Hey all, quick question I'm hoping someone can answer.TL:DR: I'm having issues with the VIA 4 (FOUR) USB 3.0 ports on my Z77x-UD3H board. They are extremely flakey and I'm seeking a permanent fix through either increased voltages to the right places or proper/better BIOS settings.
Is there anything at all I can do in the BIOS to increase power or something to the blasted bleeping VIA USB 3.0 ports, or is there perhaps some setting to make the VIA USB 3.0 ports behave properly?
My PC has been working stable for about a year since I built it. I have had these issues before, when initially setting the system up last year during about the first month or so of ownership but I alleviated the problem by moving all USB 2.0 devices to the USB 2.0 ports (which are on a 4 port header plugged addon bracket) and on the case.
I decided to get a USB 3.0 hub and external exclosure for a drive I had sitting down and now unless I plug things in an extremely specific way, the USB 3.0 ports below the PS/2 connection will drop completely. I basically have to leave 1 of the 4 VIA USB 3.0 ports on the back free or else I'll see dropouts. I just now received my Fractal Design R4 case (which means I'll now be utilizing the on board USB 3.0 internal header which I suspect is VIA, but I'm not sure) and I'm worried that whenever I use the USB 3.0 ports on the case it will cause system instability but it's one of the reasons I went ahead and decided to upgrade to a new case.
The devices I use on USB 3.0 so far (which have been safe):
2x Seagate Goflex Desktop drives (1GB and 2GB)
G15 plugged into it as well
To fix my current predicament, I use the Intel USB 3.0 ports for the hub now and plug the external into that. Not an elegant fix.
When I add the hub (Anker USB 3.0 4 port + 1 charging hub), it flips out the VIA ports and I see dropouts.
When I add 1 more hard drive to the VIA USB 3.0 ports, I see dropouts.
Any suggestions? Can I get someone with the board to maybe run some tests to see if theirs flips as well?
The board is a Gigabyte Z77x-UD3H v. 1.0. All I'd need someone to do is either plug a usb 3.0 hub and 2 usb drives into the VIA USB 3.0 ports on the back or arrive at some combination of 3 or better yet, 4 USB 3.0 devices on the VIA USB 3.0 ports on the back. The VIA ports if anyone is curious are the 4 that populate the board other than the 2 under the LAN port, which are Intel USB 3.0.
Help please! and Thanks.
