RAM: Latency vs Speed???

[DirectorC]

Conclusion: As you can see from the benches, the differences are minuscule.

If you don't want to mess with the memory too much, I'd say you'd be completely in spec with the 1333 if you overclock your chip (i7 920 DO right?) to 3.33 Ghz -All you'd have to do is change the base clock from 133 to 166 and your RAM should automatically be moved to 1333 from the default i7 speed of 1066, permitted you keep the memory timings the same. This is a basic overclock though (no changes to CPU voltages or anything like that and memory is running at rated speed). Of course faster memory can't hurt so the 1600 will give you more headway if you decide to push it more. Even without an overclock, most motherboards' BIOS's are really easy to set the timings in so I'd go for the 1600.

Okay here's my results http://img.techpowerup.org/100105/Capture002257.jpg

If I go to 1833mhz and oc my cpu I can get the top spot on this chart.

wierd, going to do some benchmarking on my system again to see if i can get lower latency with higher bandwidth / timings,

Why not get the 6Gig DDR3 ULTRA TRIPLE CHANNEL DDR 31600MHz C7. This is tested to work on your motherboard.

i ben tempted to c7 but heres something new. newegg says its the ultimate memory for i7. check here

however corsair does not list it in recommended memories for i7. check here.

might be faster for intel cpus to have faster ram than tighter latencies but thats not the case for AM3

for that it likes tighter but ideally because AM3 can go over 1.65v for safe you can get higher clocking and tighter at the same time

overall ram is expensive so 1333mhz sticks might be all you can afford like me!
