Latest AMD AGESA that Nerfs Ryzen 7000X3D Voltage Control Also Limits Memory Overclocking

[btarunr]

The latest AMD AGESA 1.0.0.7 AM5 platform microcode that the company recently released to improve stability of machines powered by Ryzen 7000X3D processors, more importantly, prevent them from physical damage due to increased voltage in voltage-assisted overclocking scenarios; reportedly impacts memory overclocking capabilities, too, reports g01d3nm4ng0. The "PROCHOT Control" and "PROCHOT Deassertation Ramp" toggles that were available in the oldest versions of AGESA for AM5, are not available in the latest production AGESA.

The memory compatibility is also affected. AMD recently added support for odd-density DDR5 memory modules, such as 24 GB and 48 GB, which make up 48 GB and 96 GB 2-module (dual-channel, four sub-channel) kits. It is possible to max out 192 GB, but while the older AGESA 1.0.0.6 allowed memory frequencies of up to DDR5-6000 with SoC voltage of 1.3 V, the newer AGESA is only stable up to DDR5-4400 at this density. To be fair, most motherboards advertise maximum memory frequencies of under DDR5-4800 for memory configurations where there are two DIMMs per channel, and both DIMMs are dual-rank (so four dual-rank DIMMs in all, which is the least optimal memory configuration from a memory frequency and latency perspective).

AMD’s biggest weakness is the memory controller. It needs improvements across the board (pun intended).

I hate it when I'm right.

It's not an issue with the normal 2 dimm 32gb config. I have no issues running 6000cl30 with 1.0.0.7

My friend updated the bios on his Asrock board and reports 2x32GB works just fine @6000 CL30 as well.
The board defaults to 1.24/1.25V on SOC.

" the newer AGESA is only stable up to DDR5-4400 at this density" that's complete BS.
1.3V SOC is enough for 4x16GBGB 6000.
you barely need more than 1.15V for 2x16GB 6000 CL30.

You predicted 24 GB and 48 GB memory configs would be clock limited after this update? Wow that’s a pretty specific prediction. Kudos to you! I would have never predicted that this specific memory configuration would be only effected.

1.3V SOC is enough for 4x16GBGB 6000.
you barely need more than 1.15V for 2x16GB 6000 CL30.

Don't forget that it needs to work on 100% of the setups, not only your use case.

Did you even read the article and entire sentense of what you quoted ? "At this density" which is 192gb...

Just like Ryzen 1000, weak memory controller fixed by Ryzen 3000(to a lesser degree even 2000). Unfortunately we have to wait for new CPUs.

If previous OC capacity introduced a hardware risk than it's natural for 1.0.0.7 to nerf it.

Personally speaking, I wanted a 7800X3D but its European price really threw a blanket on this. For a gaming rig, it's very useless to run a hard RAM OC, it changes really nothing, there's close to no difference between 6000Mhz/CL32 and faster RAM in most benchmarks

Manually tuning a kit is upwards of 5% free performance, even when you can only go as far as tightening timings or getting 6200 with solid timings on AM5.

Most review sites don’t have the time to actually “overclock” memory, and never provide more information than scaling at xmp/expo settings.

Well this will make future memory reviews interesting...

My 2x16 GB GSkill EXPO profile became unstable after my BIOS update (DDR5 6000 CL 30 at 1.35V). Which memory are you all using that keeps the speed and latency but is stable?

It's overclocking... so it doesn't need to work on 100% of the setups.

 

[Slizzo]

@btarunr , Not all of the BIOS released were on AGESA 1.0.0.7. MSI's BIOS that was released for the SoC voltage issue is still on 1.0.0.6.

So are gigabytes as of now.

Which motherboard and memory modules do you have? I'm currently using an Asrock board + 2x16 GB G.Skill expo memory as well, but I haven't updated the bios yet and not sure if I should already now

that's a good average. let it be + - 20mv and you still have a headroom of around 100mv.

I have a ROG STRIX X670E-F (my god what terrible naming) BIOS 1401, with G.SKILL Flare X5 32GB (2 x 16GB) DDR5 6000 (PC5 48000) Model F5-6000J3038F16GX2-FX5

 

[Psychoholic]

Also using Flare X5 6000, rock solid stable, and im on the beta bios 1.0.0.7 agesa.

Jealous of you. RE4 Remake won't last more than 20 minutes with EXPO engaged... Turn it off and it's perfectly fine.

Do you mean 1410? 1401 is still 1.0.0.6 afaik. Sounds like your memory overclock itself is unstable if you’re tuning timings. It may not be the case with all CPUs but 1.2-1.25 VSOC should typically be enough for 6000-6200.

ASUS’s X670 boards do seem to be a mess though.
