it depends, if you got the dual sided chips you can easily run them @ 2.0v, so you can use them with the new ones. (I have my dual sided chips running @ 1.9v >> 4-3-3-10)
if you got a year ago or more, you probably have the better dual sided chips which overclock very easily.

if you don't know which you got compare to these pictures
1) 2 sided chips which comes with clamps on top holding the heatsink down

2) 1 sided chips which looks like the ones you just got

I have the exact same setup, and I'm planning to mix them together but iI'm not sure what voltage I'll run them at. Guess I'll let the motherboard determine the voltage and run with it for a while to see if it's stable or not. I hope I can overclock them together with ease too.

Thanks everyone. Yes my BL2KIT12864AA804 are from August 2007 and have never given me problems. The bios is kinds funny tho. It's either auto every voltage or you can set each voltage manually. For RAM it only allows you to add extra voltage, and even in the manual setting starts out by providing "memory voltage as required" according to what's in the manual. What the heck is that? Oh well. I don't mind if I Fry $8 RAM so much but I'd hate to damage my good stuff.

bonjonno said:Great. I've got the ones with clamps on top like 1). Do I set the bios to auto voltage? That's how it is now. I believe if I set it up manually, you can choose to add increments of .1 volts, but it doesn't say the actual overall voltage. I'll have to look into this further. So far no replies from the gigabyte forum.

I've got the p35c-ds3r, which has pretty much the same bios
the auto setting one mine is set at 1.9-2.0v (but I've heard its supposed to be between 1.85 and 1.9)
My recommendation, try to put the new sticks in with the older ones, and run memtest with auto voltage setting. If you get no errors after a few hours of memtest, leave as is. If you get errors, manually add .1v and try memtest again.

btw the voltage showing on CPU-Z/CPU-ID is the profile voltage not the running voltage. Use PC wizard or hwmonitor to see the ram voltage. You can also use gigabyte utility that came with the motherboard.

well the new set is rated at 2.0v so be careful going above it. You also got crucial lifetime warranty to back you up all you pay is shipping (about 3-4 dollars with insurance from post office) they even cross-ship.

I haven't tested the new ballistix yet, but I will start on it tonight and will try pushing the limits with it (will try with lower voltage, tighter timings, higher frequency) I doubt they will match the overclockability of our older ballistix since those pretty much are limitless, I also paid $70 at the time, and that was a good deal for it.

Price drop alert --
