Rizonesoft Memory Booster
Rizonesoft
Before you think “not another memory booster/optimizer”, Rizonesoft Memory Booster is not just another memory-booster. And yes, I know that many software companies claim that they have the solution to never upgrading memory again. First of all, most of these companies are full of it, most of them rely on the placebo effect, this is, if you think it is going to work, it will. Also, most of them will try and optimize your system by forcing memory out of RAM. Rizonesoft Memory Booster does not run on the placebo memory optimization engine and will not force any memory out of your RAM. It will, however, make a safe Windows API call that tells Windows to clean up the workspace of all processes thus freeing up any memory, processes no longer need (clear processes working set). It will do this periodically to help improve the speed and the stability of your system. Keep in mind that this method will not free up a big amount of RAM, but it will improve the stability of your computer.Starting Price: Free -

MemOptimizer
CapturePointStone
The Problem: Almost 100% of software programs contain "memory leaks". Over time these leaks cause less and less memory to be available on your PC. Whenever a Windows based program is running, it's consuming memory resources - unfortunately many Windows programs do not "clean up" after themselves and often leave valuable memory "locked", preventing other programs from taking advantage of it and slowing your computer's performance! In addition, memory is often locked in pages so if your program needed 100 bytes of memory, it's actually locking up 2,048 bytes (a page of memory)! Until now, The only way to free up this "locked" memory was to reboot your computer. Not anymore, with MemOptimizer™! MemOptimizer frees memory from the in-memory cache that accumulates with every file or application read from hard-disk.Starting Price: $14.99 one-time payment -

Memory Cleaner
Koshy John
Tech-savvy folk are divided over how useful memory cleaning tools can be because Windows (Vista upwards at least) manage memory reasonably well. Most memory cleaning tools are not very useful because many of them use ill-advised techniques that are only relevant to older versions of Windows (pre-Vista). Memory Cleaner is considerably better because it uses functions built into Windows to judiciously free memory - with no performance impact whatsoever. You can now access Memory Cleaner functions from the tray icon without having to open up the main window. The cleaning procedures are both silent and the only alert you will see is the amount of RAM recovered briefly displayed in the window.Starting Price: Free -

Minimem
Kerkia
Initially developed for Firefox only, Minimem now can reduce the memory footprint of any application. It runs in the background and can be set up to optimize as many processes as you'd like, using a very intuitive graphical interface. Unlike other memory optimization products, it gives you full control over what applications you want to optimize, when and how often, as well as the possibility to only optimize memory when required and relevant. It optimizes memory by removing as many non-necessary memory pages as possible from the selected processes. It does so at regular intervals which can be user-defined as well and every 30s by default, though uses an advanced pooling mechanism to ensure the CPU usage of Minimem remains low at all times. This then optimizes your applications which can load those pages back whenever they need, and makes your overall system perform much better whenever it is memory limited.Starting Price: Free -
