Rampage V Extreme Slow Boot in UEFI mode! Please Help!

Hi guys,

Who faced the problem of slow boot in UEFI mode from the moment PC power on until the appearance of the Windows 10 x64 desktop on RVE?

The download ring under the ROG logo passes 4 turns while Windows 10 boots. It's very long for UEFI, which should be loaded in seconds!

The system i7-5960X 4400 MHz (44 x 100), Kingston HyperX KHX3000C15D4/8GX (32GB DDR4-2667), GeForce GTX TITAN (6GB), PCI Express x4 Sound Blaster ZxR + DBpro board, 5 HDD (including 2 SSD SATA- III, 3 HDD SATA-II, all disks GPT), USB connected: printer Samsung SCX-4600, keyboard and mouse. Water cooling system on the pump EK-D5.

OS installed as UEFI on SSD Samsung 850 Pro 1TB. BIOS version 3504, CSM is disabled.

Can there be a slowdown in UEFI boot due to SATA-II hard disks (non-SSD) connected or because the system is built on water cooling?

Clear your CMOS to bring your system back to defaults. See if it still takes that long.

Was XMP disabled? And are you using a single memory kit?

I'm surprised that the elite board like Rampage V Extreme has such a long boot time in UEFI!
I thought the main advantage of Uefi BIOS was the fast boot speed. And now I understand that the more expensive the motherboard, the slower the boot time! 😞
Will the booting accelerate if I replace SSD SATA-III Samsung 850 PRO with SSD M.2 Samsung 960 PRO?
If it is not difficult to give your examples of the rig boot time on the RVE, and specify the cooling water or air. Thanks!

I chose the Overclocking Preset - Gamers' OC Profile for 8 Core Hasweel-E CPU

Boot time comes down to a multitude of things. It's certainly not a logical way of measuring the performance of a particular motherboard. Only thing worth suggesting is to try with minimal devices connected to the system, but even then, that's not always practical.

Not really a valid concern.
