I'm complaining about crucial because their products don't work reliably at any voltage.

The parts should work reliably at 2.0v, but the problem is that they're not actually 2.0v parts. Running at that voltage you're overclocking the parts.

But again, there was nothing indicating the voltage of the memory on the site of the store I bought it from nor on the packaging - only on a sticker on the modules themselves. Newegg at the moment do not specify any details about voltage on the page for the RAM I have BTW. But again, that's all irrelevant. It's up to Crucial to sell a product that's not complete garbage. And I've been through 4 modules that indicate they can't do this.
