well, because vista is 'smart' and it caches frequently used files from the HDD to the memory, but theres one stupid thing in it; it also throws processes that havent been used in a long while into the pagefile to make more room for caching... and this is something i dont want! i want ot have as much of the memory for the apps, as i have many apps that i use maybe once in 1-2hours, and in that time vista have put them in the page file so it can use 0.5-1.5gb for caching.. .. and its really annoying to wait for a 400mb app to come from page file back to memory just to check 1 thing that takes 2 seconds.!

and i think XP didnt do this, and therefore in xp my memory was used first, and the page file was used.. and therefore, i want to disable this caching to see if theres much difference.. ive been googling for a solution last 30 mins, but got nothing.. i already tried lowering the pagefile so it forced windows to use more ram as pagefile ran full, and my performance increased!! but the, thats not good as sometimes i do serious multitasking and need wayy too much memory so i have to have again a big paging file.. so well, SHORTLY: how do i turn off this caching?

Done

Murlocke

Press windows + R key, type services.msc and disable the following services

Windows Search
ReadyBoost
Superfetch

That should disable nearly all caching however you might see a performance loss without superfetch.

i disabled those long time ago with no difference whatsoever.. still full caching.. and this is really annoying especially in big games like crysis.. 1gb of my memory is cached, and crysis run 500mb on ram, and 1gb on paging file!!

Mine also runs 600~ cached, it says physical memory. Its caching it on your physical memory, not your page file.

Its normal.

It shows about 1200 if superfetch, readyboost, and windows search are enabled.


Page file is the kernal memory below that I believe, which says 210MB for me.

yes, i know it caches on physical memory AND NOW THATS THE PROBLEM here, it caches on the physical memory, causing low used apps go to page file! look.. ~1.7GB of page file is used, when ~1GB of it could be sitting on the memory for ~300-400x faster access time compared to HDD, like it did on xp..

I don't think the "Cached" thing in Task Manager is accurate.
I always have Superfetch and Readyboost turned off and yet it still uses the unused RAM to cache something.

well, it might be 10mb more or less or something.. but it is caching as it forces most apps to go to paging file so it can keep 50% of ram free for caching 'n stuff

Its caching the O/S. My system is caching double because it 64 bit.

Microx256

Its partially caching the parts of the os aswell as any other file used frequently, and i know it already, and 64bit dont make it double, in fact, there is no difference whatsoever because just clicking on a icon on desktop can cause it to use more or free more memory from cache so the difference cant be seen..
