We've already seen some official and some leaks of various DDR5 modules and now Corsair's Dominator Platinum RGB modules have leaked. Alongside the pretty pictures, we also now know that these will be 5200 MHz/MT/s modules with a timing of 38-38-38-84 and that they'll require 1.25 V at these settings. Corsair has carried over its Capellix LEDs and iCue support, although this was pretty much expected.

Details of three sets of DDR5 memory from Kingston have also leaked and it looks like the company will have at least three main SKUs. What we're looking at is the ValueRam series with bog standard JEDEC spec at 4800 MHz with a CAS latency of 40, the Fury Beast which will feature the same clocks, but improved an CAS latency of 38 and finally a higher clocked Fury Beast SKU at 5200 MHz which a CAS latency of 40. All three SKUs will come in single 16 GB modules or 32 GB kits.
 
So many DDR5 leaks, but I haven't seen any leaks of very high speed memory. 
 
 
 

ADATA says they overclocked their XPG DDR5 to 8100, but no idea of the voltage they were pushing.
 
By the time I'm ready to do a couple of more builds, DDR5 will be more mature.
