What RAM kits can reach 5600Mhz without Intel XMP?

I’m expecting my AMD7840U framework to come in this quarter and would like to get the RAM ordered. For my purposes I need a 2x32gb configuration, and want a kit that is stable at 5600Mhz with a CAS latency of 40.

On paper this, should be easy to find, but i’ve read that some kits only hit 5600Mhz with intel XMP and will be throttled to 4800 on systems that don’t support XMP. Do we have any known good kits that will check these boxes yet? Thanks!

I got " KF556S40IBK2-64" (Kingston Technology Fury Impact 64GB (2x32GB) 5600MT/s DDR5 CL40 Laptop Memory Kit of 2), and, before I bought it, went to the Kingston website to verify that the “default” was at 5600 MT/s, that will let you know what the “native” configuration of the RAM without need to custom XMP settings.


Crucial 2x16GB DDR5 5600 SODIMM kit (CT2K16G56C46S5) works at 5600 MT/s out of the box.


Post 555 in the Batch 1 Thread I have Kingston 5600 CL40 without XMP Running and made some test and compared against Rembrandt

I got the same kit and so far, it works great !


I am using G.SKILL Ripjaws DDR5 SO-DIMM Series DDR5 RAM 32GB (2x16GB) 5600MT/s CL40-40-40-89 (F5-5600S4040A16GX2-RS).

Works at 5600 MT/s CL40 as advertised.

I also ordered a Crucial 32 GB kit (CT2K16G56C46S5), but one stick was DOA. I think it’s a little slower at CL46.
