Asus A8Js Memory Upgrade

Hey there,

I am relatively uneducated concerning upgrading memory but i do know enough that the wrong kind wont work in my laptop at all. I have a stock A8Js and according to system properties in my control panel I'm running 977MHz 1.00 GB of RAM. (According to this site's review of the A8Js, it's supposed to be 667 MHz DDR2?)

I am looking to buy another stick of 1 GB RAM to accompany what i already have in there. I would like to know what kind of ram to get / the speed of it / how does something like "PC2 5300" affect my buying decision (what does it even mean?)

Thanks,
Wai Jun

 

what you are using is a ddr2 sodimm runnning 667 bus speed. check newegg.

 

Its almost certain that the memory is running at either 533 MHz or 667 MHz. 533 MHz RAm is sometimes reffered to as PC2 4200/4300 and 667 MHz sometimes as PC2 5300/5400. To get the PC number, you can multiply the effective frequency by 8. Then round either up or down to the nearest hundred.

Your notebook will accept both frequencies of RAM. The 997 MHz you reported in your post is likely to be the processor frequency, so disregard that. The RAm you will be needing is 200 pin, SODIMM RAM. You can find alot of it at newegg.com. The price for another 1 GB module is around $60, and some are cheaper. Its normally better to go wih RAm from reputable manufacturers, like Corsair, Kingston, G. Skill, OCZ and Crucial, but normally, cheaper branded RAm will also work.

When choosing your frequency, go with which ever is cheaper, as there is practically no speed difference between 533 MHz and 667 MHz RAM. Another thing worth mentioning is that you should check and make sure you don't have two modules already installed. Use a program like CPU-Z to check this. It will tell you what density of RAM is installed in each of the two slots.

 

Thanks! that answered all of my questions

Edit

I just ordered a stick of GSkill PC2 5300 and i was wondering...
Is ram one of those simply plug and play hardware upgrades or are there ways to optimize the performance? (like a bios upgrade or something complicated like that)

 

5 bolts largest panel on bottom.

ram goes into slot above the other dimm

you put it in at 45 degree angle then push it down flat the metal things hold in in

automatically works

do it with power off and battery out.

 

As far as optimizing the performance of your new sticks, usually it's not possible because the BIOS does not allow it (many NB BIOS do not even offer the option) . Also OC introduces more heat to the nb, which can reduce battery life and wear on your components. I wouldn't recommend it.

 

The 977 MHz thing is most likely you current CPU clockspeed, which is downclocked one way or another.
