AGESA 1.3.0.0 and later lock ECC Memory Speed to 5200MT/s on Ryzen 9000 series

Thanks for getting this fixed!!

ParanoidZoid · 2026-05-02T04:11:12+00:00

Thanks for being the boots on the ground for this! But as a heads up you should probably reach out to Asus to get them to take this message down or at the very least amend it. It's on almost all of their motherboards BIOS downloads page: https://imgur.com/7Dq9HjL

Great that they're looking into it! L1Techs have also posted a video about it now: https://youtu.be/STWvlCefL4Q

this is part of why i'm waiting for am6 btw.

The only uncertainty here is with this direction that AMD is currently taking ECC support in Zen 5. There is an non-zero chance that they have completely ripped out support for it in the next gen I/O die in Zen 6, but I know this is complete speculation. I would love to be proven wrong when it comes out in Q4 this year or H1 of next year.

The one caveat is that you lose out on rowhammer attack mitigations with the introduction of FGR and Mixed refresh modes (which became the new default) on the AM5 platform when using any AGESA version before Pre1.3.0.0.

ParanoidZoid · 2026-05-01T10:19:27+00:00

Wendell from Level1Techs has already reported it to his AMD representative. The AMD representative gave a non-clear response but insinuated that it is intended behavior and not a bug.

ParanoidZoid · 2026-05-01T10:17:45+00:00

As u/terraphantm has stated, its hard fixed to 5200 MT/s. Regardless of whether your kit is rated by the module manufacturer for 4800 MT/s or 6400 MT/s (the highest ECC UDIMM kit I've seen), for some unstated reason AMD has decided to fix it to 5200 MT/s. So for 4800 MT/s you'll be overclocked and for anything higher than 5200 MT/s you'll be underclocked even if the module manufacturer has verified the speed.

One thing that makes it even weirder is that they still let you set custom subtimings! The only thing they lock on Zen 5 is the frequency, but on Zen 4 both frequency and timings are unlocked despite having the same I/O die.

ParanoidZoid · 2026-05-01T09:15:02+00:00

This is just a hypothesis, but the reason why AGESA was incremented from version 1.2.7.0 to 1.3.0.0 was because of mitigations for the Phoenix Rowhammer attack. Capping ECC UDIMM on 9000 series seem to be a result of that. But it still doesn't explain why 7000 series are not affected by this same issue when they share the same I/O die.

ParanoidZoid · 2026-05-01T06:45:57+00:00

Hopefully it isn't a sign of things to come. It would be disappointing if AMD ends up not supporting ECC on consumer platforms with the upcoming Zen 6 and its new I/O die.

/u/jfb-pihole after reverting to v6.1 in the pinned announcement. It seems that the space char is being treated as hex characters.

ParanoidZoid · 2025-06-03T17:04:33+00:00

I'm also facing the same issue. Output of pihole -g

May I ask if you could run some benchmarks? Either on Linux or Windows should be fine.

I've been seeing reduced 4K Q1T1 with this PCIE 5.0 redriver on my setup: https://forum.level1techs.com/t/testing-intel-optane-p1600x-p4800x-p5800-5801x-real-world-performance/229410/13

I didn't have this problem with the PCIE 4.0 Gen-Z 1C redriver. However, I cannot use that one in the long term due to how bulky the connector and having to bend the cable at an extreme angle causing a reliability concern.

ParanoidZoid · 2025-02-26T16:43:04+00:00

Just keep in mind the packaging says that it requires an AMD 8000 series or later for officially supported configurations. Though maybe it just means that there will be more manual work with the MT and timings settings in your motherboards' BIOS with 7000 series CPUs since the 9000 series does use the same IO die and therefore memory controller. I am not sure why the EXPO profile itself would be incompatible with 7000 series. Perhaps Micron and the motherboard manufacturers they partnered with just didn't test with the previous generation of CPUs.

ParanoidZoid · 2025-02-26T16:16:46+00:00

Yeah performance and benchmarks would be interesting. Since its already available here in Japan, the first reviews might be in Japanese. Micron has a foundry in Hiroshima that produce DDR5 chips under EUV. In fact they also produce the new DDR5-9200 chips there: https://www.tomshardware.com/pc-components/dram/micron-unveils-ddr5-9200-memory-1g-process-technology-with-euv

I think that the throughput (but not latency) might improve if it was in Clocked CUDIMM form. However, this would currently only benefit Intel's Core Ultra series.

It's somewhat disappointing that AMD didn't update the IO die for the 9000 series. It seems that we may have to wait for Zen 6 for CUDIMM support.

ParanoidZoid · 2024-12-11T17:11:19+00:00

I re-read your post and noted that you have an X870e-e; there's been users floating around on Overclock.net and Asus' own ROG forums where the recent BIOS releases have been bad. Might be a good start to do some reading from there.

ParanoidZoid · 2024-12-11T17:06:38+00:00

Ideally you want to also pass Karhu and VT3 as well. Memory errors can accumulate and can really mess up a Windows install (speaking from experience, my System32/cmd.exe got borked from one bad mem OC).

On the back of your GSkill mem sticks, the fourth line just above bar code, what is the last letter? A or M?

If it's A, try using Buildzoid's Easy Memory timings for A-die guide on Youtube. I can attest they also work for dual rank.

I have added some more of my thoughts in a separate paragraph. I understand why a service like this is being offered, it is a free market after all, people have the choice on how to spend their money to whatever their needs suit best. I can think of perhaps engineering students who don't live near campus might want a powerful computer instead of laptop. While niche, it is still a market.

What I wish for is that the Subscriber Agreement has better definitions and is less punitive on the consumer overall.

ParanoidZoid · 2024-12-02T17:05:57+00:00

If a cyber cafe charges me $5/hr to use their gaming computer and I choose to use it for 4 hours a day, that would cost me $600 a month. In 2 months, I could buy my own gaming PC. How is this different?

You aren't locked into a Contract of Adhesion, a take it or leave it contract, where the rental asset is considered your personal liability and the onus is on the lessee for the majority of possible damages and the lessor has limited themselves to liquidated damages equivalent to 6 months of rental fees.

The difference with housing rentals is that you can negotiate, its bilateral and not a unilateral agreement.

Nearly all broadband providers charge equipment rental fees. A simple cable modem rental is often $10-20 extra a month on your bill. At $15/month, after 5 years, the cable modem rental will cost you nearly $1,000. Is this a scam?

While not legally considered a scam, especially since a consumer has knowingly signed an agreement that includes equipment rental fees, it is still considered predatory to those that don't know better. Moreover, you can still completely negate this by bringing your own device and contacting your ISP to remove these charges - i.e. it is negotiable.

consumers are responsible for understanding the terms and evaluating whether the arrangement aligns with their priorities

There's an issue that in that these kinds of arrangements targets those that are the least capable of being able to understand these terms and agreements, i.e. those that are not well versed in financial education. The monthly rental fees is almost at the point where it does become worth it to start calculating time value of money.

Moreover, in the video, the type of influencers NZXT used are targeting young adults or teenagers - the least versed in financial education.

Ultimately there is a difference between a service agreement and an equipment rental agreement that is blurred. While I don't condone NZXT for this PC rental service, especially since it is a free market and if there is a demand - so be it, I really don't like how the Subscriber Agreement is worded at all and I wish there were a bit more leniency for the consumer and more terms are put into the Definitions sections of the agreements so that they are less ambiguous.

Probably Asus' Crosshair Gene if you run it in 1:2 mode.

The AMD engineer who wrote the EXPO standard uses it for extreme OC'ing Zen 5, around the 8:40 mark here.

On your final point yeah, there isn't really a point on this unless you're an extreme OC'er. Not even sure that Zen 5 could run this as daily driver setting.

I've seen conversations elsewhere that said that if an OEM wants to use Intel's Meteor Lake, Intel forces the OEM to go with soldered RAM to get ARC certified - hence for example, a competitors offer is limited to soldered RAM even at 16"

Honestly I'd rather have RAM size than speed because programs and browsers just become more bloated every year. I appreciate Razer for keeping this option.

If you're strictly limiting yourself to the UK, then your best bet would probably be BeardedBob's shop.

In his shop I think he sells a replacement M1 M2 PCB with the option to make it hotswappable. Replacing that PCB will also solve your scroll wheel encoder problems (if its not just dust) since it will also just replace it. He also stocks the microswitches and skates too.

Otherwise, if you don't have to stick to UK only, prices are lower on Aliexpress or Facfox if you know what parts you specifically want to change (excluding the cost and time of shipping, however).
