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.

This is getting somewhat long ... the short story is ... if you are upgrading RAM ... best to find out exactly what you are running now and if you are just adding some additional memory ... double check that the RAM you are adding has a mode that exactly matches your current RAM.

Too many people who should know better in this forum are blindly recommending buy something better/faster speed it will be compatible.

In many cases this is not true and sometimes the advice being given here is not helping people.

Just my opinion.

yes, that's exactly what i've just learned today. please bear with me. i am new in many things. i also just learned that g75 is now available in my country. that's two whole months late 😕

A 16GB kit (8GBx2), 204-pin SODIMM, CL11, DDR3 PC3-12800 memory module: http://www.crucial.com/uk/store/partspecs.aspx?IMODULE=CT2KIT102464BF160B

That is why I asked the exact modules, to see what will work. And after that we got something that does not. I think it is very good info.

I also gave some general info about how RAM might work.

itll fit, though work dont know

1600, CL 11. Should work just fine.

I just noticed that the built in 8GB of RAM is composed of "ELPIDA J4208BBBG-GN-F" chips.

In a web search, these show up as 1333MHz chips.
So as I understand it we should only put in 1333MHz RAM into the rest of the sockets because
even if we put in 1600MHz or the mythical 1866MHz chips, the system will restrict itself to 1333MHz
base on earlier comments.

That being said is there 1 or 2 sockets on the hidden side of the motherboard? None of the photos
I have seen clearly show this.

The only reason I mention this is I am ordering extra RAM, another 16 GB composed of two 1x8GB.
I went ahead and ordered the 1600MHz version but now realize it need not have been.

I will post more before and after info and photos at a later time of the upgrades I am doing.

@metgen, if you're referring to my post here, those are additional ram that i bought separately (kingston valueram CL11 1600Mhz), NOT the stock ram that comes with my g55. to be safe, use hwinfo and find out what stock ram you have. then buy the matching ones.

i have posted my combination here, yours might be different.

You guys are over thinking this way to much.

The stock ram is DDR3 1600. Its the standard now for laptops. Get any new laptop even the $450 cheap ones they run DDR3 1600. Hell a $450 Toshiba had the same ram as my $1,000 Samsung Chrons7.


Just buy DDR3 1600 and slap it in. Domnt buy anything with Value in the name. Stick to the name brands.

All your memory does not have to be the same. 2 stacks for channel a and 2 for b need to be the same. IF your memory runs at lower timings then the stock ram the bios will automatically adjust the timeings. Just dont get some super high voltage ram and you will be good. Just walk into microcenter. Buy 2 sticks of DDR3 1600 and stick them in and its done. 4 pages is to much for this and we haven't even talked about Intel Flex Memory Technology.

Sorry do not agree ... need to find matching RAM ... need to check exactly what is in current system and match. Use HWINFO64 to double check.

If you buy stuff that is difrferent ... its a compromise ... it "may work" but ... may cause minor or major anomalies that can be prevented by double checking.

I'm having trouble following this thread as half of it is complete jargin to me, despite SOME knowledge of IT/computer stuff...

Here's what I need help with: I have the G75VW-BBK5. I have not added any RAM, I have been using an SSD drive and it flies with that. Recently I've had trouble with the hibernation feature in windows, sometimes after using demanding software like Photoshop and hibernating, it can't seem to system resume, so I have to clear the cache and go from startup. I'm pretty sure (correct me if I'm wrong) that windows stores all the hibernation junk (for lack of a better term) on the RAM.

SO: I want to expand my RAM. I don't know that I want to boost it to the maximum, BUT I would like help finding the most reliable/cost-effective and quality parts if I'm going to do it. Do I need to install 2 sticks (fill both empty slots) in order for it to work? Can anyone recommend a specific brand/model of RAM? (Link me?) If it helps I'm in N. Am. so it'd need to be someone that ships here not over in the UK or anything...

My memory (according to that HWinfo thing) is Hyundai part # HMT351S6CFR8C-PB if that helps?
