Overclockers Club
"OCZ has produced a set of DDR3 modules that just flat out perform. At 1333MHz, the test results showed that the tight timings of 6-5-5-20 did help performance by allowing the modules to finish either first or second in all of the tests run. Where the OCZ Reaper X HPC modules really shine is when the clock speeds are ramped up. I was able to push these modules to DDR3 1900 with only 1.96 volts. Having the ability to overclock in excess of 274MHz over the DDR3 667 FSB spec on these modules is an incredible feat in my eyes. That is the most head room I have ever seen on a set of memory. So much so that it out ran the 475 FSB limit of my Intel Q6600.If you want to shoot for some records, I feel that the OCZ ReaperX HPC DDR3 1333 set of modules can get you there. As long as the rest of your hardware is up to the task."

Hispazone (Spain): The Perfect Computer 2007
"The new Perfect Computer continues the set tradition of obtaining an outstanding result that few PCs can reach. This all supported by actually unparalleled memory modules in the world of DDR3, the OCZ PC3-10666 ReaperX HPC Enhanced Bandwidth, not only because its speeds at more than interesting latencies but also because its disipation with no equal that puts OCZ in the elite of the DDR3 modules. These are the products used that we have considered a special mention because of its contribution to the performance of the perfect computer."

Big Bruin
"Many DDR3 modules suffer from fairly loose timings. The OCZ Technology PC3-10666 ReaperX HPC 2GB DDR3 Kit looks to address this issue as well as taking a unique, and aggressive, approach to module cooling. OCZ Technology has been one of the best manufacturers of enthusiast grade memory for several years, and they have put together another great kit. The OCZ Technology 2GB PC3-10666 ReaperX HPC DDR3 Dual Channel Memory Kit is a stride in the right direction with tight timings that are starting to rival DDR2. Given the features, performance, and price, the 2GB PC3-10666 ReaperX HPC DDR3 Dual Channel Memory Kit earns the awards of Highly Recommended and Great Idea."

Todo Reviews (Spain)
"This kit that we analyzed today can become an excellent claim for all those undecideds that have not yet decided to take the leap to DDR3. Ultimately, this kit by price and performance is one of the best that you can purchase at this time. Moreover, this is a product highly recommended for good price, excellent latencies at 1333MHz, good performance, Lifetime Warranty, and good overclock capacity to relaxed latencies. We grant Quality-Price Ratio."

APH Networks
"The OCZ ReaperX HPC PC3-10666 Enhanced Bandwidth 2x1GB memory kit is absolutely nothing short of impressive. From its consistent expected performance across the board, excellent heatsinks (Whether it's for real heat dissipation or of looks, it achieves its goal both categories very well), overclocking potential that totally blows you away, this RAM kit is backed by OCZ's excellent service and warranty as well. The ReaperX HPC PC3-10666 is simply a winning DDR3 package for its price and features, bar none."

"At first glance this memory is very impressive and it's doesn't just stop at great looks. At PC3-10666 speeds the memory can generate a fair amount of heat. Thankfully the heatpipe/heatsink combo used works extremely well and it allows the modules to remain cool. Of course excellent case ventilation is required for it to work to its full potential. The OCZ PC3-10666 ReaperX 4GB Memory is great at overclocking which is something any enthusiast will appreciate. It's also very stable, reliable and compatible. So you can rest assured that it will satisfy. If you are in the market for the coolest looking, performance laden DDR3 memory on the market, check this stuff out."

The Inquirer
"The X38 and later chipsets from Intel changed the equation to focus more on using the spare bandwidth and depend a little less on latency, but even there the in-sync approach, up to now, gives the best results. And, if you're keeping the FSB low, say at 1333, then a dual-channel low-latency DDR3-1333 may be the choice for you. ReaperX not only is the first in this series to support very low latency (CL 6-5-5 by default), but also incorporates a huge heat pipe assembly with aluminium fins standing on top of each module. The low module latency would match well with the low CPU mem con latency."

Think Computers
"The OCZ ReaperX DDR3-1333 2 gig kit met and exceeded all of my expectations. Besides looking good and keeping cool, I found the kit to actually perform better than my DDR2 kit. This memory will work in virtually every DDR3 motherboard, operating at the standard DDR3 Vdimm of 1.5v, andat DDR3-1066 and up. Crank the Vdimm up to 1.8v, and overclock to your heart's content. The stock 1333mHz is far from the limits of this memory. At the stock 1.8v, I raised the frequency to DDR3-1731. After raising the Vdimm to 1.86, I got to DDR3-1776. That's a 33% overclock, which I find very impressive. So is there anything not to like about the DDR3 ReaperX? Nothing that I could find."

GeForce Italia (Italy)
“After an uncertain start, DDR3 memory begins to spread and at the same time prices become more accessible. In the beginning, DDR3 memory was not enough performance, but now OCZ shows us that things are changing. With the ReaperX HPC DDR3 10666 memory, OCZ proposes to the public an excellent product with extremely low latency for its category."

Hardware Mag (Germany)
“The ReaperX 1333MHz 4GB DDR3 Kit from OCZ convinces with impressive design and cooling but more importantly with amazing performance. We managed to run them at 1T, with increased voltage which is no problem considering the EVP from OCZ meaning you won’t lose your warranty overclocking this kit. The performance is impressive, considering we even managed to beat several 2GB kit results. There is only one last thing to mention about the OCZ ReaperX 1333Mhz EB 4GB – Editor’s Choice!”

Xtreme Hardware (Italy)
"We're in front of a very interesting memory kit, both for its power and for how they look good. Thanks to the Enhanched Bandwidth this kit has excellent timings. The heat-spreader system works awesome, and keeps the memories cool even under overclocking. With the price so low, this kit will be good for everyone who wants a good 2x2Gb ddr3 kit and don't want to spend a lot of money. We've been very satisfied about this kit!"

Gamer-Network (Germany)
"Impressive overclocking results and low temperatures make this OCZ kit a true Overclocking King. The price / performance ratio is also excellent, last but not least we want to point out the great manufacture quality from OCZ once again. It deserves both our Gold and Performance award."
