Don't believe everything you read on that page. Information on it seems like it's been copied from assorted sources, and poorly, at best.

Like, slow boot time is a sign that you need more memory... I have 6 GB of ram, DDR2 800 MHz, and Vista (x64) boots for 2-4 minutes. In this case this is (known) bug in Vista, if you have more than 2 GB of ram chances are that you'll have this long boot time. It seems it's an issue with Vista and motherboard BIOS/BIOS settings. In some cases after BIOS update it boots normaly. If I take 4 GB out it boots under 1 minute. Once it boots everything works normal.

Then that task manager part, amount of ram in it is not in kilobytes, it's in megabytes, and it's not 2045 for 2 GB, it's 2048 MB. Also about that ram caching feature (superfetch). When you boot up vista, hard drive will work constantly until all free memory is cached, i.e. vista will try to predict what programs you'll going to run and preload them in memory. This could be good if it's guess is right, but if it's not, it's useless. Not to mention that it could take a while to fill all memory if you have bigger amounts of ram. Luckily, you can turn Superfetch process off.

Then, in next paragraph, 72 pin simm ram was old 10 years ago EDO and FPM memory was packed in 72 pin simm modules, FPM was mostly used in 486 computers, and EDO in 486 and first pentiums. So why does he advise to "Therefore bite the bullet, order that 72-pin RAM SIMM..." is beyond me.

Next, readyboost is not a way to add more ram to your PC, it's an addon to swap file. Swap file is normaly used by windows, regardless of how much memory you have. Some "stuff" that goes in it is big, and some is small. Since swap file is on hard drive, it's seek time is much lower than ram (ms vs ns), even USB stick memory has faster latency then hard drive. Here's where readyboost comes in, if you connect USB stick to your PC and enable it for readyboost, vista will cache smaller files on this USB stick. They will also be in swap file, so if USB stick malfunctions, or is disconnected while computer is on nothing will crash, it will just revert to swap file instead of USB stick for those files. In real world, applications will start few seconds faster if it's enabled, maybe...

When I look at it again, don't believe anything you read on that page :). I don't know why they state so much useless (and wrong) stuff, only memory advice for normal vista work should be 1 GB minimum, 2 GB recommended, more if you use applications that can use more than 2 GB ram and of course 64bit version of vista. If you have 4 or more GB of ram on 32 bit vista it won't recognize more than 3.25GB of ram. That's the limitation of 32bit OS, nothing windows related.
