Single Core + New Memory Dividers
Next, we move on to the single core Athlon 64 FX-57 running at 2.8GHz. The FX-57’s high clock speed should increase its dependency on a faster memory bus, but by how much?
The DFI board only offers support for 215MHz DDR430 and 233MHz DDR466 at 2.8GHz; given the lackluster improvement that we’ve seen from ~DDR433, we decided to only focus on DDR466 performance.

Despite the high clock speed, the FX-57 doesn’t benefit any more from DDR466 than the dual core chips had seen with DDR480/488.

i remember when ddr400 wasn't official...Joepublic2 - Monday, July 11, 2005 - link
"Potentially as a backup plan, the Rev E chips include unofficial support for memory faster than DDR400, without overclocking the Hyper Transport bus"This is an appeal to overclockers, nothing more.
"why isn't jedec officially supporting ddr500?"
JEDEC will not approve any more speed grades of DDR without Samsung and Intel's blessing.

Good article. This will probably help me sleep better at night when Socket M2 comes out and I still have an X2 939 :preactor - Monday, July 11, 2005 - link
hmm kinda sad that it doesnt improve performance much, but then we already know low latecy is better for amd cpus.are we going to see a review on the ocz gx ram?

keeps getting better and better.
