Current BIOS: 3401
Tested BIOS versions: 2202, 3401 and 3504
CPU: Intel Core i7-6700K 4 GHz LGA1151 with Noctua NH-D15
Memory: Corsair Vengeance LPX DDR4 3200 MHz 64 Gb ( CMK64GX4M4B3200C16 ) ( not in QVL )
I have a cold boot problem when XMP profile is enabled.
When I enable XMP profile for this memory kit, the memory runs flawlessly @ 3200MHz for days and months, with and without stress.
System is fully operational after restarting and so on, but when I shut down from Windows 10 x64 and then start again it won't POST ( q code 00 or 55(ram not installed) ) and only way to start the engines is to reset CMOS first for default memory values @ 2133MHz. During this code, the rear chassis fan isn't spinning, but CPU fans were. No signal on monitor.
Once I manage to start the system, the memory runs
@3200MHz for a month straight, as long as I don't shut it down from Windows. So, the voltages seem to be where they should. System is rock stable.
I noticed that if I turn the power off completely from PSU switch and once the lights go out from board and I start the system then sometimes the POST is successful, even with the XMP 3200 Profile.
I've had this issue at the start when I bought the board. BIOS version was 2202 at the time.
I asked around on reddit, and there might be a BIOS setting for turning the power off completely upon shut down; I'll try to find that setting when I get back home from work.
POST is successful 100% when running the memory @ default 2133MHz, but I'd love to have it running @ 3200 MHz without the need to reset CMOS before each cold boot. I'm open for suggestions, any help will be greatly appreciated. Thank you in advance
