Welcome to the home of 7-max!
7-max is a program for accelerating your Windows system.
It increases the performance of some applications up to 10-20%.
7-max is a free software distributed under the GNU Lesser General Public License.
WARNING: 7-max can be unstable for some systems and it can hang
your Windows. So it's better to close other programs
before first start of 7-max. If you have important data
on your hard disk, it's better to backup them to some medium.
And read FAQ for more information about possible troubles.
If you are not ready to take risks, just don't install 7-max and
don't use it.
Windows XP x64

Frequently Asked Questions (FAQ)
How to make 7-max work on Vista?
Open "Control Panel / User Accounts / User Accounts / Turn User Account Control on or off"
and disable "Use UAC" option. Then you can use "7-max".
How does 7-max work?
Windows uses small (4 KB) RAM pages by default. If you run any application with 7-max,
that application will use large (2/4 MB) RAM pages. Large RAM pages provide increasing
7-max can speed up applications that use big amount of memory. In our tests,
7-max gives 10%-20% speed improvements on modern file compression programs
like 7-Zip (www.7-zip.org).
The biggest improvement can be obtained in CPUs with small L2 Cache: Celeron, Sempron.
All modern CPUs (Core, Core 2, Pentium 3/4/M/D, Celeron, Athlon XP/64/FX, Turion, Sempron, Duron ...)
support small (4 Kbytes) and large (2/4 Mbytes) RAM pages.
But Windows by default uses only small pages.
It's much simpler for CPU to handle large (2/4 MB) pages than
big number of small (4 KB) pages. So programs that use large pages
work faster than programs using small pages.
If you run some application with 7-max,
7-max modifies memory allocation calls to allow application to use large pages,
and it's possible that application will work faster.
Why doesn't 7-max 5.00 work on my computer?
7-max 5.00 works only in Windows 2003 / XP x64 / Vista.
If you use Windows 2000 or Windows XP 32-bit, you can try 7-max 4.01, but
7-max 4.01 is very unstable in some systems and it can hang or crash your system.
7-max 5.00 is more stable than 7-max 4.01.
Why doesn't 7-max 4.01 work on my computer?
If you use Windows XP, install Windows XP Service Pack 2. It fixes some problems.
7-max 4.01 works only in special system mode.
So 7-max 4.01 changes boot.ini file. The boot.ini file is a
text file that stores
boot options for computers running Windows operating systems. When the
computer starts, the operating system loader reads the boot.ini file and
displays the entries for each operating system in the boot menu.
7-max 4.01 creates new item in boot.ini file with special switches.
7-max 4.01 doesn't change original entry in boot.ini, so at rebooting
you can select which mode do you want: original mode or 7-max mode.
The most problem switch is /3GB. Some computers can't boot with that switch.
We suppose that it's because of incorrect hardware drivers.
So, if you can't boot in 7-max mode and still want to use 7-max,
you can try to find and solve the problem. At first, you must install new instance
of system (Windows 2000 or XP) to some other drive. Then install 7-max
before installing your hardware drivers. Then if your computer can boot
in 7-max mode with new system, you can try to install your hardware drivers
by one at a time, and reboot after each driver installing. So you can find driver that doesn't work
in 7-max mode. If you find such driver, you can try to find new
version of that driver from hardware vendor and report them about incompatibility
with /3GB switch in boot.ini file.
7-max 4.01 also can't work with Windows XP SP2 installed in some modern CPUs
that support NoExecute feature. In that case Windows enables PAE mode. 7-max can't work
in PAE mode. To disable PAE mode you must add switch /noexecute=alwaysoff to boot.ini.
How to uninstall 7-max 4.01?
Before uninstalling 7-max 4.01 you must remove 7-max items in Tools / Boot options.
Or you can edit boot.ini file in text editor, if you understand commands of that file.
We compared the speed of compressing of two modern
file compression programs:7-Zip 4.29
and WinRAR 3.50 running in normal system, and running under 7-max.
We used benchmark tests that are built into these programs.
7-Zip was tested with 8 MB dictionary in multi-threading mode.
Computer configuration: Athlon 64 X2 3800+, 2 GB of RAM, Windows XP x64.
