USB 3.0 Question

[direelite1134]

Hey,

 

I recently got a usb 3.0 harddrive because my video card was crashing(53 times yesterday) to make a back up in case I had to send my computer to the manufacturer. I had been using a 2.0 hard drive and was getting speeds of about 15mbps. Then I switched to the 3.0 and got about 18mbps. So I got on the internet and think I got the right Drivers (for a Asus G73sw-A1 if anyone knows of better drivers?) and Saw 70mbps right away but then it eventually dwindled to 8mbps. half as fast as my usb 2.0? So something has to be wrong? I mean when I start copying I get around 60-50mbps, but it always goes down between 10-20. I have read up and it seems i should atleast see around 70-100. Would any of you guys be able to tell me potentially what could be wrong?

 

I'm running Windows 7 64 bit

Got a Asus G73sw-A1

And a Seagate 1tb 3.0 external drive.

And this is the driver I installed: USB3_Fresco_Win7_64_Z35240 which I found on the Asus forums.

 

As for the graphics card Issue, it seems to be fixed for now, but it had no reason to start in the first place so who knows

Thanks for any help!

Thanks for the response.

 

I had thought I had already had the selected but when I plugged it in again it wasn't. Anyways in trying it out. . . it did seem to help for a minute or two then it still tapers down to sub 2.0 transfer rates. like 20mbps.

what is your external drive speed superspeed or high speed?

to find out , this time go to Universal Serial Bus controller(last in Device Manager) ->Usb root hub->properties

now find your drive in power tab...if not found try another hub

if found go to "Advanced" tab and see the status about Hub (is operating at full/High/Super speed)

[direelite1134]

I looked at all 3 of the hubs I found, the ones I believe to be my 2.0 ports all had the tab and said high speed.

Unfortunately the one I think is my 3.0 (its called Fresco Logic xHCI (USB3) Root hub) does not seem to have the advanced tab. So there is no telling if what its speed is.

The box of the harddrive states is a super speed USB3 capable harddrive though. If my computer would recognize it.

 

While i was there I did have windows look for a driver update but there was none found.

first download and install this one

Intel HM65 driver

 

 

then this one

Fresco 4-12-2012/3.5.46.0

 

Make a Backup! hope its fix the problem because the above drivers are kinda prototype :dry:
