Is this ok

[spawn1980]

I just ordered a (G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600) Just to get my rig up and runing and later on I want to add a 8gb. The problem is the only 1.5v dual channel 1600 8gb is the ripjaw series (G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600) and the one I bought is not a ripjaw series. Is it possible to mix the 2 series if both lac,volt, match but not the timing.

Timing The 4gb is: 9-9-9-24
Timing The 8gb is: 9-9-9-24-2N

So you want 12GB eventually? Is this going on a X58 platform? We do not recommend mixing memory packages. Different models use different IC chips, so they may not sync well with others.

Thank you
