Looking for table of hardware limit on ESXi 4.1

Hi,

I've been searching for some kind of table showing the difference between ESXi 4.1 editions.  But I always got the data for version 5 instead of 4!

I'm particularly interested in knowing the memory limit for each VM on ESXi 4.1 free and paid editions.  Alright, my vSphere client tells me that my free license gives me 256GB limit on the host hardware.  That's more than enough.  But how about the memory for every VM?  What limit?

If someone is able to find that table, I'd appreciate a lot.

TIA
