    Default NP8130: Memory Slot Numbering & Thermal Paste on GPU Memory Questions:

    Haven't seen these points addressed before, wanted to see if anyone knew for sure / had specific experience.

    A. Memory Slot Numbering:
    How are they numbered? Here's my guess:

    DIMM0- Under the laptop, closest to the motherboard
    DIMM1- Under the laptop, closest to the external case
    DIMM2- Under the keyboard, closest to the motherboard
    DIMM3- Under the keyboard, closest to the keyboard


    B. Repasting TIM with Diamond IC on the GPU / Memory
    I've only repasted my older ASUS system for now, but was wondering for the NP8130:

    -B.1: Do the memory chips come with little thermal pads for transferring heat, not paste?

    -B.2: If so, what was your assessment of the gaps between the copper and memory? (Too large of a gap means the pipe was designed to work with just pads, and will not be able to properly press into position with the thinner paste).

    -B.3: Given all this, if you decided to endeavor, has anyone repasted with positive results using any brand of paste?

    DIMM3- Under the keyboard, closest to the keyboard
    And to be more proper with my question, I realize I should add some clarity.
    In order to bank/pair the memory of different sizes properly would you install them:

    DIMM0- BANK 0
    DIMM1- BANK 1
    DIMM2- BANK 0
    DIMM3- BANK 1

    ...like we often see on desktop motherboards?
    Thus, becoming important to know if you have 4 sticks of memory, and have two different sizes.

    I tried a different approach to get some answers and found the user's manual. It helped some, but not completely.

    On the bottom of the laptop are definitely the "primary" memory slots.
    [See 1st Attachment]


    The two under the keyboard are not similarly "stacked" one on the other, as I thought they would be, which still leaves me wondering about the numbering. My guess is "13" is the third DIMM slot and "14" is the last DIMM slot, since they numbered them like they did.
    [See 2nd Attachment]

    Furthermore, if they call the two on the bottom of the laptop the two that are "user accessible" and "primary" you'd think that they might want you to BANK memory of different sizes, like this:

    [2 of size 'X' in Bottom of Laptop]
    [2 of size 'Y' under Keyboard]

    But again, who knows! I don't.


    Lastly, for the video card, I learned that I can remove the memory chip heat pipe separately from the GPU, which is great, so I can inspect without having to repaste anything. I'll report back what I found out this evening. It looks like from the photos no paste is used by default installation. (Memory chips are clean and black, not gooey and grey like the GPU).

    I'd be interested in this too.

    To at least close the thread as it relates to B. - Repasting the GPU Memory, I assessed the gaps on the memory this weekend, and it does indeed look too thick to paste with Diamond IC7 (for my comfort level anyway). The gap is probably between 1mm and 1.5mm.

    I have sent an email to Innovation Cooling to see if they have any maximum height/thickness that they have successfully tested with, and have seen that their product works well, but I'm not going to guinea pig my new machine


    Reading around notebookreview and the internet... I find that that some people with gaps LIKE this have successfully used ICD. (Chipsets, NorthBridge, older desktop video cards' memory).

    All newer discussions and posts really seem to push you away from pasting memory chips inside the laptop, especially when the stock installation is with thermal pads. Even if you decide to pull the heatsink off the memory to examine it further than I could from the side view, you may rip the pads, and/or I hear that they won't be quite as good as they were, before being compressed, so I don't recommend that either.

    One user has removed his, and is now testing to find replacement thermal pads. Consult this thread for more info:http://forum.notebookreview.com/sage...gpu-where.html
