I'm running
AMD Ryzen 9 3950X Processor @4.315Gh with two Sabrent PCIE4 drives they benchmark at full speed.
I have the same setup running on a Formula Board too.
Yes, I too am looking to upgrade to those drives - it will be interesting to see what they do in RAID 0. My benchmarks:

QUOTE=njbongo;819502]Hi all,
I have a technical question about how PCIE 4 works on this board, and the x570 chips in general.
It is my understanding that the top M2 (M2-1) slot above the graphics card, and the slot the GPU goes into, share direct PCIE lanes to the CPU. While the bottom M2-2 slot has lanes going to the x570 chipset. At the moment, this is my configuration:
CPU - Ryzen 5 5600x
GPU - GTX 1070 (I just sold my 2080 ti for an obscene amount on eBay, and will be upgrading to a 6800XT OR 6900XT as soon as I can get one)
M2-1 - WD Black SN750 1TB PCIE3 NVME Drive
M2-2 - WD Black SN750 1TB PCIE3 NVME Drive
I was planning on upgrading BOTH drives to the new WD Black SN850 PCIE4 drives. However, if I do that NOW, with the GTX 1070 in there, will it force the drive in the top M2 Slot to also run at PCIE3 only? Or, are they still independent as to what speed they run at, even though they share lanes.
I did some searching and can't really find a clear answer, I'd love someone at ASUS to chime in and give me the CORRECT answer. 🙂
Thanks
