    Hi all :)

    happy to post here, it has been a long time i post a message here !

    Didn't know, but probably some people here have this problem too :

    Yesterday i need to transfer some data on Samsung SDXC UHS-1 64 Go, but it seems with Ricoh SD reader, some problems appear
    i'm on Win10 RS3 :

    1) I can heard the sound scheme about a peripheral connection.
    2) Explorer wait and you can see "the green bar" progression
    3) The icon ans the letter appear....
    4) No Way........ Can't work and explorer Hang :mad:

    Try to find the latest one , but same result, i precise mine was 6.10.1.5 before i decide to find a solution.

    i've found a package with number 2.15.17.02 (6.10.10.32 inside) here :

    https://www.touslesdrivers.com/index.php?v_page=23&v_code=32974

    There's a rep "Driver" who contain all the driver needed by the Ricoh SD card controller.
    Don't really matter if no mention about Win 10, it works.

    But Same result with my 64 GB SDXC, i observe only the name and version has changed by :

    Ricoh PCIe SDXC/MMC Host Controller
    25/05/2011
    6.10.10.32

    i search again and find this :

    www.catalog.update.microsoft.com/Search.aspx?q=Ricoh+SD+Host+Controller

    As you can see the latest seems to be the 6.10.1.5 :(

    But i see the 6.21.11.46..... try to DL it and try it.....
    Can't install it directly because WIn10 annoy me with Driver signature !!!

    To solve this, i take ONLY the Two .sys (risdxc64&x86) for Ricoh SDXC and MERGE IT into the 6.10.10.32
    But the 2 .sys version is 6.21.11.46, bigger than the 6.10.1.5 and 6.10.10.32

    Install it. ok..... no more drv signature Fu..k'in prob.....
    insert my SD..... YES IT WORKS :D

    Fully working with SDXC UHS card , my peek transfer is about 6.7 MB/s

    Ps: The .inf from 6.21.11.46 seems to be better, with more peripheral Inside,etc... but some investigation is necessary to resign and create a perfect driver.
    could probably install it with a modded .inf with F7 boot mode, but i do this to be more easier to install for newbie.

    I have the 7720 (non G) version and Mine supports 4 gb of ram. I think that was more of a windows thing and not a hardware thing. I have 4 gb in mine and it reads and uses 4gb. that is running windows 10. I think that 32bit windows vista (and maybe 7) was limited to 3gb of ram.

    Mine, 7720G with ICL50 motherboard Rev 3.0 (yes, i'm Lucky), support only 4GB, if i put 8GB Inside, no problem, the bios see it correctly (blackedition 1.45).
    In Windows, 8GB appears too, but only 4GB are usable.
    As far as i could remember, it's a bug from the chipset.

    PS : Forget to precise i use Win10 (1803) 64bit Os.
    ALL 32 bit OS limit for memory Adressing are 4GB MAX (2^32 = 4GB)

    I know mine uses all 4gb. Like I said, 32bit windows had a 3gb limit. I don't know about having 8gb of ram in MY system. I know all four a being used now.
