PCVS you are incorrect on your price assumptions.
Right now the sweet spot on price
is 16GB ECC/Registered DIMMs. Going to 32GB DIMMs is cost prohibitive, but 16GB ECC/Reg DIMMs are cheaper than 8GB ECC/Reg DIMMs per GB.
Not to mention, you cannot find reputable brands that actually
offer 16GB unbuffered non-ECC DIMMs right now, much less 32GB models. If you know of any, please post a link.
