Windows 7: More RAM doesn't always amount to better performance

It's sitting there in your computer but can't be used because Windows does not have enough memory addresses to map it. There are other devices in the computer that also have memory address space set aside for them. The total address space dedicated to hardware is unavailable to the OS. That's why a system with four gigs of ram can only use 3+ gigs. I hope this is more clear. The only way to resolve this is to switch to a 64 OS - it can address a much larger amount of ram.
Got it... hope to get 64bit OS once its officially released... just hope it'll run with my software...

And thanx for your help... much appreciated...

Wow you guys are really into it. Your all right. When i was an IT mgr overseeing a performance group in a large 360/370 installation the thing we always looked at was the amount of paging or thrashing done by our DASD (disks), multiple reads done to your paging drive will bring any system to its knees. You really want to keep as much of the application as possible resident in memory. Ideally to have the entire app in memory is ideal but will never happen. So when Jimbo says buy faster drives hes absolutly right but when you compare milli sec (disk access times)to micro sec (memory access times) ther isnt a drive out ther that compete with memory. Fake is right on when hes says "If you have a crappy hard disk, disable your page file, buy 4 gigs of ram and run completely off ram, this will stop page faults (swapping of memory to the hard drive and vice versa) which is a huge performance gainer.." or configure a raid drive and use 2 drives in tandem. Enought has not been said about performance in a PC. For instance nothing has been mentioned about tuning your memory to your FEB that your MB is capable of handling. that boosted my rating up .2 points. I'm, currently running 6 gig an do a mixture of video and gaming. Im satisfied with my performance but its not only the amount of memory, the speed of your drives, the speed of your cpu, or the speed of your front end bus. It's the way you bring all these components together in a harmonous way using each to augment the other. Thats why i still build my own system when i need another. I really wonder about dell and hp and the rest of these manufacturs bout the time they spend really tuning their systems. I haven't seen a good "store bought" system. But thats another topic. For now I'll enjoy the snappiness of 7232. LOL

LOL never heard that term craptop. I have one of those too.can only get it up to 1.5 gig but win 7 does very nicely. I realy think this is the best MS has ever done. Hope they get the credit they deserve. MSE is looking good too. Steve is doing a great job.

No!!! your page file is one of those things you really need unless you have loads of memory like 12 gig. I have 6 gig and my paging is set to win 7 default

I'm not that smart, but i suspect it is a percentage of your available HD Capacity. and by using the default value set by MS using some algorithm i feel comfortable that its pretty reasonable. if you have another HD try spreading your paging files over 2 or even 3 drives. if you have several windows open it may let your apps run faster.

2 GB ram here and i need more.
Firefox 3 (3.5 Also) goes and eats like 1.4 Gb ram for me and i bet it can eat more but it can't anymore as other resources are taken by system and other processes.

So yeah more RAM is needed
