    Clarification of PCIE standards and backward compatibilty


    I am tearing my hair out with a problem I have getting an eSATA card working in a Dell Optiplex 3040 system. The PCIE card is a Startech PEXESATA1 eSATA card which came with one of their 3.5" 4 bay enclosures. It has worked fine on various Acer/Asus and Gigabyte motherboards under windows XP but will not install in the Dell Optiplex 3040!! I have tried disabling Secureboot, I have enabled Legacy ROM in the UEFI bios but the card is still not recognised. The system has a 6th Generation i5 and Intel® H110 Chipset.
    A reply to another post about an eSATA card on a Dell Optiplex 3020 says that the card will not be recognised with Secureboot enabled under Windows 8 so I assumed the same applied to Windows 10??
    There was also some discussion about compatibility between PCIE v1.0 card and PCIE v3.0 slots on later motherboards and that the system could not "down clock" for older boards. However everything I can find on PCIE standards leads me to think it is backwards compatible.
    Is that correct or do I need a later card. If so how do I know that the card is PCIE v3.0 comptible. Most specs just say PCIE x1 referring to the bus speed.
    I thought I was well read but this has me beat

    With that card being End of Life, it may be time to get a newer card that is SATA III compatible.

    Hi.

    Have you tried contacting Startech?
    Their technical support is very good, IMO.

    Worth a shot... for a legacy product.

    Thanks Bro67,
    The card is only to connect to the StarTech enclosure which is also of same era and SATA II so there would be no speed advantage getting a SATA III card. However I agree that It needs to be compatible with the new OS so thats probably the route to take. I am just trying to get my head around the PCIE standards and whether a version 1.0 card will work in a version 3.0 slot.

    Thanks Compumind,
    I did contact Startech but didnt have a response or thought that ws the case until I found their email in my spam yesterday. They agree that their PCIE 1.0 card SHOULD be recognised and work in PCIE v3.0 slot but as the card has not been tested with windows 10 they advise purchasing a card that has been tested. As Bro67 has suggested above the card is now legacy and for compatibility I would be better getting a new card. My only concern is that the new card wont be recognised in the Optiplex bios because it an issue with the Dell system rather than a compatibility mismatch. Unfortunately I have not had any response from the Dell forum and as the system is now out of warranty there is no Dell technical support without payment!!
    Thanks for your reply

    Hi.

    Take a look here:

    Make sure that your system is up-to-date, including the BIOS.
    Go to Drivers and Downloads -> sort by Release Date (most recent on top.)

    I think that there is a new BIOS, among other things.
    You might have to get a new card, since eSATA is very old.

    Best of luck to you.
