Both sets of DIMMs must be installed into memory slots three and four due to a clearance issue with the Swiftech Apogee Drive block/pump fittings. As soon as the system is powered on the red LEDs on the Ballistix Tracer begin to flash on and off in a pattern starting in the center of the module and alternating out towards both ends of the stick simultaneously. The frequency of the flashing indicates the utilization of the memory, and by the time Windows starts to load, the activity has pegged the LEDs with a near solid effect. The red LED lighting matches very well with the Cooler Master HAF 932 AMD Edition case.
The memory I'll be using to compare the Crucial Ballistix to is this smaller 2Gb kit of OCZ Platinum DDR3-1333, which uses timings of 7-7-7-20-28-1T via SPD, as shown here in CPU-Z.
The Crucial Ballistix DDR3-1600 defaults to the same 1333 (667MHz) speed when left to detect via SPD, although with much higher timings of 9-9-9-24-33. The Intel XMP profile reveals these sticks are rated to run at 1600 (800MHz) at 8-8-8-24-36-2T with 1.65 volts. In an AMD system these timings must be set manually in the BIOS. The only issue I ran into after configuring these is that the Bank Cycle Time (tRC) slipped to 35 even though I had it set to 36, however this is most likely a result of the motherboard BIOS and not the memory. As we will come to see next, this did not cause any problems during testing.
