As with all DDR2 reviews on Overclock3D the Ballistix modules were subjected to a series of benchmark tests under several different configurations. The configurations used tested the memory's ability to run at high frequencies, tight timings and also ensured that that it could run with 100% stability at stock settings.
DDR2-1066 / 5-5-5-15 / 2.2v
It's an unfortunate fact that some memory modules we've tested here at Overclock3D in the past haven't even been able to run stable at stock settings. Sometimes this is down to an incompatibility between the motherboard chipset and memory IC's, and other times the modules just havent been tested extensively at their rated speed. With this in mind, the first test we perform on any modules passing through the OC3D labs is their ability to run at the settings specified by the manufacturer.
I'm pleased to say that the Crucial Ballistix PC2-8500 kit passed the stock testing with flying colours, managing to run at 5-5-5-15 / DDR2-1066 with the rated 2.2v.
DDR2-1066 / 4-4-4-6 / 2.35v
Increasing the memory voltage to 2.35v allowed the timings to be tightened to a very respectable 4-4-4-8 while still running at DDR-1066. These tighter timings should offer a slight performance boost over the stock settings as I'm sure we will see over the next page.
Attempting to tighten the timings further than this proved unsuccessful regardless of how much extra voltage was used.
DDR2-1220 / 5-5-5-15 / 2.35v
One of the most important factors in purchasing RAM modules for most PC enthusiasts is how far they can be overclocked. Previous Crucial Ballistix kits we've tested have proved to be very good in this regard, and I'm pleased to say that things haven't changed with their PC2-8500 kit. Managing an impressive 14% overclock up to 610mhz (DDR2-1220) from the stock 533mhz frequency with only 2.35v, the Ballistix kit should certainly appeal to the overclocking crowd.
