PCIE3x4 should be fine, but will work as x2.
if you have 2666MHz version, then install 2666MHz, but 8GB per slot is maximum.
For now i have 1TB HDD , i want to replace also in SSD and I want to additional m.2 Nvme? But im now sure if supported? And for ram can i upgrade up to 16gb? What i need RAM?
Yes, there is a M.2 2280 slot on this model, supporting PCIe3x2 NVMe SSD.
We only test the largest capacity to 512GB.
And for RAM, the original RAM is onboard. There is an extra slot supporting DDR4 2400MHz RAM up to 8GB.
