registered ECC & Xeon 34xx in non server 1156 board?

[freifacht]

Hello everybody,
just stumbled over this forum.
Maybe i can get some advice or help

I am assigned to build a nice and reasonable priced little workstation.
I chose a Socket 1156 board, most likely the ASUS P7P55D.
One requirement the system has to fulfill is that it should have 8 GB RAM with the option of updating to 16GB.
So plugging in two 4GB modules seems to make sense because this would leave two RAM sockets free for another two 4GB modules.

Now officially the "consumer" 1156 boards support "regular" i5 and i7 CPUs and non registered memory.
But most of you already know (i guess) that the X34xx server CPUs can be used as well.
Now the advantage of the those CPUs is that the memory controller is integrated in them.
Also they suppport registered ECC memory.

My question is: can registered ECC memory be used in a "Xeon 34xx + P55 board combo"

unregistered regular memory costs apprx. 160 EUR per 4 GB module.
registered ECC memory costs apprx. 110 EUR per 4 GB module.
So if this worked i could save my "client" about 200 EUROs.

Is there anyone out there who could provide some information?

many thanks in advance

both the core i5 and i7 have the memory controller built in but i dont think P55 motherboards support registered ECC

thanks for the quick answer.

It was this article http://ixbtlabs.com/articles3/cpu/intel ... 50-p1.html where the author talks about using registered ECC memory with Xeon 34xx CPUs. But he is not very precise about the mainboards although to me it seem that he is talking indeed about P55 boards.

Anyway, that article lead me to the idea of eventually combining X34xx CPUs + registered memory in a P55 board.
Still waiting for its author to answer my question.
