Test these very thoroughly for a couple of days, using both Gold Memory and either MemTest86 or MemTest86+, because it's made of RAM chips that are overclocked by 36%: APHnetworks review

Notice the chips in the reviewed sample are Hynix H5TQ2G83BFR-H9C, and H9 means a speed rating of PC10666. See page 4 of this Hynix document.

The same PC10666 chips are used in at least some Ripjaws X PC17000 modules, only G.Skill requires those modules to show zero errors during factory testing. Yes, that means slower modules are allowed to have more than zero errors and still be sold, and G.Skill doesnt do super-strict testing with the $1M+ machines that better companies use but only with PCs.

Are they backward compatible? Thanks.

Farmer said:   Are they backward compatible? Thanks.Yes. All DDR3 and probably all DDR2 memory modules are, because their SPD chips provide the computer the parameters for several memory bus speeds that are slower than the one most prominently featured on the package. Also it would be strange for a company to sell DDR3 modules made with 1333 MHz (PC10666) chips, which are about the slowest ones still in production, to not work as PC10666.

It's safer to buy modules made only with chips clearly marked with the branding or part numbers of the actual chip makers -- Samsung, Micron, Hynix, Nanya, ProMOS, PowerChip, Elpida, not Kingston, Corsair, G.Skill, Patriot, Mushkin, etc., and that are not overclocked. Generally that means modules with no heatsinks and with standard voltage ratings (no more than 1.5V for DDR3, 1.8V for DDR2), and if you can't inspect the very samples before purchase, there's no way to be assured of that, except by buying Samsung or no-heatsink Crucial modules.
