I'd like to know if it is possible to increase the DMI bandwidth on a P55 board (ASUS P7P55D-E) by increasing the BCLK.
The reason for this is my plan to use an m2 NVMe SSD in my second PCI-e x16 slot (only 4 PCI-e 2.0 lanes available) with an m2 to PCI-e adapter.
Now, the problem with the P55 chipset seems to be that it bottlenecks itself hard with a DMI bandwidth of only 2.0 GB/s. That appears to be the reason why the PCI-e 2.0 lanes only operate at 2.5 GT/s (PCI-e 1.x speed).
With everything left at stock that would probably slow down a modern SSD to 1000/1000 MB/s read/write.
Would the DMI bandwidth increase with a higher BCLK or is it independent?
Could that improve the read/write speed of the SSD?
Is all of this bullshit? If yes, please feel free to enlighten me
