In this test report with the upcoming 955 chipset (using the Intel reference board) they easily made it to DDR2 1000 MHz in dual channel - 100% stable as they say. It seems the new 955 memory controller has plenty of headroom. http://www.legitreviews.com/article.php?aid=187&pid=2 The memory at very high latency of 5-4-4, but the 1000 MHz frequnecy is more than compensating for this. They could run the board at 250 x 15 = 3.75GHz Dual Core. Well if this holds true for the retail stuff - we don't have to worry.
