John:
I was trying to understand why AMD 760 tests at by Sharky and anandtech were no as consistant with other results we have heard about before.

anandtech.com
sharkyextreme.com

It seems that sharky uses 128 Mb of memory for his tests which makes a lot of disk swaping occur and anand uses 256 Mb which appears to the high limit of support for unregistered DDR memory at this time. Sharky clearly points out that the test AMD motherboard motherboard has 4 DIMM sockets. If one is using unregistered DDR chips, only 2 slots can be filled.

It seems like we will be seeing those registered DDR chips very soon to support memory capacities over 256 MB. I can believe that registered DDR will cost almost as much as RDRAM. LOL

Current price quotes for varoius types of memory from same manufacturer.
128 MB PC133 $ 109
128 MB PC1600 $ 166
128 MB PC2100 $ 182
128 MB PC800 $ 243
256 MB PC133 $ 256
256 MB PC800 $ 505
256 MB PC1600 $ 420 (registered)

It is clear that DDR is not going to be a low cost platform for performance computing unless they support higher densities of unregisted DDR DIMMs (largest DIMM I have seen is 128 MB) or registered DDR comes down in price.
