that was said because i did have a issue like that at one time when i discover i wasnt using all the ram i was supposed to be i jumped to 64 bit made a differnce but in turn i have seen some rigs

with memory all in usage no standby no nothing my whole thing is windows will not allow you to use it all
it does hold some ram back that is the whole thing it really didnt have to get this big lol but sometimes my reasoning is not understandable

im like a mad scientist im all over the place

Again I would like to see the reference that windows holds RAM back in some vague fashion. If there is a difference between physical RAM and Available RAM, it is due to memory mapped devices like video cards using up part of the adress space.

How much RAM does your video card have?

Well, I didn't get off the topic, you did and I just responded. You didn't seem to have any problem responding back to me until now...

But in reality it is on topic - physical vs available RAM and understanding the differences, which is a good discussion I think.

Captain boom Boom. I think you may need to use the BIOS memory remap feature if you intend to utilize all of physical memory. I am speculating and reaching beyond my direct experience here but I believe this feature lets you map your video RAM to an address range beyond your physical memory (in your case it would be toe the upper 1 GB of the 16GB address range). Does your BIOS have a remap feature and is it enabled?

RAM 6.0 GB (1.95 GB Usable) WTF?!
What's this all about? Last time I checked system properties it said 5.5 GB usable. Now, today I noticed that my sidebar said that my memory is 40% in use and there's only 1.5 GB available. What's going on here? I was thinking it could be my video card taking the memory, but I didn't change any...
