OCZ Reaper HPC Edition PC2-8500 2GB Kit (DDR2-1066)

Test Setup

Test Setup

For this review, we will test the performance of the PC2-8500 (DDR2-1066) version of the OCZ Reaper HPC Edition memory. These modules operate with SPD timings of 5-5-5-15 at 1066MHz and will be tested on a NVIDIA nForce 680i SLI test bed. Performance will be measured based on the memory default settings (SPD timings) as well as the best improved latency (OC timings) that we are able to achieve. The full specifications of our benchmark tests and parameters that will be used is listed below:-

The OCZ Reaper HPC DDR2-1066 memory is rated to run at 5-5-5-15.

  • Intel Core 2 Extreme X6800 processor
  • ASUS P5N32-E SLI Plus (NVIDIA nForce 680i SLI)
  • 2 x 1GB OCZ Reaper HPC DDR2-1066 @ 5-5-15 CAS 5.0 (SPD)
  • 2 x 1GB OCZ Reaper HPC DDR2-1066 @ 4-4-8 CAS 5.0 (OC)
  • 2 x 1GB AENEON XTUNE DDR2-1066 @ 5-5-15 CAS 5.0
  • 2 x 1GB Kingston HyperX DDR2-1066 @ 5-5-15 CAS 5.0
  • 2 x 1GB Kingston HyperX DDR2-800 @ 4-4-12 CAS 4.0
  • Seagate Barracuda 7200.10 200GB SATA hard disk drive (one single NTFS partition)
  • MSI GeForce 8600 GT 256MB - with ForceWare 162.18 drivers
  • NVIDIA nForce 9.53 driver set
  • Microsoft Windows XP Professional with Service Pack 2 (and DirectX 9.0c)

OCZ Reaper HPC PC2-8500 memory with SPD timing at 1066MHz.

Fastest latency timings achieved without going above the standard 2.35V range.

Additional Notes

  • Although OCZ lists the default voltage of the Reaper HPC as 2.3V, we found that our pair of memory operates with better stability at 2.35V. Since this is covered by OCZ's Extended Voltage Protection (EVP) scheme, we will consider it within its default parameters to continue with our benchmarks.


The following benchmarks are used in this article to gauge the performance of the OCZ Reaper HPC DDR2-1066 memory:-

  • BAPco SYSmark 2004
  • Futuremark PCMark05
  • SPECviewperf 10.0
  • Futuremark 3DMark06
  • F.E.A.R.
  • Unreal Tournament 2004
  • Quake 4
  • AquaMark3
