    slow device speed in W10 Pro


    Hi, brand new SSD (500G) installed with clean install of W10Pro. After installing AMD Radeon HD 8570 D Catalyst Control device driver for my second monitor my internet device speed went down from 872/790 (D/U) to 400/480. After further installing Kaspersky Total Security my speed dropped to 150/175.
    what is going on? Got a 1Gbps fiber optic connection (BELL, CA), 8G RAM and my CPU is only around 44% used.
    cheers Istvan

    Slow Read Speeds with new SSD In Mac Pro

    Enabling AHCI (http://www.bladedmink.com/windows-8-ahci-support-on-macbook-pro/) upped the average speed from 180MB/Sec to 225MB/Sec.

    Note the following steps are actually for a Macbook Pro (laptop), but worked a charm on my Mac Pro (desktop).

    Edit:

    Crucial steps from bladedmink.com incase it ever disappears - Note, read through all these steps before actually performing them.

    • Login to Windows
    • Launch Regedit
    • Find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\
      • Edit the ErrorControl Data value from 3 to 0.
    • Find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride\
      • Edit the 0 Data value from 3 to 0.
    • Shutdown and boot into OS X
    • Download and run https://www.bladedmink.com/wp-content/uploads/2014/06/AHCI_Enabler.zip on the NTFS drive.
    • Shutdown and boot into Windows
    • Prey you don't get a BSOD.

    I am using the Standard Microsoft AHCI controller driver.

    I tried to to install the Intel Matrix AHCI drivers, but they actually ran a few percent slower. When I tried to uninstall (and checked the 'also delete drivers') from Device Manager I got a boot loop and had to install windows from scratch.

    Slow Download Speed

    Hi,

    Thank you for posting your query in Microsoft forums.

    • I would suggest you to test the speed using any of the speed test website or app to confirm the upload and download speed.
    • I also suggest you to reset the wireless router to check if that helps.
    • You may plug in the Ethernet cable if available and check the speed.


    Hope the information is helpful. Feel free to write to us for any other assistance with Windows, we’ll be glad to assist you
