Unable to move pagefile to a flash drive nor enable ReadyBoost
Hello.
I need to increase my pagefile beyond the free size of my SSD disk (which is small in a laptop).
I need to perform some complex calculations (fitting some models with a lot of data in R) that need 400GB of RAM but my computer has only 16GB.
Then I had the idea of using a fast Sandisk 256GB USB to extend my pagefile.
But Windows Settings Virtual memory only allows me to select my internal drive. The USB doesn't appear listed there.
I've been googling and it seems that I first need to enable ReadyBoost, but that option is disabled because it says my main drive is faster.
The proposed solution I've found at many web sites is to find this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt
and inside a key with the name of my flash disk and change DeviceStatus to 2 and WriteSpeedKBs and SpeedReadKBs to a value larger than 1000.
But my regedit doesn't show that EMDMgmt key nor any WriteSpeedKBs and SpeedReadKBs keys either.
I have also tried to "flip" the removable media bit with tools such as Bootit, but it doesn't change anything.
How can I do it?
Thanks.
