help in setting dual channel ram config ...

hi friends

i have bought 1 gb ddr 400mhz hynix chip ram & i have 512 mb ram of same speed before.

now i want to know how to setup the dual channel memory?

i have another 1 gb ddr2 ram of 667mhz,
can i setup a dual channel setup memory.

my mobo is intel original 915 gv. i am using win xp.

please reply me friends.

No you can't setup ual channel with the rams currently you have.

You need another 1 GB ddr 400 Mhz Ram or 1 GB ddr2 667 MHz Ram ( Recommended - assuming yur mobo has 2 ddr & 2 ddr2 slots )

don't know about running ddr & ddr2 concurrently on same mobo.

for dual channel ram u must have same speed and same memory

dual channel is activated when putting in slot 1 and 3 OR slot 2 and 4 OR all the four. dont know with 8 slots mobo

ok can i run all of them on my system? so that i have 2.5 gb of ram.

YES if all the speed is same but not on dual channel

even if you run all of them in your system the lowest speed will only be the effective speed.. in this case 400Mhz

dual channel mode increases the bit size ie from 64 bit to 128 bit..

guys i also have the same question.i also have a 512mb ddr ram.
now if i get another 1gb ddr ram of same frequency.then how should i put them.
1. i mean can how can i make the memory 1.5GB.in which slot should i put the 1gb ram.i have four slots.

2.also is dual channel setting better.should i get another 512mb ram or 1gb.
which one will be better.

please do reply.

guys please reply.

pal, you should go through your MOBOs manual and you will find out
whether you have DDR2 slots or DDR slots than only you can proceed
putting in the DIMM.
For dual channel i would recommend same size, same frequency and same make(this "make" is debatable ) memory module having said that
today i myself
installed two different frequency DDR2 DIMM of 533 and 667 MHz but of same size i.e 1GB on my GA-945GZM-S2 motherboard both are working in DUAL CHANNEL!!.
Also if you want your system memory to be 1.5GB, yes you can add an
1GB and 512Mb given that slots are of same type and frequency.

only DDR2 can run in dual channel, not DDR

well i think it can also run.

It depends on onboard memory controller not on DDR2 or DDR

^ Right said mate.
For example intel 856GBF which supports ddr rams only can run in dual channel mode.

Certainly you should get 1 GB module. It's the better choice.
