ASRock A620M Pro RS WIFI motherboard supports PCI-E 5.0
Although AMD has limited the support of PCI-E 5.0 on the A620 motherboard to save costs for the board manufacturers and reduce the price gap between it and the B650 motherboard, there are always some board manufacturers who do not follow the rules. ASRock’s A620M Pro RS WIFI motherboard provides a PCI-E 5.0 M.2 slot.
Although ASRock officially stated that both the CPU-provided PCI-E slot and the M.2 interface of this motherboard only support PCI-E 4.0, wccftech has found that the M.2 slot of this motherboard actually supports PCI-E 5.0. They tested it using a Ryzen 5 7600 and the latest CFD Gaming PCI-E 5.0 SSD and the software recognized it as a PCI-E 5.0 x4 interface.
Furthermore, they used ATTO to test it, and the SSD did achieve a speed of 10GB/s, whereas the upper limit for PCI-E 4.0 x4 is 8GB/s. They contacted ASRock and confirmed that the A620 motherboard can indeed support PCI-E 5.0 SSD, and this motherboard has the hardware required for it. However, it is unknown whether AMD will completely prohibit the A620 motherboard from supporting PCI-E 5.0 in future AGESA updates, similar to what happened with the B450 and B350 motherboards’ support for PCI-E 4.0.
Nevertheless, considering the current prices of PCI-E 5.0 SSDs, providing support for PCI-E 5.0 on the A620 motherboard does not have much practical significance, as the cost of a single PCI-E 5.0 SSD could cover the price of an A620 motherboard and a Ryzen 5 7600 CPU.
