    Anybody try this yet?

    Driver Details | Dell US

    Fixes & EnhancementsFixes
    -Not Applicable
    Enhancements
    -Enhanced SMBIOS TYPE01 Offset 19h to Product name.
    -Enhanced update DIMM isolation protocol.
    -Enhanced update ePSA to 4220A10.(4220.11)

    Does not seem like much for the update but DIMM isolation protocol? Would this just assist in determining which RAM stick is bad instead of troubleshooting for each one?

    since their seem to be no issues that it "fixes" I think I will avoid it. Enhancements don't seem to affect me at all either.

    UEFI is fine, I run it, you might need the newer vBIOS though, the older ones (I can see your vbios will more likely be not UEFI compatible as your processor is the slightly older one). The vBIOS must be UEFI compatible otherwise it won't boot since the card will fail to initialize. My laptop will not POST/load windows with only dedicated GPU, since my vBIOS is slightly older, but I hardly ever use it on dGPU mode optimus is fine for me.

    Might be worth checking on techinferno for any later vBIOS for your 660m, that should make it UEFI compatible. I doubt any BIOS updates will fix it.

    I would not update it unless I'm having an issue. If it's not broken, don't fix it. This BIOS does not have many changes anyway.
