not having a problem is not what we are saying.Im runnin 64bit on a HP Slimline with 4gigs ram i have no problems i did have a gateway laptop runnin 32bit and never had a problem also
Exactly, I mean, it will use the 3 gigs so that is great rather than 2 gigs, but too bad you have to wast the last gig.not having a problem is not what we are saying.
My professor just ordered some dell laptops with XP pro downgrades on them, and it has 4gig installed, but only 3gig is recognized. sure it isn't a "problem" but its kinda a waste to have ram just sitting there
32-bit Windows applications have a 2 GB address limit. If you use a truly 64-bit application, it should be able to use more than 2 GB.Picture should be flipped upside down though, it starts with the highest address, which is the "bottom" of memory.
OS/Kernel takes the top.
something else very interesting is the 64 bit os's can address alot more memory, but the OS ensures that it is only allocated in blocks that can be addressed in 32bit registers, in case truncation occurs.
I just finished a research project on this for my Operating systems class.
here is an excerpt from my presentation notes
Virtual Memory
XP Pro uses 4kb pages
32Bit systems limited to 4GB virtual address space
2GB User Applications
2GB System Applications
All memory onboard is included, even video card.
64bit systems can address up to 8 terabytes of space
Although 8TB of space is addressable, the system insures that every memory allocation is under 2GB

64 Bit Virtual Memory Issues
Pointers are 64 bit, but the system will only allow up to 2GB because if a 64 bit pointer is truncated at 32bits the data is not lost
64 Bit XP main memory published limit is 128GB, although some packaging states 16GB is the limit and some users state problems with more than 16gb main memory
Matlab and Mathematica have 64-bit versions, there are a fair amount of 64-bit apps.32-bit Windows applications have a 2 GB address limit. If you use a truly 64-bit application, it should be able to use more than 2 GB.
Of course, finding a true 64-bit app is pretty difficult. Only one that I'm aware of is Adobe's CS4.
I've noticed that the score seems to to coincide with your lowest rating. Eg. If your lowest rating is video capability, (5.0) then your Vista score would be 5.0. Your best bet in this case is to get a better vidya card. 8800's are cheap right now. Found one for $75 the other day.I cant figure the dam thing out........It says I am 4.8 rating,but I need more ramso I go to the store and order up some ram,now I have 6gigs of ram and my score is exactly the same.........
I could use some help here as i am 5.7 or higher on every other catagory except ram
and I have plenty of ram
You do realize that it says that your score is determined by your lowest subscore right below your rating right?I've noticed that the score seems to to coincide with your lowest rating. Eg.

Yes.You do realize that it says that your score is determined by your lowest subscore right below your rating right?
