Short freezes when having both NVME SSD and nVidia NVS 300
Solution 1:
I have yet to confirm that, but the problem seams that I ask too much of the NVIDIA NVS 300. It is PCIe Gen 1 which is already relatively slow, but putting it in a x8 slot (there is no option in bios to configure it to x16) makes it struggle with two monitors. Interestingly enough GT9600 which is PCIe Gen 2 still has this problem. Moving to GTX 550 TI fixed the problem. Or at least I haven't noticed any freezes for the last 3-4 hours. I'll come back in a few days to report.
I guess Google Chrome uses a lot more graphic power than I thought.
Update. Confirmed - Installing better graphic card fixes the problem. I have no idea why this problem happens. Could be related to NVME being on PCIe and running different revisions of PCIe SSD on PCIe 3.0 and video on PCI 1/2. It's strane that both GT9600 and GTX550 run on PCIe Gen 2 but only GTX550 runs smoothly. Also I never noticed GT9600 causing freezs on older machine with SATA disk.
