ram issue?

[arbateman]

Hi there I have a y570, 6gb of ram. The ram is advertized as ddr3 1333, but Spceey is reporting t he speed at around 665. There seems to be no spot in the bios to change or tweak this. Any suggestions?

thanks

You can look at this article about DDR3 and its properties in wikipedia http://en.wikipedia.org/wiki/DDR3_SDRAM

To cut the long story short, ddr3-1333 can perform 1333 megatransfers per second using 666MHZ bus clock, so what you see in your program is absolutely normal.

thanks so much, I always found the clock cycles confusing.
