Supported Memory Size – Windows Vista and Windows XP

Ad

Regardless of which version of Windows you are using, all 32 bit systems are limited to a maximum of 4 GB of RAM. The only exceptions to this rule are the Starter Editions, which are primarily targeted at developing nations.

There is only a single 64 bit version of Windows XP which is identical in feature set with Windows XP Professional. From a technical perspective, it is built around the Windows 2003 Server kernel (Version 5.2) though.

I've been using 8GB with Vista for a while now. I can play Crysis or CoD4 whilst simultaeneoulsy video encoding in the background without a single stutter... very smooth. Well worth the money IMHO.

There should be a bench marks showing how big a performance increase you get as opposed to 1gb, 2gb and 4gb. Sure it might be cheap to do, but is it worth the hassle of spending the money, waiting for the order, installing the ram and doing the necessary tweaks?
I like the charts on the max supported ram per OS, but you need to show the user why they may need 8gb of ram, instead of "because you can" being the reason.

I agree with joedastuff, what I'd like to know is why getting 8GB is worth it when compared to 4GB, not 2GB or less. 4GB has been proclaimed the "sweet spot" for Vista a while ago, so why would we go for the extra 4GB, especially considering we'll have to re-spend our money on DDR3 if we decide to upgrade a year or two from now?

tsebbens' comment is pretty encouraging though. Encoding and gaming are two things I do quite often. But the fact that you can do both at the same time really a consequence of the 8GB or RAM or is it due to the processor (I'm guessing it's a quad?)?

Hello, I'm new to the forum but have read articles on this board for years.

My question is, where does readyboost fit in. I have vista home premium 32bit with a Q6600, and a 2 GB USB for ready boost. About to swap it with a 4 GB readyboost stick, will an 8 GB USB make a difference??

there be no speed boost haveing more ram

what more ram does is prevent Slow downs due to running low on ram so pageing happens

allso one other Point that is an small error about going past 4gb on an 32bit program it cant happen
if it gets correted an 32Bit program can only allocate 4gb of VM space even with 8gb of ram No page file would be used at all as the program can only use 4gb of space (in games i have only seen this happen on Supreme commander when there is an High amount of units on the map can use quite alot of ram or allacate alot of Vm space taht can be fixed by patching the game.exe file to make it support Large mode so it can use upto 4gb {default is norm only 2gb})

readyboost sucks once you got more then 1gb of ram (2gb installed or more) as it does nothing to speed things up as ram is faster then Flash and allways will be the Readyboost can give slower performace

as an test on my pc readyboost makes my games judder when ever the flash drive is accessed
