It just says Hardware Reserved for 2GB, does not say what is using it. I discovered through some other resources on the system that going into the system information I can view each device and the range of memory it is using. One of the earlier posts did the math for me there.

However, I am unsure why my graphics card, which should have 1GB on the card, is using 2GB of my RAM...

Start with making sure that the heatsink isn't on too tight.. Back off each screw 1/8-1/4 turn, then see if all the memory is available. If that doesn't do it work your way around loosening one screw at a time.

@ gpost3, this isn't as Windows problem at all as he also said Ubuntu only sees 2 GB of the 4 GB.
While it may seem that Ubuntu was having that problem also, the problems seem slightly different. Ubuntu didn't even recognize the other 2, but I never really use it except when windows craps up. Windows however will recognize the other two, but as gpost3 discovered, my graphics card is using up 2GB of my RAM...extremely annoying. I will try your heatsink suggestion when I get home. I stupidly put in a monster of a heatsink that makes cable management a nightmare, and need a new fan as well, so much to do...

You would be surprised how often what you're experiencing happens when the heatsink is on too tight,

Go right above that colored bar you are looking at to processes and it will show you what and how much ram is being used for what. I don't use Ubuntu. You can use Windows 7 all by it's self to see a lot of things.

I don't buy that the heatsink will cause software to malfunction. I think there is a confounding variable here which was fixed while the heatsink was being replaced. It is like the old days when they used to say that coffee is a potential cause of lung cancer but later discovered that people who smoke tend to drink a lot of coffee (and smoking was causing lung cancer). Try the heatsink idea but it sounds stupid to me.

In Windows, it says 2GB hardware reserved. I cannot trace where that is in resource monitor or performance monitor. In Ubuntu, it ONLY registers that I have 2GB of RAM.

Who said anything about software? It has also been confirmed that mounting the heatsink too tight can cause the same issue that pendraggon87 is having. now as far as stupid, might want to take that up with these guys,

RAM Problems? Cooling too Tight? - [H]ard|Forum

Troubleshooting Thread for Incorrect Memory Amounts on X58 and P55/H55/H57 Platforms - The Corsair Support Forums

and just in case you don't like links, this is from the link on the Corsair forums (and no the big red text isn't my doing),

Quote:
Also, be sure to inspect your CPU cooler mount. Over tightening or unequal pressure on the CPU socket can cause the CPU to not seat correctly. Frequently, this translates into what appears to be memory related problems because the CPU/IMC is not making proper contact with the pins leading to the memory sockets. The fundamentals here apply to systems with 3 modules also and especially when overclocking. This applies to P55/H55/H57 also. In any situation where you have these issues and where the above steps do not work, please remove your CPU and inspect the socket for bent pins
which makes it even more fun in that you can possibly bend pins in the socket due to over tightening.

pendra, have you tried running the RAM in single channel mode? And also see if you can take your system to a friend's place and borrow/test his memory on your machine.

Lets keep it a little less Kick you in the xxxx. We all want to learn and help. Questions; can ram be seated wrong; answer yes, please check. Can the M/B have a problem, yes please check this or that. We all do this. We are all on a WINDOWS 7 forum to try and help people using Windows 7 if at all possible. Every thing you see here may or may not help but who ever posted it meant well. If some one thinks another O.S. is better that's okay. Why are you here? If Ubuntu gives you information you like I'm sure they have a web site. Many people here leave instruction of how to use Ubuntu to help with problems and we use them and say thank you. Or don't use them and say thank you, it's your computer you choose. To the best of my little pea brains knowledge their is no operating system that suites every body in every way. Work with us and we will work with you!!!! Layback Bear.
