ASUS Z77 Motherboards - Official Support Thread

GroktheCube said:
I'm having an issue with my P8Z77-V pro. It will not post if there are DIMMs in B1 or B2. The red dram led remains lit. It works fine with A1 and A2 populated. I've already tried clear cmos. Should I bring it back to microcenter for an exchange, or is there some BIOS setting I'm not seeing that's needed to activate the other two DIMMs?

Your mobo might be perfectly fine. It seems like asus z77 problem, the same thing happens on Maximus V mobo and some ram sticks. Apparently Asus HQ is aware of it and they are working on the fix. I'm awaiting for Samsung RAM to arrive to test my maximus board For more details please this thread...

Raja@ASUS please correct me if this information is incorrect.

So the temporary solution is to only use half my memory? Now it seems to be giving me a hard time about ram in any slot other than a1.
 
Hey there Raja I am having an issue with my lan controller which I have brought to your attention before but we found out that it was my netgear WDNR 4500 because I connectede my computer directly to my modem and used two diff cables also tried diff ports on router. Well seeing as how awesome netgear support is I figured that I wouls just order a wireless mPCIe card for use with the maximus V gene that I have. My issue is that I cannot see any wireless networks... I have the latest drivers installed and win 7 found the card immediatly (upon first installing the pci to pci bridge(I assume that this was necessary for the standoff mini card)). I however do not have any antennas connected to the mobo or the standoff card or the tiny wireless card... Is this my issue? the wireless card that I got was this: Intel centrino wireless-n 1000 . So if that is my problem and I somehow need to connect antennas to this tiny guy where or where do I get those antennas from?

Thanks for all your efforts thus far!

"those" manufacturers have to validate it fully otherwise we get complaints that this or that will not work (some vendors dont mind that). The information I supplied on previous chipsets was correct, this time I think if it were possible it would have been added already. I will ask HQ again tomorrow morning and see what they say about it.

Raja@ASUS said:
Well We will wait until validation rather than making a claim that it works without checking all items - some vendors didn't bother and if you think that makes things better then we should agree to disagree. As I said earlier we were right with Q series on the last gen, so if all 50 tests don't pass it is not valid. As I said I will ask HQ again tomorrow and see what they say.

This Intel page Desktop Boards Compatibility with Intel® Virtualization Technology (Intel® VT) lists several Intel Z77 motherboards with VT-d capability.

This test report from ASRock VT-d Test SOP verifies VT-d functionality by configuring an ASRock SandyBridge motherboard, installing VMware VSphere, and checking configuration. Admittedly H67 is not Z77; Z77 is a die-shrink of SandyBridge.

ASRock Z77E-ITX User Manual p.49 Section 3.4.2 North Bridge Configuration:
VT-d
Use this to enable or disable Intel® VT-d technology (Intel® Virtualization
Technology for Directed I/O). The default value of this feature is [Disabled].​
Either it works or it doesn't, or it's a crock. Personally I doubt they'd list it unless it's at least supposed to work. With enough complaints eventually ASRock will make it work.

At any rate, absence of VT-d is a show stopper for me. If Asus HQ states VT-d is not available for their Z77 boards, I'm more inclined to purchase an ASRock board.

Stop the press! Asus P8Z77-V compatible CPU's page imply the motherboard supports VT-D.

Update: I flashed to the newest BIOS on Asus' site (1015 IIRC), reset CMOS, and I'm now running with a full 16GB! The memory is Kingston Hyper-X DDR3 1600, and it seems to be working just fine with the newest bios.

hum...last gen ? z68 chipset works as tested here

or here :

http://www.overclock.net/t/1200725/vt-d-is-your-friend-a-success-in-passthrough-to-xen-hvms

Code: 
Some info on my setup:
Intel i7-2600 (non-k ) -- VT-d only available in non-k or intel Vpro capable northbridges
ASrock H67M-ITX -- ASrock is awesome because they have enabled VT-d in a lot of the new UEFI capable 1156 and 1155 boards
Xen Hypervisor (4.1.2) Running a Fedora 16 x86_64 dom0
Passthrough done with a work-around with virt-manager to release the PCI resources, xm pci-attach to reassign

VT-d is incompatible only with Asus boards it seems :eek:

All 50 tests do not pass on anything but Q series. So you can believe that if you want. You can enable it, but it does not mean it works in every test ;)


Update on Z77 from HQ, all tests will not pass so we will not claiming support like other vendors. You can obtain Intels Vt-D verification tool and test for yourselves

I would do a google search for antennas my friend, that card can take two it seems. They usually click or screw into place.

Do me a favor, switch off at AC, remove the CPU from the socket again, this time clear CMOS with it removed. Replace, and try again, see if that works. HQ said that when they have seen code 55 reseating the CPU works 100% for them.

Note on that page all the core i7 3770 CPUs except the 3770K feature VT-d. I'd be a little leery if Asus HQ were to say, "The P8Z77-V does not support VT-d" since that statement would refute Asus' claim of compatibility. Either the entire feature set is supported (compatible) or the entire feature set is not supported (not partially compatible: not compatible).

This is pathetic to say the least ! Even intel advertise their OWN z77 motherboard (DZ77GA-70K, DZ77BH-55K) compatible with vt-d. I would not be surprised through if the test program would fail on purpose on anything but Qxx, just to sell thoses chipsets ! real life tests show that VT-d works fine with Asrock, so the problem is within Asus. You could have AT LEAST released some beta bios to let users the choice.

Anyways, I've just ordered an Asrock motherboard with an i7 3770 and I would certainely not coming back to Asus anytime soon.

Thanks for your time.

You wanted the real info so I asked and that's the info I got. It does not benefit me to make up stories in this thread. I do not write the lists you see, nor am I in contact with those that do.

Either way, I still see what I do as support as I would rather someone knows what they are getting and makes a purchasing decision accordingly - even if it does make them somewhat mad/angry.

-Raja
 
Another disappointment, besides the VT-d issue, is that the recent EFI update disabled the MS interrupts (Message Signal Interrupts) for the PCI express ports. Grrrrrrrrr....

Raja,

With all due respect I write this sober (not mad or angry) reply. This isn't personal. I'm sorry if some respondents appear to want to shoot the messenger; that gets us all nowhere.

I suppose your creating this support thread has the sanction and therefore the attention of Asus' senior management. It would be a waste of valuable market feedback otherwise: The [H] thread "Official ASUS BIOS and Program Updates" received close to a million views since inception. This thread received close to 8,000 views since its inception 3 weeks ago.

You might report then "the natives are restless". There appears to be a contradiction:
  • On one hand there is Asus HQ saying the Z77 Express chipset fails Intel's VT-d validation testing, therefore Asus does not include VT-d control in the BIOS.
  • On the other, Intel itself along with other motherboard manufacturers advertise VT-d functionality for their Z77 Express motherboards.
I think it unlikely Intel and the others have brought to market Z77 motherboards which fail VT-d validation. Be that as it may one user, maybe more, have decided to not buy Asus as a direct result of this thread. The ball is in Asus' court to deal with.

I for one would be disappointed to choose another manufacturer. Other than this VT-d issue I very much prefer Asus P8Z77 motherboards.

Any help would be appreciated, thanks.
 
Have a Z77 Sabertooth and 4-pin PWM fans connected to every header except nothing on the CPU_Opt and the Assistant fans connected to the assist headers.

Have tried just about every combination of settings, but can't get any of the case fans below 1000 RPM. They are Arctic Cooling 120mm fans with a min of 300 RPM. How do I get the case fans to operate in PWM mode or at least tell the MoBo that the min is 300 RPM?

Using the latest BIOS revision.
 
Last night I built a new computer using Asus's Sabertooth Z77 and the new Intel i7 3770k processor. Today, my gtx 560 arrived in the mail, but I'm still at work and haven't been home yet to install it. Last night, before going to bed, I got my new computer running and was using the integrated HDMI output on the motherboard to display on one of my two monitors.

My question is this: after installing the gtx 560, when I choose to display on both of my monitors, what configuration of video outputs should I use? Can I use both hdmi outputs (one on the mobo, another on the video card) or should I stick with an hdmi/dvi output combo strictly from the video card?

(If it's relevant, the Intel Integrated Graphics driver isn't installed yet. I only installed the LAN/ethernet driver last night before bed.)

Thanks in advance :)

This brings up the point of which one Sabertooth Z77 owners should use - Fan Xpert 2 or Thermal Armor?

Fan Xpert 2 calibrates based on min/max fan speed, allows you to adjust the speed at which the fans spin up or down (very much like this), but only allow you to map the speed back to CPU temp (which is utterly useless)

Thermal Armor doesn't have any of the calibration features Fan Xpert 2 has but allows you to create a custom map to up to 3 temp sensors for an effective temp. I very much like this.

Why can't Sabertooth owners have both? Both sets of software work on the Sabertooth, but I haven't figured out what makes one take over vs the other.

Raja@ASUS,

hope you come up with some positive answers (and an official announcement from asus would be good) soon! i was getting ready to order my m/b for an ivy home server build when i realized this problem and it is a deal breaker as the main purpose of such a server is to run multiple VMs (quiet a few with 32GB ram) as efficiently as possible!

i have exclusively been using asus m/b for nearly 20 years and would hate to be switching to gigabyte (their GA-Z77X-UD5H provides support) for this one issue :(

Hmmm, this is interesting, as I was not aware that FX2 works on the STZ77. I don't want to use it, however, because I feel the capability to calibrate PWM fans and link them to thermal sensors other than just the CPU should have been an option built in to the Thermal Armor program. I feel as if Asus has short-changed us ST owners. :mad:

I don't really feel shortchanged, but I do think it was slightly lazy to come out with Fan Xpert 2 but not update Thermal Armor with those new features.

ST is a premium board in my book. It should be able to do everything the other high-end/premium boards can do in regards to something simple like PWM auto fan calibration. No excuses for it not to, imo.

Hominin,

I think we may be running into "market segmentation", courtesy Intel. That is, you wanna build a server, we got you covered with server chipsets & motherboards.

The VT-d validation I'm willing to accept is if VMWare VSphere sees virtual directional I/O.

There's a 30 day free trial period. I wonder what it will say.

Harry

P.S. 'Course it would be cool for Asus to give us the damn switch for VT-d. Call it beta BIOS.

Oh, sorry, I misunderstood. Thanks for the help.

sorry, i lost you there a bit :confused: based on comments from others here and some research of my own, there are manufacturers who are making vt-d enabled m/bs using z77 chipset which means the chipset is vt-d capable, which in turn makes it a failure of asus to provide the feature on their z77 m/boards, not an intel thing.

the gigabyte case also partly dismisses the 'some manufacturers don't bother with the validation argument as its only available in some of their (high-end) motherboards so they're not labeling non-capable m/bs as capable

i'm really torn here :(

there are more people in that conversation now Raja :p

that is a very disappointing response; who is your source? marketing, n level support etc?

there has been some very valid points raised here; is anyone at asus checking how other brands are able to provide vt-d support on the z77 chipset (i.e. get one and run the validation yourselves on it)?

which parts of the validation are failing on z77 (most of your comments were re z68)? can it be partially activated?

the low power use of ivy bridge makes it an ideal choice for home servers, that is a massive chunk of the m/b market you're dismissing with half research/replies!

main thing i'd like to know is are you guys at least working on it or will you be maintaining a "nope, we won't provide it" attitude?
 
Well it turns out installing Inel rapid start is what breaks Coretemp on the P8Z77-I Deluxe. Nothing like this happens with the Asrock Z77E-ITX and I narrowed it down after several Windows installs. Lastly, and this must be a problem with the Intel drivers, external drives plugged into the Intel USB 3 (backplate) do not mount after restarting Windows nor are they fully detected during boot up.

Sorry, total speculation on my part that Intel would influence Asus to not declare their boards VT-d capable. I'm unfamiliar with Gigabyte's line-up so this is also total speculation: The Z77 Express chipset can handle VT-d. Gigabyte may be doing their own market segmentation via BIOS in their series of Z77 Express motherboards where some are VT-d capable and some are not.
 
I have the P8Z77 -V LK

If this has been asked already i apologize.

But when i plug in USB devices they arent detected all the time.

Or i'll reboot my computer, and the USB device that was working at first now has to be re-plugged in or if that fails moved to another port.

Im using the latest BIOS.

Any ideas on this problem?

I mentioned this above, but it still hasn't been answered. This only happens with the Intel USB 3 on the back with the P8Z77-I Deluxe. I've seen this happening with an Asrock Z77E-ITX as well (Intel USB 3), so I'm guessing it must be a driver issue. No Bios/UEFI detection and needs to be re-plugged in as you mentioned. Is this happening with USB 2 ports as well?

Edit: Oh and again, I'd love to know why Intel Rapid Start installation breaks Coretemp (APPCRASH) on the P8Z77-I Deluxe, while this doesn't happen with an Asrock Z77E-ITX.
 
This will be my last response on this unless anything changes.

Does not matter how many people ask, the fact remains that all tests will not pass and at this time we are not interested in offering a partial solution. Just like we did not on P67.

My source works with R&D and the BIOS teams is situated in HQ. When I say works with, I mean both physically in presence and in job detailing.

My 4 USB 2.0 ports on my back give me issues, my front panel seems to work all the time, i don't know why.

Had to plug my KB into my 3.0 plug and it worked the first time, only time will tell if it has issues too i guess.

My only gripe with this MOBO so far, everything else is solid.
