4gb over kill? - Page 2

post #11 of 30
I used 4gb and 2gb on vista, in that order, and it was like going back to 512mb of ram in XP. There is such a big difference that it doesnt make sense. After having to drop to 2gb, I immediately sold off the ram I had, and bought 4gb again, even with taking a small loss. For me there is no question. All I do is play some games, and fold. It was so incredibly slow I couldnt stand it. Go 4gb, especially if you're running Ultimate. You wont regret it. Plus, its not that expensive for 4gb.

**edit: Oh, and with 4gb, vista will use more of that to preload into memory programs that you use. It uses quite a bit now, but at idle, running just firefox, im using ~2.2gb of memory.

For me, Windows uses 2.640gb and thats all it can see. If I got a 1gb stick to add to it Windows could not see 200mb or so of it nor use it.

However, this is a Windows only feature
Yeah, sorry but that's wrong. 32bit can see 4GB total, including video cards, cache, etc etc. When running 4GB on 32bit Vista, most I could use was 3096mb. Not even 3.2gb.

A 32-bit OS has 4GB worth of address space. However, the OS must reserve some of the addresses for device and working space. XP usually reserves ~500-800MB. Vista reserves 800MB.

The rest of the available addresses go to memory. Video card memory gets priority assignment over system memory.

It all depends on how you have your memory mapped. Different things have priority to it like Duckie said.

Regardless, your OS can't "see" 4GB or RAM unless it's a 64-bit OS.

This restriction is not present in 64-bit operating systems.

A 32-bit OS can see more than 4GB via PAE. It creates another memory access layer. Instead of going straight to a memory address, the system goes to a table which maps to a few memory addresses. However, this is for servers and other very well-controlled operating systems.

if there is unused memory, vista will automatically use it. It makes Vista run faster/smoother.
Is it necessary? Probably not for some/most people. Is it nice to have? Yes.

I'd say it is necessary. It's a new feature and now no new Windows Operating system should be without it unless it's found to be fundamentally flawed.

That's interesting. I didn't think it could see any more memory because of the actual memory limitations. A 32-bit register meant that 2^32 addresses, or 4 GB of RAM, could be referenced

32-bit address (4GB) = A-G
PAE (16GB) = A-Z

Usually, the system can go straight to address A-G. When using PAE, a look up table is created that the system checks to find memory address of A-Z. However, there is a performance hit to use the table. Even worse, not all devices or drivers know how to use the look up table. They might look directly for address C... but PAE had mapped that address to something else so you get data corruption.

It's only XP and Vista that have this 32bit memory limitation, as they have PAE disabled.
