Let me get this straight.
with default bios options my samsung 960 evo runs at maximum speeds.
Read 3198(3200)mb/s - Write 1890(1900)mb/s. Its a pci-e gen3 x4 ssd.
all those on an asus prime z270-A with i7 7700k.
When i overclock my cpu the ssd write and read speeds drop.
No matter what my overclock is from 4.5ghz to 4.9ghz(max stable i used) the speeds are the same
Read 2290mb/s - Write 1609mb/s.
Never heard of it before but i want to know does my cpu overclock affects my pci-e ssd speeds?
The pci-e speed is left on auto(100 by default) and blck is also on auto (also 100 by default).

Let me clarify this for you.
With the standard BIOS settings, my Samsung 960 EVO runs at full capacity.
It achieves 3198(3200)mb/s read and 1890(1900)mb/s write.
It's a PCI-E Gen3 X4 SSD.
On an ASUS Prime Z270-A with an i7 7700K, overclocking the CPU causes SSD read and write speeds to decrease.
Whether I overclock between 4.5GHz and 4.9GHz (maximum stable), the speeds remain consistent.
It reads 2290mb/s and writes 1609mb/s.
I'm not familiar with this model but I'm curious if my CPU overclocking impacts the PCI-E SSD performance.
The PCI-E speed stays on auto (100 by default) and the block is also auto (100 by default).
The manufacturers design it to revert automatically... though that doesn't always work well. At least based on my experience, across various boards I've seen...

The manufacturers design it to compensate, though it doesn't always work perfectly. From my experience, on various boards I've tried with a M.2 Samsung 950 Pro, increasing the BCLK leads to a decline in drive performance.
