Renesis USB3 is flaky on DX79SI, adding USB3 can be tricky

After fully checking out everything the DX79SI can do, it all works except for the Renesis USB3 capability.  The hubs and ports randomly come and go, and are essentially unusable.  None of them are reliable, not the on-board header nor the external ports.  So how hard can it be to purchase a PCI card to add robust USB3 ports to the system?  Harder than you'd think.  What you discover is that some of those cards ALSO have Renesis chipsets on them and won't work either.  The trick is to ensure you aren't buying an add-in card that uses NEC/Renesis chipsets.

 

I needed internal USB3 ports for some front-panel accessories, so chose and installed a well liked Koutech card.  Once I installed it I saw it had a Renesis chip and it used the same driver as the motherboard does.  The hubs and ports on the Koutech card didn't work at all.  It was hopeless.  Back to the store.

 

At least some of the SIIG USB3 PCI cards use a TI chipset (fortunately) and work fine.  I installed a JU-P40212-SI card and had zero problems.  Devices attached to it run as fast as the mobo USB3 ports run on those days they show up.  I loaded up all 4 ports on the SIIG card with USB3 devices and had no issues.

 

Clearly there are issues with the Renesis USB3 chipset and this mobo.  Given that reviews of the Koutech cards are good I have to assume the problem isn't all NEC/Renesis.  Fortunately other vendor chipsets can work to provide USB3 on this system, albeit they use up the limited number of PCI slots on this mobo.  Perhaps someday the problem is resolved.

 

Intel, I'm registering this as another incidence of USB3 issues on this mobo.  I'd be happy to share info.  I'm using 3930 processor & a RAID config.

    I found similar problems to that. I use a DX79SI/3930K under W7/64bit. Some problems

    are gone with the latest Bios update ( vers 430)  but the driver for the Renesas USB3 ports

    is unusable leaving the ports useless. The driver causes W7 hang on boot or causes BSODs

    on shutdown. I tried several suggestions mentioned here in the community but nothing

    worked longer then 10 minutes.

     

    INTEL: please debug those silly Renesas USB3 drivers!

     

    Another point is, that the BIOS on startup takes about 30-40 seconds to go over the "5A" state.

    I use an additonal Intel RS2BL080 Raid Controller, but the bios is so slow on startup.

     

    Hoping for better drivers.

    Same issue with USB 3 ports.  I just bought D-link 1310 USB 3 card and installed drivers.  Card worked like a charm and my external drive worked flawlessly.  I then tried the MB USB 3 ports again and now it is working fine.   There is obviously something wrong with drivers supplied by Intel.

     

    You can try D-Link drivers for this card even without the card. Still Renesis but they work.  External back up still going after 42 minutes where it used to loose connection after about 10 minutes.

    Good find, though only supports the front ports? and still causes exceedingly long boot time [near 2 mins] on the DX79SR board.

    Well, there is hope yet! After installing all ms updates - important and recommended ex. lang packs, the boot time has reduced from a 'go make a coffee' 2 mins to a not too shabby 42 secs!!

    Happiness may be just a mouse click away yet!
