Hi all,

Just wondering if anyone has tried USB3 on one of the Asus motherboards? They all seem to use the same chipsets being an NEC Renesas 7000 series but mine isn't playing ball.

USB3 is enabled in the BIOS and showing up in device manager. I have installed the NEC drivers from the ASUS website and also tried some newer ones. I have also tried updating the firmware to the latest version.

If I connect up my USB3 external HDD (I have 3, Verbatim, WD and a Samsung F4 in a USB3 enclosure) with the drivers installed I get nothing. No drive in storage manager, my computer, device manager, NOTHING.

If I remove the driver, or even just disable it in device manager the drive immediatley comes alive albeit at USB2 speeds.

HDD is always plugged into the blue USB3 port using a blue USB3 cable (tried three different USB3 cables). I have no issues using the USB2 ports though.

This is very weird!!

It's not the USB3 drives as I can't believe all three would have problems. Looks like something to do with the motherboard.

I have even tried installing Service Pack 1 RTM as I heard that has some USB3 upgrades but still have the problem.

any ideas?

Thanks!!

Just to update this thread incase anyone has this issue in the future.... (im good like that)

I believe the issue is caused by running the PCI-E frequency over 100MHz. I shall have a look at my bios tonight and report back.
 
USB3 limited to USB2 Speed on Asus MB

Confirmed, the PCI-E frequency does indeed need to be at 100MHz

Mine was 105MHz, dropped it down and hey presto full USB3 speeds :D


I had the same problem on my Asus MB running i7 at 3.8Ghz 8GB Ram. Tried loading latest drivers and flashing bios, all to no avail. The USB3 ports on MB were limited to USB2 throughput.

Thanks to the above post from Glen8, I changed PCI-E clock from 105MHz to 100MHz and 'hey presto' it worked for me too :D

Thanks to Google, Overclockers.co.uk and of course Glen!

Spread the word!
