As many of you know Intel has launched numerous stepings of Conroe over the past several months and the most recent is the B2 stepping. All of the reviews that have gone up today are all based on B1 steppings. While the performance difference between B1 and B2 steppings is less than 1 percent I don’t think it’s fair to go into an in-depth overclocking section as we do not have the stepping that will be available to the public.
Legit Reviews has three Intel Conroe processors; E6600, E6700 and the X6800. Our E6600 was an early sample and was based off the fourth stepping of the processor and was a B0 revision so it wasn’t used in the review. It wasn’t a great overclocker and was an early stepping so it wasn’t included in our performance testing. Since some are wondering what other processors can do we included it here for you to check out. We tried every voltage combination possible, even going up to 1.6V, and this is the best that we could do.
Here is the hightest overclock on out Intel Core 2 Duo processor E6600:
Next up is the Intel Core 2 Duo E6700 processor, which is a stepping 5 revision B1 processor. This is the processor that was sent to all the review sites. It was able to do much better than the previous stepping 4 processors!
The last processor we have to overclock for you would be our Intel Core 2 Extreme X6800 processor. With a 5th generation steping and the B1 revision this processor was the best that we have seen to date. It was able to overclock all the way to 3.9GHz with hardly any issues at all.
As you can tell we took three different Conroe cores and our overclocks ranged from 3.2GHz to 3.9GHz. This wide range of overclocks can be due to a number of things, but none of them matter because all of the shipping processors should be B2 revisions. If you are buying used processors on E-Bay or some random sites forums beware the older steppings as they are buggy and poor overclockers!
