My wife has an Acer Z5710 all in one type PC and I want to boost the RAM a bit. It has 4gb (2 x 2gb) just now and I want to buy another 2 x 2gb to double it up.

Can anyone tell me which type of RAM I have to get by looking at these? I know it's DDR3 but what speed? Any recommendations/bargains greatly appreciated.

Open it and see whether it can take 2 more DIMMS.

You need 1333, but I suspect the timings won't necessarily match. The BIOS should be able to sort that out for you.

Sweet. It says it has 4 slots and is using 1 and 3 just now.

Thank mate, that's me A for away :)
 
The RAM that you currently have is:
DDR3 1333MHz CL9 1.5V
To get to 1333MHz, simply take the DRAM frequency of 664.9 and multiply it by 2 = 1329.8MHz.

So try and get memory with the same speed (1333MHz), clock latency (CL9) and voltage (1.5V).

If you get DDR3 1600MHz CL9 1.5V or DDR3 1600MHz CL10 1.5V, then your motherboard should downclock it to 1333MHz to work with your existing RAM modules.
DDR3 1600MHz CL10 modules actually have lower clock latencies than DDR3 1333MHz CL9, so DDR3 1600MHz CL10 should be fine:
CL10 / 1600MHz * 1300MHz = CL8.3 :)

Thanks for that. I was going to buy a couple of these, does that look like a good deal? (got some ebucks to spend)
 
Yeah, those will be fine. Luckily your AIO uses desktop RAM, not mobile memory chips like newer ones do.

Typically, yes, but it depends on corresponding JEDEC table @666MHz. It can be a surprise. :)

I also checked. I am also using DDR3 RAM (https://mybroadband.co.za/forum/threads/ram-question.670280/) I think that must be the issue.
