Farhad,

we had a similar question, previously:Why can my 64-bit system only use 3.75 GB of RAM, when it has 4GB and should support 8 GB?.

Saikat had the perfect answer to that one. In short, dont worry, itsnormal and you most likely cant increase it any further.

However, I would be interested in learning what type of x youfound online to go from 2.53 GB, which is way too little usable RAMfor 4 GB installed, to 3.87 GB. This information may be helpful forothers.

Farhad2161I used http://www.tarfandestan.com/les/Patch-3-Windows-Vista-and-7.zip and it changed usable RAM from 2.53 GB to 3.87 GB.June 21, 2010

It does seem to be a glitch to have only 2.53 usable ram for 4 GBinstalled, and I am glad you have found a x, but I do agree with Tinathat you might have reached your maximum. Ram gets mapped bycertain programs and hardware as you boot you computer, so forexample, if you have a built in video card that used 256 mb of ram, itwill map and reserve that as you boot, so its very common for ramto show lower than the total amount installed.

Double check it again by click the Advanced options again. If youfound out that the Maximum memory reset to 0, then change it to4095.7. Restart your computer.December 23, 2011

Rakdo you have graphic card? if so, then the integrated Graphic and thegraphic card shared the memory together.. im also in 64bit OS. Justlike you said, DONT WORRY.. when it comes in running 64 bitapplication, the OS use all your RAM. The things that it shows theusable memory is that many application that running is 32 bit. Look atyour task manager, view the processes lots of x32.. December 23, 2011

how do i uninstall this patch?

MikeFrom what I saw in the command le this patch ads a custom bootentry with a customized kernel executable to Windows and selects itas the default boot option.

I would like to ask you to open up an elevated command prompt(right-click on Start > All Programs > Accessories > Commandprompt and select to run as administrator)

Type bcdedit in the command prompt and please reply back theoutput. With that I may be able to support you with the commands toremove the entry and uninstall the patch.

The only other way would be to repair the entire boot BCD via theWindows CD/DVD however in rare cases it doesnt work and resultsin a not bootable installation.January 11, 2012

FIDELISHello, as an alternative he can use Visual BCD Editor(freeware) tond out or get rid of new entry added by patch:

http://www.boyans.net/

He can also use EasyBCD, but it is paid software:

http://neosmart.net/EasyBCD/January 12, 2012

Anonymousperhaps like thisif you open system conguration (on run type mscong) then click onboot you have to see two boot options one is for the normal windowsand the other patch, perhaps you can delete from there. Also thepatched kernel le ntkrlICE.exe in the folder C:Windowssystem32
