AMD today addressed multiple issues with its 3rd generation Ryzen processors through a highly-recommended update to its Chipset Driver software. To begin with, it stated that several users noticed anomalous behavior with 3rd generation Ryzen chips where the voltages and clock-speeds would be raised as the processor would misinterpret low-scale performance requests from certain software as a request to unlock higher performance states (combinations of higher clock-speeds and voltages to support them). This first came to light when users reported abnormally high voltages at idle when performance was measured by certain software that caused the Observer Effect. The new version 1.07.29 of AMD Chipset Drivers refine the AMD Ryzen Balanced Windows power scheme to be more aware of low-priority workloads and ensure the right state when the system is idling. AMD recommends Ryzen Master software. Version 2.0.0.1233 (or later), as they have fixes to the hardware monitoring module.

The AMD Chipset Drivers 1.07.29 also includes a "beta" fix for the bug that rendered "Destiny 2" unplayable on machines powered by 3rd generation Ryzen processors. The company had earlier tried to fix this bug through an update to its AGESA processor microcode, through ComboAM4 1.0.0.3ABA, although that particular version, not to be confused with the widely circulated 1.0.0.3AB, was found to be buggy and pulled. AMD said it's working on a newer version of AGESA, version ComboAM4 1.0.0.3ABB, which will include "a more comprehensive solution" to the bug affecting "Destiny 2."

AMD fixed a bug that caused "Destiny 2" to be unplayable on 3rd generation Ryzen processors, through updated chipset drivers. The company had, earlier this month, released an update to its processor microcode with the AGESA ComboAM4 1.0.0.3ABA update (not to be confused with 1.0.0.3AB), before pulling it for causing other bugs. Ahead of its publication on AMD website, Robert Hallock, the company's technical marketing head for processors, posted a Google Drive link to the driver's installer. It bears the version number v1.07.26.0551, and is marked beta. Hallock comments that this is a "workaround" to help "get you into the game." It looks like a more permanent solution to the bug still lies in updating the microcode, once AMD figures out what went wrong with 1.0.0.3ABA.

The latest version of AGESA ComboAM4 microcode that enables 3rd generation Ryzen support on AMD 400-series chipset motherboards has been deemed buggy and pulled from motherboard vendors. AGESA ComboAM4 1.0.0.3ABA (not to be confused with 1.0.0.3AB that's being widely distributed), was originally released to fix an application crash noticed with "Destiny 2." The microcode inadvertantly destabilizes PCI-Express on motherboards, with users of ASUS motherboards complaining of stability issues with the latest BIOS updates that include 1.0.0.3ABA.

Peter "Shamino" Tan from ASUS commented that the company was under a tight schedule to push 1.0.0.3ABA out as BIOS updates, and didn't have the time to properly validate it. "We just got told to pull (was undergoing validation prior) 1003 ABA version," he said, adding the root cause of the problem being "that PCIE speed of BXB-C downgraded from gen4 to gen2,..." He comments "so its not surprising that bugs emerge since the source has hidden bugs that only gets unraveled with thorough testing. combine that with trying to get firmwares out in a tight time frame, kinda damn if you do (release firmware quickly) and damn if you dont (dont release firmware quickly) situation." It's interesting to note that in their BIOS update change-logs, quite a few motherboard vendors omit the full version string of AGESA. You may encounter ComboAM4 1.0.0.3AB being referred to simply as "AGESA ComboAM4 1.0.0.3."

MSI is among the motherboard manufacturers who had to significantly modify their UEFI firmware packages to cram in AGESA ComboAM4 1.0.0.3ab microcode on their AMD 300-series and 400-series chipset motherboards, due to firmware ROM size limitations. Most older MSI AM4 motherboards have 128 Mbit (16 MB) SPI flash ROM chips, which proved insufficient to integrate the latest AGESA microcode alongside its feature-rich ClickBIOS 5 UEFI setup program. MSI addressed the issue on two fronts. For its existing motherboards that have 128 Mb flash chips, it released BIOS updates that have AGESA 1.0.0.3ab, but shed some bulk on the setup program, by replacing ClickBIOS 5 with the "GSE-lite" setup program. The company is also releasing newer revisions of many of its AMD B450 chipset motherboards anticipating demand from the section of 3rd gen Ryzen buyers who don't want to spend at least $170 on an AMD X570 motherboard.

These revised motherboards feature "MAX" in the name, and come with 256 Mb (32-megabyte) SPI flash ROM chips, enabling MSI to combine AGESA ComboAM4 1.0.0.3ab with ClickBIOS 5, and not compromising on any of the motherboard's BIOS-level feature-set. These motherboards also come with out-of-the-box support for all of the 3rd generation Ryzen processors launched so far, as indicated on the box. The boards also retain support for A-series "Bristol Ridge" and "Raven Ridge" Athlon APUs that had faced the axe with the latest BIOS updates. The B450 Tomahawk MAX and Mortar MAX are characterized by matte-black heatsinks replacing silver; while the B450-A PRO MAX has the "MAX" logo clearly printed on the VRM heatsink. Pricing of these boards are expected to be on par with the models they're replacing.

ASUS believes that PCI-Express gen 4.0 support on older socket AM4 motherboards based on the AMD 400-series chipset is technically possible, even if discouraged by AMD. The company's latest series of motherboard BIOS updates that expose PCIe Gen 4 toggle in the PCIe settings, does in fact enable PCIe gen 4.0 to all devices that are directly wired to the SoC. These would be the PCI-Express x16 slots meant for graphics, and one of the M.2 slots that has PCIe x4 wiring to the SoC. Below is a list of motherboards scored by Chinese tech publication MyDrivers, which details the extent of PCIe gen 4.0 support across a number of ASUS motherboards based on the X470 and B450 chipsets.

AMD apparently did not explicitly block PCIe gen 4.0 for older chipsets. It merely suggested to motherboard manufacturers not to enable it, since the newer AMD 500-series motherboards are built to new PCB specifications that ensure PCIe gen 4.0 signal-integrity and stability. ASUS wants to leave it to users to decide if they want gen 4.0. If their machines are unstable, they can choose to limit PCIe version to gen 3.0 in their BIOS settings. Among other things, AMD's specifications for 500-series chipset motherboards prescribe PCBs with more than 4 layers, for optimal PCIe and memory wiring. Many of the motherboards on ASUS' list, such as the TUF B450 Pro Gaming, use simple 4-layer PCBs.

Our Monday story chronicled how MSI inadvertently erred in giving many of its AMD 400-series chipset motherboards 128 Mbit (16-megabyte) SPI flash ROM chips instead of larger 256 Mbit (32-megabyte) ones, which nearly jeopardized the company's "Zen 2" support deployment, forcing it to greatly thin its motherboard firmware feature-set, and break SATA RAID support on many of its boards. To be fair to MSI, the company may not have anticipated the AGESA microcode growing tremendously in size with its latest ComboAM4 1.0.0.3-series. We are now hearing from Polish tech publication PurePC that MSI has scrambled to remedy this by re-releasing many of its AMD 400-series chipset motherboards with larger 256 Mbit SPI flash ROM chips.

The PurePC report states that MSI will brand the revised motherboards "MAX" in the product name (eg: B450 Gaming Pro Carbon AC MAX, B450M Bazooka MAX, etc.), although we don't know if the new model names will have the company's latest MEG/MPG/MAG prefixes. The 256 Mbit SPI flash ROM chip allows MSI to cram in AGESA 1.0.0.3a, which lets you use 3rd generation Ryzen processors to their full capabilities (barring PCIe gen 4.0 on these motherboards of course). More importantly, the larger ROM chip allows MSI to have AGESA 1.0.0.3a without sacrificing on its feature-rich Click BIOS 5 UEFI setup program, SATA RAID module, or losing support for any of the socket AM4 processors.

AMD succeeded in delivering on its backwards-compatibility promise for the 3rd generation Ryzen processors on motherboards based on AMD 300-series and 400-series chipsets. This promise was very close to being derailed suggests a community thread on MSI forums. According to MSI representatives active on the forum, the capacity of the SPI flash EEPROM chip that stores the motherboard UEFI firmware is woefully limited to cram in the AGESA ComboAM4 1.0.0.3a microcode on many of its motherboards.

The company had to make several changes to its UEFI BIOS package that's currently being circulated as a "beta," to accommodate support for 3rd generation Ryzen processors along with AGESA ComboAM4 1.0.0.3a. First, it had to kick out support for A-series and Athlon processors based on the 28 nm "Bristol Ridge" silicon. Second, it had to [and this is a big one], kick the RAID module, breaking SATA RAID on many of its motherboards. Third, it had to replace its feature-rich Click BIOS 5 setup program with a barebones "GSE Lite" Click BIOS program, which lacks many of the features of the original program, and comes with a dull, low-resolution UI. This program still includes some essential MSI-exclusive features such as A-XMP (which translates Intel XMP profiles to AMD-compatible settings), Smart Fan, and M-Flash.

AMD will launch its 3rd generation Ryzen 3000 Socket AM4 desktop processors in 2019, with a product unveiling expected mid-year, likely on the sidelines of Computex 2019. AMD is keeping its promise of making these chips backwards compatible with existing Socket AM4 motherboards. To that effect, motherboard vendors such as ASUS and MSI began rolling out BIOS updates with AGESA-Combo 0.0.7.x microcode, which adds initial support for the platform to run and validate engineering samples of the upcoming "Zen 2" chips.

At CES 2019, AMD unveiled more technical details and a prototype of a 3rd generation Ryzen socket AM4 processor. The company confirmed that it will implement a multi-chip module (MCM) design even for their mainstream-desktop processor, in which it will use one or two 7 nm "Zen 2" CPU core chiplets, which talk to a 14 nm I/O controller die over Infinity Fabric. The two biggest components of the IO die are the PCI-Express root complex, and the all-important dual-channel DDR4 memory controller. We bring you never before reported details of this memory controller.

MSI mid-March began quietly rolling out BIOS updates for its socket AM4 motherboards based on AMD 400-series chipset, with a very ominous BIOS change-log entry: "Support new upcoming AMD CPU." At first, we dismissed this for being the company's follow-up to its 6th March announcement of support for some of the newer Athlon processor models, namely the 220GE and 240GE. After updating our MSI B450 Gaming Pro Carbon AC with one of these BIOSes, however, we discovered a very interesting microcode string - AGESA COMBO-AM4 0.0.7.2.

Such a major change in AGESA shouldn't be warranted to add support for two new chips based on existing "Raven Ridge" architecture that both AGESA "Summit Ridge" and AGESA PiR (Pinnacle Ridge) series microcodes should be able to comfortably run. We spoke with sources familiar with AMD microcode, who revealed that this AGESA COMBO-AM4 0.0.7.2 is designed for the upcoming "Zen 2" microarchitecture, and its first socket AM4 implementation, codenamed "Matisse." AMD internal versions of AGESA with Matisse support begin with the version sequence 0.0.7.x., and as we head closer to formal launch of these chips, AMD could release a 1.0.0.0 version of "AGESA COMBO-AM4." For our B450 Gaming Pro Carbon AC, the BIOS version packing this new AGESA is v1.60, and we wager this board should now be able to run Ryzen "Matisse" engineering samples. Now, if we can only get our hands on one.

MSI late November released BIOS updates for its entire range of socket AM4 motherboards, mainly to include AGESA 1.0.0.6, which improves memory compatibility. The updates also pack various motherboard model-specific fixes. Apparently there has been a goof-up with this update (not in a bad way, though). The latest BIOS updates "accidentally" unlock the otherwise locked Athlon 200GE dual-core processor with integrated graphics.

No, you won't get more cores or iGPU stream processors, but the base-clock multiplier letting you easily overclock the processor is now unlocked. This adds value to the $55 processor, given that competing Celeron and Pentium Gold SKUs are overpriced in the market these days. In their overclocking adventures with the 200GE paired with a MSI B450 Gaming Pro Carbon AC motherboard, TechSpot observed that the chip (which is clocked at 3.2 GHz by default) wouldn't POST beyond 3.90 GHz, and that you need vCore at 1.4 V to sustain even 3.90 GHz. They found 3.80 GHz at 1.35 V to be 100% stable (an 18.75% overclock). The memory clocks are still restricted to DDR4-2666, although you can still play with timings.

AMD, in an interview with Overclockers UK (OCUK), confirmed that its second-generation Ryzen desktop processors will support the existing AM4 socket, so current Ryzen platform users can seamlessly upgrade to the new processors, with a BIOS update. Most current AM4 socket motherboards will require BIOS updates to support Ryzen "Raven Ridge" desktop APUs, and Ryzen "Pinnacle Ridge" CPUs, as the two require an update to the latest AGESA 1.0.0.7 version. In the interview, AMD representative James Prior confirmed that the company plans to keep AM4 its mainstream-desktop processor socket all the way up to 2020, which means at least another two to three generations of processors for it.

The next generation is "Pinnacle Ridge," which is rumored to be an optical-shrink of the "Summit Ridge" silicon to the 12 nm process, enabling higher clock speeds. The decision to keep AM4 doesn't mean the company's 300-series chipset will be made to stretch over 3 years. The company could release newer chipsets, particularly to address 300-series chipset's main shortcoming, just 6-8 older PCI-Express gen 2.0 general purpose lanes (while Intel chipsets put out up to 24 gen 3.0 lanes).

ASUS recently released BIOS updates for its socket AM4 motherboards based on AMD X370 and B350 chipsets, which implement AGESA 1.0.0.7, which as you'll recall, paves the way for implementing support for upcoming processors, based on AMD's Vega-infused "Raven Ridge" APU silicon, and the 12 nm refreshed Ryzen "Pinnacle Ridge" silicon due for February 2018. ASUS published, and later withdrew the BIOS updates as the media got whiff of them.

The next parts for AMD's mainstream-desktop socket AM4 platform will be Ryzen "Raven Ridge" APUs, which let you finally use the HDMI and DisplayPorts on your motherboards. "Raven Ridge" combines a quad-core "Zen" CPU with a 640-stream processor integrated graphics based on the "Vega" graphics architecture. The "late-2017 or early-2018" time-line for these chips still appears to stand. RedGamingTech suggests that AMD's answer to Intel "Coffee Lake" processors, the 12 nm Ryzen "Pinnacle Ridge" processors, could be out by as early (or late) as February 2018. These chips could be previewed or teased at the company's events held on the sidelines of the 2018 International CES.

AMD is readying an update to its AGESA micro-code. AGESA is an essential component of AMD platform motherboard BIOSes responsible for starting the processor at system start-up. Updates to it improve the motherboards' memory and CPU compatibility. Following its all-important AGESA 1.0.0.6 update that vastly improves memory compatibility of AMD Ryzen processors, the company is readying an even newer version. The new AGESA 1.0.0.7 update prompts significant changes to the structure of motherboard BIOSes, making it easy to implement support for upcoming socket AM4 chips, such as the "Raven Ridge" APUs, and the 2nd generation Ryzen "Pinnacle Ridge" CPUs.

Professional overclocker elmor, who is currently associated with ASUS ROG, responding to an Overclockers.net forums question about the Crosshair VI series motherboard, mentioned that AGESA 1.0.0.7 significantly changes the BIOS structure of AMD motherboards, which will make it easier implement support for future processors. "AGESA 1007 comes with support for Raven Ridge APUs. AMD has also changed the entire BIOS base structure so we have to do a lot of work to port everything to the new version, which may result in further bugs. The advantage is that it makes it easier to support future CPUs (Raven Ridge, Pinnacle Ridge)," he said. Updates to AGESA are distributed by motherboard manufacturers as BIOS updates.

A new DDR4 overclocking record was achieved by Australian overclocker "newlife", breathing new life towards Ryzen's memory frequency support. Don't just count your fireworks right now, though: while impressive the result came with some caveats in the form of the user's Ryzen 5 1400 CPU: it was down-locked to a paltry, performance-murdering 800 MHz.

After shipping with what could be considered by some as broken DDR4 memory support, AMD's Ryzen platform has in the meantime received the proper amount of care such a pivoting product for AMD should. A series of AGESA updates which improved AMD's performance in gaming, as well as DDR4 memory support have been under distribution since the platform's launch, and those updates have surely worked towards achieving this record today. The score was achieved with a single 8 GB G.Skill Trident Z E-die memory kit, which is usually rated for 3600 MHz frequencies (F4-3600C17-4GTZ), using 18-20-20-58-93-1 timings. This module was seated on a GIGABYTE AORUS AX370-Gaming K7 motherboard (F4 BIOS).

AMD today posted an updated compatibility list of DDR4 memory kits for Ryzen processors. While just about any DDR4 memory kit will run on socket AM4 motherboards, a limited few have been tested by AMD to run reliably at speeds such as DDR4-3200, DDR4-2933, DDR4-2667, and DDR4-2400. AMD's new compatibility list contains a wider selection of DDR4 memory modules that have been tested by AMD to work reliably on Ryzen processors.

To make the most of these modules, however, AMD asks you to look out for and install motherboard BIOS updates which contain the AGESA 1.0.0.6 micro-code update. This should be prominently displayed in the change-logs of BIOS updates from motherboard manufacturers, and the latest batches of motherboards should come with AGESA 1.0.0.6 pre-installed.The revised DDR4 compatibility list can be accessed here.

AMD is readying a new stepping of its 14 nm "Summit Ridge" eight-core CPU silicon, which powers its socket AM4 Ryzen processors, according to Canard PC. The new B2 stepping reportedly addresses a lot of hardware-level errata which cannot be fixed merely by AGESA updates. According to Canard PC, the changes seem to be focused on the uncore components of "Summit Ridge." Typically, uncore refers to the integrated northbridge, which includes components such as the memory controllers, PCI-Express root complex, etc.

If the B2 stepping is mostly focused on uncore-level errata, it could mean improved PCI-Express device support, and perhaps even memory support improvements beyond even what AGESA 1.0.0.6 brings to the table. Canard PC reports that it hasn't come across any CPU core-specific errata being addressed with the B2 stepping. The glaring FMA3-related bug has been patched through BIOS updates, and most newer batches of socket AM4 motherboards come with the patch pre-installed.

It turns out that the EVO X AMD Edition isn't GeIL's only AMD Ryzen-optimized DDR4 memory, with the company unveiling AMD Edition variants of pretty much all its DDR4 memory brands. This includes the EVO Potenza, EVO Spear, EVO Forza, Super Luce, Pristine, and DragonRAM series. Each of these "AMD Edition" branded memory kits has been stability-tested with AMD Ryzen processors, at their advertised clock speeds and timings. They come in a variety of speeds, including DDR4-2400, DDR4-2666, DDR4-2933, DDR4-3200, and DDR4-3466; in densities of 8 GB and 16 GB, making up 16 GB and 32 GB dual-channel kits, respectively.

It's not known if all of these are based on Samsung b-die DRAM chips. AMD spokespersons have publicly stated that Samsung b-die isn't the only DRAM chip needed for high memory clocks on Ryzen processors, and that even with older versions of AGESA, certain memory kits with SK Hynix and Micron DRAM chips are having some success in achieving high memory clocks. AMD is working to improve support for faster DDR4 memory kits through updates to AGESA, which will be dispensed through motherboard vendors to end-users, as motherboard BIOS updates.

You've probably heard of AMD's AGESA updates by now - the firmware updates that are ironing out the remaining kinks in AMD's Ryzen platform, which really could have used a little more time in the oven before release. However, kinks have been disappearing, the platform has been maturing and evolving, and AMD has been working hard in improving the experience for consumers and enthusiasts alike. As a brief primer, AGESA is responsible for initializing AMD x86-64 processors during boot time, acting as something of a "nucleus" for the BIOS of your motherboard. Motherboard vendors take the core capabilities of AGESA updates and build on them with their own "secret sauce" to create the BIOS that ultimately populate your motherboard of choice. The process of cooking up BIOS updates built on the new AGESA will vary from manufacturer to manufacturer, but AMD's Robert Hallock says you should be seeing BIOSes based on this version halfway through the month of June - if your vendor isn't already providing a Beta version of some kind.

This new AGESA update code, version 1.0.0.6, should be just up the alley of enthusiasts, however, in that it adds a grand total of 26 new parameters for memory configuration, improving the compatibility and reliability of DRAM, especially for memory that does not follow the industry-standard JEDEC specifications (e.g. faster than 2667, manual overclocking, or XMP2 profiles). Below you'll find the 26 parameters that were introduced.
