Can i do this?

[driverdj2000]

i currently have a pair of these installed in my system
http://www.memoryc.com/products/des..._24-Dual_Channel_kit_for_Intel_P55/index.html

Can i put these into the other 2 channels?

i know it would work but is there a chance of problems etc.?
would i be beter off getting exact matches?
the timings and voltage seem to be the only difference
id only risk it if i was 100% certain there'd be no issues,as you can see there's a price drop on the red ones.
cheers in advance!!

I would go for another pair you already have. Yes the timings are a bit different, however,
the board will downclock your current sticks to match the performance of the other sticks. (slower)
But yes, it is possible. No, I would not recommend doing it.
