Comment on Mirror seeing half the write IOPS on one disk than the other, is this normal?
themoonisacheese@sh.itjust.works 4 months agoI’m not fully familiar with the overheads associated with all things going on on a chipset, but it’s not unreasonable to think that this workload, plus whatever the chipset has to do (hardware management tasks mostly), as well as the CPU’s other tasks on similar interfaces that might saturate the IO die/controller, would influence this.
B350 isn’t a very fast chipset to begin with, and I’m willing to bet the CPU in such a motherboard isn’t exactly current-gen either. Are you sure you’re even running at PCIe 3.0 speeds too? There are 2.0 only CPUs available for AM4.

For sure.
It’s a Ryzen 9 5950X and I’m pretty proud how far I’ve managed to stretch this board. 😆
So given the CPU, it should be PCIe 3.0, but that doesn’t remove any of the queues/scheduling suspicions for the chipset.

Oh wow congrats, I’m currently in the struggle of stretching an ab350m to accept a 4600G and failing.
You’re right, you should hit PCIe 3 speeds and it’s weird, but the fact that the drives swap speeds depending on how they’re plugged in points to either drivers or the chipset.

On paper it should support it. I’m assuming it’s the ASRock AB350M. With a certain BIOS version of course.

It’s a gigabyte ab350m gaming-3 rev 1.0. it boots grub fine but then crashes right after displaying “loading Linux 6.x”, CPU led flashes then dram led stays on, I have to turn it off with the PSU switch.
Either it’s a rev 1.0 bug which is a thing on those motherboards, or the CPU (or igpu) is defective.

I’m currently waiting on support from both the seller and gigabyte but I don’t expect anything out of it, though I’m still yet to test it in a different motherboard.
