Intel i3-2310m question regarding RAM

I'm looking to order a Toshiba Satellite P740-BT4N22 and have it custom built to my specs. I've decided to go with the Intel i3-2310m processor and right now they are including 6GB DDR3 1333MHz SDRAM for free. A local computer tech told me that I need to stick with either 4GB or 8GB of RAM with this processor or it will actually slow it down (because it is dual core). Is this true? Will having 6GB of RAM actually be detrimental versus 4GB of RAM? Also, how big of a difference will I notice between a 5400 rpm and a 7200 rpm hard drive?

  1. The Ram is Dual channel meaning it should be in identical pairs. If the RAM is 2 x 2Gb + 2 x 1Gb tghen its fine but if its 3 x 2Gb then it may run better as 2 x 2Gb. RAM does not come in 3Gb sticks so it must be one of them.
  2. On their website they have it listed as 6GB DDR3 1333MHz SDRAM (4096MB+2048MB). So I assume they are putting in one 4GB stick and one 2GB stick? Does that sound like a good configuration or should I spend the extra $80 to jump up to 8GB?
  3. Get 8GB.

    The hard drive is literally the slowest component in modern computer systems. Anything you can do to make it faster will speed up just about everything you do on your computer. Get the 7200RPM drive.
  4. Based on Toshiba's site this laptop only has 2 memory slots. Because of this if you put the memory in unmatched pairs (same size and speed) you will drop out of dual channel mode and into single channel and this can slow your performance down a good bit. So you want make sure you are in matching pairs go with 4GB (2 x 2GB) or 8GB (2 x 4GB) for best performance. You can read some more information on this laptop model at

  5. +1 sorry I didn't think of the 2Gb + 4Gb possibility
