Hello guys,
Just built my new z690 PC (12700k, Trident Z5 6000 36CL, Asus Z690-F). As many pointed out with other motherboards, I am unable to run a dual channel config, only being able to slot it 2 sticks in B1/B2 slots. If I try to use any of the other ones, it will not post. Also, the memory speeds will not go higher than 4800, even using XMP (which, btw, is unstable af). I am using the latest BIOS version (0811), did anyone else with the same motherboard as me managed to get dual channel, XMP II stable?.

I had exactly the same issue: My Z690-F would not post with a module in A1 or A1. It posted only with one or both modules in either of the B sockets. I asked the vendor to change the memory, this did not help. After trying for days, I eventually returned the motherboard, got a new Z690-F, and suddenly it worked. I still do not understand what is / was the reason. But given that we have tons of reports here about problems DDR5 modules running in A + B combined channels, I would not be surprised that there is an underlying hardware issue related to the way how the Z690 chipset is implemented on the motherboards.
By the way: You DO run your memory in dual channel config, even when they are in B1/B2. For the simple reason that a single DDR5 module (unlike DDR4) is already running in dual channel mode. It's implemented on a single module by the DDR5 architecture. However, combining A + B channel, will allow you to run in quad mode.

Just ordered a replacement, will keep this post updated with what I find. THanks for the answer Chainbold 🙂 And yes, I know the new DDR5 are actually dual channel, but I was refering to that quad mode 🙂 Have a nice day!

Will be interesting to hear how it goes. In my case, after 2 frustrating weeks, I'm now very happy with my Z690-F and DDR5. Once you get it running, performance is outstanding.

Got the new motherboard, this one was even worse. Some crappy stuff happened with the VRMs located at the I/O side of the board, making it get hot af. I could even hear some stuff going on there, which led me to immediately disconnect the pc. I tried to remove the heatsink from the CPU, which lead me to burn my finger with the temperature of the SCREWS close to the VRM heatsink 😐 some insane design malfunction is going on with the Asus STRIX lineup of mobo this generation. I am returning my entire z690 kit (RAM+MOBO+CPU) to my provider so they test them and try to find me a good combo that properly works.
Quite dissapointed on Asus tbh... just to be clear, my PSU is top of the line: RM850i, so nope, no issues with that.

Yikes, sorry to hear the replacement didn’t work well for you either. I was in an almost identical situation with the ROG Strix z690 gaming F model I got (12900K, Trident Z 5600 MHZ CL36, RM850, 980 NVMe) except I couldn’t get mine to post and the q-led light was orange (dram). Unlike you, plugging the ram into B slots did not work. I found later through some more troubleshooting that the sticker label which says the bios the mobo shipped with was 0403 which doesn’t make sense given the earliest bios is 070X :(. Regardless I tried flashing the bios with the usb function to no avail so at this point I decided to just return mobo and go with different brand. Best of luck and I hope the issue isn’t the ram!
