I have the requirement of about 32 GB RAM.
I i use
intel Core i7-860 Processor (8M Cache, 2.80 GHz)
WIll that be OK with
intel S5520SC Server Motherboard
The motherboard is only compatible with Xeon 55xx series CPUs and not the Core i7.
It states that it has 12 sockets, however I am unable to find further details. I used 4GB sticks in the previous version of this board without problems, however I cannot find any specification pages that back this up.
...Edit - Found this link, it shows compatibility for up to 8GB modules, this is not for your motherboard, but it is for one with the same chipset - which is usually the limiting factor in things like this.
The Intel S5520SC Motherboard can up to hold 96 GB RAM
Each memory slot can hold DDR3 PC3-10600 or DDR3 PC3-8500 with a maximum of 8GB per slot.
if you want to use that Core i7-860 you're limited to 24 GB RAM. If you want more get a Xeon mainbard like the one you posted.
