Thread Starter 
hi am currently using 4gb of corsair memory in dual channel mode (2x2gb) however i have the same memory laying aroun (same timings, speed make etc) however it is only 2gb (2x1gb) is it possible to use all the ram so that i have a total of 6gb?

It may in fact run but at the lower speed BUT it is highly recommended to keep all the ram the same (speed, timings, size....). It is not really a good idea to mix your RAM that way.

Edit: I miss read your post. If the speeds are the same then it will run. Just make sure you keep the RAM with the same size in the same channels.

That's what I do. All I had to do was bump the NB volts up just one notch to make up for the extra stress 4 DIMM's put on the NB memory controller. Works fine for me.

same timings, speed...perfectly safe...some boards don't like 4 dimms being full for performance...

but hey why not throw them in and see if its all good.

6 is better than 4!

I guess with ram the only way to find out is to try...I don't think you can hurt anything by tossing ram in, even if it doesn't work it will just not post,(or it will beep a bunch of times on startup) don't be afraid to try out ram sticks.

Right, I even have mismatched RAM on my older computer which I use for web surfing and the kids use for homework. No biggy and it's not like you'll fry anything by trying, so go ahead and see if you like the performance output afterwards.

Are you running x64 or x32? Vista 32 won't get any more use out of 6gb of ram compared to your current setup.

Did you read the post before replying? The ram is the exact same sans capacity. He should be fine adding the extra ram as long as his OS supports it.

x64! do you think the extra 2gb would even effect the proformance?

Thanks

You should be fine. I'm mixing different brands, timings, sizes, and default clocks. Rock stable.

In gaming more then 4 gigs won't do much but if you run video, music, architecture software and you want to compile data then yes.
