Is that true? Xoticpc.com states that!

no...no...it is wrong!!!Sandy Bridge 2nd generation that starts from 2630\2670\2720 etc. supports MAX. 1600 DDR3 ram

could you please add link to that info?

I want to upgrade my 8gb 1333mhz to 16gb 1600mhz but I want to know if it is compatible.

Only the Extreme Edition CPUs support 1600MHz memory, such as:

http://ark.intel.com/products/53478/Intel-Core-i7-2960XM-Processor-Extreme-Edition-(8M-Cache-2_70-GHz)

Normal dual and quad cores only support up to DDR3 1333.

ark.intel.com lists all the CPUs and tells you everything :)

Was she mistaken? :/

HIS post was refering to a G73 and part iii confirms no support past 1333. My G74S came with samsung 1600's clocked at 1333. I believe the bios sets 1333 by default but there's a beta bios that allows tighter timings.

sorry for sounding like a noob but does the asus g74sx support the 1600mhZ technology??

i really don't think so. even if it supports probably it will be only in 2 of the 4 ram slots..

that's why we are waiting for a new bios to be released.
1. ram compability
2. ram max ammount (currently in the 16gb)
3. there are people than really need the numlock key
4. touchpad (although is not a software problem)
5. screen flicker (again is probably not a software problem)
6. some issues with the USB3.0

feel free to add any point.. :D

My G74SX came with 1600MHz dimms but they are set to 1333. As was mentioned earlier the CPU (http://ark.intel.com/products/family/59136/2nd-Generation-Intel-Core-i7-Processors/mobile) does not support 1600MHz. I don't think there's a bios available that will play with ratio's and set 1600 as an overclock.

small mistake...only from 27xx sandy bridge mobile version supports 1600 ddr3 acc. to this http://en.wikipedia.org/wiki/Sandy_Bridge

If you're fine with running 2x4gb sticks, I got Kingston HyperX ram to work at 1T 1866.
Again, that's only 8 gigs of ram though.

Nemesis: you've got me intrigued with mention of a beta BIOS that allows manipulation of the timings. Some software responds better (i.e. more performance) to latency timing tweaks than to MHz overclocks of the RAM, so a BIOS that allows this is definitely a step forward.
Is this released for general testing among the community? I'm also hoping a new BIOS will support 32GB RAM (the max for the 2nd gen SB mem controllers).

BTW, I tend not to believe ark.intel too much, as their max specs are always a little behind the times.
