leslieking Posted February 11, 2009 Share Posted February 11, 2009 Hi, Leopard use more than 4GB of RAM in 32Bit mode (for example 8GB)? I have 4GB memory and OS X is preety fast. More memory improve the OS X speed? Thanks! Link to comment https://www.insanelymac.com/forum/topic/152559-8gb-ram-worth-the-money/ Share on other sites More sharing options...
CatZilla Posted February 11, 2009 Share Posted February 11, 2009 I have 6 and it actually accesses all 6 (uses only 1 though). Link to comment https://www.insanelymac.com/forum/topic/152559-8gb-ram-worth-the-money/#findComment-1077546 Share on other sites More sharing options...
Bit Shoveler Posted February 12, 2009 Share Posted February 12, 2009 Most applications won't use more than 3GB by themselves, but if you have several big applications open at once (e.g. Adobe Photoshop, Adobe Lightroom, Safari or other web browser), you should see a big improvement in responsiveness with all that RAM. At least that's my theory, I have 8GB too. Link to comment https://www.insanelymac.com/forum/topic/152559-8gb-ram-worth-the-money/#findComment-1077802 Share on other sites More sharing options...
shavex Posted February 12, 2009 Share Posted February 12, 2009 This is a topic that can be directed toward memory paging I have 6 and it actually accesses all 6 [/qoute] That is impossible. As you get higher than 3 GB (whether it be x86 or x64) you will lose memory space. For example if you did have 8GB of RAM, if you looked at how much is accessible it will be around 6GB. Plus due to paging, this will actually slow down your computer. Popular belief says that the more RAM the faster your machine will go, this is a very false statement as GHz/MHz is how you determine speed. The most you will ever need (until they figure out a new way to page memory) is 4 GB for anything! Worry about the Processor, you get more out of it for your money.

leslieking Posted February 12, 2009 Author Share Posted February 12, 2009 The computer with 4GB RAM work faster than 2GB! Especially Firefox scrolling not lag anymore! I think the difference in speed is pretty big between 2GB and 4GB.. Is hard to believe, 8GB slow down the computer.

CatZilla Posted February 12, 2009 Share Posted February 12, 2009 @shavex not true. it caches all of my 6 gb, leaving only about 150 mb uncached (i don't know if this is the term used, i use the russian interface).

Bit Shoveler Posted February 12, 2009 Share Posted February 12, 2009 @shavex: A 32 bit operating system has a hard 4GB limit. IO space keeps the last 3/4GB or so inaccessible. Leopard on the Core 2 and newer Intel chips (and probably any AMD chip since Athlon 64) is 64 bit, it has a much higher limit on memory size. Most individual applications are still 32 bit so they can only make use of 3GB or so. OSX is pretty aggressive about using unoccupied RAM as a disk cache.

Nick14 Posted February 12, 2009 Share Posted February 12, 2009 Leopard is A 32/64bit hybrid which means it can use 8GB ram and detect all of it Link to comment https://www.insanelymac.com/forum/topic/152559-8gb-ram-worth-the-money/#findComment-1078588 Share on other sites More sharing options...
