M11x R2 Maximum Memory

So Intel says the max memory on the I7 and I5 is 8gb. However, I have seen plenty of times Intel says as such about chipsets and such because at the time of the writing, they had no larger memory amount to choose from.

With that in mind, has anyone attempted two 8gb sticks?

(Yes, I do use a great amount. Given I only have 4 now, but since even that is not getting half the photoshop files I want to work on at the same time. 8GB when I really need to get large files with many layers open with 3dMax* open still may not suffice.)

Dell doesnt support more than 8gb on some of the XPS, however you can still get larger sticks for them. (Example)



On a sidenote that I have never figured out. Underclocked rams CAS will lower? Or will the auto CAS in bios keep it only at what the CAS setting is for the memory at its stated speed? As in say someone got choose from a 1333 or a 1600 both rated at CAS9. Would the 1600 being underclocked drop it CAS latency? Is there a formula for this?



*Which still is with the Optimus drivers on the 335m. I can only get OpenGL to work without any issues making my ability to work with DX Shaders non existent.

 

Your example is two 4GB modules. Because there are only two slots, you'd still only have 8GB. Unless there are higher capacity modules available, you still can't do it with those even if the chipset supports higher capacity.

Each ram stick has a PLL chip that specifies the supported timings for various frequencies. Typically, the lower the frequency the lower the CAS timings but some modules may not have specified defaults for the lower frequencies or may have lazily specified the same timings. Some specify voltages for those frequencies that are out of spec or unsupported by the hardware.

 

8gb was the highest you could get for the R2. 16gb is the highest for the R3.

 

I know better than that. Shame on me. I misread 8 X 2.

But has anyone tried 8 gig sticks?

Thanks for the feedback on the CAS. Sounds like if one want to try such, to use better quality ram as it is where it has more chance of not having half assed PLL chips.
