Hi all,

I have had 2GB (2 x 1GB) DDR2 800 (PC2 6400) RAM for 2 years now and was wondering if it is safe and/or beneficial to add a third, new, identical stick of RAM to my system.

1. I am currently using "dual channel" and wasn't sure if the 3rd stick would be worse than this.

and, more importantly,

2. Is it safe to mix 2 year old RAM with new RAM. Same brand (G.Skill)

Here is what I currently have:

And here is what is in question:

I appreciate your time, thanks,

Andrew

I don't know if your RAM will have any problems, but I'd go with the 3gb. 2gb isn't enough in this day and age

i don't think you can run dual channel with an odd number of sticks.

Is 2x1GB @ dual channel better than 3x1GB w/o dual channel?

I'm about to purchase an item on newegg and can get it for much cheaper ($18) IF I buy it with hardware. So, I can effectively get this 1 GB for < $10.

Thanks for the replies!

I'm pretty sure that would depend on what exactly you're doing. If you need more memory or memory bandwidth. However, depending on your motherboard, you could add 2 more 1GB sticks and effectively have dual channel with 4GB...but, as mentioned earlier, it would be better to just get a 2x2GB kit. This would avoid any issues with the sticks 'playing nice' with each other, allow for better overclocking, reduce the risk for errors, etc...
