Actually how dual channel works me myself also not sure geh...haha...anyone could explain??

Nothing to do with FSB, thats for your processor.
But your effective RAM frequency is simply 667 Mhz.

Do laptops use that kinda RAM??? I thought all laptops use 1 stick of RAM, and is very different from desktop RAM...?

well.. i'm not expert in RAMs.. but i know a little bit la..
for dual channels actually it is system that make ur system faster.. 64bit X 2...
dual channel smth like we call we doing 2 things at the same time..

if u have 1 512mb onli, when u active task A, then ur prossecor will call ur ram start work.. then at the same time, ur active task B, then the prossecor will take the rest of the ram that left after use by task A to work.. means that 2 task r sharing 1 RAM...

on dual channel.. is u have to plug in 2 ram module.. so apply same example.. task A will use RAM A*, task B will use RAM B*... although there have alot memory left by RAM A*.. results each ram wont soo burden and work fast..

let us apply a very simple exmple,
if i plug 1x1gb 667Mhz ram into my laptop.. it will abit low efficiency than i plug 2x512mb 667Mhz although the memory size r the same for both situation.. this is b'cuz dual channel.. i can say that almost same as dual core(the concept)

about the "FSB" Front Side Bus... i can said that it like the road in the computer system.. erm.... or we can said that it is the connection between cpu and memory.. it wont duplicate with Dual core system or dual channel.. it fix..
For example.. ur prossecor only support 533Mhz, ur motherboard 800Mhz and ur RAM 667Mhz.. ur computer onli can run max 533Mhz FSB onli.. b'cuz it needs a good combination between ram, cpu & mother board..

some of u may hear ddr-667... ddr2-800.. for ddr2-800, its actually is running at 800Mhz FSB.. normally we will buy value ram.. thats 400Mhz, 533Mhz, or 667Mhz.. but there are othe hyper X memory that provide high performance memory.. normally their bus speed is at least 800Mhz.. some of then even 1066Mhz, that manage to push up the C2D power.. but of cuz.. those RAM's price also higher than value RAM..

for the laptop case.. i suggest u put in 2x512mb with 667Mhz.. thats the best system config.. or u can try 2x1gb(but costly.. rm800++).. 1 more thing, normally there is 2 slots in laptop.. u onli can do 2x combination.. immposible to put in 4x256mb..

this is all i know.. correct me if i'm wrong~

This means that let's say i have a 2x512 i m doing task A n B at the same time? As in Task A will be using one piece of 512 and Task B another piece of 512??

This makes it better than using 1 piece of 1gb and sharing it??

Now I am having 2 x 512 MB pc 3200...If I add 2 x 512 MB pc3200 so total is 4x512MB pc3200...Will it increase my system performance...My friend said tat 1G and 2 G no much different le

dude..there are differences...if not people will buy 1GB

this is the concept .
like highway got 128 lane better than 64 lane when in heavy traffic .
maybe your friend not yet try some 'memory extensive' program .

yup.. it sure will increase ur system performance.. but have to depends what u doing with it..

if u onli doing some normal task.. like surfing net.. listen music.. movies.. then actuall 512 is enough.. but u plan to play some games.. of cuz, its good to have 1g.. but for those who work as programmer or doing hardcore graphic thats need alot multitasking.. 2G or even 4G will onli enough.. if not u'll feel nth with 2G ram...

yup.. thats what i'm trying to said~

Okie...now I understand...thnx a lot

Yeap..I am currently using a 512 cause last time i was noob in computers...even when the prices of RAMS were stul low like bout RM170.. Now iw ant to add another piece of 512..l0l..and the price is way up...I use to play games n listen to songs..but now... I MULTITASK...haha

512MB ddr2 667MHz Ram.... Kingston and Corsair, which brand is better? Performance wise a lot different? Fair enuff for the price different? Where can i get good offer?

Kingston and Acer you can have lifetime warranty... what do you think??

just brought 2 unit of Corsair 512MB ddr2 667MHz ram. When i plug in both ram, my r60 failed to power on.

i will only power on when i mix 1 unit of corsair with my existing kingston 256MB 667MHz ram or just by 1 corsair itself.

wonder why i cant power on with both corsair ram?

help!!!!!!

one thing i don't understand bout rams is latency and r60??

sorry superlfc ... thisis nothing to do with your question but i cant find anywhere else that can help me understand latency and those r60 stuffs...

Ram experts I need your help.

I would like to know whether these 2 products can be ran at dual channel on my laptop.

Currently, I have this installed, a 1GB Samsung DDR2 PC5300 667MHz SO-dimm ram.

http://www.samsung.com/products/semiconduc...470T2953CZ3.htm

But I can't seem to find the same one at shops.

Maybe of trying Kingston.

http://www.samsung.com/products/semiconduc...470T2953CZ3.htm

Do you guys think they will work fine together?

Different rams can work 2gether... No worries

Thanks, hope to hear from more people. thanks.

haha...this question was asked before
