Kingston CL4 667MHz 200-pin RAM

#1 Post by Marin85 » Tue Jun 10, 2008 5:35 pm

Hi,
Is it possible to run Kingston HyperX soDIMM PC2-5300 667 MHz Low-Latency CL4 RAM in a T7400 Lenovo mobo (FSB 667 MHz) like the one in my Z61p? :)

most high-quality 667MHz SODIMMs are timed 5-5-5-12 and the kingston hyperX SODIMMS appear to be timed 4-4-4-12.   since the tRAS numbers are the same (12), i doubt you'll ever notice a difference.

in my opinion it would be a waste of money. ;)


you can read more about latency numbers here: http://en.wikipedia.org/wiki/SDRAM_latency

Yup, I´ve just wasted 15 € :) Now I feel bad, but, you know, those 4 GBs looked so nice... (I know, I know I can´t utilize all 4 GB with my Z61p) :P

Cheers
