Which RAM ?

[vo]

I have a 3000 Dimension that accepted and currently using PC3200 (DDR400) non-ECC.

However, when I use Everest to check my system, here are the number it came up with:

Front Side Bus:
Real Clock: 133 MHz (QDR)
Effective Clock: 533 MHz
BandWidth: 5667 Mb/s

Memory Bus:
Real Clock: 167 MHz (DDR)
Effective Clock: 333 MHz
BandWidth: 2667 Mb/s

To me, that's mean my system can use PC2700 but not PC2100. But I remembered someone said that it can use PC2100 due to the FSB ????
Is it me or the number seems to be off

That means that your memory is running at 167 but your processor is running at 133... Your running Async, but the good Async.

you can use all three but PC2100 would slow your PC down, and PC3200 can be had cheaper I think so just use PC3200 if you can then PC2700 if you can find it abit cheaper but don't use PC2100 it will slow your system down.

I think.....

those numbers look pretty right (& good) to me.

But I dont understand why my memory is running at 167/333 ...
My RAM is PC3200/DDR400

Okay.

Technically, your FSB is 133 MHz (quad pumped to make 533).
Your RAM is running at a higher divider, 166. (normally, you'd be running at 133 (PC2100, but on your PC, it's got a funky divider setup)

Now since you have a Dell, you are likely stuck there, since i doubt you'll have any bios options to raise the divider.

I really doubt running the RAM at 200 would make much of a performance improvement, if at all, anyway though, since your FSB is so much lower.

QFT. Basically, your current ram is being underclocked to PC2700. No, there is nothing you can do about it.

Thanks Tick !
Grrr ... this is my first Dell and I want to upgrade to 1G but was wonder how much better between 1G DDR333 vs 512 DDR400.
I never attempted to have DC set up ... actually, I never acquired the same set of RAM.
