Question: Z690 Maximus Formula with 13900K memory speeds

I currently have a z690 Formula mother board with a 12900K paired with Team Group DDR5 @6400 CL40. Overclocking the memory has been a nightmare. *In fact, getting the XMP up and running with tighter timings was a labor love. I have seen some promising overclocks from switching to a z790 mother board and 13th gen CPU, well into the 7000 range on the same memory kits that wouldn’t budge above 6200 on a z690/12th gen combo.

My questions are:
1) Can I keep my z690 Mother board and upgrade just my CPU to take advantage of the improvements to the memory controller/speeds/stability? or is it a package deal?*

2)If I were to pair a 13900k with my existing z690 Board, what features would be unavailable to me? *And in everyday use, would I be able to tell? **

Thanks in Advance for any help that can be provided.*

hi, i have a z690 Hero and a 13900k and in my experience I can barely overclock my memory. I have a gskill 6600 kit and I can get it to run at xmp just fine but I can't even overclock to 6800 even with looser timings. I can tighten my timings a little but not much. I was hoping to get the kit at least to 7000 but it's a no-go, not sure if it's the ram or the board...

Hello,

6400MT is the maximum validated frequency for the Z690 Extreme. For best chance of plug and play compatibility, opt for a kit on the QVL 1 or 2 ratios below maximum validation.

There is definitely a MASSIVE improvement with 13th gen and memory. While my board uses ddr4 swapping cpu's allowed for an instant 300mhz bump with the same exact timings and voltages
