NForce2 Dual DDR question

Forgive the ignorance of this post but since the new NForce2 uses this new Dual DDR switching thingy (told ya my knowledge was basic) would it not be advantagous finally to have more than 512meg of RAM? Seems that if it switches info between slots it might actually use the RAM above 512M.

Thanks in advance for an answers.
 
512 was more a limit of windows 9x, me then the MB.

if you are running win2k, XP the ram will be put to better use.
 
So this is the 1st I have heard it might help. I play BF1942 and it seems to eat up GOOBS of RAM. I just might have to add another 512MB stick of Corsair to the NForce2 and see if this quickens the puppy.
 
Dual channel DDR kind of works like Stripping two hard drives... it will R/W data to both memory moduals equally. That's how you get double the performance (so to speak).

In other words, if the system needs to write 10 MB of data to memory, it will write 5MB to each of the modules at the same time...

If that makes sense.
 
Chuckle, ok... Let me ask it another way. Being that its basically a gaming rig, with BF1942 doing the most resource hogging. Will 1 gig of RAM make any *real world* difference vs 512 mg with a NForce 2 board? Thats the basic premise of the question.

Click to expand...

Only if you use more than 512MB of RAM during play will 1GB of RAM make any difference.

But, 1 stick of 512MB RAM will be slower than 2 sticks of 256MB RAM on a nForce2 motherboard, due to dual banking 128bit memory access (TwinBank).
 
If you have 512MB RAM right now, I wouldn't worry about it. You're not going to see any difference (just by upgrading the amount of memory). There are very few applications (games...etc.) that would benifit having more than 512MB Ram.

I actually downgrade my system from 768 to 512 (The wifes computer had mem go bad so I gave a stick up) and I haven't seen any difference in performance in anything. I run XP Pro.

Now... If you have a Single 512MB stick in it now, you may see increase in performance if you buy another "identical" stick and make your system dual channel... but it's going to be the bandwidth increase that gives you the boost, not the amount of memory.

However, if you are currently running dual channel (2 - 256MB sticks) now, I wouldn't fool with it.

Hope that helped.
 
If you see the review here, you will see that actually 2 sticks does not make all that big a difference on this board anyway.
