I'm suffering from a lot of random restarts. I will check out the memory profile settings and see if that fixes things. I have kept up to date with updates and even tried the beta BIOS updates.
Probably bad info from a misinformed tech rep. My board purchased on launch day is C1 and I'm sure most others from the last 2 months are as well. As others have stated, the message about C2 has been consistent, they should only be hitting the market around now.
Personally this errata hasn't impacted me, my connected USB bays/enclosures are both detected after waking from S3 Sleep, one is USB 3.0 one is not.
I had a bumpy run at the start with this board and chipset to start as well, nothing game breaking but certainly very annoying. Here's a few things you can try that I figured out as I went:
1) Update your BIOS. F5 was the first stable release for many, for that board and most others in the UD line it looks like Gigabyte has settled on F6 as the latest stable BIOS.
2) Don't use XMP profiles. Will result in all kinds of flakiness and instability, from corrupted audio to random restarts and bluescreens (blaming Nvidia drivers, no less). This was actually pretty crippling until I figured it out.
3) Adjust Intel NIC settings in Device Manager to fix wake from sleep issues. If your computer went to Sleep and woke right back up, it's the WoL settings in the Device Manager properties for the NIC. Toggle off the WoL settings and you should be good to go.
4) ALWAYS make sure to set the SATA controller to RAID after BIOS flash or porting drives from an old build if you are using any RAID0 arrays. Unlike previous Intel chipsets, Z87 RAID controller does allow you to boot to an OS install set to RAID, even when the controller is set to legacy or AHCI. In the past this would usually BSOD and fail to boot. As a result, your RAID disks will almost guaranteed lose the RAID metadata and be corrupted if you boot to Windows in AHCI mode. Even using various tools to recover the RAID metadata like testdisk did not work, even though I had success with them in the past.
Rig is running like a dream now for the most part, I dialed my OC back a bit to 4.2 so I don't need as much voltage, just tweaking performance on my RAID 0 arrays at this point.

1.Support Intel C2-stepping chipset
2.Improve PCIE-E compatibility
(Note) The USB driver must be updated in advanced.
Can you provide us with some links confirming what you say ?
I really thought C2 chipset was to adress the a USB3 S3 sleep bug!
thanks
He's one of Gigabyte's mobo gurus, he probably helped validate the new C2 chips as they came in.
I'd also like more info, if future MS hotfixes would fix the S3 bug on C1 too or only C2?
The $64,000 question is whether the mobo makers will eventually offer an exchange for C1 mobo, or perhaps a resolder of SB, or will they just leave everything as is. I guess I will have to call Intel one of these days to find out. No one else seems to know.
I bought the Gigabyte Z87X-UD5H board about a week ago and it has the revision C1.
I think this bug is trivial, it is however nice to know about it so that I don't go off on a wild goose chase trying to hunt down a USB problem, if I ever experience one.

Hello,
The only way to see if it is C2 stepping is via a sticker or label on the box. It can be either one of the attached examples.
Manufacturers will first finish selling their stock with C1 stepping chipset before switching to C2. It can be different for every model.
Best regards,
