Settings & Overclocking
As with all memory reviews on Overclock3D the Cellshock DDR3 kit was subjected to a series of benchmark tests under several different configurations. The configurations used tested the memory's ability to run at high frequencies with stock timings, high frequencies with relaxed timings and also ensured that that the modules could run with 100% stability at their advertised speed, latency and voltage settings.
Stock Frequency & Timings
DDR3-1800 / 8-7-6-21 / 1.7v
Not only did the Cellshock PC3-14400 kit manage to run straight out of the box at its stock settings of DDR3-1800 / 8-7-6-21 without any additional tweaking, but amazingly it only required 1.7v. This is significantly less voltage than most other DDR3 kits we've tested recently, and will hopefully give the modules some extra headroom during overclocking.
Highest Frequency @ Stock Timings
DDR3-1922 / 8-7-6-21 / 1.8v
With the timings still set to their stock values, the maximum overclock obtainable on the kit was 961mhz (DDR3-1922). Interestingly the Cellshock kit did not respond to additional voltage as we'd anticipated, and the maximum voltage that we could use on the kit before experiencing stability issues was 1.8v.
Highest Frequency @ Relaxed Timings
DDR3-1964 / 8-8-8-25 / 1.8v
Relaxing the timings down to 8-8-8-25 saw the Cellshock kit hit a maximum speed of 982mhz (DDR3-1964). These results rank the Cellshock kit in the top two DDR3 kits we've tested on Overclock3D so far, and once again come within a whisker of DDR3-2000.
It is worth mentioning that obtaining this impressive overclock required the use of active cooling on the motherboards Northbridge chipset. Without this, the stock cooling on the P5K3 motherboard would have probably melted!
