    Same results with only the microcode patch as well? Or have Dell screwed up the performance even more than needed?

    i don't know, did not test because if it does update the microcode, there may not be a way to downgrade.....so no experiment for me. Also my Alienware 18 is long dead and parted out.....junk computer.

    I already upgraded stock bios a12 to a13 on aw18/4930mx during installing new system with drivers from dell website, cause I wasn't aware of such meltdown/spectre possible performance loss... poor fool, why it happened while everything worked well on a12 :)
    Why dellsh*t doesn't inform on his bios download page that it can be perf losses after flashing? It's a liitle bit cheating from their side.
    But let's hope perf loss won't be so visible if it really occurs... but it's not my main problem... I'd like to change my 980ms sli to 1070m and read that it is necessary to change to SG mode... afik it's impossible in aw18 stock bios (I didn't have time to check a13 settings thoroughly but suppose that).
    So if it wouldn't be chance to downgrade to a12 which can be 100% unblocked, I will be probably the first person in the world who asks sb like pythonic to unblock bios a13... anyone knows if it can be unblocked easily like a12?

    The huge performance loss for older than Skylake chips with meltdown/spectre fix is well documented on the web.

    Hi All, just a heads up; You can always roll back from the A13 bios to the A12 bios by simply running the A12 bios installer. I had noticed my AW18 was noticeably slower after updating to the A13 bios, so I ran the A12 installer and it rolled back fine. PC is now performing as per norm.

    I updated an AW18 from A12 to A13 and Cinebench stayed the same (~800) @ 4Ghz, but that wasn't the unlocked variant. When I come across another AW18 build out, Ill give the unlocked version a run if it allows undervolting via BIOS since C states set really sets it up for a sweet, sweet OSX86 box.

    I don’t remember if I patched the package c state lock in this bios but I can do it later, so that you stop having to patch the kernel and appleintelcpupoweanagement.kext
