Off the top of my head, Arma II. And most simulators that have big scenes. Of course, both of the big civilian ones can't be loaded in a ram drive due to the sheer volume of data they have.

Apologies dude, wasn't reading carefully enough. I don't know of anything that will do that, but maybe you could run ARMA in windowed mode so you can keep the resource monitor visible - but that might change your results some =/

Excuse me if I don't take that as being the truth, but just the theoretical limit. As the memory limit in Windows7 (professional and higher) is 192GB, the memory limit for an exe running under it will either be 192GB or lower.

That is the limit determined by hardware. What the OS does is its own business. If I want to I can write a 64 bit OS where executables are limited to 1 MB of memory. The current limit on Windows 7 x64 is 8 TB IIRC.

This has now been said a few times in this thread, to clarify: Unless you run specific 64bit software for those tasks, will more RAM even help? For example the Photoshop "Lite" many people get with their cameras and use are 32bit apps limited to max 2GB, maybe 3GB RAM. You'd need professional products (with prices to match)... to see a difference no?

Short answer: Maybe (probably).

Long answer: It depends on exactly how Adobe set up Photoshop Lite. If they didn't set the LARGEADDRESSAWARE flag when creating the exe, then it's flat-out limited addressing only 2GB memory. If they did set the flag, then even if the exe is 32 bit it could address up to 4GB of memory under win64. Assuming, that is, that the "lite" version uses allocators and algorithms that are able to take advantage of >2GB of memory. I'd say that it probably does, since I doubt it's worth the effort for Adobe to make such a significant change.

I thought LAA flag meant max. 3GB for the application, 2GB without LAA?

By this reasoning I always held that if basic system processes fit inside 1GB (easy in Win7), you are well off with 4GB as long as you are not running specialized 64bit applications. Though a 64bit OS still makes sense to avoid the "management limits" if you also have large VRAM.

If LAA means 4GB max, then 6GB systems would make more sense for more people.

Under 32 bit windows (any version), yes. 2GB for any process, 2GB for the kernel. If you boot with the /3GB switch in boot.ini (you shouldn't) then a process with LAA can address up to 3GB, but the kernel is limited to 1GB.

Under 64 bit windows, a process without LAA is limited to 2GB, same as 32 bit. A process with LAA however can address the full 4GB of the 32 bit address space.



Honestly I would expect that any program with real need to address >2GB of memory would (should) have a 64 bit version. Just flipping on LAA doesn't do much. The program has to be design to actually allocate and use the extra memory to see a real benefit from it.

Take Oblivion for example. With all the hi-res texture packs and so on available for it it's pretty easy to run into problems with the game running out of memory and crashing when it hits the 2GB barrier. You can modify the game's exe to enable the LAA flag, and doing so will save you from some of the crashes. However, the game will never really use more than 2GB, because it wasn't built to make use of more memory.

Hi, I had added a Memory stick for some added RAM w/Readyboost feature. Is there anywhere I can see the added RAM?? I went into system and it does NOT show the extra 2 gb??

Was just doing an experiment for now will probally add some Real memory ltr..

I recently went from 4GB>8GB on Win7 64bit and can't say I noticed much benefit. I'm sure I am getting some benefit, just can't say it is all that noticeable so I wouldn't sweat it if money is tight.

Also, read the below article. It quite clearly states that unless a game is 64bit native it can't see anymore than 2GB of ram available to it. That explains why I see little benefit by going to 8GB of ram because in just about all games it makes no dif if you have 4GB or 8GB, it will still only be able to use 2GB max.
