Já jedu na 2x4gb, gtx 970 a nic takového nezaznamenávám. Zkuste pogooglit, třeba je na to fix.

//tak jsem to udělal za tebe - nastav si page file ve windowsech

Open file explorer.
Right-click on This PC and click properties.
On the left hand side of the window, click advanced system settings.
Click Settings under the performance tab.
Click on advanced and under virtual memory click change.
Make sure Automatically manage paging file size for all drives is unticked
Lastly, hover over your hard drive. (If you have a spare SSD I highly recommend you ensure your page file is only on the SSD.) Now make sure custom size is set, and at the bottom of the window there should be a tab named Recommended. Change the initial value to what the recommended value is, as well as the maximum value.
Lastly, hit Set then Ok and Finally Apply
