| 809989 | 2009-09-14 02:27:00 | Hi, my current system has 32bit vista with 4GB ram. Windows only shows 3Gb because of my graphics card etc etc. So I am thinking of upgradng to 64bit. I have been told that when I upgrade that windows will still only use 3GB because the graphics card uses some of the ram? Is this right or hav I been told lies? | xyz823 (13649) | ||
| 809990 | 2009-09-14 02:31:00 | You've been fed porkies - if you upgrade to a 64bit operating system, you will be able to see and use the entire 4GB. The limitations they were talking about apply only to 32bit Windows, not 64. |

| 809991 | 2009-09-14 02:39:00 | Just make sure there are 64 bit drivers for EVERYTHING you've got. Otherwise it wont install / work. 64 bit on this says my vidcard has 3067 mb ram. Its only 256mb | Speedy Gonzales (78) | ||
| 809992 | 2009-09-14 03:30:00 | My win 7 64bit shows 4GB RAM installed but there will always be a sharing of RAM with the gfx card regardless of 32/64bit. Under graphics mine says there is 512MB dedicated memory (on card) and 1.79GB shared system memory. | linw (53) | ||
| 809993 | 2009-09-14 06:24:00 | So trying to get my head around this...laptop says that dedicated graphics memory is 512MB and shared system memory is 1278MB. What is the shared system memory? and so when on 64bit I will be able to use the FULL 64bit? Or will there still be X amount of ram taken out? | xyz823 (13649) | ||
| 809994 | 2009-09-14 06:25:00 | Just to clarify, so how does the video ram sharing thing work? | xyz823 (13649) | ||
| 809995 | 2009-09-14 06:29:00 | It'll probably change, depending on how much ram youre going to install in it. Once 64 bit is installed. Altho 3 or 4 GB maybe the max, if its a laptop. In which case, you may as well stick with 32 bit | Speedy Gonzales (78) | ||
| 809996 | 2009-09-14 06:35:00 | yup laptop already has 4GB ram, and 32bit is only using 3Gb of it. So if I upgrade to 64bit will Windows address the full 4GB?? Its just because if I can get the extra 1GB when upgrading to windows 7 I will go 64bit rather than 32. | xyz823 (13649) | ||
| 809997 | 2009-09-14 06:39:00 | Just to clarify, so how does the video ram sharing thing work? Via memory addressing. 32bit is 2^32 or 4,294,967,295 bits or 4GB. Windows sets aside part of this memory addressing for the GPU and other components (a 512MB GPU would take 512MB from this). RAM is left with a max 3.25GB of this memory range. 64bit however is 2^64 or 18,446,744,073,709,551,616 bits. As you can see we have much much more to play with. The threshold increases from 4GB memory-addressing to 16 exabytes (each exabyte is a billion GB's). So yes go for 64bit. It will allow you to use all your RAM. |

| 809998 | 2009-09-14 06:41:00 | Have you checked to MAKE sure there are 64 bit drivers first?? Before deciding to install 64 bit. You also have to make sure the CPU in it supports 32 and 64 bit. If it doesnt 64 bit wont install | Speedy Gonzales (78) | ||
