X99m Gaming 5 general USB issues

<< < (2/2)

More on this. By switching all my USB stuff to the back ports (USB2 and 3) I seem to be able to avoid problems with USB disks disconnecting every few minutes. I've tried tinkering with the chipset routing but that seems to make no difference.

The length of time it takes to boot the system from cold varies depending on precisely what's plugged in where. If I move my mouse (!) from a USB2 port to a USB3 port, it saves around 10 seconds of in-BIOS boot time. That's giving me a 20 second boot instead of 30 seconds. With an M2 SSD I'm not impressed, but I suppose I don't care much as I don't do a lot of rebooting.

Guys, your BIOS isn't great if it's waiting 10 seconds to work out that my mouse is in fact a mouse. Jeez.

On that, Windows 8.1 kernel snapshot "fast startup" doesn't work on these boards. The problem I think is that although it'll load the image from the M2 SSD, the other disks apparently aren't ready at that point, irrespective of how I tweak the BIOS... the result is that it shuts down with a list of drives (in my case right now one other SSD and one lage SATA disk, all MBR), and then when it starts up... one of those disks is not visible to it there in the BIOS, so it fails the fast startup. The result is that "fast startup" is in fact slow startup. Sure, I can disable it in Windows, but this board is supposed to support Windows.

And just when you thought it couldn't get any worse...
 - with the F2 BIOS I could achieve XMP1 with my DDR4 memory and a reasonable overclock on the CPU.
 - the F3 BIOS won't boot with either memory or CPU in those same settings.

What did you do to F3 that you're not telling us? It's sort of vaguely useful if you were to provide a list of changes with these things.

I'm sure your company won't die if I RMA this thing, but a bit of support would vaguely be useful. We buy this stuff with some knowledge it's not perfect, but if you want us to help us fix your broken stuff, then some information would be useful.

I had 5 Saitek Panels turning off that I had connected through a external hub to a front USB3 port.

Then I found a setting in Windows for the internal hubs under Device Manager/USB Root Hubs/Properties/Power Management > Allow the computer to turn off this device to save power.

After I de-selected it, the Saitek Panels didn't turn off anymore.

Curious if yours is selected on the front port only causing your USB disks to disconnect.

USB Issues
Thanks, no I tried that when the problem first came up. I think that was a Windows 8.0 issue (from my original googling), but it made no difference to my issue. I poked about a lot in the Windows logs too and found no evidence of power save stuff in there. Worth a try though.

My latest experiment is to turn off all the legacy stuff in the BIOS. FFS this is the bleeding edge board and I don't have any old **** attached to it, so why would I need that? So I disabled it all, and also turned off all the "route this to that" nonsense for USB. The idea is that I need none of that stuff to boot, so maybe it'll reduce the time if I get rid of it. It seems to do so.

The yellow USB 2.0 ports on the back no longer work, presumably because I'm not "routing" them anywhere good. However why would I want to use those... USB3 is backwards compatible and I'm not short of ports.

Windows 8.1 fast start still fails reliably, but I assume that's because the other disks I have aren't available at UEFI boot time. That needs to remain off.


Overclocking is impossible with F3 - it just won't play at all. I'll need to google around for that I guess.

philw:
I reverted to F2 and that overclocks just fine.

Gigabyte: the F3 BIOS does not seem to be overclockable.

Maggpies:
I think I have found a solution for the USB issues. I have been having a lot of disconnects with my USB devices with Win 7 Pro and i have got them to stop. the BIOS version i am using is F3. Go in to BIOS Under peripherals set EHCI hand-off to enabled. Then under chipset set the XHCI mode to enabled not smart auto its not so smart. I hope this helps some of you out. :)
