Can dual channel RAM be mixed with non dual channel?

Memory itself is never "dual channel".
Your memory controller on the CPU decides if a pair of memory runs in dual channel mode or not.
If you have 4 sticks with a Venice Core, you will be running 2GB memory in dual channel mode @ 2T timmings.
 
My current bandwidth is ~5400 MB/s. I'll assume that means I'm running at 1T, right?

I don't want to lose performance, but I do want to upgrade to 2GB memory. Is there a way to do this without replacing my current 2 x 512MB pair with a 2 x 1GB pair?

No, with 4 sticks, you have no choice but to go 2T.
 
Do a search here in the forum Pretty extensive bandwidth tests show that outside of SiSandra the 1t way outperforming 2t myth has been discredited. Most tests show 1 to 2% difference in performance. SiSandra being a notable synthetic exception
