Successful build - but NVMe performance potentially too low?

[anfas]

Hi all,

 

many thanks for this posting

 

solved immediately all my issues with this setup:

- ASUS H310 plus

- Gigabyte 6600Xt

- I9 CPU

 

All is fine - really. Only one thing. Did various benchmarks, all delivered results as expected. Only the storage seems to be too low. (I've seen results over 12.000)

I've chosen the EFI-configuration for Desktop Coffeelake.

ASUS mainboard settings are at (hopefully) recommended values.

 

Any idea/hint/pointer?

 

Thanks a lot in advance

Andreas

You have the NVME running in PCIe x2 PCIe 2.0 mode

 

 

That slows down the NVME a lot...

 

But your motherboard does not give for more, it puts it in the manual.

 

 

The maximum bandwidth of a PCIe X2 - 2.0 is little for a modern NVMe

 

In that port you have 500MB/s per lane... since they are two lanes, it gives you 1000MB/s. and you are not very far on the bench that you show

Ok,

thanks a lot for the quick reply.

understood - works as designed.

 

In that case I've to look for a mainboard with higher throughput.

 

Best regards

If you don't make intensive use of copying files, don't change the motherboard, those simple boards work great on MacOS and are very easy to configure for the apple system

 

I've tried many motherboards this simple and they're all rock solid on MacOS. 👌

 

And at almost 1000MB/s in normal use you won't notice much of a difference to faster drives. 

 

Could you look in the bios if there is an option to put the M.2 port in PCIe 3.0?  if you could you would double performance on the NVMe
