Question: how much ram does it have
Document: Now to be fair it may be entirely me, and comes down to personal preferenceI did download a program called Classic Shell that adds a Start button to Win 8 and still maintains the Metro interface. It really make the windows 8 platform fun to use. I just installed a 4 gig ram module, and did not notice much improvement, but for less than 20 bucks you cannot go wrong. I did put in a 16gb SDHC card and used the windows ready boost, there was a noticeable speed difference.
Is not so fast than appears. Provably i must install more ram to increase the potencial of this notebook because if i install more softwares it going to be really slow
The ram can be upgraded to be twice faster than a mini, this one has hdmi, which i will be using alot, i like the extra better features, something to think about
If you are going for a netbook, go for the extra ram (2GB)... Windows 7 and 8 need at least 1GB to run the OS, so you need at least 2 to make it work smoothly...
"for example I was going to replace my 2 GB DDR3 memory to 4GB as my netbook was/ is too slow and almost dies 10 times during my video chat with my students." or doing anything but typing a text!! !First customer service didn't know" there is just 1 Slot for ram and was telling me get 2*2GB!! !I told him" it is just one slot memory!"
This is a very slow computer. I was intending to take it back and forth to work, for travel, etc for easy access to email, internet, etc. It's just so slow that it aggravates me more than anything else. I also thought I would be able to get used to windows 8. After having it for a month I've decided to sell it on Craigslist instead of upgrading the ram. Will be purchasing a MacBook air for my needs.
This laptop was slow as hell...I had shutdowns,not connecting to WiFi..I got sick of itI installed my Intel SSD.4GB ram,Windows 7 64bit.Intel 6300 wireless card :) ! (with extra antenna):)5 stars! the website had the driver for AMD "VGA_AMD_8.981.0.0000_W7x64W7x86_A" notice 8.981... not 8.982 ( windows 8 ).After that.
Bought this and right out of the box it didn't work well. Connection to the internet is very sporadic. Replaced 2GB ram with 4GB of ram. Connects to my router but it can't find web pages. Error code says it continuously is searching for multiple routers or access points. Have tried everything I can think of to fix, but to no avail. I'm thinking of returning it. A netbook should be able to do one thing very well - surf the web.
I also have it on the high performance option because I am never more than 50 ft from the charger. It's lightweight and looks great as well. The USB 3.0 itself is unbelievable. I grabbed a 16G USB 3.0 Flashdrive for cheap and transferred 10.2 GB in around 5 minutes. The biggest thing though, was my purchase of a new stick of 8GB Ram so I could get even more out of this little thing.
So this computer is limited to running only a few programs simultaneously with its AMD C-70 Processor running at a peak 1GHz. 2GB of ram/dram used to be extreme at one time but not anymore. 320GB of HDD is nice but again with todays programs needing large amounts of memory that 320GBs fills up quickly. My suggestion is to either spend some money for what you need to run some serious multitasking or simply upgrade what you have. I upgraded my ACER with a Crucial SSD and 8GB of ram.
Answer: Ali is correct.  Comes with 2GB but I expanded it to 4GB.
