For carrying out the DDR2 memory benchmarks, we turned to our usual i955X candidate -- the Abit AW8. Below is the rundown of system components used during the benchmarking process.
|Processor:||Intel Pentium D 820 (2.80GHz)|
|Motherboard:||Abit AW8 (i955X + ICH7R)|
|Memory:||2 x 1GB OCZ DDR2-1000
2 x 512MB GeIL DDR2-800
|Graphics Card:||NVIDIA GeForce 6800GT 256MB|
|Hard Drives:||Seagate 160GB SATA2 7200.9|
|Optical Drives:||Lite-On 16x DVD-ROM|
|Power Supply:||Sytrin Nextherm PSU460 460W|
|Operating System:||Fedora Core 5|
|Linux Kernel:||2.6.16-1.2096_FC5 SMP (x86_64)|
|GCC - GNU Compiler:||4.1.0|
|Graphics Driver:||NVIDIA 1.0-8756|
For benchmarking the modules, the Linux slab of programs consisted of Enemy Territory, Doom 3, LAME, FreeBench, and RAMspeed. This article also serves as our first Fedora Core 5 memory review. As always, the memory stability was largely answered through running memtest86+ v1.65. Below is the rundown of CPU and memory settings at which the OCZ Technology PC2-8000 Platinum XTC EL was tested, as well as a comparison GeIL 2 x 512 MB DDR2-800 kit.
2800MHz (200MHz x 14) - DDR2-667MHz @ 5-5-5-15 - 1.90V
2800MHz (200MHz x 14) - DDR2-800MHz @ 5-5-5-15 - 2.00V
3220MHz (230MHz x 14) - DDR2-920MHz @ 5-5-5-15 - 2.20V
Crucial Ballistix DDR2-800: 2800MHz (200MHz x 14) - DDR2-800MHz @ 5-5-5-15 - 2.00V
While the OCZ2P10002GK part is rated for DDR2-1000MHz at 5-5-5-15, using the Abit AW8 we were unable to attain these frequencies using the Abit AW8, for which is the basis of a majority of our current and past DDR2 memory tests. However, we had also installed the OCZ memory inside of an Abit AW8-MAX, which is similar to the AW8 vanilla with the exception of a few alternations and extra ASICs. With the AW8-MAX setup, we had no problems reaching DDR2-1000MHz with 5-5-5 timings and a Pentium D 820 running at 3.50GHz. Even on air-cooling, we were able to push this memory a bit past 1.00GHz, but not by far.
