Adding RAM to G75VW BBK5

[Loren]

I would like to add more RAM to my Best Buy G75. I wanted to add 4 new RAM modules, but have read on the forum that getting at the stock RAM will void the warranty as it is located under the keyboard. If I were to leave the stock RAM alone and add two 8 GB RAM modules with the same specs (1600 DDR3...) would it work? i.e. does it mess things up to have two 4 GB modules under the keyboard and two 8 GB modules in the easy to get to locations?

I have read that the reason 16 GB is the max is due to the version of Windows--that you have to run Windows 7 ultimate for the machine to use more than 16 GB. If that is true what amount of RAM can Windows 7 ultimate utilize? 24GB? 32GB??

If I were to replace the stock RAM and have four 8 GB modules could I successfully use a higher MHz than 1600 (1866)?

Also, if I made a "RAM disc" would the computer be able to access the info significantly faster than it would from a solid state hard drive? I am replacing the primary HD with a 256 GB Samsung 830 regardless of what I do with the RAM. I "fly" quite a bit with Microsoft FSX and X-plane 10. If I loaded the flight sim on the RAM disc along with a lot of the scenery data I use a lot it seems to me that this would be the best way to improve performance (frame rate, etc.) or am I wasting $$ expecting a RAM disc to be much faster than an SSD?

I look forward to your comments.

i agree with john_from_ohio, we need to find matching ram. if the system supports 1600Mhz, why should we run it at 1333Mhz when simple steps are enough to help prevent wrong purchase?

actually, i've bought diffferent ram (all DDR3 1600Mhz; all branded) after consulting related posts here. that's before people like c_man and john_from_ohio finally gave me a correct picture of what i should look for.

I have two 8g sticks of 1866mhz and it runs at full speed 933 you can only run 16g of 1866 meaning it has to be two 8g sticks only it cant be four slots of 1866. I dont know if they even sell 4g sticks of a 1866 but at the time when i bought my ram they didnt make 4g sticks of 1866. Each slot has its own power it gives out so it uses all four slots power in two slots to run the 1866 ram at max speed i have been running mine since the day my g75 came in the mail and i have never had any issues. I cant remember were i found the information on this but thats why i only have my specs and plus 16g is plenty for me i would have put 32g of 1866 but i will not run at full speed it has something to do with the power that is being distributed. But yes 16gb of 1866mhz ram will work flawlessly in your laptop anything higher will stay at stock speed so if 16g is not enough stick with the stock ram specs that came with your laptop and max it out to 24 or 32g but if you want the 1866 you will only get it at 16g two 8g sticks and it doesnt matter what slots you bave them in.

I may be late in replying to this thread but I'm currently running 24gb of RAM, the stock 8gb and an additional 16gb Corsair Vengeance
they are both reading 800mhz. The only thing I was concerned about is I believe the stock ram run on CL9 and the Corsair runs on CL10 but so far I haven't really noticed any difference between the two.
