ASUS Points Assertion on Ryzen 7000X3D Processor Points, Attainable Voltage Points with AMD EXPO

Yesterday we reported that MSI announced a wave of firmware updates designed to handle and alleviate potential points with customers on AM5 utilizing AMD’s Ryzen 7000X3D processors with 3D V-Cache. One of many most important adjustments with MSI’s newest UEFI firmware for AM5 included voltage restrictions when utilizing Ryzen 7000X3D collection CPUs in order that these chips could not be overvolted because the V-Cache packaging is considerably delicate to further energy.

Additional to MSI’s announcement, ASUS has launched a press release to skilled engineer and excessive overclocker Roman ‘Der8auer’ Hartung, which addresses the potential problem with utilizing AMD’s EXPO reminiscence profiles along side the Ryzen 7000X3D collection chips. One of many key parts that seemingly surrounds the issue is using AMD’s EXPO reminiscence overclocking profiles.

ASUS’s Director of World Product Advertising and marketing and Technical Advertising and marketing, Rajinder Gill, mentioned in a press release to Der8auer, “The EFI updates posted on Friday comprise some devoted thermal monitoring mechanisms we have carried out to assist defend the boards and CPUs. We eliminated older BIOSes for that motive and in addition as a result of guide Vcore management was obtainable on earlier builds.” Rajinder additionally mentioned, “We’re additionally working with AMD on defining new guidelines for AMD Expo and SoC voltage. We’ll problem new updates for that ASAP. Please bear with us.

Trying on the narrative of the assertion supplied to Der8uaer from Rajinder, we will verify that ASUS has certainly eliminated older iterations of its firmware for its AM5 motherboards. Trying on the EMEA facet of issues, on the time of writing, the latest firmware update to be posted on the ASUS product pages is dated 04/21/2023, which signifies ASUS lately up to date the firmware, however the replace is not the most recent one in query.

Roman ‘Der8auer’ Hartung’s Ryzen 9 7900X additionally has a bulge.

The one factor these points have in widespread is that AMD’s EXPO reminiscence profiles have been utilized, claims Roman ‘Der8auer’ Hartung, and even highlighted that his Ryzen 9 7900X processor additionally fell foul the the ‘bulging problem.’ That is notably fascinating as this is not an X3D collection chip with 3D V-Cache, though we’re not conscious of another studies of non-X3D Ryzen 7000 chips being affected presently.

Enabling EXPO reminiscence profiles on Ryzen 7000 processors does a number of issues to the processor that pushes it past the technical specification of the chip. Chief amongst these is elevating the SoC voltage and another main voltages, resembling VDDIO, that are used to feed the IOD. Like every ASIC, there are limits to how excessive voltages may be safely pushed, and that is one concept behind the reason for the current run of broken Ryzen studies. Although how this is perhaps related to the problem being centered round Ryzen X3D chips – the place the voltage-sensitive V-Cache is on the CCDs and their separate voltage aircraft – is unclear presently.

In any case, this does underscore why AMD’s EXPO reminiscence overclocking profiles void the guarantee on these chips, as there’s extra to EXPO than simply ramping up reminiscence frequencies and making use of extra voltage to the DRAM itself.

Additional to Rajinder’s assertion given to Der8auer, ASUS’s Senior Technical Advertising and marketing Supervisor, Juan Jose Guerrero, posted the following statement on Twitter Tuesday afternoon:

“A number of AMD Ryzen 7000X3D house owners have reported CPU and motherboard failures. We acknowledge the incidents/points and have been speaking with AMD to research the doable causes. Now we have additionally contacted affected customers to offer help and gather further info.

Ryzen 7000X3D processors don’t enable for CPU ratio or CPU core voltage tuning (CPU overclocking) however do enable for efficiency tuning and DRAM overclocking by way of PBO2 and EXPO reminiscence. To help EXPO and/or reminiscence overclocking at DDR5-6000 and past, SoC voltage needs to be sufficiently elevated to make sure compatibility and stability. The quantity of voltage required varies between CPU samples. Some processors are extra delicate to overvoltage than others, and a few are succesful at operating increased reminiscence frequencies without having as a lot voltage.

As confirmed with AMD, any intentional manipulation of those settings can harm the processor, socket, and motherboard. To mitigate this, we’ve been working with AMD to outline new guidelines for EXPO reminiscence and SoC voltage. To assist defend the CPU and motherboard, we’re issuing new EFI updates to restrict the utmost obtainable SoC voltage to 1.3V.

We advocate updating your motherboard UEFI BIOS to the most recent launch. Please additionally make sure the CPU is cooled adequately. Our suggestion is to make use of a minimum of a 240mm AIO liquid cooler or high-performance air cooler. When you have been affected, please don’t hesitate to contact ASUS help on your area.

As we talked about in our article yesterday about MSI addressing CPU voltage on their own AM5 motherboards, distributors need to tackle any extra potential points, following a small-but-concerning variety of studies circulating on Reddit that their Ryzen 7000X3D processors are burning out and killing the motherboard within the course of. ASUS’s assertion and the abstract of the firmware on the official product web page point out that ASUS is fearful about SoC voltage, and as such, the brand new firmware locks it right down to 1.30 V. Which ASUS states is to ‘defend the CPU and motherboard.’

On the Chinese language product web page for the ROG Crosshair X670E Excessive, the firmware has been up to date as of right this moment (on the time of writing) to 04/25/2023, and the firmware model in query (1302) does seemingly tackle the SoC voltage.

Additional to ASUS’s and MSI’s statements, AMD has officially responded with a statement of their own:

It reads, “We’re conscious of a restricted variety of studies on-line claiming that extra voltage whereas overclocking could have broken the motherboard socket and pin pads. We’re actively investigating the scenario and are working with our ODM companions to make sure voltages utilized to Ryzen 7000X3D CPUs by way of motherboard BIOS settings are inside product specs. Anybody whose CPU could have been impacted by this problem ought to contact AMD buyer help.”

In fact, these problems with Ryzen 7000X3D collection processors burning out aren’t simply restricted to these utilizing MSI and ASUS motherboards. Because the preliminary studies, customers have reported further points on numerous fashions and types throughout threads on Reddit. The potential for harm is without doubt one of the main causes AMD locked down the X3D collection processors in order that customers could not manually overclock them. Even the primary iteration, the Ryzen 7 5800X3D, was additionally locked down.

One factor stays clear: AMD and its motherboard companions at the moment are formally investigating the matter, and customers with affected Ryzen 7000 CPUs are suggested to contact AMD buyer help straight.
