I have a Dell PowerEdge R310, Intel Core i3-550, ST: , it is out of warranty, but I need to make a memory upgrade to 32gb ram or the maximum supported. So I need to know what kind and size of Memory do i need to do so?

I read about the Core i3-540 that says to use 4 rams of 4GBs (16GB) PC3-10600 1333 speed UDIMM, but i don't know if this info apply to the Core i have (intel Core i3-550)

Thanks!
