G750 Upgraders: 1.35V memory is required!

X-ROG
Level 15
Please note we fit 1.35V memory into our G750s. New Haswell CPUs require this and using 1.5V memory can cause problems along the lines of:

> Overheating
> Damage to the CPU IMC (due to the increased potential difference)
> Greater battery use than our stated values.

Also remember for every DIMM you add you increase the power consumption by 1-3W each, depending on what you buy.

Once I get ahold of a G750 to borrow for a few days I'll do an upgrade guide.

I need to increase & upgrade my G750 memory, either adding more of the same brand/spec. or replacing the lot with upgraded memory 1.35v.
Having reading through this very interesting thread it seems one or two people have fitted and are running DDR3 2133MHz or DDR3 1866MHz memory.
Has anyone here fitted G.Skill Ripjaws DDR3 2133MHz SO-DIMM or G.Skill Ripjaws DDR3 1866MHz SO-DIMM and found any stability issues on their G750 at either of these upgraded memory speeds ?
(note - both of the above use Samsung DDR3 SDRAM memory chips)
Is anyone running with any other brands of 2133MHz or 1866MHz they find work ok and are stable using 1.35v ?
Is it a case of fit and forget or is anything else required to ensure they function ok ?
Thanks.


Light, this is such a long thread now, but both G.Skill 1866mhz and 2133mhz parts have been mentioned and do work fine. 🙂

And, there is another post apart from this Memory sticky thread about the 2133mhz part:

Hi Hmscott

I went through the whole thread and downloaded both programms to check my ram model. I have a 8gb used in one slot, Samsung m471b1g73qh0-yk0 1.35V. Could you please do me a favour and suggest which model of ram should i go for? I am interested in upgrading my ram to 24gb.

Many thanks in advance.

Protervis, you answered your own question, you should get the same memory make/model you already have installed, get 2 or 3 more of the Samsung m471b1g73qh0-yk0 1.35V 🙂

You could also replace the Samsung m471b1g73qh0-yk0 1.35V and replace it will all new memory - all the same make and model 1.35v SPD memory.

Googling Samsung m471b1g73qh0-yk0 1.35V there are lots of places to get new SODIMM's:

There are a bunch listed on ebay - always verify the part number on individual listings on ebay, sometimes there are keyword hits but the actual item isn't that exact number - beware.

I bought my 8GB Hynix SODIMM from ebay, a Macbook Pro pull/used, matches the other 3 8GB Hynix SODIMM's perfectly 🙂

Thank you very much for your reply Hmscott, i just purchased 2 x 8 gb of the same model on ebay. 🙂

Ram installed 24gb now seems to work fine.

Protervis, glad to hear it worked out 🙂

Now you can disable Windows pagefile and hibernate, and save a bunch of space on your C drive.

Set pagefile to 0 size, and start a cmd windows As Administrator and run

powercfg /hibernate off

Then reboot and you should get back about 30GB on your C drive.

Just make sure you watch memory usage so you don't go past 24GB 🙂

That's really useful, thanks again for the tip! 🙂

So I decided to upgrade the ram on my 750JW. Figured I'd remove the pre-installed two 4gb Samsung sticks and go for 16GB G.Skill Ripjaws DDR3 2133MHz.

Such a headache to open the laptop to get to the two slots under the keyboard, got aluminium cuts on my fingers along the way. Anyway after two hours of taking apart and putting back together, losing screws, working out which one goes where it was complete.

XTU scores before and after the ram upgrade, was 664 and is now 837. Nice little jump with no other system setting changes. I haven't had a chance to run any other tests but no doubt this will suffice for a while. From all the reading I have done, as I understand, the max I can go is 16gb with 2133Mhz SO-DIMMs.

If so the next time around, I may need to swap out for 1866Mhz (not sure if 32gb works). So far so good though and well worth upgrading the ram purely on the basis of getting the most out of this gaming machine.
