Changing Registry to use 64 bit WIndows better


T

Turtle

Hi everyone,

I have a Windows 7 64 bit Version with 6 GB RAM.
In a PC Magazine I read if one has more than 2 GB RAM one can change the
registry to use this memory better.

REGEDIT:

HKEY__LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
Session Manager\Memory Management

Double click DisablePagingExecutive and change Value from 0 to 1.

Change LargeSystemCache Value from 0 to 1.

This should come into effect after booting new.

Windows loads in the memory and not on the Hard disk.

Does anybody agree or disagree with this?
Does it matter whether one has the Windows 7 64 bit Version or the 32
bit version?

Thanks in advance for your help.

To what end? Do you have a link to the article?

Leave it as it is!

How do these particular tweaks affect the pagefile?
The tweak disables it. Everything is run in main memory.
This will speed up some operations but the machine will crash
should you ever try to use more ram than you have physically
installed. Running several large programs at once or editing a
large image could easily require more RAM than you have.
With a pagefile the only thing you'll notice is that there are
slight delays occasionally.
I have 24 GB physical RAM and I wouldn't disable mine.

Thank you. That's all I wanted to know. I don't tweak the system
defaults without a very good reason.

Good decision, cos Windows only allocates stuff in your page file, if
needed.
"Windows 7 includes a file caching mechanism called SuperFetch that caches
the most frequently accessed application files in RAM so your applications
will open more quickly. It's one of the many reasons why Windows 7 feels so
much more "snappy" than previous versions-and disabling the pagefile takes
away RAM that Windows could be using for caching. Note: SuperFetch was
actually introduced in Windows Vista."

Hi everybody,

Thanks for all your answers.

I wanted to get a 2nd opinion before tweaking the system
defaults.


Tell me, does it make any sense to to set up a RAM Drive?

Some people put their page files on a RAM Disk.

I dont know if this brings anything for my Windows 7 64 bit Version with
6 GB RAM.

Thanks in advance for your help.

The best advice is don't do it unless you, personally, understand
exactly what you are doing and why and how to undo it if your computer goes
south. You have to ask yourself, if this simple tweak is so wonderful,
why isn't it that way in the first place? Does Microsoft deliberately
make its system less than optimum so that all the self proclaimed gurus
have something to write about in their blogs? Nobody understands Windows
better than the people who wrote it.

That is interesting since the recommended size for a pagefile is 1 1/2
times the installed RAM. The whole point of the pagefile is to free up
RAM space by providing extra cache space on the disk for "old" data.

No.

Maybe some people do, but it's a very foolish thing to do. The page
file is used when there isn't enough RAM--it uses disk space instead
of RAM. Using a RAM Disk for the page file is using RAM instead of the
disk that is used instead of RAM. Moving stuff from RAM to disk to RAM
accomplishes nothing, but costs you performance because it introduces
extra overhead for no reason.

Not to mention that some of the application RAM you might be filling up has
been set aside to make a RAM disk, thus diminishing the amount of RAM
available for programs, and thereby also requiring increased use of the
page file.

Sort of becomes a dragon eating its tail. Or an auto-immune disease. Anyone
care to offer further metaphors? :)

Yep. Thanks for the addition.

Except they're not really metaphors; more like idioms.

Thanks, I'm happy to take idioms if I can't get metaphors :)

Aristotle says trying to cure a morally weak-willed person by telling
them they are doing something wrong is like trying to help someone
choking on water by washing it down with water. (Nic. Ethics. 1146a34-36)

curing a limited ram problem by laying aside some of the ram.

sorry, best I could do right now.

hey, you wanted a metaphor!

Hi, Gene.

Reminds me of the story my Dad used to tell me about the old Indian (We're
Choctaws.) who cut off one end of his blanket and sewed it onto the other
end to make it longer.

Heck, anytime I can get help that includes Aristotle, I'm *way* ahead of

One time a number of years ago, during one of the times time when Daylight
Saving Time was being extended because of a fuel crisis, Oliphant published
a great cartoon, showing someone doing just that. Now I know where he got
it - thanks!

I pretty much hate DST, which is one reason I liked that cartoon and will
never forget it :)
