I'm running the Asus Rampage VI Extreme with an i9 7940X and 32Gb of G.Skill TridentZ RGB DDR4 (4 x 8GB) 288-Pin 3600 (PC4 28800) P/N F4-3600C16Q-32GTZR Memory.
I've updated the Bios to the latest version 1002 as well. The board Posts fine and defaults to a 2133Mhz 1.20V memory setting. With everything else left at default settings I change the Ai Overclock Tuner setting to 'XMP'. The memory specs are detected just fine - 3603 at 16-16-16-36, 1.35V.
When I save and restart, the Post hangs with the display code on the board reading "Code AF: Detect Memory". I have to clear the CMOS and it Posts just fine back into the Bios with the original default 2133Mhz 1.20V setting.
I installed all 4 modules as per the instructions in the motherboard manual (DIMM B1, A1, C1, D1 slots). With XMP enabled I manually override the frequency and can't get past 2800Mhz.
The next step up is 2933Mhz. When I try that frequency the board hangs during POST with "Code AF: Detect Memory". I have to clear the CMOS to get it to boot back to default settings.
I then tried each module individually installed in the DIMM C1 slot as per the manual. Each module behaved the same way. I could not get past 2800Mhz and each one made the Motherboard hang during POST if set to 2933Mhz or higher. The same POST code also appears - "Code AF: Detect Memory".
In the past all one would have to do is bump up the DRAM voltage slightly but from everyone that has posted on the ASUS forums they have no issue with this kit running at 1.35V.
I'm tempted to RMA this kit but not really sure it's the memory.
Is there another setting in the BIOS I should change to make this kit work or could this be a bad kit?
Note: This Kit is on the ASUS DRAM qualified vendor list as well.
I seem to recall that when I first booted the board with the original 0702 BIOS I changed the AI Overclock Tuner to 'XMP' and it rebooted into the BIOS just fine with the new speed of 3603Mhz. After I updated to 0802 I think that's when I was starting to have problems I listed above.
I tried to switch to the second BIOS to see if it's still at 0702 and test it but pushing the BIOS switching button does not work. The LED for the #1 BIOS stays lit.
Could this end up being a bad board since the BIOS switch won't even work.
