AMD Ryzen 7000 "Zen 4" Processors Have DDR5 Memory Overclocking Design-Focus
AMD's first desktop processor with DDR5 memory support, the Ryzen 7000 series "Raphael," based on the "Zen 4" microarchitecture, will come with a design focus on DDR5 memory overclocking capabilities, with the company claiming that the processors will be capable of handling DDR5 memory clock speeds "you maybe thought couldn't be possible," according to Joseph Tao who is a Memory Enabling Manager at AMD.
Tao stated: "Our first DDR5 platform for gaming is our Raphael platform and one of the awesome things about Raphael is that we are really gonna try to make a big splash with overclocking and I'll just kinda leave it there but speeds that you maybe thought couldn't be possible, may be possible with this overclocking spec." We are hearing reports of AMD innovating a new overclocking standard for DDR5 memory, which it calls RAMP (Ryzen Accelerated Memory Profile), which it is positioning as a competing standard to Intel's XMP 3.0 spec.
For its current desktop platforms with DDR4 memory, AMD offers A-XMP, a UEFI firmware-level innovation that translates settings from XMP profiles into AMD-compatible settings. RAMP will be different, in that in addition to the usual memory clock-speeds, main timings, and voltage values, it will include many of the finer memory settings that are specific to the "Zen 4" memory controller.
"Raphael" Socket AM5 desktop processors will be AMD's second processor to support DDR5 (assuming it launches before EPYC "Genoa."). The company's Ryzen 6000 "Rembrandt" processors based on the "Zen 3+" architecture already come with a DDR5 memory interface. Socket AM5 is expected to be a DDR5-exclusive platform unlike Intel Socket LGA1700, which means no backwards-compatibility with DDR4.

And it is an entirely serious post, if delivered comedically - power users are important for helping regular users not misconfigure their system, and suffer.
Unfortunately "misconfiguring" has been extremely easy on AM4, so I hope it will get harder to mess up - and easier to correct - on AM5.
1. You don't see 0.2 percentile values much. It can mean just one minor stutter that you don't even notice.
2. The data shown is way above 200 fps with all configurations. I can't even tell the difference between 60 and 80 fps, let alone 200.
3. This is one single game - a hand-picked example from among all the games, the majority of which are GPU-limited unless you have an extremely slow CPU.
4. (Edit) The data for this graph was taken with a mid-/high-tier graphics card at probably low game settings. No one in their right mind would play a game like that. You're always going to be GPU-limited at higher settings and/or with a more affordable card.
Edit 2: Just to illustrate what I mean: A 100% difference between 25 and 50 fps is significant, but a 100% difference between 100 and 200 fps is nothing because you can't see it. At that 25 to 50 fps range, you're GPU-limited 99% of the time. The remaining 1% is a hard CPU limit. You can't pair a fast, modern CPU with such slow RAM that will bottleneck it in a perceptible way. Ever. ;) Unless you're playing on your iGPU that is.I just find it funny that nearly everybody is a manager of something nowadays.
If you won't give 'em more money, just give 'em a title, I guess. :toast:
I saved my overclocked SPD timings to XMP2 on my RAM (yeah, it's a thing. we have a thread on it) and some of the values simply dont get read, and rely on automatic timings. Huge latency difference with manual tweaking, huge waste of time, too.
If they can fix that situation up from the start with better translation from XMP and better automated settings (tight/loose default options) it could make some very big changes for user friendliness (loose option would make 4x sticks a lot easier to run) and performance (tight auto settings for the common 2xsticks of ram setup)
I would love to see them doing higher clocks on mem.
