This week, as I promised, we are talking about the new revision of the 2011 socket. To be exact the third one. We will be talking about backwards compatibility and what this particular revision brings new to the table.
Firstly I want to say that unfortunately this revision denies any backwards compatibility idea. Yes, it has the same number of pins and it is the same physical size, but electrically speaking it`s a little bit different.
Being electrically different means that the pins have different roles from the ones in the first and second revision of the socket. For example the PCI-Express controller pins were moved in comparison to the old location. Now this is just a hypothetical example, as we don`t know exactly what pins moved and what roles have been interchanged.
Next, I want to talk about why Intel made this decision. This switcheroo was needed because we are moving from DDR 3 to DDR 4, which translates in a whole new memory controller so it wouldn’t have been compatible anyway. That physically needs a change of pins, so that third and fourth gen HEDT CPUs won`t fit and therefor, Intel evicted the thousands of CPUs that were fried because some of the “know-all” users would’ve tried to fit those CPUs in X79 Motherboards.
I hope I made clear for you why this revision of the 2011 socket isn`t backwards compatible. Until next time I ask you a little question:
Do you think that no backwards compatibility thing is bad?
