ram question toshiba m60

I have a 1 gb stick of pc4200 ddr2 ram and a 256 mb pc4200 ddr2 stick. On the toshiba site it says i will lose ddr2 capablity if the sticks arent the same size. is this true? If it is is there a way to solve it rather than take out the 256 or buy another gb.

 

It think you meant dual channel and not DDR2, because DDR2 is just standard of memory. Dual channel is when you pair 2 identical sticks which will create double the bandwidth than in non dual channel memory configuration. Does this have a big effect on performance, well no - you might see increase in performance of programs of bandwidth hungry applications but largely the increase will be miniscule and not noticable. There should not be any problems in adding the 1GB RAM to your existing 256MB. But if you want to make it dual channel then either you'llhave to upgrade to 512MB(2X256MB) or sell your current RAM and get 2X512MB sticks or as you suggestedupgrading to 2GB(2X1GB)

PS - There have been some reports of people having dual channel memory capability even with non matching sticks. I suggest that you try that out first . CPU-Z( www.cpuid.org) will tell you whether the system is running in dual or single channel memory configuration.
