A question about DDR2 RAM....

Check your motherboard info to make sure that it will support 667 RAM, and you will probably have to change the BIOS settings to run in dual channel mode.

Slug: Thanks and yes, my motherboard supports up to 667 DDR2 and it has up to 4 memory slots. Are dual-channel RAM modules conveniently labeled as such?

Dual DDR is not a feature based on RAM module, it's a motherboard-supported feature.

That means if you have one DDR module installed on a Dual-DDR-supporting motherboard, you may start using the technology as soon as you install another RAM module (one which is almost identical with what you have, say, you must have two Twinmos 512 MB DDR RAM 400 MHzs in the end).

But, aware of this dual DDR tech, RAM manufacturers offer Dual Pack RAM modules, two identical modules in one package to make use of Dual DDR error-free.

I See

.

Thanks LEN! 'Tis the second time I got help from you

. Fortunately for me, the Intel 945P chipset in my board supports dual channel memory.

So for the last time (really sorry if I'm starting to get irritating

), I'll just have to get an exact same memory module as the one I already have (Or buy two completely new 1GB DDR2 667s).... plug it/them in the slot/s, then tweak the BIOS for the rest of the magic, right?

Again thanks everyone!

Only in Intel based systems. AMD has memory controller in CPU.

Plug memory in 'the same color' slot [see instruction book].

Alright! Thanks Duke of Serbia.

I forgot: buy another Apacer 1GB DDR2 533 model. Yes, you can buy faster memory but it's useless as the memory speed will work ALWAYS as the speed of the slowest model (the same story with hard disks in RAID).

If you want faster memory, you need to buy the new pair, and sold that Apacer.
