Question about memory

I hope I'm putting this in the right section..

Anywho, I'm fairly adequate when it comes to computers, I've taken A+ at school and stuff like that, but most of my knowledge is self taught

I just had a question regarding my laptop though, my video card has 64mb of dedicated memory, and in the bios I have the option to boost that to 128mb.
My question is whether the change will be more positive than negative or what.

I don't know much about dedicated and shared memory, so I'd thought I'd ask before doing anything.

Thanks

*edit*
Oh and I think it would be good for me to tell you that I am a gamer. And I play more of the graphics intensive games, and they run well on medium to low settings, but on higher settings they just freak out. And basically I'm wondering if the change will help or hurt in any noticeable way
 
I have never before heard of beeing able to just conjure graphics card memory out of nowhere before, that is most certainly a new one on me.

If you want more performance, what is the model and manufacturer?

Just most now have an overclocking software that runs through windows, you can improve the power of it by overclocking right through your operating system really easily
 
If you have the option to disable any additional memory beyond the 64MB dedicated I would do that, otherwise I would use as little shared memory as possible.

If you want you can run some benchmarks on various settings and see which one performs the best.
 
It says it's a Geforce 7150m/nforce 630m
I was restarting my laptop and accidentally hit f10, which brought me to that little system screen, and I saw a part about my dedicated video memory.
so I clicked on it to see what I could change it to, and it had 32mb, 64, and 128

What always confused me was that sites like "can you run it" said I only have 64mb of video memory but dxdiag says I have around 1300mb
I thought it was because of dedicated vs shared memory

This is common in the case of integrated graphics. By design they share part of the slower main system memory for graphics processing. They do not have a dedicated, fixed amount of memory, thus you can assign more or less of the main memory to the GPU.

This is an integrated graphics chip. As such, it can be assigned more or less system memory as I mentioned above. Some IGP systems can use up to over a gig of system memory...but... I completely agree with Omega. While you can assign more memory to your graphics, keep in mind that it will take away from the overall system memory your OS an programs will have access to. You will not see much of an improvement in performance either by upping the shared memory allotment.

Only increase this amount if you are running a game that requires a certain amount of graphics memory. And, even in this case, said game will probably perform poorly with an integrated system in the first place. There is an order of magnitude difference in performance of integrated vs dedicated systems.

Oh right, i knew that, i thought it meant the onboard memory, the memory that is on the graphics card itself. I was thinking way too much inside the box i suppose, thanks for clearing it up though :P
