I talked to Intel tech support on chat. He asked me what size my HDD's is. I said 120GB and he replied that on Intel motherboards, UEFI boot only works on +3TB HDD's.

Can anyone of you confirm it? Are you using a HDD less than 3TB and using UEFI boot?

Rubbish. UEFI works so long as your harddisk is big enough to install the Window 7. You no need 3TB harddisk for UEFI.

Hi,

I've had the same issues with hardware in Device Manager suddenly
appearing unsupported and the Windows Experience Index not functioning, traced to enabling UEFI in BIOS, but have since (0035, although currently running 0039) left it disabled waiting for a fix (Intel, are you listening?).  I’m running a 120 GB Intel 520 SSD, setup as AHCI, so I don’t need UEFI for over 2 TB disk support, but would like the fastest possible boot performance. 

On another issue, when I power on my system the (Intel 3770K Retail box) CPU fan initially speeds up to an annoying level and then calms down to barely audible (normal) speed.  I have not found any way in the BIOS to address this. With the numerous issues I've had thus far, and the many apparent BIOS instability issues with this board reported elsewhere here (Intel Community Support), I'm not sure if this is normal behavior.

What's your experience with the CPU fan when PC is first started?

Thanks,

The CPU fan will spin up very fast at boot up for a short while and slow down. I had spend over 2hr at the phone with the technical support officer. The diagonistic should have ended when the bios cannot detect the UEFI harddisk but she insisted to go through the whole reformating thing and I even need to do a force boot to test the motherboard. Even now after going through all this verification, she still need to simulate this issue before she escalate to the kingpin Bios Engineer.

I told her, why not email straight to the bios engineer to request for a list of unresolved bios issue. If such a issue exist since others who had similar problem will also will have launch a complain then we can save our 2hr of time troubleshooting over the dame phone. However she think otherwise and she did not wish to disturb the bios engineer and insist on follow the following proceedure :

Technical support officer (TSO) troubleshoot with user over the phone (wasted over 2 hrs on the phone). If issue cannot resolve the TSO will try to simulate the same problem in her lab (wasted hrs simulating the problem) and if she succeed in resolve the problem she will inform the end user, if not she will then escalate to the bios enigneer (BE).

I suggest to the TSO why not email direct to the BE to ask for the list of unresolved issue. If UEFI is one of the unresolved issue then just admit it over the phone and save everyone's time. But she insist not to disturb the BE and we had waste hours doing all the useless troubleshooting (from the initial part I already know the bios problem cannot be resolved) I just play along with her to see what she ask me to do for that 2 hrs of troubleshooting.

Hi,

I, too, have spent many hours thus far with this board and would think that even TWO
customers reporting the same or similar issues should be enough to indicate the
problem(s) is on their end with the hardware and/or BIOS and needs to be timely
addressed by the technical staff.

For the moment, I am waiting to see what happens
with the next BIOS release.

Thank you for your input on the CPU fan speed at startup!

Regards,

I installed Windows onto a 500GB sata drive with RAID mode and UEFI enabled. Just put in the disk and it worked just fine. (Server 08 R2 but Windows 7 / 8 should work the same way, I had also put Windows Server 8 on it) I'm not sure if that's a bios issue you guys are experience or if the board itself is broken. I RMA'ed mine because it would not detect a PCIe card I put into it. When I get the replacement I'll double check and see if I can still install with UEFI before installing again without it. If my new one still works fine I would probably suggest just doing an RMA as that particular board might be faulty.

I'm intersted to know how you make out with replacement board.   RMA through Intel or Retailer, and if through Intel, a Refurb or NEW board?

Thanks for your input!

So you are using UEFI Boot on a 500GB HDD? What motherboard do you have? How did you do to make it boot in UEFI mode? What settings do you have in bios?

I will chat with Intel tomorrow again and point them to your post where you claim to boot using UEFI on a 500GB HDD. Will see what they will say since they claim Intel motherboards can only boot on 3TB HDD's. I chatted to 3 different tech support persons yesterday and they all told me the same thing.

UEFI is required only when the hard drives are 3 TB or higher so it will only work under those

circumstances

My PCIe card also cannot be detected on my Intel DH77EB. May I know the model number and brand of the PCIe card you are using ? So have you gotten your replacement motherboard and can it detect your PCIe card now ?

Did Intel give u a brand new or refurbish motherboard ?

I noticed something now. Since i did no't manage to boot UEFI installed Windows using UEFI boot mode i tried to install Ubuntu and see if that would work but i only get a black screen. When i restarted to boot Windows again i forgot to turn off UEFI boot so it booted into a non UEFI installed Windows and i got the same error as you

“! PCI Simple Communications Controller”  error in device manager

I thought this only happens on a UEFI installed Windows but no. It happens on a non UEFI installed Windows when you enable UEFI boot in bios.

I think you understand what i mean. So its not worth to even try to install Windows in UEFI mode because some things will not work. Lets hope future bios updates will solve issues.

I bought my board through Newegg.com, so I used their RMA process. It was within 30 days and as far as I can tell it was a new board. I believe that Intel wants you to handle the RMA through your retailer and not through them.

@dislikeyou: I have the DZ77GA-70K. I came here when I was experiencing issues with the board. Sadly, I installed the new board last night and I still don't see my card. The PCI Simple Communications Controller is part of the Trusted Platform Module. If you do not want to use the TPM functionality then you can simply disable that device. I've disabled it on just about every pc that I've ever seen it on and not had issues. I really don't know why Tech support would think that UEFI requires a 3TB hard drive. It has nothing to do with the size of the drive. I bet most new laptops are using UEFI for booting now and I definitely don't know of laptop with a 3TB 2.5" Hdd.

@playst: I'm using a Hauppauge HVR-2250, it's a tv tuner card. It does't seem to matter what slot I put the card into it doesn't appear in device manager. I installed it into a Sandy Brige pc with a P67 board and right away it shows up as "multimedia controller". Ran the installer for the drivers and everything works so I know the card is not at fault. I might attempt to put my i5-3550 into that board but I'm not sure if it has a bios update for Ivy Bridge or not.

bman, but did you install Windows in UEFI mode, and did you manage to boot it in UEFI mode?

If you did, can you be kind and tell me how you did. What hdd's do you have and did you have to enable/disable something in bios to make it work? Should it show "UEFI:" before the HDD name in the boot list?

Edit: Could you be kind and do me a favor?

and check if it is showing wrong cpu speed for you. Must tick "Show CPU Clock" and "Realtime Clock" in options

I want to know if it is not working properly with Intel motherboards or it is just me.

Thanks

Hmm... I'm really confused now as to what was going on before. I know that I installed something onto a drive as GPT partitioned. I don't see the UEFI in front of my boot drive, and after I installed a beta of Server 2012 it would not boot it. I did have enough drive space hooked up at one point to qualify for the 3TB of disk space, so maybe it did some weird stuff with that enabled. (I didn't install to those drives) It's possible I was mistaken that it did install with UEFI seeing as how the option was checked in bios. It's also possible that I was using the 0035 firmware when I did the install and not 0039. (I'm almost positive that I was using 0035 the first time I was installing.) I've tried 3 different OSes and none of them will boot after the first part of the install now. I specifically recall being able to boot a drive with UEFI enabled in BIOS, but it wouldn't boot if that was unchecked. I can't boot any of the installs I did now regardlesss of UEFI or not. Here is a link of someone even showing installing onto a 500GB hdd using UEFI so I don't think I'm completely crazy. http://www.eightforums.com/tutorials/2328-uefi-unified-extensible-firmware-interface-install-windows-8-a.html

Perhaps Intel locked it to 3TB+ in their latest firmware update? At this point I really don't know what is going on so maybe I was just dreaming or something...

I installed that gadget onto Windows 7. Using an i7-2600K on the DZ77GA-70K it shows the clock speeds correctly. Using the i5-3550 it does not. Even CPU-Z didn't seem to report clock speeds correctly as it should have been downclocking just sitting there. I would say once they update the program for Ivy Bridge it should work just fine.

BTW, I am taking this board out and returning it. The board is way too flaky right now and it doesn't want to work with my card. There were also issues with it hanging after reboots and just shutting itself off, and it would also turn itself back on even though I turned it off by holding down the power switch. Sometimes I would see options not take even though I unchecked them. I couldn't turn of execute disable bit from normal mode, it only worked in classic. Hopefully they will push out some firmware updates to give you guys something better to work with. I wish you guys the best of luck!

I use a Seagate 3TB harddisk, enable all the UEFI setting and that DH77EB die die also cannot detect UEFI.

My DH77EB also cannot adapt to the PCIe TV tuner card and cannot detect it.

Till now Intel representative is still in denial and try to smoke their way through by saying I am the only person in the world with this 2 issue for their latest 7 series motherboard ..........

I saw the Rrelease Notes for DH77KC, DH77DF BIOS 0095.

And it has these two things:

• Created UEFI Boot Options if hard drive already has UEFI

operating system installed.

 

• Fixed issue where operating system installation fails with UEFI.

I assume this might be related to our problem with not being able to boot Windows in UEFI mode and getting the error: "Reboot and select proper boot device or insert boot media in selected boot device and press a key".

If that is the case, maybe the same fix will be released for other boards?

@bman212121 thanks for testing. not fun to hear that you have so much issues, hopefully your new board will work better.
