Intel Sandy Bridge-E Boards Have Problems with Large CPU Coolers

Quad-channel memory introduced by new support high performance processor Intel Sandy Bridge-E apparently caused a bit of a problem for motherboard makers wondering how to include support for large CPU coolers without giving up the features.

When Sandy Bridge-E Intel set out to develop the architecture, one of the most important improvement is to bring this chip is support for higher memory bandwidth.

To achieve this, the chip manufacturers settled with the increasing number of channels can support the processor memory and decided to use the quad-channel configuration.

In this theory should be able to provide 33% more bandwidth than the tri-channel memory controller used in the core Nehalem, but adding a fourth channel memory is not as easy as most of us think.

The most important constraint faced by Intel the road is the need to optimize the trace on the motherboard to maintain constant latency between the four DIMMs installed.

Do this for all installed DIMM sockets placed at approximately the same distance from the CPU socket, which causes a drastic design of the motherboard components placed.

I'm sure by now you all saw a X79 board and knew all about the layout used, but what most do not know that placement is that it seems to cause all kinds of problem with large CPU coolers.

Month is designed for use in motherboards with memory installed on only one side of the CPU socket, so it will fit on a cooling board LGA 2011 a long shot, the report SweClockers.

Moreover, the problem is not limited to only one manufacturer of motherboards, but it seems to affect almost all boards are designed LGA 2011 until now.

How big the problem really is still uncertain at this moment in time, because most of the information about LGA 2011 Sandy Bridge-E and platforms are still in NDA, but the user is sure to take lots of care When choosing their parts in such systems.

We will continue to up to date on how things evolve from this point, even the early adopters are advised to go to cooling water as this causes the least amount of guaranteed.
