G.Skill Announces Extreme Low Latency DDR4-3600 CL14 64GB Memory Kit

[milewski1015]

The first Zen 2 chips had sweet spot at 3600 Mhz, but if i remember correct Zen 2 XT models whas capable of 3800 MHz. So i do believe Zen 3 can handle 4 GHz memory.

Wasn't that just because they were guaranteed better bins though? You pay extra for that. The sweet spot is going to be at the lowest FCLK that all CPUs can hit, not just the cherry-picked more expensive bins. Idk, I'm just speculating of course. I think either could be possible but am leaning towards it being 3800 instead of 4000 - maybe 70/30 in terms of confidence level

He wasn't just talking about memory speeds though, but the Infinity Fabric more precisely. The later Zens (I think to be made in China ones rather than Malaysia), that overclock better, generally peak around 1800 for IF. That means you're going to run the memory at 3600, which is what I'm doing. You might be looking at 1900 aka 3800 like he tried to point out. But then again, it's speculation.

I've said it before and I will say it again, I find it very very very annoying that all ram stick sellers don't put the full SPD spec table on the package as per Thaiphoon Burner AND the memory chip manf # so customer can pull that spec sheet also. That should be law IMHO.

If they want to put max speed then they should put in big letters *UP TO 3600, XMP PROFILE, ACTUAL SPEED MAY BE LOWER.

Preach it!

Exactly. You may be able to run your memory at 4000, but it isn't going to worth doing if your IF can't run at 2000. As I mentioned, 3600 is the sweet spot because 1800 FCLK is essentially guaranteed. Yeah, some of the higher binned chips can do 1900 FCLK and run their RAM at 3800, but 3600 is the sweet spot because it's the greatest common factor - you can recommend 3600 memory to a Zen 2 user and be confident that (catastrophically horrible silicon quality aside) they can handle 1800 FCLK to maintain that 1:1 ratio with their 3600 memory kit.

I've stopped really caring about B-Die long ago.

I'll stick with B-die.

I've been on X570 since Dec 2019 and through all the bios updates that have been released I've never had any issues, I however have seen people with non B-die go through incompatibilities issues with certain bios version etc.

Ryzen Dram fast profiles works for me without issue with any bios.

My 3200CL14 Kit can easily run 3600 and the timings of this kit.

When I put in a Zen 3 chip in my board this same kit will probably hit DDR4000 speeds at relaxed timings.

On the AM4 platform its worth it to have solid memory you will save yourself lot of headaches.

For 3600 ok, but I would have to disagree for other speeds. JEDEC goes up to 3200, now if you go buy a 3200 kit, id be willing to bet it's an XMP profile speed and not a std SPD profile. Even the 3200 kit I have, that is the only speed advertised, put it in and 2133 and 2133 is the fastest SPD in there, and one XMP profile at 3200. If you are doing ram upgrades or no OC etc.etc. this is where it is relevant and important. I have even seen 2400 and 2666 kits that are 2133 and the higher speeds are XMP profiles.

That's not because of B-Die but because the boards have incompatibilities. You can't, for example, blame Gigabyte's crappy cold boot issues on B-Die. B-Die is old, and updating it at inane prices doesn't work. E-Die should work perfectly with a proper Zen setup and people have been getting good results. Maybe actually do the research.

Believe what you will I ain't here to make you a believer. I've seen issues in forums from multiple users on different boards running into memory issues with bios versions.

 

[X71200]

That's because they didn't stick it to the QVL maybe? Even if you do, you can sometimes get those issues I spoke about. I actually have like 10 different Zen boards here and have gone through a bunch of stuff. Go on with your fallacy.

Considering I already have a 3800/14 TridentZ Neo kit, I don't see how this is extreme.

64GB! I doubt it. These are amazing timings for 4 sticks.

 

[Kokotas]

Nice! Hope we can see the difference from 3200 cl14 soon.

 

[Mussels]

the sweet spot for ryzen... drool

 

[John Naylor]

That would be redundant. There's no JEDEC spec for DDR4@3600, everybody knows that requires running the memory in overclock mode.

The store listings make no mention of the JEDEC compliant speed and timing on the saled fliers.

The number on the package and on the spec sheet is always the XMP speed. JEDEC speed does bot appear on the . If it can not maintain that speed. it is returnable ... been there done that, never questioned.

It will reach those speeds, but on XMP-capable motherboards.

It will reach those speeds, but on XMP-capable motherboards.

I mean, it's a bit of a double bind in terms of what is promised. The XMP profile tells us the memory is capable of these speeds at these timings when used in conjunction with a motherboard and memory controller capable of the same. Motherboards and CPUs don't explicitly support memory speeds that high, but often mention them as overclocked options. So there's no guarantee no matter what; if your IMC or motherboard is bad, it doesn't matter if the RAM is good. Zen and Zen + were excellent examples - you could obviously buy RAM to use with a system with a CPU based on those architectures with a 3600 XMP profile, but it was also nearly 100% certain that it wouldn't run at that speed. Is that the fault of the RAM, i.e. grounds for returning it outside of the initial return period? Obviously not, as other components are the limitation. But I sincerely doubt any store would argue that point - what do they stand to gain? And how many people are buying RAM that overspecced to begin with?

And that only describes every label on every product out there...

For XMP? Absolutely.
