Newegg reviews aren't that trustworthy, especially the RAM ones. RAM requires very specific settings to get it to work at 100%, and if you don't know what you're doing when overclocking and setting them, you'll get bad results. Of course, that's mainly because most people won't take the time to research the parts and the process. Newegg reviewers are generally not thought of for their technical skills and knowledge. For example, the very first review of the Geil sticks has a con about overclocking. 1333 mhz CL 9 sticks are not meant for overclocking as they're simply too slow. The reviewer has an unreasonable expectation of the part, which is common in Newegg reviews.
If you're really worried about it, here's some G.Skill sticks
for $5 more.
