Recnelis, I arrived at the same exact conclusion that you did. The Corsair PC4000 Pro and the OCZ PC4000 Gold is nearly a toss up when looking at the reviews. I have OCZ PC3500 EL and I've been very pleased with. It'll do DDR440 at 2,3,2,5 timings. So, I know OCZ is excellent stuff. I decided to be adventuresome and ordered the Corsair Pro. It should arrive by tomorrow. I'll post my results.
If you are on a budget, then get cheap RAM with the BH-6 chips and overclcok the snot out of it. But, I can afford the extra expense. What I'm trying for is using the 1:1 ratio on my 2.8C and hitting at least DDR500. I don't see that happening with PC3200 sticks using BH-6 chips with any degree of certainty, especially with my IC7 that only allows 2.8v max vmem.
