Memory Increase for Vista Ultimate 64-bit?

[Guest Jim]

The maximum memory one could have in Windows XP x64 was 4 GB per CPU.

In Vista Ultimate you can have 128 GB total. (I still have the same 2

CPUs and 8 GB of memory.)

 

Is there any advantage to add 8 more GB of memory to the 8 GB I

already have to make a total of 16 GB? I have a Tyan motherboard

which can accept up to 8, 2 GB DIMMs. I currently have 8 GB, so I

could add 4 more DIMMs.

 

I do not want to waste money, as I really want a new monitor, but I am

interested in the possibility of adding more memory if Windows would

really take advantage of it.

 

Thank you!

This depends _entirely_ on what kind of work you're doing and how your

computer is running. Windows can always use RAM - if it has no other use for

it, it will use it to increase your cache, keeping more things quickly

available in RAM instead of having to get them from your hard disk. But,

that being said, very few "knowledge workers" or others running typical

business tasks use or need more than 8 GB right now. OTOH, if you're doing

heavy graphics editing, or other memory intensive processes, you could

easily use more. If you're running VMs, you will use more.

 

Take a look at your running memory usage during a typical period. If it is

close to the actual available memory, then it's time to add more.

Really?

This seems to imply (or rather, directly state) that 64-bit Windows XP

can use 128GB.

The maximum was (and is) 128 GB. OTOH, boards created at that point often

couldn't handle any where near that. So some mobo mfg's never managed to

update their BIOS to handle the really large memory configurations.

Hi Charlie,

 

I was hoping you would see my question and respond to it. Thank you!

 

I do not think I do anything which would require that much memory. I

just thought that, if Windows Vista itself was particularly "hungry"

for memory, I could give it more.

 

I think I am better off putting my money toward an HDCP compliant

monitor.

 

Thanks again! :-)
