Solve : Computer can't find memory?

Answer»

I just installed a 512 mb stick of ram in my compaq presario v2000, and I already have a 256 mb stick of ram in there. So I should have 768 total. But my computer is for some reason only using 640 mb of it. In the bios, it shows all of the ram there. In fact, when I run sisoft sandra, it tells me that I have the full amount, except under the motherboard setting, where it shows me that I don't. So, CLEARLY (I think), some parts of my computer are recognizing the ram, while others aren't. I'm a bit confused--help?If you have the video built in on the motherboard it will take up RAM. Is you video 128MB? Because that's the difference between 640 & 768.

Right, and, in My Computer | Properties | General, Windows will report the total physical MEMORY installed less the amount a shared/dedicated memory in a system with onboard video. So, if the amount of system memory allocated to video is 128MB, then Windows would report 640MB, as it's been trained to do by Microsoft. Quote

I agree
Are both RAM strips the same speed? IE pc5400, pc3200 etc...Quote from: lil_falco on August 10, 2007, 07:31:55 PM

Why ask that question? What does it have to do with the question in the original post?
