Hello!

I am looking for parts that I'll eventually buy & use for my next build, next year.

I am looking for DDR5 RAM modules that run at the fastest possible speed by default @1.1V, no XMP.

This is the fastest DDR5 kit I came across:
Corsair SKU CMK32GX5M2A4800C34 (2x16GB DDR5-4800 CL34 @1.1V)

Question 1:
Is there a faster kit out there that I don't know about?

Question 2:
Is there a faster kit, or an equally fast kit out there, to the one that I've mentioned which is of 64GB (2x 32GB)?

So, you think that a power user (and moderator) of the Gigabyte USA Forum didn't know that?

Yes, I do think that. I've seen not only moderators that don't know their own crack from a hole in the ground, but also supposedly specialized tech support people from these companies who lack even basic knowledge that any number of veteran members or moderators here understand to be commonly accepted standard policy. And besides that, just because somebody is a moderator on the Gigabyte forum doesn't mean IN ANY WAY that they are ACTUALLY knowledgeable about hardware or specifically know anything relevant about memory configurations or architectures.

I see moderators all the time that lack basic hardware knowledge and we point and laugh at them. All the time. Most sites don't promote moderators because they are knowledgeable, although it's certainly helpful, they usually do it TO MODERATE, meaning they are level headed, mature and not prone to whims or childish behaviors. (Although this is not true for every site. Many sites have moderators that are not only NOT knowledgeable, but power trippers and jerks as well) They are good at administrating fairly. That is why they are moderators. Not because they are spectactularly knowledgeable.

Hello!

Here are some of my findings on this topic (JEDEC DDR5):

1. Corsair SKU CMK32GX5M2A4800C34 (2x16GB DDR5-4800 CL34 @1.1V)


2. ADATA AD5U560016G-S (16GB DDR5-5600 CL45-45-45 @1.1V)
https://www.memoryc.com/memory/ad5u560016g-s.html


3. Team Group TPSD516G5600HC4601 (16GB DDR5-5600 CL46-46-46 @1.1V)

They will all likely perform very close to each other. The 4800 will actually be faster if you run it at cl34 but the spec says the standard rate is cl40 and when you run it that rate it is a tiny bit slower than the other modules.
The speed memory runs at is only 1 variable in the performance all the latency numbers also matter a lot

Yes Bill, but if he starts making changes to the timings or anything else, you are immediately introducing the same potential "instabilities" that he is "worried" that running XMP will introduce. Which of course, it won't, but hard to argue with somebody that is seemingly sure of the potential problem.

It would be no different than ANY other change in configuration from whatever "just happens" when you assemble and boot the machine. ANY change, has the EXACT same potential for "It's not just working". And, incurs the probability that you need to test for stability, no different than any manual overclock. If you EVER change the timing, voltage or frequency, you MUST test the configuration to ensure it is stable, otherwise you are a fool.

No. I am not doing that.
I am looking for JEDEC high-speed DDR5 RAM, just as fast as the Kingston DDR4-3466 CL19 @1.2V was.
There are no DDR5 modules like that yet.
We'll see...

This module runs at 1.2V
JEDEC/PnP being:
DDR4-3466 CL19-23-23 @1.2V

Which doesn't matter WHATSOEVER because there are no consumer platforms that can support default 3466mhz memory speeds. The fastest speed supported by both the 13900k and Ryzen 9 5900x, which are the highest default memory speed supporting platforms that still supported DDR4, is 3200mhz.

So the difference between the JEDEC profile and any other XMP profile of 3466mhz on that module is, nothing. There is NO difference. It is the EXACT same thing because that speed is not natively supported and in order to USE that speed you would need to either manually configure the memory or choose one of the XMP profiles onboard. You are fighting a battle that there is no possible way to win. AND, this thread is now become a waste of time for everybody involved, especially you, and is almost beginning to look more like trolling because it's been clearly pointed out several times now and you insist on a belief in something that is on the one hand entirely unrealistic (Memory just automatically changing itself to different speed without something else causing it) and on the other that you are going to somehow automagically find a kit that avoids having to abide by the known native speed support, which is not going to happen.

Years from now, you may be rewarded by a massive 7% increase in performance when newer platforms begin supporting DDR5 6000mhz speeds natively, but even that will likely be somewhat damped if you're using two or more modules based on the current population support speeds. Native speeds went out the window as an expected baseline MANY years ago and anybody tying themselves to that level of performance just basically is either using the wrong platform (Should be using a workstation or enterprise platform with ECC memory and more of it) or is just challenged.

Well, you COULD be in luck, but I suspect that it's expensive and of course it will require that you pursue only a platform that will allow you to use ECC memory. I believe SOME of the Z790 and X670e motherboards DO support ECC memory, so you could get your 6400mhz AND be ensured of absolutely error free memory operations regardless that enabling a profile will be required. Funny that it happens to "become a thing" at exactly this time. Still, since it's the ONLY option you have, it IS an option.

That is not true!
This memory module and all of its variants are listed on the QVL of the Gigabyte Z390 Aorus Master, and on the QVL of most Gigabyte Aorus motherboards!
And yes, they run at those parameters by default (no XMP needed)!
Please check your facts before typing infos like that!

Jesus dude. You're really not getting it.

No, YOU are the one who is wrong. The QVL list has LITERALLY NOTHING to do with whether memory runs at JEDEC configurations or not. It's LITERALLY only a SMALL sampling of memory that has been confirmed to WORK on a given board. For some memory kits that speed WILL be at the JEDEC spec because the kit itself falls within that spec no matter what profile you enable on it. Others are validations that the XMP profile has been confirmed to work on it at the advertised speed. None of it has anything, at all, to do with what you are trying to indicate it has to do with and with that I'm done here because it's like trying trying to talk to a wall. Good luck to you sir.

The kit is running at those parameters by default on all motherboards that has the kit listed on the QVL, hence "JEDEC/ Plug-N-Play"!

Please talk facts, not your own suppositions!

mainboard QVL ok, that maybe, but its still outside of CPU support...so same as XMP, going above cpu supported clock voids CPU warranty in case of hardware failure due to overclock, even if you have mobo and ram able to run higher than what memory controller is specced for
Click to expand...

The JEDEC spec is more about the voltage and less about the frequency.

If in order for those parameters to run, a higher voltage is needed, then it is called "overclock", or "eXtreme Memory Profile".
But if a memory module hits high-speed frequencies without the need of higher voltages, then it is called "optimization".
