ASUS X99 Motherboard Series - Official Support Thread

what happen exactly when it hangs?
when it hangs? before starting windows? during windows loading, when?

I have since done an RMA and the new board seems to be problem free for now, I will report back if problem comes back. Seems I had a faulty board.
 
Just FYI I had some odd boot problems on my Rampage V, about every 6 boots or so it would give some damn qcode (usually but not always in the 60's) and I'd have to cut power until the mother board lights went out then it would boot normally. I went through all the usual 'it must be the USB' (one good thing I got a $30 USB 3 card that's twice the speed of the onboard USB 3).

Well I finally traced the problem down to an out of spec DisplayPort cable to my 4K monitor. I won't go through how I finally figured that out, but replaced the cable with a certified display port cable and have not had one single boot problem in the past month.

So USB is probably getting the blame for some things it's not responsible for on the ASUS and other x99 boards.

Interesting, I might have the same issue. When connected to my 34UM95 via DP I get random boot failures, but when connected through my TV (HDMI) it *never* happens. Didn't think it would be the cable - I'll have to try a new one.
 
This can happen if the DP cable is built out of spec. Pin 20 should not be connected - unfortunately many cheap DP cables connect this pin which results in 3.3V leaking back into the board from the monitor.

I have the same problem with a perfectly standard cable made by Eizo.
My cable is listed in the "Display Port official page" as a compliant camble to the display port standard.
I don't understood if this problem depends on Maxwell architecture or on mobo.

the issue occur with several model of cards in the market, and its brand or architecture agnostic. one of my machines had the issue using AMD cards. even if the cable appear there, just test with another new one and see how it behave.

I have tested three cables, two of this was DisplayPort certified.
 
another problems, with asus it never ends.

I noticed that the latest 1901 BIOS for my X99 Deluxe makes my cache voltage "go up and down" as if I set adaptive in previous bios.

With previous BIOS the cache voltage was stable if set to use offset, now it varies with CPU load also if I set it to offset.
Is this normal?

I noticed this same issue with my Gigabyte X99m, 780 Ti SLI and the LG 34UM95. After lots of testing it seemed to be related to UEFI GPU vBIOS and/or DP 1.1. After I enabled DP 1.2 the system would boot normally, although I noticed that with DP 1.2 sometimes the LG will lock up and display corruption on half of the monitor. A quick power off/on and the corruption disappears, this was very infrequent also.

this is a common problem on this motherboard, I don't understood if it is a maxwell problem or an asus one,
 
the option in this menu:

1000


is disabled and grey out:

1000


is it normal that my NVMe bios setting is disabled also if I'm using a Samsung 950 PRO M.2 drive?
 
Just installed this mobo with an i7-5960X CPU and 8 x8GB G.Skill Ripjaws F4-2800 memory modules. PSU is Corsair AX-1200, known to be good.

Video card is Zotac GTX 980Ti installed in PCIe slot 1. Turn on the power and QQ code shows 00. The mobo, video card, fans all work but nothing happens. The monitor shows a black screen and there is no signal on the DP, DVI or HDMI ports.

I then moved the video card to PCIe slot 3 and tried again. Same result, nothing.
Then I changed the video card to an EVGA GTX 680 (known to be good) and repeated the operation in PCIe slot 1, 2 and 3 and on DP, DVI and HDMI ports and again the same result, nothing.

No Asus logo, no way to enter the Bios. It does not even start Post.

Should I return the mobo?
 
take all but 1 stick of RAM out and try to get it to post, make sure vid card is in the top PCIe x16 slot, if it does post then you need to flash the bios and go from there.
 
That did not work either. Still no way to get into the Bios.

Check for bent pins, recheck all your connections

Most of the time when things do not work it is human error, but if you have checked everything then you might have a bad board, RMA it.
 
Checked the socket and nothing appears wrong or bent. The only connections are two Noctua fans (that work OK) and the 20 and 8 pin power cables. Looks like a DOA board. I'll start the RMA. Thanks for your help.
 
Harm,

I'm sure you know this, but I was shocked to find that myCorsair power supply (1200AXi) uses proprietary cables. I had similar problems until I used the ones that came with the power supply (BTW: many thanks to you for all I learned from you in the Premiere Pro forum).
 
I was indeed aware of those potential idiosyncrasies, having suffered from different power cables to a video card in another system, several generations ago. But this not the case now. I only use the original Corsair cables. Anyway, I have repackaged the mobo now and will be exchanging it with another one tomorrow.

Don't thank me for my time on the Premiere Pro forums. It was a really fun time and I enjoyed it tremendously. If you are still interested in my endeavors, you may want to take a look at http://ppbm7.com/index.php/new-system-build and http://ppbm7.com/index.php/tweakers-page
 
Raja, using the 2001 bios on the X99A/USB 3.1, the fans spin really loudly on reboot before quieting down when Windows loads. Much louder than the 1901 bios, with the same settings which is basically all fans set to manual and minimum speed in the bios.

asus fan expert never worked well.

This is probably when the driver loads and the system hands off. Would not worry about it.

I'm aware of what happens regarding Windows taking over and silencing the fans, it's just that the boot up fan noise is much louder on this bios, sounds like the system is really straining itself. Probably no big deal just wanted to mention it.
 
There is no real strain in the electrical sense - the headers are regulated.
 
Hello everybody,

I've been experiencing a very strange problem for few weeks now, and didn't manage to find any solution. To be as clear a possible, I would say that when I launch a game (namely GTA 5), my 5960X (on X99 Deluxe) runs perfectly at 3GHz for few minutes, and then, I don't know why, switch to 1.2GHz and never come back to 3GHz again. As you can imagine, the consequence is instantly visible : framrate drops from 60fps to 20-25fps, and the 290 GPU is no longer able to be 100% used...

I don't have any way to make it go back to 3GHz except to reboot the computer... (even with OCCT, the CPU doest go upper than 1.2GHz). I checked a lot of things : this does not seems to be linked to temperatures (as they never exceed 55° when the problem happens...), I tried to disable the boost thing in my BIOS, I also tried to disable speedstep and even C-step states, same results, it starts at its native frequency and then drops to 1.2Ghz and never go back again... Also tested another PSU when having a Q-Code 00 (after rebooting to recover the original frequency...), it didn't fix it, so I guess the PSU is not concerned by the frequency drop neither...

After that 1.2 Ghz stuck, when I the computer, the boot is hard to get : lot of blackscreens at boot (Q-CODE 00 = Not used !), sometime several times until it decides to boot again. More even strange : I don't think I had this problem previously (I think I would have noticed this horrible frame drop before, and same when I used OCCT to test a bit OC...), this started few ways ago, after some weeks of unactivity, so I cannot remember when excalty it happened and why (if there is a reason linked to me...)

I'm quite frustrated and I really have NO IDEA what to test and what it is about. I'm pretty sure this 1.2GHz thing is a kind of security thing (because it is always 1.2GHz, this is not random !), and someone who really knows how those MB and CPU work can understand what's going on, I guess... If any of you have some suggestions, I would be glad to read it...

Thanks !

I had same problem when overclocking, now problems is solved on the rig in signature.
I don't know it was solved by a bios update or by some setting that I use to use in bios.
 
nandayo: in addition to disabling c-states and speed step, did you set windows power profile to 'high performance'? That should prevent downclocking of any kind.
 
I have always been in performance mode in Windows 10, yes. I tried BIOS update also, didn't change anything : after few minutes of load, go back to 1.2 Ghz (idle frequency if I am not mistaken).

I'm really desperate !
 
Raja, I looked around on line and found references (and BIOSes) to the X99-E WS. However, does the X99-E WS / USB3.1 board have official support for Intel 750 nvme drives? (Only thing I see is a generic mention to PCIe SSD's in the latest BIOS, assuming this is nvme?)

Thanks in advance!
 
New 2001 BIOS for X99 Deluxe.
As always, there is no changelog from Asus.

That's really bad coming from Asus. They are quality boards but they never provide a log with their BIOS updates compared to other Taiwanese board manufacturers.

they don't want to admit errors, our motherboards are full of dirty workarounds.

my deluxe isn't able to use the optimized phase since a bios update, now the phases are set to extreme no care what you set in bios.
this results in hotter VRM also when in idle and some more watts on the AC.
this was a dirty workaround for deluxes that goes up in smoke some months ago.

this is the only dirty workaround that I seen with my personal experience, who knows how many others are there.
 
Just put together my rig with a X99-A USB 3.1 and an 5820k. Threw in 32GB Patriot 3000mhz ram as well occupying 4 slots. I have two issues.

  1. All sticks are not always detected at boot. At first I was getting only 16gb reported. Then it booted with 32gb reported. Then yesterday I booted up and it decided it only had 24gb. I also have them running with really loose timings and lower than rated speed. Selecting the XMP profile will stop the machine from booting.
  2. Asus AI Suite III will not install no matter what I do. I haven't had any prior asus software installed on the machine. It is Windows 10. Tried running as administrator and compatibility modes with no change in behavior. I am able to see that it reports some kind of com error before closing the install windows.
