well,i contacted acer to ask about my acer aspire g7750 about upgrading my ram and gpu, and guess what i just got smacked in the face. it turns out that according to acer i cannot upgrade my ram to 12gb or 16gb because the ram slots are locked on 2gb max each :( and they dont want to tell me if can upgrade my gpu,because of compatibility issues and crap. NEVER BUY A PREBUILT PRODUCT FROM ACER IF YOU WANT TO UPGRADE IT IN THE FUTURE. any suggestions of what i should do now any ways around this? i spent alot of money on this rig and i just got screwed in two different components, cant imagine what they dont let you do to cpu's anyway any help would be appreciated :(

When you bought the product, did you explicitly state to the sales representative from ACER, or do you have the link to the documentation that said the device could be upgraded sometime, maybe 5 years in the future?


In other words. Are you complaining because they misled you or are you ranting because you made a false assumption?

Is this the computer you are talking about? Its nearly 6 years old:

http://www.cnet.com/products/acer-aspire-predator-g7750-u222/

That said if that is your computer, It has 6 RAM slots, so while they may be limited to 2GB per slot, you can get to 12gb at least.

It also has 3 PCIe slots, any current PCIe GPU should work fine in there.

The processor is about as fast as you can get in LGA1366 so unfortunately thats as far as you're going to go there.

Youre kind of at the point of diminishing returns, while you can upgrade the memory and GPU you are limited by that motherboard and processor, sorry to be the bearer of bad news.

well that's what i thought about the ram but they said each slot is 2gb each and apparently the third slot is blocked off according to the acer chat agents.and i asked about upgrading my gpu but they were like its highly unlikely it would work and would have compatibility issues and wouldn't work properly, i just spend alot of money on it and i am upset that according to the acer people i can do nothing with it even though i should be able too just like you said, i dont know if this is false information because obviously acer dont want you to upgrade the pc so i dont know if should buy 12gb of ram otherwise its a waste of money and im not sure if i should splash out 300 pounds on a gpu because that's huge risk according to acer.

How did you just spend a lot of money on a 6 year old PC? Can you return it? It sounds like you got hosed. That computer these days is worth $200 US tops as a "working PC". It will run current games, but only just and fairly poorly.

That specific model all of those slots do work according to the specs visible online, I don't know why they would tell you they don't. You can easily see if they work by moving your memory to different slots and seeing if it boots. Its possible someone pulled the memory beyond 4gb out and used it elsewhere. That PC came with 12gb standard.

As for the GPU not working, there is a chance of issues, but most likely it WOULD work. I wouldn't buy a crazy expensive one, but something like a R9 380 or GTX 970 is reasonable if a little overpowered.

Find the cpu support list for it. Find out if it supports the server xeon 5xxx series cpus or not.
If it does support "westmere" cpus. Many have been pulled from servers or were spares that were never used.
Look on amazon.
There is a 6 core westmere.
You will need the latest bios to run it.

It's a totally different cpu core so make sure the board supports it first.

The memory is triple channel not dual channel. So it's three 2gb sticks for a total of 6gb.

6gb is fine for gaming. Finding a triple channel kit is not easy today. A 4 stick kit is expensive. Then 1 stick is wasted too. (To get 3 matching sticks.)

well, i brought this computer a long time ago when it was expensive and good for the time i then stopped playing on the pc for a while and now im back and the guy at acer told me that there was different variants of the pc sold..yeh i know, i think he didn't know what he was talking about as i have never seen another variant other than the 12gb g7750. anyway he told me that the 4gb version was sold which was mine and because its 4gb they blocked out the 3rd channel so people couldnt stick in there own ram for cheaper. because people would have brought the 4gb version and im guessing they would have put in 12gb worth for a cheaper price,i dunno but they obviously didnt want people adding ram.and yeh i was thinking of getting a r9 390 because it is better and the same price as a gtx 970.hope this makes sense. but this is why im stuck because in the manual it says i can have 12gb of ram but 2 acer people have told me otherwise. but they said they have barely information on the pc.any suggestions thanks?

well thats another problem because i dont know the motherboards name. or brand and neither did acer the cpu support list is no where to be found according to acer and yeh i was browsing for 12gb of 1066mhz triple channel ram but barely anything appeared.but i can buy i think online the actual ram that was sold with this pc online http://www.amazon.co.uk/Memory-Aspire-Predator-Destroyer-Arch/dp/B00A84Z6UM i beieve it is this...not too sure,any help if you could find anything like i mentioned earlier in this reply would be helpful,thanks

The first thing I would do is if the slots are physically open I would put the memory you have into the slots and see if the PC boots. If it doesn't then you have your answer as to whether or not the slots work.

If they do work then buy the exact same type of memory.

As for need4speeds suggestion, that is not going to work for you, the board in that PC is proprietary, and it does not support the processors he suggested, nor is there a BIOS update available to support them. You have the fastest processor it will run.

Finally yes the R9 390 will work, it will be a bottleneck on the system. You can buy that card now and then use it for your next build. I wouldn't throw any other money on that PC (other than the memory IF you can get it cheap), its very outdated and if your goal is to play newer games its only going to get worse.

Upgrading the memory will do little for gaming. Many games like Fallout4 say they need 8gb when 4 or 6 still works.

http://www.amazon.com/Intel-3-46Ghz-LGA1366-Westmere-Processor/dp/B00MVORFH4/ref=sr_1_1?s=pc&ie=UTF8&qid=1450818950&sr=1-1&keywords=LGA1366+3.46ghz

Intel Xeon W3690 3.46Ghz 12MB LGA1366 Hex Core Westmere

If you have 3 empty memory slots now, you would need three of the 2gb memory sticks for a total of 6.
They go in groups of three since it's triple channel.

Open the case and see what memory sticks you have now. Look at the board and find the model number.

They offered the i7-960 in that computer. The i7-960 is westmere but it's the W3XXX series. It's down to if the SERVER X5XXX works or not. Most boards that have 6 memory slots work with the server cpus. The ones with only 3 memory slots only support the i5's, i7's and W3XXX cpus.

http://userguides.manualonpdf.com/ebook_Acer_Aspire/acer_aspire_predator_g7750.pdf

Because of the higher stock speed, 6 cores, i know it's $300 but it's better than overclocking the 2.4 and 2.8ghz ones to save money.

It's worth some effort since you can reuse your board, memory, cooler, and not do a os reinstall.
If you get it working with a 6 core at 3.46ghz that is fast enough for a new R9-390x or 980ti.

It will take some time to search what others did with those systems, and look up info on the board.

Hi again, i did some search and I found the following:

Memory: fill all the slots with 2 GB and you ill ok for gaming.

CPU: the main-board support Intel i7 processors in 1366 package (up to 1366 MHz FSB), that means you can install the Core i7-960 or even the Core i7-975 Extreme Edition. it has chipset Intel X58.

VGA: there is no limitation, support the ultimate VGA cards (R9 390X / GTX 980ti)

basically my motherboard has 3 blue sockets for memory and 3 orange so in the blue section i can fill that with 6gb and the orange with another 6gb and then i will have a total of 12gb but if i the third section on each is blocked off then i would have 8gb of ram in total. i have just went on cpu z and it does show my cpu to be in a 1366 socket but the need4speed guy says one was not 1366 and one was another socket and that determines where ever my computer is three channel or dual channel.but what im going to do is swap the ram around to see if the third channel is usable and if not buy 4gb of ram dual channel times by two for a total of 8gb.but now i also need to know if need4speed is telling me accurate information about this socket thing.

The board is LGA1366 , so the i7 960 or i7 975extreme are the fastest processors. If you can find them those would be the only processors you can use. Upgrading to 8gb and a good gpu will give you enough to play most every game decently well today and in the future.

All is not lost. I wouldn't dump a ton of money into it but like I said the GPU you can re-use in your next build, and 4 more gb of ram should not cost you too much.

well rogue i am not going to bother with a new cpu like you said i shouldnt dump too much money on the build because it isnt completely dead i can still stick in some ram and a gpu and all should be fine until my next build.thanks

Yes i seen a pic with the same MB model number you had and it showed a socket 1156 board. A different one showed a socket 1366 board. BOTH HAD THE SAME MODEL NUMBER.

You then said it's 2 mem sticks, now it's 3 blue ones and 3 orange ones. Socket 1156 is dual channel and 1366 is triple channel. So you can only add a set of three memory sticks.

Most boards work with i5, i7 and the workstation Xeons like the W3690. Most but not all work with the E and X ones and the ones with 5XXX like the X5650 are made for multi cpu socket servers so this is why they sometimes don't work on single socket boards.

With no actual cpu support list, no one can say 100% for sure what will work. Even the i7-960 is the newer 32nm cpu and yours is the older 45nm one.
