I decided to just test these modules alone, but did so at several different frequencies and timings. Overclocking memory on the 680i chipset is a bit different from most other systems, as there are many more options available to the end user. Users now have the ability to adjust the CPU and memory frequencies independently. These PC2-9200 modules were tested at the following settings/timings.
Linked, 1:1, 2.79 GHz, 1240 MHz 5-5-5-18 2T, 2.35v
Unlinked, 3.5 GHz, 1150 MHz 5-5-5-18 2T, 2.35v
Unlinked, 3.5 GHz, 1200 MHz 5-5-5-18 2T, 2.35v
Unlinked, 3.5 GHz, 1240 MHz 5-5-5-18 2T, 2.35v
Unlinked, 3.5 GHz, 800 MHz 3-3-3-3 1T, 2.35v
All tests were run at 2.35v, which is still within OCZ's lifetime warranty range. I found the max stable overclock for these modules to be 1240 MHz at the rated timings of 5-5-5-18 2T. Voltage increases did not help when trying to push the modules past this 1240 MHz frequency.
For benchmark testing, I will be using SiSoft Sandra XI Lite - Memory Bandwidth and Latency, Everest Home Edition 2.20.405 - Memory Read, Memory Write and Memory Latency, Super PI mod1.5 XS and MemTach v0.93 Alpha Analyze Tests. I will be conducting the benchmarks using my dedicated test system which consists of the following hardware.
Intel Core 2 Duo E6600
Zalman CNPS9500 CPU Heatsink
EVGA 680i SLI Motherboard
Two 8800 GTX cards in SLI configuration
74 Gb Western Digital Raptor 10k RPM HDD
Lite-On Optical Drive
OCZ ProXStream 1000w PSU
Mountain Mods Duality Case
The modules installed without issue and booted up at the advertised speeds. Continue ahead as we check out the testing results.
