They already have an E6300 that they have been testing with. Not this week but the 2 weeks ago Price/Performance mentioned that they are testing with the E6300 and E4300 and plan to add it to the chart. I have already send Email to the editor. That was back in December. They informed me that they would be adding the E6300 soon to the charts. I thought soon was going to be in 2 or 3 weeks. It has been much longer than that.
Maybe they are waiting for a new stepping of the Conroe to be released. From the looks of things that would be something beyond the E0 internal stepping. For all we know Intel could be up to G or H stepping.
I agree. It's not like they have to buy an E6300, they can just set an E6400 multi to 7. That will give close enough results to present a PI for it.
The problem with setting an E6400's multi down to 7 is that when tested in a 965 chipset, it'll increase the NB fsb 1.167:1. There's a quirk in that it advances the NB fsb speed if you're not at the default multiplier. More info on this is in the link in my SIG.
It's a good thought to slow down an E6400, but it has it's caveats.
