Ram Choice

Hello,
G.SKILL Rip jaws Series 8GB (2 x 4GB) 240PIN DDR3 SDRAM DDR3 1066 (PC3 8500) 7-7-7-18 - $79

OR

G.SKILL Rip jaws Series 8GB (2 x 4GB) 240PIN DDR3 SDRAM DDR3 1333 (PC3 10666) 9-9-9-24-2N -$89

^ If you know how to set or alter the RAM speeds, then I would suggest the 1st one as you can loosen the timings, you can set it to run faster than 1333MHz at CAS 9,...

First choice is superior, see if you can get 1333 cas 8

2nd choice, it's best if you probably don't mess around with their clock speeds.

 

[joelmartinez]

Yes messing with clock speeds is not advised if you have never manually set timings but there really is no harm done if you do it correctly its not goona melt or start a fire (unless at 4.0v or something crazy like that)

This is how you calculate the speed of the RAM, to include latency:

(CAS / Frequency (MHz)) × 1000 = X ns

(7/1066)x1000 = 6.56ns

(9/1333)x1000 = 6.75ns

Therefore, at stock the CAS 7 1066 RAM is in fact faster. But the 1333 will have more bandwidth.

As for which to get in anticipation of finding tighter timings/faster speed, I can't say. Because to be honest ever RAM module behaves completely different.
