G.SKILL Trident Z Royal DDR4-4000 MHz CL15 2x8 GB

[TheLostSwede]

INteresting. I bought some cheap DDR4. Crucial Ballistix Sport. XMP 3000. OC'ed it to 3733MHz (optimal for ZEN2 according to AMD), latencies to 16,19,19,19,39 and got 67,1ns latency and almost the same read/write/copy speeds. 53000MB,29800MB, 49400MB No need to waste money on this.

It's more of an issue with the reviewer missing some settings, technically this kit should have a latency of below 65 at these speeds.
Did you try 3800MHz?

Results do seem weak for such an expensive kit.

This is my Hynix kit with trash auto timings. Cheaper and double the capacity.

Yes. It actually increases latencies and decreaser R/W/C speed. Like AMD said, 3733 is the sweet spot for ZEN 2. The infinity Fabric hits a speed limit and isn’t stable past 3733MHz, so above that speed we break the 1:1 Fclk ratio

3733 is NOT the sweet spot. And 3800mhz is the highest memory frequency that can be run while maintaining the ideal ratio on the IF. I don't know where you get the idea that the IF is not stable past 3733mhz, that is NOT TRUE.

That depends on how you configure it, it runs fine for me. I think you ended up at 1:2 if that's what happened. You might have to set the IF speed manually at 3800MHz, as not all motherboards does that automagically. Some chips are supposed to do 3866MHz these days. That said, you have a 3600 which is a lesser bin, so that could be why.

Depends on the CPU, he only has a 3600, so it might not be able to do it.

I gave you the link (that you included in the quote). Read before posting.

I have the same ram but the RipjawsV variant (not this shiny tridentz) with the same specs and I've bought two kits so I run 4x8GB (32GB total), getting pretty much same results on AIDA benchmarks
except the memory latency which I get around 44.8, is it because I run 4 sticks ? or maybe because I have weaker CPU (8700K) ? wondering if going for 4 sticks did actually decrease my performance and I should maybe remove 2 of them (they were sold as a kit of 2, so I just ordered 2kits.. and yes they work without crashes/issues although didn't run memtest or some stuff maybe I'll try)

You can easily test this by removing 2 sticks but I also get a slight penalty on my 9900k using 4 sticks vs 2 around 40-41ns.

What's your link have to do with it. The testers didn't even test 3800mhz lmao. And that changes nothing about the maximum memory frequency for Ryzen 2 which is 3800mhz. This is RYZEN 101.

That may be so but he didn't word it in a first person tense.

AMD themselves said 3733MHz is the sweet spot. We are talking about frequency at which infinity fabric and memory clock are at 1:1 ratio. If you think higher frequency automatically means higher performance, You are greatly mistaken my young Jedi. About a great many things. You know more than AMD engineers who made the CPU? Send them your CV please.

Don't be a daft fool. Those slides have come in a variety of numbers from 3600 to 3800. The fact is this, 3800mhz is the fastest the IMC on Ryzen 2 can run while still maintaining the 1:1 ratio. That you do not realize this shows how wrong you are. Below is AMD stating the new tweakers maxim of 4000mhz as compared to the previous maxim of 3800mhz. Slides aside, you clearly don't know.

It's auto Fckl-uckl 1:1 ratio in BIOS. Up to 3733MHz. Beyond that you can manually set fclk frequency in BIOS in 33MHz steps, up to 3000MHz in my case with the latest BIOS. For overclocking and uckl/fclk to 1:1 ratio. If it works...great. But auto settings stay at 1 :1 up to 3733Mhz. I'm done with you.

I honestly do not get it... why does G.Skill cover their best product(s) in unicorn puke and fairy dust?

Why can they not offer plain, matte black heatspreaders on their top tier kits, like they used to do with the TridentZ?

If all anyone cares about is looks, put the B.F.ugly heatspeaders on the crappy low-bin kits, and sell the good stuff with plain heatspreaders to those of us who care about performance, not sparkles and pretty lights.

Would probably buy silver, taped that rocky up part and spray painted. If one cant buy what he wants, there is always option to mod it.

Hope TechPowerUp uses this memory to review the 5950x / 5900x.

Yes, they should keep it for test purposes

Overclocked result looks like usual B-Die bin, good stuff

IF clocks above 3600 MHz are considered an overclock.

Introducing CPU overclocking into memory reviews adds a variable that could otherwise be avoided.
