Well, I did a bit of research & pulled info from quite a few sites and it looks like GeIL is (now?) basically the same company as OCSystems, which claim to only be a reseller, but have a very bad rating - both on resellerratings.com & anandtech.com.
The GeIL ram did perform good in a lot of reviews, but some of those test rigs and ram were hand picked by GeIL and it looks like it is basically overclocked to begin with, especially when it needs about 3v to get to it's rated speed.
I'm sure you could get the same or perhaps better from some good Corsair XMS PC3200 C2. I've been eyeing a stick on Newegg's page for a while now

Anyone know of a US vendor for Triplex Ti4200's other than OCSystems?
