The architecture allowed it. Sorry but there are lots of articles about this so dig in. And NO, there is no cure.

No...

If Vista SP1 is installed it will report the full 4GB, but only Vista x64 can use all 4GB due to the 32-bit limitations. As Bob said, there is no solution except to wipe the OS and install Vista x64 (using the same product key).

ok

how much am i actually using?
OS can use about

2 to 3.5 GB. Applications are limited to 2.0GB unless you set a special switch PLUS they are compiled with a special switch. IF you research this you figure out that going beyond 2.0GB has little payout for most.

well thats disheartening

one more thing out of curiosity why does windows 64bit allow you to have 124gig of ram. is such a thing even possible?
Be sure to dig into this one.

While 64 bit does that, the 2.0 GB per application is still there unless you get the 64bit version of the app. Is this an issue for you?
While I wish we had gone 64 in 2000 so all this was behind us it wasn't to be.
Bob
No, it doesn't...

(.5 Gb. or so) you get with 32-bit Vista is used to address graphics memory. That's why I only bought 3 Gb. of memory. If I was going to use 64-bit Vista, then the whole first 4 Gb. of memory is usable. But then you have to worry about getting drivers for hardware, and finding compatible apps.

How are you using on 3GB?
by Zeppo - 6/21/08 2:15 PM In reply to: No, it doesn't... by Doh_1Does your system run memory in dual channels?
If so, you should make certain your RAM is installed in pairs. Your combination of 3GB would take up 3 slots instead of 2 or 4. (You can't get 3GB into 2 slots.) This would mean your RAM is running in single channel, which slows it down by about half. You would be better off running 4GB, allowing hardware to use part of the 4th GB, thus still allowing dual channel capability, or dropping down to 2GB. If you run 4GB, you usually take a hit on clock speed (as well as hardware using part of the 4th GB) ie., 400mhz DDR drops to 333mhz.
In my AMD Athlon X2 system I got around that by purchasing CL2 Corsair fast RAM so I could manually set the clock speed back to 400mhz in the BIO, therefore, not taking a hit on speed. I don't mind hardware using the half GB.
So, if your system can run RAM in dual channel, your best bet is to run 2GB in 2 slots or 4GB of fast RAM in 4 slots. You don't want to run single channel unless you have no choice.
It's easy enough....
by Commandoclone87 - 6/24/08 7:47 AM In reply to: How are you using on 3GB? by Zeppoto run a pc with 3 Gb of mem as you can use two 1Gb sticks with two 512Mb sticks and that also allows the pc to run dual channel when the mem is inserted into the specified slots in your motherboard manual
No, less then 3.5GB
by Dango517 - 6/21/08 12:15 AM In reply to: does windows vista 32bit use all 4gigs of ram? by Rammstein420Some of the 3.5 is set aside for required programs by the OS these are hidden by the system so they don't show but are subtracted from the 3.5. In other words, they're there you just can't see them.

Addressing Memory
by msgale - 6/21/08 11:14 AM In reply to: No, less then 3.5GB by Dango517Guess what, DOS could not address all of the memory that the 8088 processor could, even if you had one megabyte of memory (I do mean megabyte). And the "missing" memory was used for amoung other things the screen buffer, which I believe was at 720896 or B0000.
No only 3gb, but seems sufficient - 17,340 3dMark06
by Ozzie - 6/21/08 5:52 PM In reply to: does windows vista 32bit use all 4gigs of ram? by Rammstein420Vista 32 addresses 3gb but I intall 4gb because I like matched pairs of overclocked RAM for no particular reason. Be careful however as some motherboards, even very expensive gaming ones, will not even boot with more than 3gb installed unless you are experinced in bios changes. Seriously, 3gb is a lot of memory especially if you get a graphics card with 1gb of dedicated memory.
