P55A-UD4 rev.1 - USB 3.0 randomly disconnects

post #1 of 10
Thread Starter 
Hi OCN,

The other day i bought a ASUS AN300 EXT. HDD. It's 500GB and is usb 3.0 capable. When i plug it into my computer it accesses it for say, 30mins, then disconnects. I unplug it and then replug it and it still wont show on my computer screen but it shows on the "safely remove hardware" menu when i right click it - on some/most occasions. Its only when i plug it into the other usb 3.0 port it detects(note i have two usb 3.0 ports). I have downloaded the latest driver from the website and it still occurs. I tried using the driver that came with my mobo and it still occurs. Ive tried NEC Electronics USB 3.0 Host Controller driver version 1.0.14.0 and the Renesas one that GB official website lists. Is my usb 3.0 socket dead?

edit: i just realised both sockets do disconnect randomly. it also happens most after i restart with the disk plugged in.

Thanks.

I have almost the same board as you (UD4P) with the same USB 3.0 controller. Are you sure it isn't the hard drive? I have a Seagate external 3.0 that is very finicky. If the cable isn't positioned just so, it will fail to connect. Most likely due to a faulty USB3/SATA interface on the HDD.

Test another USB 3 device if you can, and if that also randomly disconnects, then yeah most likely your 3.0 ports are hosed.

Also, if you haven't already, make sure your BIOS is up to date and try changing the USB 3.0 mode in BIOS. XHCI is "full" USB 3.0, but if that doesn't work try changing to EHCI and see if there is an improvement.

hi thanks for the reply,

i'll try the BIOS thing but only versions up to F9 work for rev 1.0. The others only work for 2.0, ive tried. i dont think its my hard disk coz it works on usb 2.0 ports.

also how much voltage vtt/vcore do you need for 3.8ghz?

My vcore is 1.3625 and vtt is 1.33. I think they are a bit high compared to similar overclocks with the 860 but I have HT on, LLC off, and all 4 banks of memory populated.

yeh its a bit high, i cant believe some people get 4.0ghz under 1.3v with HT on. mines on 1.3v 3.8ghz with HT on.

back to the subject, about my USB 3.0, it just happens to one port only, i dont think its a driver issue then is it?

Yeah I don't think I won the CPU lottery with my 860. It took a ton of experimentation and this is the lowest combo of vcore/vtt @ 3.8 that passes both LinX and Prime95 testing.

If it's just one USB port that is acting up, then you are probably right, sounds like a defective port.

bl about the cpu, what temps you getting? i get 45 idle and 87 load.

damn i thought my mobo was good, i had it for about a year now it starts acting up freakinnggggg.......i might just RMA but i need my comp though and dont have a spare 1156 lying around...

Your temps seem kinda high. I'm getting 28 idle (probably not accurate) and 66 load. Thats with Megahalems and 2 Scythe GT1850s in push/pull.

Yeah RMAing a mobo is a pain. If you can do it though, you'll probably get a rev2 board in return!

the temps dont really matter i guess, the cpu these days can run 90 deg for months and still not die, ive read from other articles...

yeh i might get a 2.0 if im lucky, because gigabyte dont manufacture rev 1.0 anymore do they?

Most folks in the Intel CPU forum recommend keeping your temps under 75/load for long term use...

I've never RMAd a board with Gigabyte so I can't be sure. Maybe ask in the Tweaktown Gigabyte forum? There is a mod there that is a Gigabyte rep.
