There's armor on the GPU I've noticed. It's like a big black plate. How do you remove it? ( Future reference if I need to repaste. )

Have you looked for some dissassembly videos or guides?

Yeah though sadly they're only down to the fans for cleaning, and in Spanish.. LOL!

Sounds like the back plate mate, can you take a pic of it and upload for us please?

I had been thinking that, though inspecting the otherside of the motherboard there didn't.... seeeem.. to be any screws? I have no idea how it worked. But there's just some weird armor on top of the chips. Got the ROG logo on it and everything.

If you think that's armor then you probably shouldn't be removing/messing with it. I am pretty sure what you are referring to is the heat sink(s)...

Darnassus, I haven't pulled it myself, and there doesn't seem to be a youtube G750 specific video, but there are some G class heatsink removal videos, I broadened the search to "asus laptop replace heatsink" and this one shows unscrewing the heatsink attachment and swinging out the heatsink, maybe find and watch a few more before giving it a try on your own :)

Another thought is to have a laptop service / repair company do it for you...

See that silver metal plate over the CPU? It's that, but it's a massive black plate on top of the GPU. I guess there was some screw on the other side..

Might grab some MX-4.

Darnassus, the old notebookreview article with disassembly pictures...
http://forum.notebookreview.com/asus-gaming-notebook-forum/726296-asus-g750-disassembly.html

...shows the X over the CPU has 4 screws around the CPU holding the giant Black Shield in place :)

You can see the screws missing in this shot...

And, you can see the screw posts left in the board around the CPU after removing the heat sink / shroud:

Ah I see.. interesting. I guess when I saw it last I didn't notice because it's all black.

us18x, the photo's in this thread make it look like there are already heat spreaders/pads/sinks connecting to everything on the motherboard, and they look just like your RAM heatsinks - I think these are for surface mount memory chips, not SODIMM's.

Are you thinking of putting these on the SODIMM's? That is kinda tricky, the SODIMM's are sandwiched in there pretty tight. Putting those on might keep the SODIMM's from clicking in place. I guess you could try them :)

2 per SODIMM, yup, you will need to pull the top plate / keyboard to get at the other 2 SODIMM's.

There isn't a temperature probe on the SODIMM's, but I doubt they are running hot - unless you accidentally put in 1.5v instead of 1.28/1.35v SODIMM's :)

Darnassus, yup, black on black against a dimly lit area makes it hard to see unless you get the light at the right angle.

Let us know how it goes, you are re pasting? I wouldn't lay down the past as thick as they have it in the video or photo's - unless that paste is the really thick stuff that is supposed to bridge a large gap between the chip and the heatsink - usually pads are used for those spots - you will need those too - or need to goop up the spots that have no reach to the heat sink / spreader - also, make sure whatever paste you use is non-conductive - as it could drip in time and short something out.

Here is an old post from adamseyes where he mentions the pads:

Here is a recent thread on newer compounds, and they mention pads in there too somewhere, I will edit if I find it.

From Response #54:

Re: ShinEtsu thermal paste

2 weeks and 40 hours of gaming later still holding strong, so it's at least better than MX-4 LOL

Better than TX-2, NT-H1 and AS5 probably as well. None of those pastes have been durable for me in highly stressful conditions.

Take lots of photo's / video :)

I look forward to your posting when you are done :)

Oh I thought the photo is for the last year model so this year model is all covered up with copper heatsinks? to answer your question is yes I did put 1.5v rams and they are the high speed ones the 2133mhz, I used them on board of my older laptop G750JX and had no issue at all it also jumped the ram score from 7.7 to a whopping 7.9, the CPU technically is the slowest part in my laptop.
4014240144 I have 4*4GB installed on board already.

us18x, did you miss the sticky thread cautioning against using 1.5v memory, "Upgraders: 1.35V memory is required!"

Upgraders: 1.35V memory is required!
http://rog.asus.com/forum/showthread.php?33744-Upgraders-1.35V-memory-is-required!&p=272284&viewfull=1#post272284

You will risk damage to your CPU long term, heat isn't the only problem... you could sell the 1.5v 2133mhz memory, and get some 1.35v 2133mhz memory:

Well, it's official. The G750 Haswell boards apparently support 2133MHz (1066MHz) memory. With 1.35v modules nonetheless. Here's the cpu-z snippet.

As far as the heatsinks, the G750JW/JX/JZ are mostly the same as the G750JM/JS/JZ internally. If you pull yours apart, please take some photo's if there are differences.

Both models are identical and I am aware of the CPU might go bad in time but again I couldn't find 2133mhz that are 1.35v... all I found is this one in the picture :/

us18x, in the G750's the CPU is soldered to the motherboard, so that would mean your laptop would be dead without a motherboard replacement if your CPU dies, and if it dies under warranty Asus could refuse to repair it due to the misuse caused by using 1.5v memory. :(

At least there is awesome new memory that runs at 1.35v at high clock rates, like the links I posted above, and these:
