Default (2 x 1gb) vs (4 x 512mb)

I'm having an issue....

I'm only going to be able to get my system with 1 gig of memory.. and it will be a 2x512mb dual channel kit... the motherboard I am getting supports 4 gigs across all 4 dimm slots... but is it ok to use all 4 up like that?.. is it gonna stress it out?...

it's cheaper and more convienient for me to go 4 x 512 as opposed to 2 x 1gb.. not to mention that 4 x 512 would all have a cas of 2.5... the 2 x 1gb would be 3...

i would say stick with the minimum amount possible of sticks.. so you always have room for expansion. However, i dont believe theres any evidence showing that it may / will stress a system out.

Well, for the record, I don't think going past 2 gigs is really practical.. by the time that would be even necessary, it would probably be time to move on to DDR2 anyway.

I totally agree with your MikeReiner. Once you get beyond 2 gb as a necessity, then I'd move on to DDR2 and higher speed memory. Go with the 4x512mb.

I've heard that if you use all four slots on most motherboards it downclocks the memory to 333 MHz.

I'd say go with the 2 X 1GB if you're looking for that much memory. Like the others said keep the slots open for upgrading. And I assume you are running an intel board because you do know that AMD sockets don't support DDR2 just yet, right?

It's an AMD system, and I know they do not support DDR2. BUT when I make the move to DDR2, I will be on a whole new system, and AMD will then support DDR2.

And like I said, I will NOT be upgrading past 2 gigs of mem on this system, no point.

But man.. are you serious? 4x512 results in DDR333?......ehhh...

2x1gb is so expensive compared to 4x512...

That's what I've heard. Honestly, just go with the 2 gigabyte sticks, it's a little cheaper anyway.

Go with the 4x512. The frequency may seem slower, but to compensate for this, you have every slot talkign to each other and transfering crap at a much higher rate. Frequency isn't everything, moving things however is. If you have the same amount of storage, which in your case is 1 gigabyte, and you can only move it across 2 sticks, you'll be slower as oppossed to moving it across four sticks.

Trust me, go with the 4x512, you'll definetly like it.

ahh but thats where you are wrong.
it costs $67 for a 2x512 dual channel kit on newegg with a cas of 2.5,
http://www.newegg.com/Product/Produc...82E16820145440

the cheapest 2x1gb that has a cas of 2.5 is $146... so it's a little bit less cost effective..
http://www.newegg.com/Product/Produc...82E16820231047

my problem is, I wont have the cash needed to get the 2x1gb.. but I would for the 2x512.. (for temp use, planned on upping it to 4x512, but now that I see it would go ddr333... I don't really want to...)

Oh, I see what you're saying. My bad. And sorry for the wrong information, I thought that it was cheaper. Oh well, go with whatever feels right . I don't really know.

Hmmm... that sounds real good... do you know of any site that talks about this?

When you use 4 sticks with AMD processors the memory has to run at a 2T command rate. While if you have 2 x 1gb it will run at 1T command rate. 1T is supposed to be faster then 2T. So the only time I would suggest getting 4 x 512mb is if you are going to be getting really good overclocking memory. If you arent overclocking then just stick with the 2 x 1gb. By the looks of how much you are spending I think that you should just get the 2 x 1gb.

No no no! Dont go with the 4x512. Do you have any idea how hard that is going to be on the memory controller. I was told to ALWAYS get 1gb sticks when gettin into those amounts. Only 512 when your halfing it.

Good point. I agree with The Amish Kid and ArrizX, they're both right.

Could you give me a link or somthing to back this up? To me it sounds like you are just making crap up.

Arhg... if I get the 2x1gb then I have to get a weaker video card..... right now i'm thinking the 7600GT.. but if I go 2x1gb over 2x512, then i'll have to get a 6600GT...

Even if you dont beleive me by it being hard on the memory controller (thanks to Alvino I learned), get the 2x1gb because, there is room to upgrade!
