From 32 To 64 Bit - Does It Matter?

[Destiny]

I use windows 7 ultimate 64 with 4GB of RAM 8 months ago and it ran fine with MOH 2010 and BFBC2... now I have 8GB of RAM because they are so cheap...

Same here,i also like messing about with ramdisks.

Graphics card don't map their entire memory into PCI space. My 1G video card only maps 256M, and I think that's typical. BIOSes can make that worse by address rounding and allocated more space than the card actually needs.

With a single PCI-Express card the amount of memory lost typically ends up being 0.5G or 0.75G.

Typically? Maybe. But there are definitely some cases where the loss is much higher, up to 2GB.

Typically?

Yes, typically. That's why I used the word. It doesn't mean "always".

32 to 64 bit os not going to matter for most games. Very few games have a 64 bit version. 32 bit applications are limited to 2GB of memory per application. If you have at least 2GB installed and are not running other applications while gaming then you are not likely to see a difference. You could have 128GB of ram and the current games will only use 2GB without a 64 bit version of the game. A developer would be foolish to produce a game right now that was only 64 bit. 32 bit is here to stay for quite awhile. Even MS isn't killing it off yet as win8 will have 32 bit and 64 bit versions.

Well, except it's wrong.

Video cards actually do "typically" map their entire memory within the first 4GB, taking the place of normal usable memory.

Nope.

This long out of date article shows a 256MB card mapping 256MB of memory, the amount I said I thought was typical.

I'm not sure why you would expect anyone to think this post was credible.

Nope. Check your own system.

Look, I'm know I hurt your feelings by calling you a fanboy in that thread about Diabo III, but trying argue with me about something you're utterly clueless about isn't likely to give you any satisfaction.

You can check in the device manager (view,resource by type,memory). My 1GB 5870 is using E0000000 (3,758,096,384) to EFFFFFFF (4,026,531,839) which is 268,435,455 bytes or just under 256MBs. The 2nd output is also mapped so its probably 512MBs total.
