Gawd, if anyone has tips I'm open to them. I am running Windows 10 Pro, full UEFI bios, ultra fast boot, installed as UEFI from a USB stick directly to the 950 Pro and it's plugged into the M2 slot. I initially installed the Samsung NVME drivers after Windows booted for the first time. I've disabled CSM to test, re-enabled it - still slow to boot. From what I've read I'm not the only one. M.2 disks are super slow to boot. But, like I said, if there are any suggestions I'll take them.
Edit: Windows boots in about 8 seconds. The bios ads around 20 seconds from the time I hit the power to seeing the Windows logo. I also have 32GB of memory, so maybe that adds time to the bios? However, I think Ultra Fast boot skips the memory verification, if I'm not mistaken. But, with my old 840 Pro on the same bios version I was logged into windows within around 12 seconds flat from hitting the power button. So it ain't the mobo or bios. It's the 950 itself. At least that's what I've surmised.
sounds more like BIOS is taking it's time detecting the NVMe drive for some reason.on my Z97 board I have fast boot enabled, boot device only, and in windows i have hibernation off (which turns off win10's fast boot feature which uses part of the hibernation file to load up a tad faster). I dunno, maybe some of the above is why I don't experience the issues or because Z97 and Z170 have built-in M.2 support in the chipset. X99 doesn't afaik, but bios' were updated to detect and boot NVMe's
Edit: could try updating your BIOS, but if it's an Asus board and they released a newer motherboard version then you're probably SoL since they have a bad habbit of not supporting/updating previous models well.
Edit2: also, regarding the occasional slow boots I experience - I see the windows logo but it doesn't move for about 30-60 seconds, however I see HDD led activity like windows is verifying all boot files (happens sometimes when I update drivers or change some service startup and such). otherwise i normally boot from bios to desktop in like 10 seconds
P.S. Still waiting on Samsung's promised firmware update... sigh.Edited by s74r1 - 7/1/16 at 7:47pm
