Hey everyone! I noticed the same issue in the forum. I thought XMP was trying to understand memory, but setting it to auto (the default) caused the same problem. I saw it cycle twice before reaching Windows login, which took about 38 seconds.
Are you starting from a brand-new Windows setup? Could be any version depending on your drive layout—MBR versus GPT might influence how quickly it boots. I didn’t see any mention of disabling RST or removing drives, so I can’t confirm that detail. It’s clear running RAID 0 will prevent the OS from loading, but this gives a solid baseline for testing. If you’re using an older MOBO with RST support, expect extra delays because it needs to load an optional ROM. You might see slower starts if your graphics card is outdated—consider adjusting PCI slots to match its original specifications for a smoother boot.
It's a brand new version of Windows 11 (the latest ISO available by end of January) in GPT format. I didn't just turn off RST, I disabled it along with removing all non-OS drives—two old SATA drives, plus the Samsung 980Pro boot drive. With only the boot drive active, performance improved noticeably by about 3 to 4 seconds. I'm planning to experiment further but my biggest concern is memory training and slow USB device detection when using a USB switch. The 2080Ti uses PCIe 3; I'll consider switching it if it helps. A resizable bar might help if supported, though it wasn't originally supported. Also, I saw a new BIOS for the MB—will update it, noting it mentions support for high-capacity DDR5 memory kits, but that's not very clear.
