We can use the Ultra Fast boot setting ONLY if several things are ALL TRUE about our PC and Windows installation: You must be using Windows 8, 8.1, or 10. You must have installed Windows for UEFI booting. That means you installed Windows with the CSM option set to Disabled. You must keep the CSM option disabled at all times. Your Windows drive will be formatted in GPT format, not MBR. The Windows installation will use the EFI boot loader, not the Legacy boot loader. The Windows installation media shown in the boot order must have this format: "UEFI: <device name>". If you did not select that entry in the boot order, you will not have a UEFI booting Windows installation. Your video source (graphics card or iGPU) must the GOP compatible. GOP is a UEFI video protocol that MUST be supported by the VBIOS of your video card. All EVGA video cards since the Nvidia 700 series are GOP compatible when you buy them. For other video card manufactures, I don't know, you must check with the manufacture. The Intel iGPU has had a GOP compatible VBIOS for many years. |
I've been using UEFI boot since Windows 8 and I'm sure I've done all the steps you mentioned. I even contacted Palit support to ask if my GPU is UEFI GOP compatible and they replied it is and even sent me the newest BIOS for my GPU. Actually I've been using this grapics card in my old computer with fast boot enabled with no problems so I was pretty sure it was OK, but just wanted to be 100% positive.
As I posted before I was playing all day yesterday with different settings, removing RAM sticks, trying to boot with only one stick and finally I ran Memtest86 for four hours without any errors so my conclusion was that RAM is OK. I detached all drives and GPU, connected my old SSD with Win10 installed in GPT to exclude faulty NVME drive (Samsung SM961) and everything went fine.
| But you are also telling me, that setting that port to enabled, you can use the Ultra Fast boot option? |
Yes, that is exactly what I'm saying :) When I was playing around with different configurations I always cleared CMOS before changing anything. My mistake was that the first thing I did in UEFI was disabling Serial Port and Parallel Port under Super IO Configuration. That is what I always do because I don't use them and I couldn't even imagine this setting could do such mess. After many hours of failures I decided to reboot every time I change one setting. I changed fans to silent, OC RAM, set CSM all to UEFI only and turn Ultra Fast boot on - all went perfect. Than I started to change other settings like Super IO configuration and that was it! When Parallel Port was disabled I couldn't boot, just saw ASRock logo and those small dots when windows is loading, after two seconds those dots stopped and I could only reset my computer.
| Just to check and be absolutely clear, you are talking about the Parallel Port setting in the Super IO Configuration screen, correct? |
Yes that is correct: the setting I am talking about is in the Super IO Configuration screen. I don't use any printer so I disabled it.
| You said when the Parallel Port option is set to Disabled, you won't get any sensor readings in HWiNFO or other programs, and CPU-Z will not show you any information about your CPU, correct? |
When that setting is disabled all programs show CPU info (CPU name etc.), CPU temperature but nothing else (no fan RPM, no voltages, no motherboard temperature). CPU-Z shows info about my CPU but no information about LPCIO [Nuvoton] [NCT6683] <- those fields are empty and LPCIO is grayed out when Parallel port is disabled. I hope this clarify what I was saying.
