RAMP is AMD's Answer to Intel's XMP for DDR5

damric · Jan 15, 2022

Before bitching about JEDEC, go join JEDEC. It's free and you can read the newsletter they email you once in a while. There's good engineering articles about what you'll be seeing soon, and many of your questions might be answered. Of course you might learn something and then have even more questions, but at least you won't be bitching on the forum about the bare minimum reliability standard for memory.

It don't on mine.

Yea I always had to manually set the timings in the bios, especially with fail dozer.

For anything above 3200 ... It's chicken and egg. CPU official specs don't go above that for DDR4. Motherboard manuals mention anything over 3200 as overclocking, with no guaranteed speed given. And JEDEC is a standards body.

What about "2933"? I noticed that number seems to be an Intel thing. Seems that Intel considers anything above "2933" overclocking.
And also, it looks like in that Gigabyte X570 motherboard manual, it's lumped in with the "3000" category, albeit it mentions "2933", but not "3000" as well, but does mention "3200", which that manual considers an OC, LOL.

Looks like a lot of recent DDR4 SDRAM, has a "3000" XMP profile. Where did "2933" come from. I suspect it's Intelese.

I have always put it down to how much memory the board could handle and not 4 sticks being supported at that speed. Although it will run without issue at 3600.

Bummer. Haven't changed RAM in a while and it shows.
Is this on the DIMM makers though? Or is it the mobos/UEFIs?

The DIMM makers are the ones that programs the details into the onboard flash no? That info is used by the board makers to set the default speed and timings.

Works fine for me. XMP profile enabled.

I have the same board, never once has it work with my RAM on any UEFI release.

That depends on which generation CPU you have. Intel has gone slowly from 1866/2133 to 3200 MHz as their official memory speed.
6th Gen CPU https://ark.intel.com/content/www/u...76700k-processor-8m-cache-up-to-4-20-ghz.html
12th Gen CPU https://ark.intel.com/content/www/u...2700k-processor-25m-cache-up-to-5-00-ghz.html

2933 MHz worked just fine with my Ryzen 7 1700, whereas 3200 did not, although 3000 worked with a later UEFI/AGESA update.

Looked like Intel possibly still had the "2933" limit on Comet Lake (10th gen, right before that major box art and sticker change, including new logos, which was introduced with Rocket Lake)

But interestingly, only listed "2666" for Core i5 10600K.

I know that on my Ryzen 5 5600X, with the 2666 setting, the latency in AIDA64, really stinks!

It's not amazing with tuned, fast memory either, although I'm a CPU generation behind you. Doesn't seem to have too bad of an impact on most things though.
Note that I'm using comparatively cheap Hynix CJR memory.

Actually, 65ns is what I got at 3200, but days ago, it was 63 ms. Suspect a Windows 10 kernel patch being the cause!

And at "2666", I got a very-Matisse-like 76 ms!

Exactly this, the official Comet Lake specs were 2933 for i7 and i9, 2666 for the rest. I remember because I helped a friend with a 10500 build. (BTW this 10500 is one of the reasons that now I'm considering 12500 or 12600 non-K for my next PC.)

This was known as AMP before, or DOCP

Yea I usually ended up loosening timings a tad or adding voltage with more than 2 sticks in the past... For reliability the former.

It's considered overclocking because it's higher than the spec of the memory controller in the cpu. All modern cpu's have the memory controller on chip instead of the motherboard. This is why sometimes 2 cpus of the same model may overclock different with ram depending on die quality and such. Mobo quality helps with voltage stability (of course psu matters). XMP relates to what they tested /binned the memory to run at. Not a guarantee that it'll necessarily run at that speed with all cpu and mobo combinations, just that the ram is qualified in their labs to run at that setting

Oh god, I forgot that XMP had royalties!

All because JEDEC can't be bothered to create a spec that includes timings and not just frequency!

Intel needs that extra money, cause our tax payer money wasn't enough. Upper management would really be hurting without that yacht club membership

Interesting. Are Viper Steel 3600 on the QVL?

As I've said before, QVL's aren't worth the electricity powering them. The board makers just use whatever RAM they've been given, they don't actually make requests, not do they go out of their way to buy stuff that's popular in the market. You'll find plenty of old stuff you can't buy any more though, in them. Even so, XMP is an Intel standard, so I never expected it to work.

I don't think I'm gonna be an early adopters for these RAMP tech and DDR5 , considering 6000Mhz speed already cost as much as 6700XT :kookoo:

For something really crazy, there are apps now that allow you to set a portion of gpu memory as a ram disk. Finally fast enough storage to handle texture and data streaming in sim city 4 lol (jk a ddr2 ram disk was fast enough)
