"This new 4GB kit offers impressive timings at frequencies up to 1066MHz, at a bargain basement price! We were able to reach a total clock frequency of 1162MHz, which is impressive for a 4GB memory kit. For 4GB of memory the OCZ DDR2 PC2-8500 Reaper HPC 4GB kit is incredible value. Over the past year DDR2 memory has become unbelievably affordable, making 4GB memory kits such as this OCZ example more than just a luxury item that everyone can afford."

Overclockers Club
"The OCZ Reaper HPC PC2-8500 memory performed well. I would recommend the OCZ Reapers to anyone looking for the best bang for the buck. With the unique HPC heatspreader you will not have to worry about the modules getting too hot.I know I am going to be using them from now on."

"Looking at the overclocking results at 5-5-5-15 we can't see any difference to 2GB Kits anymore which is impressive. This memory kit is especially interesting for 64bit users, also an interesting product for gamers and enthusiasts."

Bjorn 3D
"This is one of the highest clock speed 4GB DDR2 that is available on the market. What the OCZ Reaper brings to the table is that it is guaranteed to work at 1066MHz at 2x2GB dual channel mode, and it can easily achieve 2.1V. What is great about these sticks is that they are capable of running at the given speed and overclocked speed of 1120MHz at low voltage of 2.15V (well within OCZ's warranty specification), so you can safely overclock it and still maintain the warranty.

"The memory is definitely capable of exceeding it's rated specs. Given the complexities and obstacles associated with a 4GB kit, 1066 MHz is a worthy achievement in its own right. The 4GB Reaper kit remained completely stable throughout testing as well as passed several hours of further scrutiny. From 800 MHz 4-4-4-12 to 1150 MHz 5-5-5-15, you get sweet 2 x 2GB Dual Channel memory kit built with quality ICs backed by OCZ's Lifetime Warranty. Performance is top notch with excellent results for the most avid gamer or application guru. Vista users will also appreciate the larger capacity allowing their system to stretch its legs fully without worrying about system resources. This is the largest 4GB overclocking memory kit thus far I've had the pleasure of testing and now understand its hidden benefits. I highly recommend this kit the next time your seriously considering a DDR2 upgrade."

"During the real world results the OCZ Reaper PC2-1066 kit gaming performance felt smoother to me. Overclockers will appreciate and utilize the extra headroom DDR2-1066 provides. With the way memory prices the way they are, you can't go wrong with this memory kit. If you are in the market for a new kit of DDR2, OCZ's PC2-8500 4GB kit is the way to go!"

PC Assemblage (France)
"For those looking at frequencies, the OCZ kit is our winner and let's also emphasize it was the most efficient kit in terms of heat dissipation."

Modders Inc.
"The OCZ Reaper HPC DDR2 PC2-8500 modules performed to spec and did offer a little bit of overclocking. The cooler design is unique and will offer optimum cooling compared to the standard heat spreaders. Overall I am pleased with the performance and ease of use I experienced with the OCZ Reaper HPC modules."

Benchmark Reviews
"The 'Heat Pipe Conduit' adds that high tech look to give you that extra few points when it comes to bragging rights and the thick bolted together heatspreaders are second to none when it comes to good solid construction. I have not seen any other manufacturer build such a substantial heatspreader ever. All of this adds up to excellent cooling. The Reaper HPC Memory kit has proven itself as shown in the test results. Its performance is on par with other performance memory with similar specifications. This memory tested very well and has excellent performance and speed, matched with its cooling it should provide years of performance trouble free operation. The Reaper HPC held it's own against some stiff competition in the Corsair Dominators and in some cases surpassed them. I'm very impressed. It is a proven platform that offers a very high level of performance at a very reasonable cost."

Anandtech: System Building Guide
“This memory is rated at a fast 5-5-5 at DDR2-1066 and it performs at faster timings and lower voltages at slower speeds. Whether you use it as a stock DDR2-1066 memory or overclock it to its limits, this OCZ memory should provide the headroom you need to bring out the best in this system.”
