CPU Cooler Fit and Included Accessories
CPU Cooler Fit
To test the amount of space surrounding the CPU socket, we mounted the Noctua NH-D15 cooler to the CPU socket. This behemoth CPU air cooler sports a dual fan construction and two huge vertical cooling towers.
When oriented in its default configuration, the Noctua cooler fits to the Strix X99 Gaming motherboard without issue. The cooler has adequeate room along all sides and does not conflict (space-wise) with either the DIMM slots nor with a card seated in the primary PCIe x16 slot.
The closeup views of the cooler seating and mounting further display just how well the Noctua cooler fits to the board. If a cooler as large as the D15 can fit on this board, you should have not issues with anything.
The Noctua hold down mechanism is large enough to quickly determine exactly how much space is available around the CPU socket. The Noctua mounts fits the socket well with no tight areas or contact points evident between it and the on board capacitors, chokes, or heat sinks.
Included Accessories
The Strix X99 Gaming motherboard comes with all the necessary components to get the board up and running, as well as some nice to have accessories to further customize the board's look.
The manual included with the Strix X99 Gaming does not disappoint, written in the clear and detailed language we've come to expect from ASUS motherboard manuals. Also included is a driver DVD with all necessary hardware drivers and Window's utilities, ROG case badges, and ROG case labels. The case labels can be used to label SATA cables, hard drives and SSDs, as well as Keybot-related function keys.
The board's rear panel shield consists of a chrom surface with the port identifying text and icons printed in white text on its surface. Under good lighting, the text and icons are easy to read, but would be challenging to see under poor lighting conditions.
ASUS bundled in four black and white 6Gb/s rated SATA cables for use with the integrated port. The cables have integrated port locks and a mix of straight and 90 degree connectors.
For multi-GPU use, ASUS included a single two-way NVIDIA SLI cable.
For use with the on-board front panel header, ASUS included one of their Q-Connector header plugs. You simply plug the front panel case leads into the Q-Connector, then plug the Q-Connector into the appropriate board header. It makes the installation of the front panel plugs much easier.
For use with the integrated WIFI adapter, ASUS includes a dual-plug antennae with gold-plated screw-in connectors. The antennae can be used in a flat or upright orientation with its flat surface optimized for broadcast and reception of 802.11ac type signals.
ASUS included a CPU installation tool with the motherboard to ensure easy and proper CPU installation into the board's socket. You simply snap the plastic guide over top of the CPU and place the CPU in the socket with the "This Side Up" arrow placed near the socket hinge. The plastic guide remains in place when you lock the CPU into the socket.
For use with an external RBG LED strip, ASUS included an extension cable that plugs into the board's RBG LED header for powering and syncing the external strip with the board's illumination settings.
To better support a variety of user illumination settings, ASUS included three additional chipset and rear panel in-lays in addition to the factory installed red colored in-lays. The additional in-lays come in white, pink, and yellow.

























Can both the U.2 and M.2
Can both the U.2 and M.2 ports be used simultaneously?
It looks likes you can, but
It looks likes you can, but M.2 is favored over U.2. In the BIOS, you can specify two use one or the other as well.
Yes, but the manual for this
Yes, but the manual for this motherboard says it shares bandwidth with the M.2 slot.
In fact most things are shared (WiFi, USB3.1) if you only have a 28 lane CPU.
yes you can.
yes you can.
Would you know if ASUS will
Would you know if ASUS will be revising their X99 MICRO ATX motherboard?
Saving for the ASUS X99-M WS and will make the purchase by the end of the year. But would be nice to know if a newer board will be released then which includes various improvements as seen on the other boards.
I am not sure, truthfully,
I am not sure, truthfully, but have not heard of a revision coming out…
I have this motherboard along
I have this motherboard along with Corsair LPX 3200MHz, 4x16GB modules.
The issue I have with it (and if you read a lot of newegg reviews) is that the board will not post above DDR4 2400MHz with this memory. Is it just the size of my RAM and compatibility?
When it doesn’t post, the only way to get it back is to unplug it, remove the battery, and clear the CMOS. Then you have to hold the power button for 20-30 seconds. Then it posts.
It’s ridiculous and I can see why so many newegg reviews claim it doesn’t boot after a week.
Did it pose any problems for you?
Right now I’m running it at 2133MHz just because I’m tired of it not turning back on if I shut it down.
It’s weird though because I can get it to boot at 3200MHz after it successfully boots at 2133MHz. Until I shut it down. Restarts are fine. And sleeping is fine.
I had a hard time dialing it
I had a hard time dialing it in for overclocking and did notice an issue getting high memory speeds to work, but was able to get similar corsair modules to boot and run stable at 3200MHz. My testing was done with a Haswell processor.
Were you using a Haswell or Broadwell processor in your system?

Thanks. 6800k in my system.
My system actually runs stable at 3200MHz memory using XMP, along with a 4.5GHz on all cores at 1.370v (I won the silicon lottery?). I played around with the cache multiplier, but that didn’t make a difference in it booting.
Everything else is basically set to auto voltages.
The issue is simply that it won’t boot with the RAM at higher clocks from a cold boot. With a warm reboot and it’s fine.
I didn’t buy a 4x16GB kit, rather 2 kits since it was cheaper.
That’s an odd one. I did
That's an odd one. I did have quite a time getting the board to board with RAM at 3200MHz, but, it did eventually once i got it dialed in (without using the XMP setting too).The board itself is just a bit "finnicky", but that may have more to do with the changes made to support the Broadwell processor perhaps. Didn't have the same challenges with older X99 boards. (Note that this is speculation on my part based on testing experiences, and not based on anything I've heard/been told by ASUS or other manufacturers).
One thing to check is the BIOS version, make sure to update to the latest if you haven't already.
One other thing, Raja from ASUS put out this very comprehensive guide on overclocking the Broadwell-E processor on X99 boards, that also includes memory tweaking. I found it very useful myself:

The thing is (and I’m a Strix
The thing is (and I’m a Strix x99 gaming motherboard owner) that this board is marketed as an overclocker’s dream, but in actual life it’s the furthest thing from it.
It seems to have issues even at factory settings, it’s quite choosy about RAM, and it has a delicate voltage regulation circuitry – I’ve had to RMA it AND my CPU after the dreaded QCODE 00 hit my board one morning a few months after assembling my rig. And I know that others with this model encountered it as well.
Now I’m pretty stable (the board alternates between Qcode AA and Qcode 40 most of the time) with the latest bios, and a UPS unit to make sure that there are no spikes. But I would think twice about buying a board from this series again. Even the newer x299 LGA2066 model. Just my two cents.
Hello new here
I have this
Hello new here
I have this motherboard i have purchased a msi gaming x TRIO 2080ti and wanted to get another. However it wont fit two cards the the x16 slots ie top and middle pcie slots. if i was to add the second card to the bottom pcie slot would it still link as x16 or x8? as u can probably tell im not spend another 1300 on a card if the wont link at x16 on both cards. any help would be much appreciated.
Thank you in advance.
THIS IS A FANTASTIC BOARD BUT I DO GET THE ODD OVERCLOCKING ERRORS EVERY NOW AND THEN
