Should I have any concern over the brand on memory I put in my PC? I've got a Dell Dimension 4100 with only 128 MB, looking to add another 256 MB. This week, Best Buy has RK-Byte 256MB PC133 SDRAM for $29.99 after rebates. Crucial.com is running 256MB for $47.69. The info on their web site leads one to believe that their RAM is of higher quality than others. Is there a benefit of buying memory similar to what Crucial sells over the brand at Best Buy? Crucial brings up a second question. If I buy from them, I have to decide between CL=3 and CL=2. If CL=2 is "faster" and the same price, why would I have the choice to buy CL=3 in the first place? Thanks for any help.
