asrock extreme 4 gen 3, slow usb 3 speed on front panel.

[madmax2]

Hi

I bought the asrock extreme 4 gen 3

I noticed when I test the speed of the usb 3 using the included front header usb 3 panel
the speed is really slow

but the backpanel usb 3 runs at usb 3 speed when tested.

All usb 3 drivers are installed.

I used crystal diskmark x64

front usb3 header (the front usb3 bracket is included with the motherboard)

Anyone get the same problem?

Both test were done 2 times and the same results occured..

Not sure what you're upset about, you're blowing me away with those speeds. I'm getting transfer speed starting at about 20mb/s dropping to about 6mb/s after about ten seconds for both my front and back panels.

Can i assume you're running driver version 1.0.0.96?

I have exactly same problem with my USB 3.0 front ports.

My back USB 3.0 ports works like a charm, but when I switch to the front ports it seems like my portable disk is working in USB 2.0 mode:



My external HDD has got LED. It becomes Blue when USB 3.0 mode is active (back ports), and Green when USB 2.0 mode is on (front ports). It's not simply performance issue. I would call it fake USB 3.0.

Latest Etron drivers, fresh OS installation.

radier, Interesting results. Please elaborate on "fake usb 3.0".

I see we both have the crucial m4 - Did you update your diver to 0009. Heard it increases speed by at least 20%.

Is your usb 3.0 header stock from your case?

Updated the driver to 1.0.0.104 as well as tried a beta driver I found on their website. No change.

Fresh install would be delightful (done one already), and will only do it if I'm about to return my board...

As I describe it. My External HDD has got Status LED. It becomes blue when USB 3.0 mode is active (when I connect it to back USB 3.0 ports) and it is green when running in USB 2.0 port. In my case it should be blue when I put it to front Panel USB 3.0 but it isn't. The performance difference is HUGE.

About other questions:
My Crucial is already on 009.
I am using front USB 3.0 Panel from ASRock.
I have tested all drivers from .101 to 105 before and after fresh OS installation.

I've got exactly the same speeds for rear and front usb 3.0 and exactly 1/2 the speed running the same drive on win XP 32bit computer.

Your situation would tell me it's hardware issue. But for me, my guess is it may be windows 7 related. A clean instal may be coming...

[radier]

How many clean installation it need to start working as it should? 10 or maybe 20? That ain't kind of answer I need.
