16GB RAM on GM45

Tell me about it, the memory controller on the 920xm, is listed with 8GB max memory, strangely, it handles 16GB just fine .

 

Yup.
And if I'm not mistaken, there are laptops with 2670qm which are offered with 32BG RAM when the 16GB is supposed to be the official maximum for that cpu (at least per intel).

 

With so many variables better if you can borrow the memory and give it a try.

 

For those interested, I recently tried 8+8, 8+4 and 4+8. No combination managed to POST, all I get is a constant beep. Oh well...

 

They said the chipset in my laptop only supported 4gb ram yet i have 1gb and 4gb stick in it @ 5gb and TirTurbo has 2x 4gb sticks in his @ 8gb. The truth is probably that your chipset does support 16gb.

 

I was wondering if you managed to get a single 8GB module to work. My notebook's specs state a maximum of 8GB, so would a single 8GB module suffice, or would I need 2 x 4GB modules?

 

No, single modules did not work either. Max 4GB per module.

 

The GM45 chipset supports up to 8GB RAM (which is what I mentioned in my first post on this page).
Intel's info on those (and PM45 chipsets) is fairly consistent with what the hardware itself allows, and since 8GB RAM is an apparent maximum, you would have to use 2 sticks... each being 4GB to result in 8GB that would actually work.

 

Actually if I remember it is 4 GB per bank for the PM45 & GM45. Now for the rare system with 0, 1, 2 and 3 banks then 16 GB is possible................
