RAM & VRAD

Are you sure for 2.75go? I compil a big map, and at 1.8Go the VRAD stop. So I have 4go of RAM, but XP 32bits can use 2Go maximum by applications. --Anarkia777 16:21, 31 July 2010 (UTC)

what is "go"? --Pfannkuchen 16:31, 31 July 2010 (UTC)
232 = 4,294,967,296 bytes

2^32 / (1024 x 1024) = 4GB Once you factor out System reserved and video memory you end up with 2.7. If you have less you are using more for video memory. And Vrad doesn't crash when you 'run out of ram', windows simply begins paging ram to the harddrive. (which is slow) --Omnicoder 16:56, 31 July 2010 (UTC)

On task manager your VRAD can use more than 1.8? Hummm I am a problem .... But I thing that 32bit system is not possible to use more 2Go by applications, same with paging Ram. On Catia, a sofware for mechanical, I use 64bits system because on 32bits the max is 2Go. So all desginer mechanical and engeering use 64bits windows. --Anarkia777 20:02, 31 July 2010 (UTC)
