    Question Maximus V Formula EFI compatibility errors

    Every time I try disabling CSM for faster boot times I get the error that my VGA card is incompatible, Its an old Radeon HD 6850. in doing research ive found out that its because Im using a HDMI cable to my Samsung TV. apparently there is no work around for this. No big deal ive planned on changing it out anyways, but when i remove the graphics card and use the iGPU, It still wont let me disable CSM. It'll go through post, show the windows flag, and during that hand off it restarts back to post. Any Ideas??

    specs:
    MVF mobo (1408 bios version)
    i7-2700k
    CM 212 Evo cooler
    G. Skill Trident X 2400 (down clocked to 2133 thankyou sandybridge)
    kingston HyperX 120gb SSD
    Pioneer Blue-ray burner
    Corsiar HX750 PSU
    ATI Radeon HD 6850

    The SSD is partitioned in the GPT format, all drivers are fully up to date, and im running Win 7

    I've already tried disconnecting every component except the SSD, disabled legacy usb support, disabled all hardware LAN, WIFI, BT, Asmedia controllers, ect.

    Csm compatibility support mode, its under the boot tab in my bios, directly above secure boot. Its my understanding that its used to boot non efi OS' from the various Ports that are capable of booting from. LAN, storage, pci.

    im getting ready to do the same thing (trying to figure out how to reformat windows 8 in gpt right now) anyways I found out that even with my new GeForce 660ti 3gb the bios wasnt uefi so i had to request new bios update from EVGA, 2 days later I recieved the email with uefi bios. flashed it no problem. Hopefully i wil be good to go after refomat.
    I read somewhere that without uefi bios on graphics card. you must set to PCIe legacy oprom first in bios boot settings or something like that.
    I hope this helps!

    (this is my first post ever in any forum)

    Im sorry I may not have understood exactly what your trying to do. I believe disabling CSM is used when one wants to use secure boot in windows 8.

    im trying to make my system run as full efi to speed up my boot times. I feel that they are WAY to slow given the hardware installed, and how quickly very similar systems boot.

    mine takes about 13 sec. from the time I press the power button till POST finishes, 7ish seconds showing part of the windows flag, and another 3-4 @ the windows loading circle.

    Ive benched my SSD @ 525MB/s write and 555MB/s read so thats not the issue.

    now another system using the p8z77-v deluxe mobo, i7-3770k, corsiar dominator 2133 ram, ocz agility 4 ssd (which benches slower than mine) has a total boot time from button pushed to homescreen of 4 sec. I do have fastboot enabled, all my extras turned off in the bios, but nothing gives. I've tried searching around for typical MVF POST times are but i haven't had any luck. If i could get some answers if my POST time is normal, if the iGPU on the 2700k is not EFI compatible...

    I wouldn't be nitpicking a second here or there but a 20 second difference? when all my hardware (except cpu) is better than his, it just doesn't add up

    Sounds to me like dude is running windows 8. your boot times seem typical to me if you are on 7. I have never used a 2700k dont know much about it. I would check your startup and see how many programs are set to automatically start with windows.

    by the way hows that trident x with the MVF been treating you?? I think I might buy 16gb right now
