Rome Epyc 16, 24 and 32 cores sub 200w TDP - 2133 vs 3200 effect on workloads that require multiprocessing over compute

[jamesdwi]

I recommend only using DDR4 3200 MHz for EPYC 7002 and 7003 processors. DDR4 2133 MHz was the standard in the Intel X99 era when DDR4 memory was introduced. DDR4 has plummeted in price providing a great value for most types of memory. DDR4 3200 MHz is the latest and greatest DDR4 memory standard (excluding gaming memory). This is a comparison of the slowest DDR4 memory versus the fastest.

Will a 7003 memory controller access faster than the memory speed it was designed for, EPYC cpus are enterprise server cpu, they are designed to be stable, 24/7 in my experience, they run exactly as spec'd a 5% improvement isn't worth instability, these aren't consumer gaming systems where a 10 minute reboot means you reload a game.

7002 and 7003 is designed for 3200. It is NOT a mere 5% improvement.
What really affects the IF clock which is tied to memory!
They do 3200 all day long it's not 2015 anymore

man my dyslexia must of kicked in really hard yesterday... i swore I read it used 2300, now I look at the order for the 7403p I placed yesterday and see even it is shipping with 3200 DDR4 ram. You are totally right.

What type of 3200 memory did you get?

The kit arrived and it was well packed and in pristine condition. The memory is:
Samsung 32GB 2Rx4 PC4 - 3200AA - RB2 - 12 - DC1
