He tested it on a i965-based motherboard and as per his post, the performance is great. He even overclocked the baby and hits 4GHz. Now that's really amazing, four (4) cores on 4GHz. Maybe I should begin posting my server pets as well. Expand for more and check out FCG's toys.
If you haven't heard by now, Intel will be releasing a Socket T (LGA775) quad-core Xeon during Q1 2007. This chip will be identical to the Kentsfield, save the name string, and the dual processor (DP) ready Clovertown except for one small difference. Binning. Expect the Xeon flavored "Kentsfields" to run cooler and with less voltage than their desktop system brotheren.
Here's the expected lineup:
X3210 - 2.13GHz, 2x4MB L2, 1066MHz FSB
X3220 - 2.40GHz, 2x4MB L2, 1066Mhz FSB
X3230 - 2.66GHz, 2x4MB L2, 1066MHz FSB
X3240 - 3.00GHz, 2x4MB L2, 1333MHz FSB
Price should be very similar to Kentsfield, where the X3220 is the equivalent of the Q6600 and the X3230 matches the QX6700. As you can see, these CPUs are the newer B3 stepping. Expect this to be the retail revision when these particular CPUs appear for sale in early 2007.
Here's what CPU-Z shows for the X3220 running on my watercooled Asus P5B. Although this screen shot shows a modest 400FSB I've had no problems with 450x8 with this combination. I prefer to run the lower FSB though as I can use a 4:5 memory divider to reach DDR-1000 quite easily.
