PCShopTalk posted a review on the OCZ Blade DDR2 1066MHz (PC2 8500) 2x2GB RAM Kit

The modules themselves are shiny black with a silver OCZ logo that really pops out. The PCB is black, and the motherboard connector is a nice contrasting gold. OCZ put a new cooler on the Blade series of memory modules. It is made out of two pieces of pure aluminum, once on each side. The two pieces are then screwed together. This should provide superior cooling to the type of cooler that uses a plastic clip to hold the cooling pieces together.
