and same timings, you'd be better off getting 2 DIMMs at 4GB each and combine those with 2 of the existing DIMMs. You'd have 4GB DIMMs in the channel A slots and 2 GB DIMMs in the channel B slots....for a total of 10GB.
Using 3 DIMMs in a dual channel system or mismatched DIMMs in the same channel suboptimizes system performance.
PS...The triple channel kits can be used on the dual channel systems but they're really geared toward X58/Socket 1366 MBs...otherwise you end up with leftovers/spares/or some variation of system suboptimization.
I have a computer with 4x2GB of 1333MHz DDR3 RAM (this is the model: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=6448106). And I am replacing the RAM in it with 3x4GB of 1333MHz of DDR3 RAM (This exact product: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=41013&CatId=4534). I just want to double check that this will work alright and that I'm not doing anything stupid some how.
And also I want to know what will happen if I keep one of my 2GB sticks in with my other three 4GB sticks. Will that create a problem? Or will it hinder my computer's performance at all?
Thanks very much
