Win Vista-64 ramdisk page file

I have 6 GB of ram and I am not running out of it. I want to prevent
windows from paging to my HDs. A while back I tried to simply disable
page file but lerned that no matter what windows will page somewhere.
I want to trick windows into paging onto a ram drive. I created a 1 GB
ram drive and placed page file there. I also turned off page files on
my HDs. After restarting the system, going to task manager I see
windows reporting that it has 2281MB / 13401MB allocated to page file.
and it reports 6GB of ram even though 1 GB is now a RAM drive. I am
not running out of ram, there is no need to page to HD, how do I
disable paging completely or force paging only to RAM drive?

Thanks ahead

How did you set up the RAM drive? If you have to run a program to create or
"allocate" the RAM drive from WITHIN Windows, then Vista has already set up
the page file elsewhere. So, you end up with two page files, as a minimum.

If you're serious about setting up a page file in RAM only, why not just buy
a solid state disk? You wouldn't need a large one. About 20GB would do.
The following 64GB model looks good:

For a page file, this would be about 30% faster than having the page file on
a regular hard drive. Write speed is about the same, so as information is
being paged, it will be just as fast. When the page is accessed though, it
will be much faster. That's why you'll only gain about a 30% speed
increase. This is the only way I can think of to actually force Windows to
give up the page file completely, or move it to RAM though. The page file
needs to exist on hardware, not software or firmware. The only thing that
makes this possible? Well, we now have hard drives made of RAM. :) -Dave

This guy, link above, will do 4GB ram drive, but its still at SATA
speed, limited to ddr1 and 4 GB. I have 2 GB on video card and 6 GB in
PC, soon might become 8 GB of ddr2-8500... Conclusion: For me paging
is pointless, I dont run that much memory intensive apps unless i run
number crunching apps i write in C. Can I anyhow eliminate my HD or
SSD from the picture completely, under windows vista-64bit?

I set up ram drive via windows hardware instalation and use driver
provided by RAMDisk_Evaluation_x64_530110.

I've moved the pagefile.sys before, IIRC, something about deleting it,
booting, then assigning new.

But don't take my word for it:
