RAM lost while using Partition Magic V6

September 1, 2011 at 21:08:21
Specs: Windows 7, 2GHertz/4GB installed (usable 3GB)
RAM lost--My hp laptop Compaq has 4GB RAM, however, upon using Partition Magic V6 on my Windows Vista it gave an incompatibility error message, my computer personal still used the Partition Magic V6 program on my laptop to partition the hard drive, after doing so, we noticed that the RAM became only 3GB and not 4GB as listed initially; we then loaded Windows Vista and 7 and although the RAM reads 4GB but the usable amount is now only 3GB. Why is the usable amount not 4GB as installed? Did the Partition Magic program ruined something in the hardware to decrease the RAM usage from the 4GB installed to only 3GB usable?

Please, how can we check the computer and return the usable RAM to be 4GB?

If this is a 32 bit OS the maximum usable RAM will be roughly 3 GB. Partition magic had nothing to do with this. You will never get 4 GB with a 32 bit OS.

Do not install Partition Magic (any version) on Vista or later as it is not compatible.

Thanks for your speedy reply LMiller, I have Windows 7 Ultimate 64 bit OS and it now reads installed memory 4GB but the usable amount is only 3GB. Does that mean my hp Compaq 6720s laptop can only use 3GB RAM even if I installed 4GB?

The reason why I think it may have something to do with Partition Magic V6 is because before loading Partition Magic on my Windows VISTA, my computer read 4GB RAM and immediately after using Partition Magic and restarting the computer, it read only 3GB.

So what should I do now? Does it mean my computer cannot run 4GB RAM now on my Windows 7 Ultimate 64 bit OS?

I have Windows 7 Ultimate 64 bit OS with intel Core 2 Duo, it now reads Installed Physical Memory 4GB RAM, Total Physical Memory 3.99GB, Available Physical Memory 2.52GB, Total Virtual Memory 7.98GB, Available Virtual Memory 6.42GB.

Why is the Available Physical Memory only 2.52GB and not 4GB as installed? Does that mean it only use 2.52GB RAM even if I installed 4GB?

Your laptop uses some of that memory for your video memory, probably a minimum or 500MB or possibly up to 1GB. If you just shrunk the Vista partition to make room for Windows 7 then the Vista partition should be the same and the Windows 7 partition would set its own defaults. If they are showing exactly the same then it may be already set in your BIOS, in which case no program or software could change this. I doubt that it really changed anything and you just did not realize this, 1GB used for decent graphics is about right. If your system can accept more memory then consider adding more rather than reducing your graphics performance.

I don't have a video on the laptop, it didn't come with one nor do I attach one to it. I only have Windows 7 Ultimate 64 bit OS installed. The old Vista was removed when I installed Windows 7 Ultimate.

Forgive me, I'm not knowledgable about computers.

What I don't understand is if me computer reads: Installed Physical Memory 4GB RAM, Total Physical Memory 3.99GB, Available Physical Memory 2.52GB, Total Virtual Memory 7.98GB, Available Virtual Memory 6.42GB, does it mean that no RAM has been lost? That 4 GB RAM is ALL being used and not 3GB RAM?

To drive your monitor you DO have video or you would not be able to see anything. Laptops and budget desktops use graphics chips on the motherboard but unlike added graphics cards they do not have dedicated graphics memory so the graphics require some of your installed memory to be reserved for it. This is where your missing memory typically goes. This is usually up to a maximum or 1GB. In your original post you indicated: "we then loaded Windows Vista and 7 and although the RAM reads 4GB but the usable amount is now only 3GB"; but now you are saying that it is even lower. If you show 3GB or a little bit more then that is normal, if you are actually showing less than 3GB by a significant amount then you may need to make a setting adjustment. This setting I do not have personal experience with so I will leave that to someone else to answer for you, just confirm the exact amount again as an answer.

Fingers: From your above reply, now I understand what you mean that some of the RAM is used for video/monitor which I didn't know before.

What confuses me is that my Avaliable Physical Memory is around 2.65GB, it fluctuates around this mark; is it normal to have this low figure? I really don't understand computer well, I'm expecting that it should be closer to 4GB but I may be wrong in my expectation. I'm getting this figure from System Information.

The other figures read as such:
Installed Physical Memory (RAM) 4.00GB
Total Physical Memory 3.99GB
Total Virtual Memory 7.98GB
Available Virtual Memory 6.57GB

My questions now are:
Is the 4GB installed RAM all being used or is only 3GB of it is being used? If 4GB is being used then there is no problem. If 3GB is being used then how do I maximize it to 4GB? Do you think Partition Magic had anything to do with changing the RAM usage?
