Well, I finally got the time to plug in the 3rd CPU I got from the old box of goodies I got some time ago. It isn't based on Penryn, as seen on the CPU-Z screenshot and validation link. It's a good overclocking CPU, and performs really well. The 4MB L2 cache has done wonders with the CPU, and performance has really improved. If you would like to see the initial benchmarks and the 50% OC, then expand for more...
Disclaimer: This is an ES CPU, retail may or may not have changes from this sample.
This is just a quick and dirty FSB overclocking and nothing fancy. This overclock can be done even by those noob overclockers, the processor is just so OC friendly. I reached 1600MHz FSB (400MHz QPB) in just under 10mins, and it's rock stable. I can run multi-threaded prime for more than 2hours, complete all kinds of FutureMark* benchmarks, and it'll run happy with Aquamark03, and even Doom3 time demo. And yes, it's on stock cooler and all stock voltage too.
For the curious, test set up can be seen on the CPU-Z validation, and aside from that, I am using a typical WinHEC 550 Power Supply, and stock cooler. Here are some early stock benchies for you to feast on going head on against Intel® Pentium® D 940.
That is all for now, FanBoy out...
