Ok Ive been reading specs on Intel's website...ofcourse looking at the Core i7 2630QM processor and comparing it with the 740QM etc...

I looked at Max Memory support and says 8GB...can anyone explain this...I know since AMD64 that NorthBridge are built in on the processor...

If its true that only 8GB is supported with the 2630QM then whats the whole point having the G73 being max for 16GB?

2630 supports 16GB.

Everything on Intel's web site and documentation says 8GB...

Depends on whether the mobo has 2 slots, or 4. They can take 4M modules. The G73SW-A1 I have here has 4 banks, tho I don't have any 4M modules to test with.

Ok intel rep told me that officialy Core i7 Mobile are capable of handling 32GB RAM...its just that the bandwidth of the 2630QM is only effective up to 8Gb...anything over that is just running trhough a single channel mode

So in a way with the G73's thats on 16Gb Ram...8Gb is on DualChannel and the other 8GB ( if actualy used ) is just running single channel

I would think all 16 is running single channel... *shrug*

I would think soo too, But that is how they sum it up for me...

Clarified it again with Intel...

for the 2630QM, 2720QM, 2715QE models of the Core i7...

If you have 16GB RAM installed and the Applications only use 8GB or less you are running DUAL CHANNEL...Once the Application uses past over 8GB it will switch to SINGLE CHANNEL (Which he said not until further in the future will they have Applcations actualy requiring that much RAM)

Most configs come with 12GB, but if you add another 4GB stick, you can have 16GB.

Am glad someone decided to discuss this issue.

I want to buy a Toshiba Qosmio X770-107. It has the GTX560m (1.5GB GDDR5), great hardware but what worried were:
- Core i7-2630QM (2 - 2.9GHz)
- Memory is maxed out at 8GB DDR3 (2x4GB)

I did some research on the memory max support and all points to the Intel CPU limitation. Even Crucial indicates the machine's RAM is not for upgrade. The laptop comes with only 2 Dimm slots. So my thinking is, 3 years down the line, probably upgrade the CPU to i7-2760QM (2.4 - 3.5GHz) and upgrade RAM to 2x8GB sticks.

Will that work, esp. the memory upgrade bit? I know that Alienware m17x R3 and new Asus G53 have 4 Dimm slots, so am not sure whether machines with just 2 slots have some physical limitations?

i think this just comes back to the point of, it's rather useless to spend money on ram past 8GB, unless you're doing video editing or something that needs it.

ie BF3 recommended ram is still 4GB.

In the case of that Toshiba it's a slot limitation; You only have 2 SODIMM slots. The G74SX has 4 SODIMM slots and supports up to 16GB with the i7-2630QM. Ergo, it's not a CPU limitation.
