GA-X99-UD5 post reboot loop

[esgeroth]

I just started a new build with the following hardware: GA-X99-UD5, intel i7 5960X, Crucial 8GB DDR4 (CT8G4DFD8213), and an Evga Geforce 660.
When I power the system on it will show the gigabyte logo screen with the options to enter bios or boot menu at the bottom, then beeps once and powers off. It will not enter the bios from either hitting the delete key on the keyboard or by pushing the direct to bios button on the motherboard. There is no response from the keyboard. I have tried resetting the bios even though I have not been able to get in to make any changes.
What should I try next?

How many sticks of memory are you using. If just one it has to be in slot 3 not slot 1.  If two sticks they have to be in slots 3 & 7.

If that doesn't work than check to make sure you don't have a bent pin in the CPU socket.

I found my problem to be a usb card reader. I thought that I had alll the peripherals unplugged but the card reader was still plugged in. Without the card reader the system boots fine. Now the problem is I have tried 3 different card readers to the same effect. If there is a card reader plugged in then the system will reboot as soon as the gigabyte logo is displayed. Any idea why a card reader will cause the system to do this?

Are you on latest BIOS......F8b ?

I've had the same thing happen with my X-99 Gaming G1 WIFI.  It has been running fine for a day, then I started adding my external USB hard drives, some USB 3.0, some USB 2.0.  With the USB 3.0 drives connected it was still fine.  The USB 2.0 drives are connected to an external hub.  When I connected the hub is when the problem started.  Cleared the CMOS, pushed direct to bios, switched to bios 2 all to no effect. When I unplugged ALL the USB cables and the hub it finally booted to the bios and I had to reset everything as I had before.

Will the latest bios fix this abberant behavior?

I had the exact same thing happen on my X99 Gamer 5 board and an Asus X99 Deluxe board. With no USB plugs (other than keyboard and mouse) the boards booted fine. But once I plugged in a couple of hubs and other devices, the boards would not boot. This appears to be a X99 issue - not just limited to Gigabyte.

I had the same problem, posted about it here:  http://forum.giga-byte.co.uk/index.php/topic,15150.0.html

What makes you say it appears to be an x99 issue?  I guess other people with x99 boards are having the same USB issues?

Hi Zil Jay - The only reason I think it may be a problem inhernet to X99 Boards is that I hade the exact same issue with both my Asus X99 Deluxe Board (which I returned) and the Gigabyte X99 Gamer 5. Disabling USB during boot was a temporary fix for both boards.

I have a Ga-X99-UD4 and I have USB stuff plugged in. I'm not having any problem with the boot. It has the 1st bios that came with the board too F5.

I had the exact same problem with my gaming 5 board. It would show the logo, beep once, then a black screen for a while & then reboot. Q-flash plus to the latest bios fixed it. No ram, nothing plugged into usb, no GPU & with a fat32 flash drive with a renamed bios in the white port. Might do a few reboots before it takes.

Hi all, I have a GA-X99-UD5 Wifi rev 1.0 with a latest F8 bios (Dec/18/2014) running on Windows 7 x64 bit in UEFI mode. My card reader is AXAGO CRI-XS USB3.0. When I connect it I get a bootloop with "B4" code - USB device hot plug-in. When I plug it in running Os, it start work, but when I plug USB3.0 Flash drive to port on reader I get Windows Warning of not running on SuperSpeed.

I take a ticket on Gigabyte technical support:

Question:    Hi, I have a problem with USB3.0 Card Reader. If I connect it to internal connector Board will restart with B4 code. Reader is new. I tried flash bios F7 and F8 without succes. F8 will freeze right after I go into bios menu. Sometime after reboot from windows It freeze with GIGABITE logo and A2 code or in 61 code.    12/25/2014 3:41 PM

Dear Antonín Skala,

Because Intel had confirmed there will be frequency interference issue with USB 3.0 and 2.4GHz devices. Kindly confirm whether you use any wireless USB keyboard / mouse? If so, please remove it and test again. If the problem remains, we suggest you to connect the card reader after the computer boots into Windows successfully and see if it can work well.

Regards,
GIGABYTE

I don't use a wireless device so it isn'n a problem.

Is there anybody with this board and Windows 8/8.1?

I had a problem with the Logitech Unifying receiver for my wireless trackball and keyboard. Logitech provided a free extension wire to move the receiver away from the USB 3.0 ports and now I don't have any of the jittery problems anymore.

Funny how Gigabyte is placing the blame on USB 3.0 wireless interference problems for the card reader problem.

Just a recent update,
I have the boot loop issue when I have a 2TB usb 3 HDD plugged in. I am using a x99 gaming 5 board.  But what is worse is that I can also no longer open up bios, it just sits with a black screen.  If I remove my keyboard it will show a B4 in the bottom corner of screen. If I do want to enter the bios I have to flash the bios in windows to the same version (F7) and once rebooted it will allow me into the bios, but only once.  It's a complete pain.  Also I have absolutely no 2.4 GHz devices plugged in.
