The rule of thumb with RAM is to always buy matching pairs. So instead of buying one new stick of 1gb its a better idea to buy two of the same kind and replace the one that is currently in there.

Before you even think about doing this, head over to lenovo's website and make sure that the computer is compatible with 2gb(from the speed of the ram im assuming that it will, I don't know of many DDR2 computers that cant have 2gb.) you may also be able to get ram that is faster if it is compatible, The website will have all this info.

Can the LG Xnote RD405 laptop intially with 1gb RAM be upgraded to 4 gb using two 2gb RAM's ? Please help me by providing an answer clearly, Thanks in Advance.


Here is the memory specifications from LG.

Maximum Size: Each slot is 1024MB and can be expanded to 2048MB.
SO DIMM Type for Memory Expansion: DDR2 SDRAM SO-DIMM (256MB, 512MB, 1024MB)

It can take a maximum of 2 gigabytes of ram. It will take two 1 gb sticks. It uses DDR2 laptop ram. You need to check to see if you have one stick that has 1 gb or 2 sticks that have 512 mb each. That will tell you if you need to buy one or two sticks of ram at 1 gb each. You will be able to tell a difference going from one gb to two gb of ram. I think it would be worth the investment if you plan on using the computer for another year or more.

Why does memory upgrade for biostar k8m800-mam2 motherboard cause memory error beeps?


I would verify that the memory you're using is actually working properly.
Try to boot to the new stick and see if it works.
If not, it doesn't work.
If it does, you may need to replace the original stick with the same stick that you are trying to use now.
Use this site as a guide.

I want to upgrade my computer specs... hope you can help me.. CPU: intel core2 duo E4600 2.4Ghz/800Mhz/2mb L2 cache/65MOnm MOBO: elite 945GCT -M2/1333 (v1.0), 1945GC/C2D/1333MHZ/DDR2 667/PCI-E memory:...


If you are a "gamer" and you have 1GB of RAM, and you have Windows XP, you probably need more RAM.
If you are a "gamer" and you have 1GB of RAM, and you have Windows Vista or Windows 7, you DEFINITELY need more RAM.

Some motherboards support "dual-channel" mode, when you have 2 or 4 _IDENTICAL_ sticks of RAM. What happens is that each byte written to the RAM is "split" into 2 halves; one half is written to the 'A' stick of RAM, while, simultaneously, the other half is written to the 'B' stick of RAM. Obviously, this takes 4 "cycles" of the RAM, rather than taking 8 "cycles", if there was only one stick of RAM. So, your RAM seems to run at "double-speed".

So, when you buy more RAM, either try very hard to "match" your current 1GB stick of RAM, or purchase a "2GB dual-channel kit", or two "2GB dual-channel kits", to upgrade to 2GB (or 4GB) of RAM.

Could I use MacBook Pro 1G RAM (hynix 1GB 2Rx16 PC3-8500S-7-A1) to upgrade my T400 2G RAM to 3G?


Hello thx5,
It depends on how the 2GB in your T400 is currently configured. If the 2GB in there now is just one 2GB stick of RAM then yes you can add the other 1GB stick and then you will have 3GB of RAM installed. If your 2GB is two 1GB sticks of RAM (which is more likely to be the case) then the 1GB stick you have from your Macbook Pro isn't going to help.

Note: your laptop can handle up to 8GB of RAM via two 4GB sticks.

Hope this helps, if so please leave some good feedback. Thanks.

Problem with upgrading my acer extensa 5620z memory to 4GB


Hi there.
I recommend you get another stick of SODIMM to replace what seems to be the faulty stick.
If you are using XP or Vista X86 (32bit) then the system will only recognize 2.8 - 3GB of memory, only 64bit operating systems recognize the full 4GB.


Good luck ad thanks for using FixYa!!
