Alright I want to add more ram to my PC I currently have 2 512 strips running in dual channel I know if I add anthor strip it would disable dual channel for me. Will it be faster to have more ram without dual channel than having less ram and dual channel enabled?
Yes, it will disable dual channel. Dual channel requires matched pairs of memory sticks in order to work. As for it being better or not, it depends on what your doing, but for gaming, which i assume is what your asking for, i would stick with having dual channel and the much higher bandwidth you get with it.
I went from 2 gig dual channel to 2 gig in single channel and in games or any other application have noticed no difference in real terms at all.
Oh okay so the amout of ram is more imporntand than the speed of it right?

No. Which is better is going to depend on what you're doing and where your rig sits relative to everything else.
As a general rule, something like photo or video editing will see more benefit by increasing the overall amount of memory, versus the overall speed. They need a lot of space to cache data, but don't have extremely high I/O requirements. An application which requires a lot of memory accesses (reads and writes, like a database) will probably draw more benefit from dual channel's "no downtime" than an overall increase in the amount of memory. Games really tend to split the middle. BF2, for example, will probably play better with 1536MB in single channel than 1024MB in dual channel--it needs the extra memory. But 2048MB in dual channel will probably be somewhat faster than 2048MB in single channel, assuming that memory is actually creating the first bottleneck.
The impact of dual channel is easily measureable with various benchmarks; it's clearly there on a theoretical level. Whether or not it will create a noticeable impact, as noted, will depend on what your primary needs are.
As an aside, adding a third stick to an AMD platform might also force the 2T CMD change. In that case, you're definitely better off sticking with only two sticks.
I don't have a AMD rig I got a Pet 4 3 GHz not the fastest chip but it's good enough for my needs. Would oblvion, Half life 2 and FEAR benift from having more ram? Also would having more ram speed up my system proframce such as booting up time and scrooling around in windows?
Oblivion and FEAR probably would prefer more RAM. HL2 not so much.
No, unless you've got that godawful eyecandy turned on with a lot of crap in the background. Then it might.
Alright then I'm going for 1.5 then i'll get 2 gigs later on. If I have 4x512 mb's would I be running dual channel?
Thats exactly what i had m8, as long as they are pairs they will work fine.
