Q. I am looking at buying either an Acer Aspire One 722 or 725. Do either the AO722 and AO725 support 8GB of RAM? and if so, what is a memory module that is FOR SURE supported? -Carly
A. Hi Carly, here are answers to both your questions:
Yes, the AO722 and AO725 support 8GB of memory!
Here is a nice Corsair 8GB memory module that is confirmed to work in the AO722/AO725 and right now it is only about $39.50 with free shipping and a lifetime warranty 
Notes:
- Here is additional third party verification of AO725 compatibility
- Verification of AO722 compatibility
- More verification that the AO725 supports 8GB of RAM (just peruse the comments )
- Make sure you are using a 64bit operating system, otherwise a 32 bit OS will only utilize part of the memory (but your BIOS will still verify that 8GB is recognized)
- Here is my memory upgrade tutorial for the AO722 & Ao725
For being such bargain laptops (generally available from $200-$300) I give them 5/5 stars for 8GB RAM compatibility and ease of upgrading!
Acer Aspire One AO722/AO725 8GB memory upgrade, recommended RAM? [ANSWER],
JDH,
Very helpful blog. I raced out and bought the Crucial 8GB (now 30.99 at AMZN), but my WEI is still pegged at 3.2, altho installed RAM sez 8.0GB (7.7 usable)
What gives? Should I stick with a 4GB?
I have a AO725 with AMD C-70 64-bit Win 8
Please advise.
Thanks
SB
PS. I did forget to remove the battery when I installed the 8GB but it is recognized nonetheless – just doesn’t seem to be a mind-blowing difference
Hi SB,
Thank you for your comment. I apologize for the delay in responding!
To answer your question, the ‘overall’ WEI base score will always be pegged at whatever your lowest individual WEI score is. So in this instance your 3.2 is probably from the CPU or the Graphics, rather than the memory.
If that is true in your case, where some other component is limiting your score, then I would definitely stick with the 8GB of memory as that is a great upgrade!
If for some reason the Memory (RAM) portion of your WEI is actually a 3.2 then something would seem to be amiss, as I believe a score of 4.9 or so would be typical for the AO722?
I hope this information has been helpful SB and please keep us posted on your experiences!
Best regards,

Hi,
Thank you for info and I’d like to confirm that CMSO8GX3M1A1333C9 is compatible with Acer AO725-0826. After replacing original 2GB stick with 8GB CMSO8GX3M1A1333C9 windows experience Index for memory improved from 4.9 to 5.1.

Hi V.C.,
The price is also very reasonable and I like that it is currently available via Amazon Prime for free shipping!
Thank you for your awesome comment! I appreciate you taking the time to confirm compatibility for other readers, it will be very helpful for people who want to use 8GB of nice memory with that cool laptop.
Have a great week and thanks again!

Is there a BIOS issue with 8B DIM for AO722?
I have standby/wakeup problem.
Thanks
Hi Rey,
Thank you for your comment. I am not aware on any BIOS issue related to the AO722 and 8GB of RAM. Have you tried the very latest BIOS? Do you have any other 8GB SODIMMs available to test on?
Sorry to not be of more help!
Best regards,

Hi J.D.H, my question is i want to buy te ao725-0478. Can i upgrade the processor and memory???for what processor and memory???
thanks and great job with the site!!!!
Hi Daniel,
but unfortunately you cannot upgrade the CPU 
.
Thank you for your question! You can upgrade the memory
Here are complete instructions for upgrading the memory. The photos are of an AO722 but they apply to the AO725 a well.
If your prospective AO725 has 2GB RAM then I would recommend upgrading to 4GB or 8GB depending on your budget. Likewise if you REALLY want to improve responsiveness, in addition to RAM, I highly recommend investing in a SSD for your AO725, it makes a huge difference in snappiness* compared to the default hard drive.
*NOTE CPU intensive tasks will not be improved by a SSD, but these things will: boot time, suspend/resume, application load times, anything that stresses the hard drive etc.
I have had good success with the following brands of SSD: Intel, Samsung, and Crucial. (OCZ brand too, but I have concerns about their financial viability as a company)
Please let me know if you have additional questions Daniel!
Best regards,
-JD
