Hei... where i can see my spesifik pc on my notebook?

I checked for Acer 4740 and I found the Acer Aspire 4740. This laptop should be able to use the following memory:

Your computer has two slots for memory. It's recommended that you have matched memory for best performance. In other words, both memory sticks should be the same (both sticks 1GB at 8500, or both 2GB at 8500, or both 4GB at 10600, both 2GB at 10600, etc.) 8500 is slower than 10600. The 10600 should operate at 8500 but it doesn't always happen that way.

How do you know your VGA is damaged? If you remove the 2GB 10600 memory does the VGA work again?

thank's vry much, i think that my VGA. because My LCD screen Fully of vertical red line. then when i restarted it again that's no display <<... hey after 4 day not using that back to normally.. i don't know why? i am not master just wanna be? hey that's amazing site.. thanks

Glad to hear the computer is working again. Computers can be very strange and do things for no apparent reason. One other thing to watch out for is heat. That new 2GB 10600 might be getting hotter than the original 1GB 8500 and heat can cause problems. There's a free tool called SPECCY that can monitor your temperatures for CPU, Graphics and hard drive (along with a lot more information about your computer.)

That new 2GB 10600 might be getting hotter than the original 1GB 8500 and heat can cause problems. << but the site said.. can upgrade to 8gb. (Why Must?keep on 1gb):)

DDR3 PC3-10600 & DDR3 PC3-8500 are not the same. If used together, both will operate at the slower speed & as 64-bit, not 128-bit (i.e., dual-channel mode). If the voltage & timing are not the same, they may not function at all together, but will function individually.
