Windows 7: Pagefile always reverts to default on C drive

Windows 7 Home Premium 64 bit
Pagefile always reverts to default on C drive

I went into the settings to change the pagefile location & size. I am aware how to navigate into that location and change the setting.
I have a drive P: called PAGE specifically for that.
I have 32 GB memory and the P: drive 60 GB in size.
I change the settings to that drive and specify 48000 MB size. I make sure the "automatically manage page file sizes for all drives is unchecked. I set the C: drive to none, clicking the "set' button after each change.

I reboot the machine and it seems to be as expected.
When I reboot again the Pagefile is always back on the C drive.
When I go back into the Virtual memory box the 'Automatically manage paging file size for all drives' is checked again even though I specifically unchecked it.

It is important for space & performance I use the P: drive.

I do I make sure the machine always uses it and does not revert back to default.
As far as I am aware there is nothing physically wrong with and drive.

I am using windows 7 64 bit professional.

It is extremely frustrating.

It is best to have the Page File on the C drive, which gives the best speed & performance, but looking at your System Specs you show that you have 3 x 60Gb SSDs, so I can see why you are trying to change the Page File to one other than the C drive. In practice a 60Gb drive is far too small for Windows as your main drive. A 250Gb SSD would be a much better choice & you could easily run the Page File on it as well.

Also your Specs show you are running Windows Home Premium & your Specs show 16GB of RAM being used. You state in your Post that you have 32Gb of RAM installed, if so, you are wasting 16Gb as Windows Home Premium will only support 16Gb of RAM.

Windows 7 Home Premium 64 bit

I have a licence for both home premium and windows professional. I am presently using windows professional. Home premium is no use to me as it cannot do striped dynamic disks. I am fully aware home premium cannot use more than 16GB which is why I no longer use it.

I am not in a position to do any hardware upgrades.

It is an older machine. I have good reason to not have the page file on the C drive. Firstly I use caching software using memory to cache the boot SSD. Windows caching does not do a good enough job.
My boot drive is a 120 GB ssd cached with some memory to cache using primocache. It improves performance a lot. It is important the PAGE FILE IS NOT ON THAT DRIVE.
I have 3 x 60 SSDs in a striped drive. This is for the swap file and onther partition for caching. Read speeds are 1.2 GB/s. A single SSD is not fast enough.

I need the SWAP file on the second drive and for performance is needs to be around 1.5 the memory size. This has been recommended to me by another party and verified.

So the 60 GB P: drive I setup with those 3 SSDs I need to use for the pagefile.
It is not possible to install NVMe SSDs on my machine.
How exactly do I do this and make sure it stays there.

"Advanced" > "Startup and Recovery" > "Settings"

"System failure" >"Write debugging information" > change drop down menu to "None".

Alternatively, move the pagefile as you have already done and also set a custom size of 2gb on your C drive for dumps.

I cannot have the pagefile on the C: drive as explained already.

I changed the debugging information option to none. It makes no difference.

I set the information to the drive & size I want about 48000MB. There is ample space for that size.
Exactly the same thing happens.
I reboot once, the pagefile is still on my P: drive but the 'Automatically manage paging file size for all drives is checked even though previously unchecked it end applied the changes and the pagefile is on the C: drive.

Why is it not working?

This is extremely frustrating.

Not at all, it greatly depends on the disk configurations of the computer. Best speed is achieved by having page file(s) on the fastest drive, which is usually C, but not always. And if you have two equal drives being the fastest, it's even better to put Windows on one and the page file on the other.
As long as we're speaking about physical drives. Partition don't matter at all about performance, and only affect free space management.

Is the P: drive a regular SATA (HDD or SSD) drive or it is a USB flash drive?
