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.

Well AMD make a big splash bundle some ddr5 memory with the motherboards. DDR5 aint as price friendly as your motherboards.

Adjusting specific subs is interesting and often has lots of potential. Now we need good quality DDR5-chips that can handle 7000+, Hynix seems alone there now.

I mean, thats a good thing since Ryzen based processors really like higher speed memory. I will be curious what gains you get on Raphael with higher frequencies and where the performance gains start dropping off.

Wow haven’t seen a true troll in awhile. I thought they finally left the internet a year or so ago.

I never knew such a job existed. Learn something everyday.

I was hoping this platform could also run ddr4 but it’s not looking like that. Hopefully jedec ddr5 speeds improve, but I can’t see them getting too high since most CPUs max out at 4.5ghz wo oc. I guess it would be good if ddr5 prices and availability also improved.

Considering DDR is slowly becoming more like GDDR as the number of cores and threads increase and as they find new and innovative ways to share core resources without a massive performance penalty. Maybe trained link DDR with more integrated per core cache or on interposer cache with memory controller as a separate layer.

Just remember

That is definitely the impression this forum gives now.

But anyway, lets see if AM4 can make me switch back again. I like new stuff, not regurgitated cud

Luckily I enjoy both AMD and Intel, it’s great to see both striving hard to earn our money :)

Of course there are people who pick a side and stick with them.. which is somewhat unfortunate. But no need to rub anyones nose in it. Both brands have their own faults and none are perfect.. yet.

AMD showed with it's 5800x3d at least what is comming with Zen4. Sending shivers down Intel's back.

Intel on the other hand flexing by bending their chips. Absolutely hilarious. :laugh: And the deniablity, lol.
They made thermal paste obsolete, because at that flex it will be cooked/dried out in no time. Just use tooth paste.

I would disagree. Agesa 1.1.0.0 got me to max 3800 ram, agesa 1.2.0.0 got me to 4000 but with usb crackling, agesa 1.2.0.3b from last summer was awesome, 4000 stable and no issues. The next agesas has not been worth updating to. The 'issues' have been voltage restrictions for systems running no powerlimit and locked iod volt, but overall often better than agesa pre 1.2.0.3.

Well mine does not flex or bend, good mount and thick back plate, guess your "wit" is moot for me.

That RAM bundling would be motherboard makers option not for AMD to force their motherboard makers into. Right now MSI is bundling some entry level DDR5 RAM with their Z690 boards and that kit while OK is not great for long term use.

Positive noises but proof will be in the pudding. Hopefully we won't be waiting too long to see if there is anything new or better in RAMP.

Time to get the popcorn as this is will be interesting to see all current DDR5 being incompatible from the from the getgo. This makes it sounds like without these extra XMP values, it is just not going to work lol. Though what AMD probably means is that these extra values "enhance" the memory with better sub-timings.
Socket AM5 is expected to be a DDR5-exclusive platform unlike Intel Socket LGA1700, which means no backwards-compatibility with DDR4.
Expect DDR5 to massive drop in price once this happens. Intel Z790 will probably be DDR5 only as well.

I know its the ram manufacturers around every corner who will get the job done but the prices are ridiculously high for building ddr5 setups. Eventually ddr5 is still not a mature performer compared to DDR4. There was a reason Intel chose to have support for both ddr4 and ddr5. While AMD sticking to only DDR5 will put alot of us in waiting list.

I doubt it, given Kaby Lake still supported DDR3, even when most previous gen Skylake builds were already on DDR4.
Meteor Lake on the other hand will most likely be DDR5 only.

Hm, I haven't used much time for RAM overclocking since the legendary BH-5 DDR1 chips..

Overclocked memory that is famous for giving users only a few percent real-world speed advantage, if any at all, is not gonna make a "big splash" with me.

I'm less concerned about more bandwidth and more interested in how AMD is going to get latency down and FCLK speeds up. DDR5 latencies are currently almost double DDR4 latencies and historically FCLK and MCLK have had limited ratio options 1:1 or 1:2, AKA Gear1 or Gear2.

With DDR4, Zen2 and Zen3 really really benefitted from low CAS latencies and the fastest FCLK your CPU could handle.

CAS latency is so important that DDR4-3000 CL12 is significantly faster than DDR4-3800 CL17 in most scenarios and if you're deciding between two RAM kits, the one with the lowest absolute latency should be your first choice.

Depends on what you need in terms of "real-world speed" - most things are perfectly good with a locked 12 ms frametime on variable-refresh displays, which is super easily achievable on Zen3/ADL.
Other things are more low latency focused, which makes them very stutter-sensitive. They want a stable, high framerate, without any massive distracting stutters (very low minimum FPS).

6.7% Increase in average FPS? Pretty meaningless.
17.4% Increase in low-FPS scenarios? Very nice.
68.9% Increase in minimum FPS? Incredible! (visible in a much less "pretty" graph)
