Your acer has a max of 16GB of memory so if you've exceeded that it could be the problem. You could have misread the specs, The processor will support up to 64GB but if you read closely the motherboard only supports to 16GB, if not swap it with another memory chip if you have one and if the computer does not see it too you have a bad slot on the motherboard or maybe a bad memory stick out of box. The only other thing is maybe to clean the chip contacts and the slot.

It shouldn't matter too much, but the motherboard might be rather twitchy about what memory timings are being used - ideally, the new RAM stick needs to be the same voltage, speed, and timings as the one currently in it.

So if it has, say, 8GB DDR3-1600 (11-11-11) in it, then that's what you should install with it. You can find out what you've got exactly by using CPU-z:


Install this and then go to the SPD tab, where you can see the details for each RAM stick you've got in the motherboard.

That program says I have 16gb of memory but my task manager says that I have 8 gb of memory, I don't know why

One last request: could you take screenshots of the CPU, Mainboard, and SPD tabs in CPU-Z. This is ascertain the exact specification of your Acer and what DDR3 type is should be using.

Ah, there’s your problem: one stick is DDR3 while the other is DDR3L - the latter has two voltage stages (1.35 and 1.5V), whereas original DDR3 just had the one (1.5V). The Core i7-6700 only supports DDR3L or DDR4; the DDR3 stick isn’t supported.

No, it's not - the motherboard recognizes it's there, but the CPU's internal memory controller has no support for it. DDR3L or DDR4 only:

Although the CPU can support DDR4, the motherboard in the Aspire T3-710 only has slots for DDR3L. It's actually cheaper to buy a pair of 8GB DDR3L sticks than it is to buy a single one:


The one guarantee you have with getting a kit is that the manufacturer will have checked that they work fine together, as a pair.

Some of the big specialist suppliers of ram have online checkers that will identify the type of ram that is installed and bring up the compatible sticks that they can supply. It's not worth crossing your fingers and ordering ram at a bargain price. Other than that you could remove the stick you want to duplicate, note carefully all the info printed on it and look online for a match.
