Increasing RAM Question for Laptop Question

Have an old asus laptop. Its asus u45jc-a1.


I3 processor with 4gb ram. It has 7200rpm 500gb hard drive but i replaced it with a samsung 256gb ssd.


Laptop is lagging always when opening many chrome windows. I know the laptop is older processor i3... but i like this laptop mainly b/c its 14.1 size and not that big and not too small.


I want to upgrade the ram and from what i check online, my laptop can do 8gb. Is my laptop 4gb but its 2gb sticks each? Im not sure about this.


If i were to upgrade and want 8gb ram, i have to buy 8gb ram total thus two 4gb ram sticks correct because i have 2 slots available?


Do i need to make sure the ram is compatible with laptop only?


Im checking amazon so is this the one im going to need?


Amazon.com: Crucial 8GB Single DDR3 1600 MT/s (PC3-12800) CL11 SODIMM 204-Pin 1.35V/1.5V Notebook Memory CT102464BF160B: Computers & Accessories


But i have to get two 4gb sticks instead of one 8gb stick?


I dont want to buy some ram and find out its not compatible with my laptop.

 

I find conflicting reports on the max memory for your laptop. But the Asus spec sheet says max is 4gb.

http://www.asus.com/Notebooks_Ultrabooks/U45Jc/specifications/

Also this memory specific site agrees.

The difference is between 4GB OEM and upgrade maximum of 8GB. The memory for this system is cheap. I suggest you upgrade to maximum immediately for a slightly more efficient performance.

 

Asus U45JC A1 Memory
System Memory
Standard Memory: 4096 MB (2 x 2 GB)
Maximum Memory: 4 GB
Expansion Sockets: 2
Memory Comments: PC3-10600 1066Mhz DDR3 SDRAM

 

Does this mean i could get 8gb ram or not? The above post i can or cant?

 

Does this mean the original one i posted won't work because its 1600 mhz?



So would this one work then?

I see its mainly for mac but my laptop is asus.

 

To me it looks like you won't be able to have more than 4gb max. If I'm wrong, your best chance is this..

Are you sure? Someone mentioned i could do 8gb max... so 4gb on each stick or am i wrong here?

 

It would have to be 4gb on each stick for sure. However, it wouldn't surprise me if it won't use it. From what I can see, 4gb is max. Personally I'd contact Asus directly, email or phone, and ask before I ordered.

 

My Lenovo u300s also says 4 gb max. Didn't stop me from putting 8 gb in though & works fine. It was he'll getting und ER the keyboard though. Skip the call, try it. If it doesn't work return the ram. If you are using 32 bit Windows don't bother. It can only use 3.5 gb.

To me it would be easier to verify with a few minutes on the phone vs ordering ram, installing it, finding out it doesn't work, then having to go through the return process. But that's just me

 

Agreed. There is conflicting information here, so the best way to get decisive information is to contact the manufacturer. Provided you speak with somebody who knows for sure and not just a phone rep that just reads the same info that you did.

On the other hand, i can't tell you how many times company information has been out-of-date, or just wrong due to typo etc. and not corrected. This could possibly one of those occasions? Please let us know what you find out.

 

Yes, sometimes Crucial and other vendors post wrong information on upgrades. Case in point, I own a Dell Latitude E5510. Which takes DDR3 RAM. And Crucial listed PC3 12800 memory as recommended. This Dell will not run with it, it is finicky about what RAM does run. I removed my factory installed RAM and checked it, it said PC3 10800. I installed the Crucial RAM in my HP ProBook 4430s and no issues. I bought another stick of 4GB PC3 10800 RAM for the Dell, no issues and it went from 2 GB to 5GB RAM. Check and verify.

 

ASUS rep's answer will not differ from ASUS official info. The just copy-talk what is on the official site, nothing more. Just finally buy any 1333MHz RAM and that's it. The only reason from working fine would be BIOS limitation o purpose and nobody knows if it presents or not. I would buy for sure... 1.5 years ago when it was even cheaper.

 

Few notebook manufacturers go to the trouble of coding a RAM limit into the BIOS. However, many notebook manufacturers don't both to check and certify that their products will work with more RAM than they are shipped with. This policy is understandable if the next size of module is rare and expensive, which might have been the case with 4GB SODIMMs in 2010.

My method for determining the RAM limit is to look at the CPU and chipset (for older notebooks which don't have the memory controller in the CPU). The version of this notebook reviewed here had an i3-370M which Intel says can address 8GB. Therefore, subject to the proviso about a limit in the BIOS, 4GB modules supporting 800MHz / 1066MHz will work.

Yeap, What John said, I was just too lazy to write all that Except I know stories where 1066 RAM did not work for some reason in laptops which need 1066 RAM (surprise) so I suggest to buy 1333 one because it is backwards compatible with 1066.

 

I'm going to agree with the two posters above; provided you can access both RAM slots, 4GB x2 should work. I have the same-gen Intel processor as you in my notebook, a circa-2010 Core i5 (basically an i3 with variable clock speed) and have been running 8GB since I bought it (4GB x 2). Use DDR3-1333. The memory controller for these CPU's is located on the CPU itself and not on the Northbridge like Intel CPU's of the past; as John said, unless ASUS coded a memory limit into the BIOS, there should be no issue.

 

Asus tends not to do that and you can even go over the RAM limit provided the CPU controller can handle it. i.e. even first gen i7s could do 16 GB even though they were rated at 8 GB. 8 GB should fit just fine.
