NVMe M.2 drive using chipset and disabling SATA

My buddy is running a Ryzen 3600, on an ASUS b450, with a 5700XT. His NVMe drive is disabling 2 out of 6 SATA ports. Logic says that the 3600 has 24 PCIe lanes, but for reason the NVMe drive seems to be using the lanes on the chipset instead. Please help.

16 lanes for GPU

4 lanes for NVMe

4 lanes for chipset

= 24

 

Make sure the NVMe is in the slot listed in the manual as the direct connection (usually the top one).

 

EDIT: it's also possible for SATA ports to come from the CPU with Ryzen and to be shared (electrically) with the NVMe (true on my Asus B350-F).

Yeah... We figured that out. Although doing that kicks the GPU to 8x. Doesn't seem to make a performance difference though.

Should not be a performance penalty for running that GPU at 8x. Ah limitations of our lesser boards. Well they need something for the X570 sales pitch I guess.. :P

It's so silly, cause like Abydos said, the CPU has plenty of lanes.

Yes it's silly they want to sell more expensive boards :P

For future reference check the mainboard manual before buying. Things like that are mentioned :)

In his defense, this is my old mobo that I had for my 2600 that he got for free.

Yes, it is silly to artificially kneecap a budget option to try to wrangle more money out of a customer that may not have the means. Better to build a product that you can sell at a good value and move more product. This will almost always lead to higher margins, because you're moving more units, and there's still plenty like me who are going to buy an x570 anyway for things like streaming, etc.

Wasn´t meant as a reprimand, more like I thought i´d through the info out there, in case other people stumble across it :)

Didn't take it as such. To be fair, the point is well made. I don't remember the last time I read the manual first. I decided I liked ASUS' bios over the others, became a fan boy and just picked chipsets from there out :P.
