NVMe has been designed from the ground up, capitalizing on the low latency and parallelism of PCI Express SSDs, and fulfilling the parallelism of contemporary CPUs, platforms and applications. Such an interface has some inherent inefficiencies when applied to SSD devices, which behave much more like DRAM than like spinning media. This is because AHCI was developed back at the time when the purpose of a host bus adapter (HBA) in a system was to connect the CPU/memory subsystem with a much slower storage subsystem based on rotating magnetic media. While Advanced Host Controller Interface (AHCI) interface has the benefit of legacy software compatibility, it does not deliver optimal performance when an SSD is connected via PCI Express bus. Windows 8 already has native support for it. Probably only applies to sata 3gbps boards. System breaking betas, there are threads on the trouble that caused… Amd’s pretty bad with drivers to the point where they put out a beta gpu driver which for no good reason came with broken chipset drivers which broke peoples ahci sata driver setup, leading to failure to boot issues.
Amd sata controller driver update install#
Just a heads up for anyone facing the same problem.Įsp since the catalyst chipset driver package on amd’s site will install those drivers, so don’t take the shortcut, use chipset drivers from the motherboard makers site,and justs skip the sata drivers. This doesn’t apply to modern boards, they finally fixed it in later chipsets.

You think you are doing some good by installing windows and adding amd sata ahci drivers, but it only makes the performances abysmal, so just use the windows 7 default microsoft driver for best performance. Found out the hard way when upgrading an older amd system with a readycache. Seems they never fixed it for the 7xx and perhaps other southbridge amd chipset boards.
