AMD Confirms X470 Motherboards Will Not Get PCI-e 4.0 Support

AMD clarifies that motherboards with 300 and 400 chipsets will not receive support for pci-e 4.0. According to AMD, it would cause confusion if this were the case. AMD also confirms that Ryzen 3000 processors will get soldered integrated heat spreaders.

There is no guarantee that motherboards with chipsets older than the X570 can reliably handle the strict requirements for pci-e 4.0, tech marketing chief Robert Hallock reports on Reddit. “We can’t simply have a mix of ‘yes, no, maybe’ for older motherboards. The risk of confusion is too great.”

The hope among some was that PCI-e 4.0 would also come to motherboards with 300 and 400 Series chipset in the future, as they do support Ryzen 3000 processors. The main PCI-E 4.0 lanes, those for the video card and primary NVME drive, are controlled by the PCI-E controller integrated into the processor and not through the chipset.

In addition, according to Hexus, a Gen4 option appeared with the pci-e configuration of 300 and 400 motherboards after a recent bios update. This turned out to be an error that Hallock says will be corrected.

He also announced on Twitter that Ryzen 3000 processors, like previous generations, will have a soldered integrated heat spreader to have. AMD announced the third-generation Ryzen with 7nm Zen 2 cores produced at Computex last week. The processors will be available from July 7.
