how to 0/C high performance memory ram?
need wat software ?

are you sure about this ?
i thought dual channel is something for memory controller to use 64 bit or 128 bit mode
here comes a problem of that explanation

Yes, dual channel uses 128bit. A single channel uses 64bit.
64x2 =128bit =dual channel.

If you run 3 x 256MB 533Mhz, you cannot run dual channel. It needs to be in a pair. ie 2 x 256MB 533Mhz or 4 x 256MB 533Mhz. Remember, dual channel gives an effective 128-bit wide data bus. So whether is 2x or 4x 256MB 533Mhz, you maximum FSB will still only be 1066MHZ.

oh okok...thnx a lot!!!!

What if currently my dual channel is 256mbramx2 = 533mhz...i fi wan to make it to 1066 i can eitheir add 256mbx2 again or just one piece of 512 533 makes no difference rite???

Is there much difference in performance between a ddr2-667 ram and ddr2-800?

And anyone of you are using Samsung ddr2-800 rams? I've never heard of them until now. How is their performance like? I took a quick glance of the chips at the shop and i couldn't locate the 'SAMGSUNG' word...just the model number...i wonder what chips they are using.

Those Samsung rams costs rm220 for a 512mb stick. They were recommended to me by the shopkeeper when i was about to select a pair of KVR ddr2-667 rams. I'll be using them on a C2D e6300.

never heard of them

Sorry got noob question,
Is it that important to achieve 1:1 ratio with processor ? What if I dual channel 667 /800 Mhz ram.

That would make effective FSB 1334/1600 . Is that no good or it has no beneficial effect ?

I think you're using the wrong terminology. RAM frequency ≠ FSB. FSB is for processor. And dual/single channel doesn't change RAM frequency either.
To sum things up (all can be found on the 1st page):

Effective FSB = base FSB x 4 for Intel system OR base FSB x 2 for AMD system

Effective RAM frequency = base RAM frequency x 2 for DDR & DDR2 RAM

1:1 ratio is acheived by matching base FSB with base RAM frequency (no "effective" stuff, no multiplication). This is highly recommended for optimum performance, and is especially important for AMD systems because the AMD FSB is not very efficient when it is slower than the RAM.

[waiting for someone to correct me ]

yu_wang..I am sorry but i don't understand...

it's ok...im not sure if i do either.
i guess everyone reads the detailed explanations on the 1st page and feels like posting, "too long didnt read"
Remember...Google and Wikipedia are your friends!

l0l ... i am a person who is lazy to read

mine is dual channel 256MB ddr2 667MHz, so what is my effective FSB?

If i put in one 1GB with 256MB, compare to 2x 512MB, which combination works better for my lappy?

assuming all is using ddr2 667MHz. mine is thinkpad R60.

If I am not mistaken your max FSB u can go for is only 1066 no matter how much u add???

Correct me if I am wrong

dude!dun u get it.dual channeling does not affect ur FSB speed.ram frequency is NOT FSB speed.2 533mhz rams will not increase ram speed 2 1066 or FSB speed 2 1066.2 rams equals 2 more memory.not more speed

btw,im not 2 good at this.wat i wanna ask is wat does da timings mean?
DDR400 2-3-3-7.
CL2.0 wats dat mean?
wats CAS?
wats all dat in layman's terms pls?i din really get charge n go's explanation at page 2 cos he din cover everytin.pls explain.thx a lot

yeah u r right..i was wrong...

Btw i also wanna know wat r timings

please help me with the above question! thank you!

my friend advise me to get a 2x 512mb ddr2 667Mhz rather than 1x 1gb ddr2 667Mhz for a new pc setup i am planning to buy (Core2Duo E6300).

appreciate it if someone can explain in layman terms just how much of a performance issue dual channel memory (or lack of) it really is? does it really matter that much? in which cases? 3D games? if there is a detailed test/review site to point me to that's be great!

my plan is just to get a 1GB stick and upgrade to 2GB when memory prices come down in the future.

thanks, guys!

2x512 better...dual channel
