Question Any 64GB DDR5-6000 (EXPO) kits with native DDR5-5200/5600 chips?

I'm considering upgrading to a Ryzen 7 7800X3D and was wondering if there are any 64GB DDR5-6000 (EXPO) kits that actually have native DDR5-5200/5600 chips, and a profiles for those JEDEC standards along with the DDR5-6000 EXPO profile. I ask this because just in case the memory controller on the CPU I purchase is unstable at 6000 memory speed but stable at the JEDEC 5200 memory speed that is the highest memory speed officially supported by that CPU and I don't expect it to be stable at 6000 memory speed but I expect it to be stable at 5200 memory speed with JEDEC timings and JEDEC voltage.
