X670E PG Lightning Memory issue with EXPO

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I face difficulty to set up my memory properly.

Setup:

MB: X670E PG Lightning
CPU: AMD Ryzen 9 7950X3D 16-Core Processor
Memory: Corsair DDR5 6000MHz CL30 Vengeance Grey EXPO (64GB 4x CMK32GX5M2B6000Z30) it is even on the list of supported memories
BIOS/UEFI: 2.08.AS01 (also tried with 2.02 initially)

If i use only 2 modules then EXPO profile works and runs at 6000 MHz, but as oon as i add another 2 modules then it crashes and can get working only at stock frequencies (3600?). 

Is there any idea how I could get them running on their nominal frequencies?
I'm hoping some uefi update will fix this issue.

	Hi There... Booting with 4 dimms is very hard on the memory controller, official supported speed is DDR5-3600mt for 4 dimms, it can be done(I`ve done it myself at 6400mt), Here`s a screenshot of my timings.. https://mega.nz/file/xuQShRoA#tpAR5KuD9ST-6Qto4La9_It0lNTXAaGEsK4KODoieKk

	Is there any tool that can help me find out the correct settings? I'm not really an expert on the topic.

	Hi there... there aren't any tools to config ddr5, however a lot of information and help can be found at : https://www.overclock.net/threads/amd-hynix-ddr5-overclocking-guide.1801842/#replies It looks daunting, but once you get the basics right its a lot easier...
