Hi all, I recently upgraded my RAM from two 1g sticks that came with my computer to two 2g sticks, pc8500 at like 1037 mh or something.

4g total, though I know I don't utilize all of that with my 32 bit Vista system, but I knew it would still be better than my old RAM.

But I just noticed that my Task Manager screen shows that I am using on average 29% of available physical memory.

I never looked at this before when I had my 1g sticks in there, so I am not sure if that is normal or not. It seems awfully high considering I am just sitting at my desktop with a single internet window open.

Is that saying I am using 29% of my 4gigs? Or is RAM different than physical memory?

I tried looking it up but can't find the info, sorry I'm kind of new to upgrading computers. =)

Uh oh! I also just noticed that CPU-Z is saying my max bandwidth is PC2-6400 (400 MH). That's not right.... it is 8500 at 1066mh. Did I need to do something with the BIOS? I just pulled the old ones and stuck the new ones in and turned on the machine...

Any help is greatly appreciated.

thats probably because the old RAM you have in your computer is PC2-6400. That makes the PC2-8500 run at PC2-6400 speed

How do I fix that?

Sorry for the questions, but I could really use some help here! Anything anyone can say will be a huge help!

By the way this is the exact RAM I ordered:

It's Corsair Dual Channel XMS2 4096MB PC8500 DDR2 1066MHz Memory (2 x 2048MB)

Still looking for help hours later. Can anyone please at least direct me to a resource where I can find some help?

Bless you to anyone who responds.

32 bit OS's will only see 3.5Gb of RAM, 64 bit will see 128Gb of RAM.

29% is normal, im using 33% of 4Gb with just windows and firefox open, so you dont need to worry about it.
You dont need to say sorry, its what we are here for
Hope that helps

That does help, thank you very much.

Do you by any chance know where I go in my BIOS to make changes to the memory speed? It seems to be only running at 400Mh instead of the 1066Mh it should be running at. I have an ASUS P5n-E SLI motherboard.

try going into the BIOS, advanced, jumper free config, set AI tuning to manual, then FSB & menory config and you should be able to play with your ram speed . Look at a pic on google and im not sure it then will match your BIOS, but it should do.

your board uses DDRII 6400 (800mhz) so it wont run at 1066 only 800mhz but you wont notice the difference.

let me how you get on
