32GB Corsair Vengeance Notebook 1600Mhz vs 1866Mhz?


Recommended Posts

I've recently ordered an Alienware M18XR2 with the following specs:

Intel Core-i7 3940XM


Intel 520 120GB SSD (externally purchased)

2X2TB WD Green in RAID-0 (externally purchased)

the rest of specs aren't important for my question.


As for memory, I decided to go with 32GB Corsair Vengeance.


Now I have two options:

Corsair 32GB DDR3 1600MHz Vengeance Laptop Memory PC3-12800 10-10-10-27

Corsair 32GB DDR3 1866MHz Vengeance Laptop Memory PC3-14900 10-11-10-30


The 1866Mhz obviously has faster clocks but the 1600Mhz has tighter timings.


I am going to overclock the system to the ragged edge (always had!) and the extreme edition processor won't be bottlenecked by the memory.


In these circumstances, money no objection, which one of the two would you recommend and why?

The largest upgrade DELL offers is a 32 gig 1600mhz kit. So I don't know if the 1866mhz kit would run at 1866mhz on that particular machine. I would contact DELL and ask them before you buy anything..


Here are the two kits Corsair has to offer that have been tested on that machine. Above those results there is no way to guarantee they would work. Even the Corsair results only offer a 16000mhz kit as max.
