BL2KIT25664FN1608 Conclusion

Testing Methodology: DDR3 RAM

At Benchmark Reviews we need to test memory without adding any other factors to the results. While testing stock speeds is usually easy, it only gets more difficult when we want to add overclocked results. We need to make some changes to the BIOS values and test each configuration to ensure maximum stability. First, I set the values on the BIOS and run Memtest to check if the kit is stable or not. After that, I test with OCCT Perestroika to check if the CPU is stable along with the whole system.

Finally, Benchmark Reviews decides which frequencies are going to be shown in the graphics in order to leave the CPU factor outside of the equation. This way you'll probably see small differences between memory frequencies, latencies and voltage reflected on our charts without the CPU interfering in the results. Benchmark Reviews will use the following tests suites and applications:


Test System

  • Motherboard: ASUS Maximus III Formula P55
  • System Memory: 2x2GB Crucial Ballistix BL2KIT25664FN1608
  • Processor: Intel Core i7 860 with Prolimatech Megashadow heatsink
  • Video: ATI HD 5850 @ stock speeds
  • Disk Drive 1: Intel X-25M G2 80GB
  • Disk Drive 2: Seagate Barracuda 500GB
  • Enclosure: Sunbeam Ultra Tech Station
  • PSU: Antec Signature 850 watts
  • Operating System: Windows 7 Ultimate x64

With the ASUS P55 based motherboard we're able to choose very low vDIMM voltages, but unfortunately this kit wasn't done for Overclocking it seems. At 1.55v, the memory kit was very stable, but at 1.5v it showed some issues and resulted in BSODs. I always like to try using a Command Rate of 1T, but this kit refuses to work at 1T at any settings. Adding voltage or lowering the frequency didn't worked either, so, all the results shown will reflect the configurations said with a command rate of 2T. After testing and overclocking a little I find the kit was able to do the next configurations which Benchmark Reviews will use for the review:

  • 1333MHz 6-6-6-18 2T 1.65v
  • 1333MHz 7-7-7-20 2T 1.55v
  • 1600MHz 8-8-8-24 2T 1.60v
  • 1800MHz 8-8-8-24 2T 1.65v

I worry about the temperature of my processor; the temperature of my GPUs, and even the temperature of my chipset. I never worry about the temperature of my memory, and have yet to see any evidence that any memory cooling setups serve any function other than aesthetics. I'm hypocritical enough to want flashy-looking RAM while acknowledging that bare chips would work just as well.

That was my point at the final thoughts and the reason it didn't scored high at the end.
Actually, now that you've mentioned it David, as far as I remember memory heat sinks started some years ago with the purpose of hiding the ICs of each memory. I always took them away and added a fan. That worked much better than a plain metallic bar. I can't really see something useful unless for those curious about their whole system. I've never heard of heat problems with RAM yet (unless overclocking).

Sorry, I was responding to the Crucial rep's assertion that PC enthusiasts claim that system heat is a "constant concern." It is...for some components.

What the heck!
I'm looking to read more about your Crucial ram with the lights and when I click on a hyper link to read more it's a friggen Intel comercial???
What are you trying to sell here your ram or intel???
I'm shopping for ram and I don't want to see a comercial for another company's product!
