Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000)

[DisEnchantment]

Speculate at will

 

[igor_kavinski]

but how is Ray Tracer MT 63% explained? Almost half score

and why ST -15%?

also Flow Z13 is tiny and probably throttles in full load

There's your answer. I bet we may see a lot of performance unlocked at 150W TDP and better cooling in workstation laptops like Thinkpads, Dell Precisions and HP Zbooks.

The iGPU is also unable to stretch its legs properly and losing to a desktop RX 7600 in OpenCL and Vulkan GB6 tests.

 

[fastandfurious6]

but GB is not even running the igpu these are cpu tests, why put whole max halo in 13'' ulw lol

 

[igor_kavinski]

but GB is not even running the igpu

It is using iGPU in the OpenCL and Vulkan tests.

For a more fair test, someone should power limit their 9950X to 100W and give us the GB6 URL so we can compare.

It will not be representative cause of the different IOD structure

We'll at least find out how gimped the desktop IOD is

 

[poke01]

single core score of Halo should increase in R24 as it scales with bandwidth too.

If it doesn’t that means mobile Zen5 reached it peak with N4, meaning it needs N3E to clock higher.

Very nice if more motherboard vendors announce support. This is going to be awesome publicity for AM5 platform.

Well, that screenshot definitively shows 1:1 UCLK. If this cant be brought to 600 series boards I guess theres finally a reason to upgrade. I can't even get 2x48 to run at 6400 1:1 on my X670E

How much of that is chip lottery on the CPU side too, though? Honestly, not trying to be snarky.

It was my belief that getting 2x2R going at 6400 was entirely chip lottery and that 4x2R at even 6000 was virtually impossible. MSI is proving that wrong with some black magic here. The only way to know is to get more data, as people get hands-on with these configs and try it out.

The black magic I would like MSI to focus on is memory training time. Been using MSI for essentially all AM5 builds so far, used a Asrock Phantom Gaming 870 and holy cow, it was so much faster to boot.

Also, could we get a non-beta firmware update with the goodies available so far please? My new main work PC is rocking this board and I'd like to put a fork in it and call it done!

I think until MSI actually QVLs 4x48GB at 6000+ and/or people are able to get configs similar to this going for themselves without significant effort, it's a bit of a moot point.

If lottery still plays into this and I have to spend weeks testing, tuning, and tweaking voltages timings and resistances, it's a nothingburger IMO

Worked for me thankfully, but I guess it was silicon luck.

They need to finally support 64 GB DIMMs also, not holding out my breath for 96 GBs, but also would have been nice

What board? It might come down to board and bios revision in addition to CPU lottery.

They would have to make 48Gbit packages in order to make 96GB dimms and they aren't. Heck, it's been taking forever just to get 32Gbit packages out to get 32GB SR/64GB DR dimms on the market. We've been hearing about them for years it seems like.

64 GB DIMMs

Are those shipping already?

I've had to get really overpriced one for its built-in 10 GBe - X670E-AORUS-XTREME, maybe that's what helped get mem speed out of the box. Memory is G.Skill Trident Z5 RGB 96GB (2x48 GB) 6400MHz CL32 DDR5, CPU is 7950X3D (in 8 core mode, but it worked fine with 16). No overclocking, so far all stable.

I hope those new mobos will improve ECC timings also, would be great option to have 4x48 GB with decent timings and ECC on.

Are those shipping already?

Maybe not, I was thinking ECC memory here that is available in 64 GB modules, in any case I like having support for such near future stuff being an option, I suspect they just don't want to enable it to avoid competition with low end servers.

 

[MS_AT]

But can you link any DDR5 64GB ECC UDIMM sticks? RDIMM might be available but you won't be able to use them on AM5. After all support for 48GB UDIMM sticks appeared just before the memory itself was available iirc so I wouldn't expect official support sooner.

I have the same board. Are you sure your config is running 1:1 UCLK? Zentimings will tell.

The board defaults to 2:1 above 6000 in my experience. My 2x48GB 6400 kit is on the QVL for EXPO and enabling EXPO forces 2000FCLK and 2:1 UCLK.

 

[Win2012R2]

But can you link any DDR5 64GB ECC UDIMM sticks?

Don't think so, but if we got to 48 GBs, then next is 64, so just saying would have been nice to know if in principle AM5 can support it.

Here is screenshot, seems to be 1:1 or not?

HOW??? I'm going to have to try copying some of those settings.

 

[Win2012R2]

Good luck!

I did not do any manual tuning, I prefer to have system stability vs few percent of extra perf.

 

[Tuna-Fish]

Quite possibly just a better memory controller. I don't think AMD is binning by controller, there is a lot of variability between CPUs.

 

[tsamolotoff]

HOW??? I'm going to have to try copying some of those settings.

Did you put your sticks into the right slots (aka the farthest from the CPU and second farthrest)? 2x48gb is just a dual rank config, should do about the same frequency as single-rank config of the same memory type
