I want to buy an Intel CPU (with quad-core) and a motherboard that supports more than 32GB. I was looking for a motherboard that has a 1155 socket and 64GB maximum memory support. However, from what I found, the max memory I can find is 32GB.

Is this a technical limitation for 32GB of RAM, or have I just not been looking in the right places for a motherboard?

I reworded the question so it should no longer be a shopping request, hopefully it will be good enough to re-open the question. – Scott Chamberlain Mar 18 '13 at 19:29

I have looked at various motherboards - all seem to say a maximum of 32GB of memory, the chipsets (which state the same) and the processors...

All of the 1155 pin processors I can find only seem to support a maximum of 32Gb of memory at the CPU level, so, I don't think this is possible.

Even entry level servers (Xeon 3xxx) that are based on the 1155 CPU package state a maximum of 32Gb of memory.

It isn't until you get to the Xeon 5xxx series that you see bigger memory allowances, so, I believe this limitation is on the actual 1155 package processor itself.

For the curious, this is because Intel now integrates the memory management unit for their CPUs directly into the CPU die now - and thus, the maximum memory limits come from a combination of available motherboard hardware, and the actual CPU model itself. – Breakthrough Mar 18 '13 at 17:40

Unfortunately LGA1155 only supports 32GB
