The Patriot Viper Series memory kit comes in a nice looking black box. There is an excellent photo of the memory modules on the front along with a label telling the specs in large font. The latter is significant for those of us whose eyes aren't that great anymore, most have specs so small I need my reading glasses to make them out.
Inside the modules are in a blister pack that thankfully isn't hermetically sealed.
The Patriot Viper's heatspreaders are a nice blue color with split fins. The Patriot logo is chrome with a mirror finish. Patriot uses a black PCB which looks good with the blue heatspreaders. The modules are fairly tall, about ¾” taller than the standard memory module, but shorter than some other finned modules, for example the Corsair Dominator.
The modules are tested to run at DDR3-1600 8-8-8-24, at Intel's required Vdimm of 1.65v. The onboard memory controller of the i7/i5 will suffer damage if the memory is volted above 1.65v.
The Viper Series heatspreaders are very interesting. They are made of an extremely light aluminum alloy. The entire heatspreader is a set of fins, with only enough “flat part” to cover the memory chips. Each fin has an extruded rib that runs the height of the heatspreader. Rather than using inefficient thermal tape or thermal pad, the heatspreaders are epoxied directly to the chips, giving the best heat transfer environment you're going to find. No, you can't remove the heatspreaders, but why would you want to?
The business side of the Viper heatspreaders are copper plated, giving them the increased thermal conductivity of copper. I don't know that I have ever seen copper on a memory module heatspreader.
