DDR2 1024x2 vs 512x4?

[Infrnl]

With DDR2 will you notice a performance loss between running 512x4 and 1024x2? I know as on earlier AMD systems running DDR ram there is a significant difference since the system will switch between 1T and 2T when you fill the second set of ram slots, but I wasnt sure about DDR2 since you already start with the 2T command rate.

If anyone can clue me in on this, it would be greatly appreciated.

Thanks

No replies, are you serious, lol did I answer my own question already. I know someone has to know.

The main reason why I am asking this is because I ordered some corsair PC2 5400 XMS 512x2 for $83 and if I buy 2 of these kits It will cost the same as the 2GB kits without having to wait for the rebate; which may or may not go through.

Get 2x 1Gb so that if you ever want to add more in the future, or if you want to take that memory to another motherboard in the future and then add more, you have the space to do so. 4x 512Mb means you'll need to throw it all out and buy 1Gb sticks if you wanted more than 2Gb.

Newer fill all you slots on a build, always leave room for expansion, you never know what will come about in a year or two

Tests show that more memory sticks will generally give higher benchmarks, and this also sometimes depends upon them being single or double-sided sticks. So you have to weigh the two: would you want to add more later, or do you want what is fastest.

I agree with you guys in a sense; however by the time we upgrade DDR3 will probably be out and who needs more than 2gb of ram? although there is a good deal on corsair 2gb kits right now, so I may jump on that deal. the only downside is I thin I can get higher overclocks by using 512 sticks. maybe I will wait till nex week when my other 1gb kit comes for a different system, then I can test it to see ow 512x4 will work. the plus side of 512x4 is that if I do want to upgrade my current main system I can take the 512x4 and put it in another system and get a 2gb kit or 2 2gb kits for my main system. of course after I get more ram, prices will probably drop even more,lol never fails

What is the type of u'r rig....Is it AMD or Intel based ?

Actually, generally the fewer sticks you use the higher the o'clock. When I said: "Tests show that more memory sticks will generally give higher benchmarks, and this also sometimes depends upon them being single or double-sided sticks. So you have to weigh the two: would you want to add more later, or do you want what is fastest", I was referring to the SAME SPEED. Same FSB. More sticks will usually yield higher bandwidth results.

But when you're dealing with the highest o'clock, you have to remember that with multiple sticks the highest FSB you can get will only be that of the slowest "weakest" stick. Furthermore, something else to ponder is generally the larger the stick, the lower o'clock you can get out it. It's much easier to find a 256mb PC3200 module that will do PC4000, than it is to find a 1gb PC3200 module that can reach PC4000 speeds.
