G.SKILL Announces Trident Z5 Royal Neo Series DDR5 Memory with AMD EXPO, Up to DDR5-8000

[Gmr_Chick]

You can buy the none "NEO" on Newegg. Considering the NEO just has a EXPO profile instead, they are practically the same thing. Different QVL lists is all.

Ryzen 9000 will be here soon, lets hope the price isn't $$$$

I always thought it was better to look for AMD EXPO certified kits when pairing RAM with the 7000 series, to avoid possible problems?

It is, but if you know what you are doing with timings etc you can get any kit. Even with expo some kits have really lax base timings and you want to tighten them up my 6000 Cl30 kit has terrible timings out of the box.

You aren't wrong. Tech support is just going to tell you to disable XMP or buy a EXPO certified kit.

Besides a few extra values included in EXPO, these are the same.

Depends on your IMC, RAM die, cooling and motherboard.

It's still not 1:1 BTW, as the IF is still running at 2000 MHz similar to AM4/Zen 3, so it's more like 3:2:2 where IF is 2000 MHz, IMC and RAM at 3000 MHz if you're running 6000 MT.

Or 1.5:1.

Would be 3:4:2 if you went up a gear to do 8000 MT or whatever.

Zen 4 testing with various config:

As you can see putting clocks out of sync can be slower.

If they keep that 3:2:2 why isn't sweet spot 7200, not 6400? IF runs at 2400Mhz in Zen 5. So how can 6400 be sweet spot unless it's some bizarre non-integer ratio?

Unconfirmed it runs at 2400.

Really! This is from AMD's own slides from the architectural deep dive a few days ago: AMD Zen 5 Deep Dive

These new changes have resulted in a significant IPC uplift averaging 16% versus Zen 4. In certain cases, the Zen 5 core can reach up to +35% IPC such as (Geekbench 5.4 AES XTS) and another key area that has been improved upon is the L2 and L3 cache structuring. AMD also made some significant changes to the IMC which now result in much higher EXPO/XMP memory support and the Infinity Fabric clock has been raised from 2000 MHz on Zen 4 to 2400 MHz on Zen 5 with DDR5-5600 speeds natively supported.


Unless wcftech got this wrong somehow? Also MLisD has been stating 2400MHz for last 6 months too.

There’s nothing in the slides that actually states the IF clock. Pretty sure GN and other more reliable tech sites would’ve commented on that if it indeed leaked. Won’t be long till we know for sure.

*Also curious, I don’t remember seeing a bar/entry for “I/O clock” in ryzen master on my 7900X which also happens to be 1200 (1/2 2400).

Infinity Fabric clock has been raised from 2000 MHz on Zen 4 to 2400 MHz on Zen 5

If it is indeed 7200 1:1 on ZEN5, that's awesome!

We have to wait and see what the maximum 1:1 enabled memory speed on ZEN5 will be (officially on July 31st) when the reviews are out (or maybe it's a day earlier, IDHK).

Ryzen 9000 will be here soon, lets hope the price isn't $$$$

Fingers crossed.

The infinity fabric and Memory Controller are two different things.

For Zen5 it probably only a small jump to 2200 for FCLK and 3400 for memory controller. But we will find out next week.

 

[Sunny and 75]

Can't wait.

@dgianstefani

Could you add Vcore to the table as well? I mean, when we go from 6000 EXPO to 6400 Fully Tuned as an example, does Vcore stay at the same value or does the value increase?

Curious to know more.

That excludes me then, lol. I know very little about timings and thus don't want to create more problems for myself
