Using two channels of DDR5-5600, you could achieve at most 90 GB/s of memory bandwidth. It seems to me that you would need DDR5-8400 to hit 138GB/s.

- Const-me 3y agoYou might be correct, but do you have a source for that? I found that DDR5-5600 = 69.21 GB/second on that web page: https://www.crucial.com/articles/about-memory/everything-about-ddr5-ram https://www.crucial.com/articles/about-memory/everything-abo... I have tried to find an authoritative source but failed, because DDR5 spec on jedec.org is sold for $370 :-(
- lhl 3y agoYou can use a calculator: https://www.unitsconverters.com/en/Mt/S-To-Gb/S/Utu-6007-3760 https://www.unitsconverters.com/en/Mt/S-To-Gb/S/Utu-6007-376... - enter in 5600 MT/s and get 44.8 GB/s x 2 channels = 89.6 GB/s I have a 7940HS on my desk now and the Memtest reports the same number.
