Hi All,
according to Sandra, the reference chipset (875P 2*PC3200) should be
around 5000 MB/s.

I'm using Crucial 2 * 512meg - PC3200 ECC

Doesn't this seem a little low ?

TIA

Bill

Are you sure you have your RAM in slots 1 and 3 and not 1/2?

It is low:

Same board, same speed (not ECC ram tho)4810 MB/s

I dont believe your in dual channel, thats the only reason I can see for
you getting such a low score.

Hi Philip,
you were right, I did have the memory in slots 1 & 3.

I moved the memory and now get 4340 MB/s

Thanks

Bill

You mean you had them in the first 2 slots(one blue one black) now you
have them in A1 and B1 (blue) right? Thats the proper config for dual
channel.

Well, with that bandwidth, it is obviously dual channel, so you dont
need to open you box again to check :)

Glad it helped.
