A8N-SLI Deluxe, CPU and 2GB RAM

[Emultra]

I have the board above, and 1GB RAM.

I could easily buy another GB, and I want to in fact.

The problem is that my A64 3200+ Winchester will do something with the DDR speed or something if I have more than 1024MB RAM.

My questions:

1. How many Mhz can the A8N-SLI Deluxe support in case of a CPU upgrade, and will it support the upcoming Dual Core Athlon64's?

2. Will another pair of Corsair ValueSelect 1024MB RAM (2x512) fit well with my current pair, to make 4x512MB RAM, and will it still be Dual Channel?

The A8N-SLI will support the current X2, up to the 4800+ as long as you flash to the newest BIOS first.

Yes, you can definitely have 4 X 512MB of identical RAMs work in dual channel, but it'll only works with 2T command rate (limitation of the Winchester mem controller), and manually adjust the mem frequency to operate @ 400DDR.

So if I upgrade the CPU, I should be fine with another pair of identical RAM that I have now?

What is the market like for selling used CPU's? Mine hasn't ever been overclocked.

Yeah, it'll be fine. And I suppose you can try selling your CPU in the "For Sale/Trade" section -- not sure how much it'll fetch though.

You will not have any problem selling that on ebay.

Also, I have the 3500+ Winchester and just went through what you're talking about.

I added two more sticks of 512 to my system so I could get 2GBs of RAM for BF2.

My system automatically set the RAM to run at DDR 333. I had to manually set it back to 400MHz. However, I could no longer use the 1T command rate as mentioned above.

I did some testing and 1T to 2T was a big hit in the memory bandwidth department so I decided running the four sticks wasn't worth it so I picked up two 1GB sticks and can now run at 400MHz with a 1T command rate.

I'm now going to have to return the two new sticks of 512 and sell my two old sticks on ebay. I don't think I'll have any problem selling them for a good price.

Later,

does anyone know if you can run DDR400 or higher with 4 512MB DIMMS with the new X2 Athlons @ a 1T command Rate?

Also will overclocking be worse with 4 sticks of RAM instead of 2?

DDR400 already works with Venice, San Diego and such, doesn't it? Don't know if you'll get 1T though.

You can run DDR400 with 4 Dimms, but you can't run 1T, it will always be 2T

2 sticks is always prefered for ram overclocks, but on A64's high ram speeds don't provide much of a real world performance increase, just in synthetic benchmarks

If it doesn't cost more than getting a new CPU, you may be better off if you get 2 X 1GB RAMs -- at least that way you get the 1T timing.

New guy here. I'm sorry, but I'm just trying to understand this better. So what I'm getting is that if I was to get two 1GB sticks I can OC just as well as two 512MB sticks? I always thought that if you wanted to OC you should stick with 1GB with 2 512 sticks? Any help on this is appreciated
