.


    Board layout was pretty east to get around, with most header in pretty well positioned locations. The only connections proving difficult for my semi fat fingers being the HD Audio connector squished in the corner near the bottom of the I/O heatsink and the front panel switches which were a pain if you had the RAM installed or FAN headers first.


    The VRM circuitry is ample to take on the thirsty i9 10900K. As we know, the ITX form factory isn’t super conducive to a large VRM system, but with 6x 90A CPU phases plus 2x 60A for the SOC there is plenty of headroom to handle what these CPU’s need fed. VRM heatsink temps were higher than some others I have checked, reading over 60 degrees with a temperature probe when installed in the chassis which is more than within spec for the Mosfets.


    Asrock have got a lot of their memory systems quite well tuned these days. The Phantom Gaming- ITX/TB3 wasn’t able to hit the same frequency as the other boards, but, was more than able to keep up when it came to memory latency even with up to a 200mhz speed handicap. The limit for me on my particular set of G.Skill TridentZ Royal 4000C17 sticks topped at 4400C17-17 for a nice daily setup. The main contributing factor being the Asrock BIOS engineers auto tuning the sub timings well, but also correctly setting the often forgotten about RTL and IOL settings.


    [​IMG]


    Benchmark performance was surprising with some pretty good 2D performance. 3D performance though was a bit behind. I spent a bit of time to troubleshoot why, but seems to be something amiss in the setup. You can check the results against the other boards in my round-up post (Coming Soon).


    Bios layout and feel is very Asrock. The menu’s are simple to navigate and most settings names are easily recognised.


    Asrock as their Phantom Gaming-ITX/TB3 naming suggests, provided a Thunderbolt 3 controller on their offering. It’s a welcome addition given the space constraints in an ITX form factor and given the uses, many people will be wanting that ability to connect their super-fast external USB drives, 10Gbe network or even external dock stations.


    [​IMG]



    We have a full featured Realtek ALC1220 HD audio codec, the same as all other boards in this generation. There is a lot less emphasis on the audio from Asrock on this board though, lacking some extra capacitance and physical PCB isolation, but for most people there is no loss in quality or noise.



    For the overclockers, the Phantom Gaming-ITX/TB3 isn’t going to be the strongest for pushing past where most enthusiasts will go. Basic setup was fairly simple, but with the 10900K, there was times it would power throttle even at stock due to utilising the stock TDP limit. A couple of quick setting changes alleviated the problem allowing it the headroom to overclock in line with competitors boards.


    Voltages are quite limited and I found that setting over 1.5V VDIMM would result in failed boots. Perfect for those wanting to gain that little extra in a daily gamer/stream PC outside of this, capable of holding my ES i9 10900K at 5.2G for non-AVX workloads and 5.1G for heavier AVX based rendering tasks. It’s understandable on an ITX board that there needs to be limits, but many people look to use the ITX variants for their higher memory frequency abilities and this just hampered the experience for me.


    Pros

    Memory Latency

    10 Layer PCB

    2D performance

    Layout is very easy to get around.

    90A VRM with active heatsinks


    Cons

    Memory speed lacking on Samsung B-Die ram (4400mhz limit)

    Front panel connector position

    Voltage limitations

    On-Board LED position is odd and just can’t be seen



    [​IMG]



    Price is around the $420-480AUD mark making it a very competitively priced performance motherboard to rival the larger ATX varieties in some circumstances.

    Good memory latency just like its older generation boards just as expected, I am curious if this board still suffers from the tight memory slot spacing as my Z390 Phantom Gaming ITX scratched all the high end memory kits I installed which all have very thick heat spreaders :mad:

    They are tight mate, but there was no issues with the extra thickness of the Royal's in there.
    Most of these ITX boards have more issue with how close my AIO cooler gets to the RAM with the outlet pipes touching the spreaders.

    Despite the fan, it's nice to see a bona-fide fin array on that VRM heatsink!

    Good write-up mate, thanks for sharing. Big fan of your work :thumbup:

    Thanks for this review,
    I have the same board and the same m.2 ssd, sabrent rocket 4.0 1tb. Trying to install a fresh windows 10 on it, but when going to select the drive to install w10, sabrent rocket 4 doesn't show up. Any thoughts?
    Cheers

    Are you using Rocketlake mate?

    If you are, you need to run from the slot that comes from the PCH, not from the CPU. Common on Z490, think so anyway.

    Hmmm

    Has anyone maanged to get Pci express 4.0 going on this board..

    the 6600XT i have, will only link at PCe express 3.0, despite trying to force pciexpress 4.0 in the bios.

    similarly the WD black 850, will only do 3.0 speeds in either M2 slot.

    all confirmed with GPU-Z and WD dashboard and Crystal diskmark..

    Wasted a couple of hours, tyring every configuration I could think off..

    so since release, they released a bios for pcie 4.0? obv with 11th gen CPUs only.

    Dont need to ask kelvin but you not using a 10th gen CPU in it are you? lol...

    I have a solution for you. Sell, get a X570 Strix itx, be done with intel :p

    BTW great write up :) (aware its over a year old)
