Nice and it's with 24GB density sticks I think that was what surprised me actually :laugh:

What does this mean? I'm assuming that the preferred ratios remain. Does this mean it's now possible to use four DIMMS in a stable system? Is this possible as an EXPO overclock? Nice number but guidance is needed.

From CPUZ screenshot it seems FSB: DRAM its 1:4 Ratio.

With Gear 4 lol. That's garbage.

You mean gear 2

Incredible. I never would've thought this was possible with a firmware update alone... :twitch:

Curious to see where the new "sweet spot" lands for Zen 4.

I still wait for AGESA 1.2.0.A on my Gigabyte B550 Aorus Pro and X570S UDs.....so yeah maybe get some engineers from EVGA and do it.

Nice step I want to see how Ryzen 7 7800x3d gaming benchamrk with 8000 mhz ram

Its not just Gigabyte. Asus and Asrock too.

Improvements are improvements, the second article suggests the 1:1 performance has also improved and now consumers will be able to tweak internal IMC parameters, sounds good to me. Better than being told there will be no further improvement without a new motherboard chipset revision. :)

Hopefully @ir_cow later adds credibility to these reports.

It definately makes AM5 a good bit more interesting. The 7800X3D is going to really dominate that much more now giant CPU cache and much higher bandwidth system memory when you do run into cache miss scenario's. Very interesting development for certain.

If AMD themselves say due to IF speed, DDR5 6000 is the sweet spot, how will this be good for AM5 platform?

Shou MikoNice and it's with 24GB density sticks I think that was what surprised me actually :laugh:

why use this specific density? any pros with this particular amount.

Minus InfinityIf AMD themselves say due to IF speed, DDR5 6000 is the sweet spot, how will this be good for AM5 platform?

That applies to Zen4.
I am pretty sure these are not the last CPUs on this platform. ;)

Od1sseasWith Gear 4 lol. That's garbage.

There's no such thing as "gear 4". AM5 runs IF and IMC decoupled already. Otherwise 1:1 would mean that since IF is at 2000 then IMC should not be more than 4000 and obviously no one is running DDR5 at 4000.

How is it not? Besides the statement you mentioned was made at a time when DDR5 was expensive and 6000 was pretty much the max anyway.

There are 3 clock domains on Zen4 regarding memory. There is FCLK, UCLK, and MCLK.
FCLK is the infinityt fabric clock which is desync on Zen4. UCLK is IMC clock which is usually 1:1 with MCLK (the IO clock of the memory half of its data rate).
So yes the Zen4 has been running the equivlent of Gear 1 the whole time with the UCLK / IMC clocking to 3000Mhz on DDR5 6000.
On Intel there isn't even the option of running Gear 1 on DDR5. It defaults to Gear 2 and auto switch to Gear 4 at very high data rates.

ZubasaThat applies to Zen4.

More importantly that was when the platform launched. They've had plenty of time to refine bios optimizations as well as just MB designs on either yet to be launched MB designs as well any any that launched after the initial launch that were a of a bit higher quality. You've also got more memory kits available today of higher quality and affordability. I think it's a bit of a combination of all of those things coming together being reflected. Basically a bit of maturity to the entire ecosystem. Plus Intel's official memory support was even less ambitious.

Biggest thing that stands out to me is better motherboard designs and optimization along with better and more affordable memory kits are available today. I mean why wouldn't things be a bit better now realistically if there has been inroad improvements to memory and motherboard support as we well cost considerations? I can't really fault AMD/INTEL not officially supporting the most outlandishly early binned memory kits and MB designs when some of these architectures were more new and recent.

If you look at anything launching now however you're expectations are going to be a bit higher probably compared to when DDR5 was more in it's earlier infancy. It's a bit beyond that very early adoption phase now even though it's still relatively newish.

debwhy use this specific density? any pros with this particular amount.

It's new and depending on how good your cpu's mem controller is it can have a easier time to run 24GB than 32GB at higher clocks.

I saw that on ZEN3 seen some people in my country that got custom builds with the Ryzen 9 5950X cpu's with 32GB at 3600MT/s memory in they finish testing before the were shipped out and passed memory and stability test but not a week after there were issues booting and running memory at 2966MT/s fixed the issue and testing with other memor didn't make a difference the mem controller was degraded.

Still waiting for that bios release, got 192Gb@5200 now, Aorus Master, 7950x3d.

Sorry because wcc. Records of DDR5 speed on AM5. Up to 9058MT/s

HaunterStill waiting for that bios release, got 192Gb@5200 now, Aorus Master, 7950x3d.

With f13a running now on Aorus Master, 7950x3d stable on 192GB@5600MHz. Do you have some advice how to change BIOS settings to reach e.g. 6000? Change latencies? Right now I got as I posted here on our Czech forum:
