Windows 10: 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.

Enabling Windows ReadyBoost on a flash-based drive Tablet PC

Hi Cesar,

If your system has a flash-based drive such as an SSD hard disk in it, using ReadyBoost isn't necessary. You will receive the message, "ReadyBoost is not enabled on this computer, because the system disk is fast enough that ReadyBoost is unlikely to provide
any additional benefit." This is because a system with an SSD hard disk, along with SuperFetch, can outperform ReadyBoost.

If you feel that your device's performance will improve by enabling ReadyBoost, we request that you take a moment to send us your suggestions through the
Feedback Hub which is readily available with Windows 10. You can find it through
Cortana or the Search bar.

If you need further assistance, let us know.

 

The readyboost tab is missing but is enabled in services.why?

Hi,

Device compatibility is one of the reasons why the ReadyBoost tab is missing. Kindly provide the following answers to the questions below to further isolate the issue:

• What is the make and model of the flash drive that you are using for ReadyBoost?
• Have you tried inserting the flash drive to another USB port?

In the meantime, we suggest updating the driver for your USB drive. This will help us identify if the issue is caused by outdated drivers. Kindly follow the steps on this article to update it:
Update drivers in Windows 10.

We recommend using our
Bing Translator to translate this message into Slovenish.

We'll wait for your response.

 

Readyboost

Hi,

Thank you for posting your query in Microsoft Community.

I will assist you with this.

ReadyBoost can speed up your computer by using storage space on most USB flash drives and flash memory cards.

ReadyBoost uses the Superfetch service that should be enabled and set to "Running" and "Automatic".

For ReadyBoost to effectively speed up your computer, the flash drive or memory card should have at least 1 gigabyte (GB) of available space. If your drive or card doesn't have enough available space for ReadyBoost , you'll see a message telling you to free
some space on it. For best results, use a flash drive or flash memory card with at least double the amount of available space as the amount of memory (RAM) in your computer.

I would suggest you to try the following steps and check if it helps.

1. Plug the flash drive into a USB port on your computer.

2. In the AutoPlay dialog box, choose Speed Up My System.

3. The flash drive’s Properties dialog box appears with the
ReadyBoost tab upfront.

4. Click on ReadyBoost tab.

5. Choose the Use This Device option.

6. Click OK.

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.
