OCZ Reaper HPC PC2-8500 2GB DDR2 Kit
Published: 30th April 2007 | Source: OCZ | Price: |Introduction
Heat has always been one of the largest limiting factors in PC enthusiasts quest for the ultimate overclock. Components such as CPU's, Graphics Cards and Memory all produce increased levels of heat when using extra voltage to push components to their limits. Until recently, one of the most common ways to disperse this heat was using a heatsink and fan, or in the case of memory modules - a heatspreader.
The heatspreader has been used on memory modules for several years, but has always been subject to criticism by many enthusiasts who believe that their design does more harm than good, trapping heat rather than dispersing it. There is certainly a level of truth in this statement, as many heatspreaders use low conductivity materials and have flat surface areas - all of which hinder the convection of heat into the surrounding air.
One of the more recent methods of removing heat from computer components is using heatpipes. This method uses pipes filled with a small quantity of liquid that evaporates when heated, taking the heat away from the surface. Once the vapor has cooled, it returns to a liquid, falls back down to the heat source and can begin the whole process again. This method has proven to be extremely effective and has recently been used in many award winning CPU heatsinks. For this reason it's no surprise that OCZ, one of the greatest innovators in the DDR memory market has used this very cooling method on their latest Reaper HPC DDR2 modules.
The following information has been taken directly from OCZ's website:
|The Reaper HPC is an innovative cooling solution developed by OCZ to effectively minimize heat produced by high-speed memory. As heat rises into the thermo-conductive copper heat pipe conduit, it is dissipated through the strategically-placed compact aluminum fin array. By guiding performance-robbing heat away from key memory components, the unique Reaper HPC design helps facilitate improved overclocking performance, while improving longevity and stability of the modules.|
The first modules to be incorporated with the new Reaper heatsink are rated at 1066MHz and run at CL 5-5-5. Featuring an EPP (Enhanced Performance Profiles) programmed SPD, PC2-8500 Reaper HPC modules will immediately boot at the rated specs on the latest generation of NVIDIA® SLI™ chipsets. Although the OCZ Reaper HPC series was coined for enthusiasts, EPP eliminates the need for manual configuration and makes memory optimizations a household item for the complete range of consumers looking to maximize system performance through overclocking.
As part of OCZ’s line-up of premium memory, PC2-8500 modules are backed by a Lifetime Warranty and industry-leading technical support.
• 1066MHz DDR2
• EPP 5-5-5-15 (CAS-TRCD-TRP-TRAS)
• Available in 2GB (2x1024MB) Dual Channel Kits
• OCZ Lifetime Warranty
• 2.3 Volts 240 Pin DIMM
• Reaper HPC Heatsink*
• EPP-Ready 2.35V EVP**
* The Reaper HPC series uses heat pipe technology to rapidly remove heat from the main body of the memory modules and conduct the thermal load to the extended radiator fin array. The addition of the extended fin array nearly doubles the total surface area available for heat dissipation while the heat pipes warrant near isothermicity throughout the entire design. The result is a doubling in effective heat dissipation at equal delta t or, in real systems, a significantly lower operating temperature of the memory modules.
**OCZ EVP (Extended Voltage Protection) is a feature that allows performance enthusiasts to use a VDIMM of 2.35V without invalidating their OCZ Lifetime Warranty.
OCZ have always catered for the overclocking community, and it's great to see that there's been no change of ethics in their latest Reaper series. All Reaper modules come complete with a lifetime warranty that covers overclocking and running the modules at up to 2.35v.
Interestingly, the stock voltage (2.3v) for the Reaper kit is a tad higher than most other PC2-8500 kits we've reviewed recently. This could pose problems for people with non-enthusiast motherboards that may be unable to provide this kind of voltage to the memory slots. If you are planning on purchasing a Reaper kit, it would certainly be worth checking in your motherboard manual for available voltage options first.
Overclockers will be delighted to hear that the Reaper modules are based around the highly favorable Micron D9 (D9GMH) IC's. These have performed very well in previous reviews, and I'm sure the heatpipe cooling will help us push them to their limits later on in the review.
