Crucial Ballistix 1333

Crucial has proven to be a tough competitor in the memory market. Let’s take a peek inside and find out why that is so.


Ever since the introduction of Tri-Channel DDR3 memory, we have been seeing a whole slew of different memory types and speeds. But not all memory is created equally. What makes one memory better than another is the ability to overclock and maintain that speed better than the other types of memory. Crucial has proven to be one of these memory manufacturers.

Today I bring forth the Crucial Ballistix 1333MHz memory. Let’s go see how much abuse these sticks of memory can take before they start turning different colors.

Crucial is one of those types of companies that keeps their packages quiet simple and plain looking. It’s nothing extravagant, just simple. This is the top of the memory packaging.

On the backside of the packaging Crucial gives us a quick understanding on how to use the memory and also what is required for triple channel memory.

Yep, they are orange on a black PCB. The signature color Crucial has been using for years.

Various close up images of the memories. If you notice Crucial doesn’t use a clip on style heat spreader, instead these heatspreaders are just held on into place by a thermal tape (I did not tear these memories apart to verify that).


Now, installing memory has not changed since the introduction of PC66MHz SDRAM memory. Just line up the memory modules to the proper memory slots on the motherboard and push down gently till they lock into place.

I decided to change a few things up this turn. Instead of using Windows Vista 64 bit OS for testing, I used Windows 7 Beta 7048. I also threw in PC Mark Vanatge in the mix. All I used on this benchmark was the memory testing and the graphics testing (no real point on using the entire suite for memory). As always, I ran each benchmark a total of three times randomly, making sure of no erroneous readings and my scores were consistent with one another. I only tested the Corsair’s default speed of 1600 MHz, as well as the two XMP profiles that the Crucial Ballistix had. The overclocked frequency of 1718 MHz is for a reference and to give an idea of the performance gain once you overclock your memory. Being my motherboard does not have a memory divider of anything higher than 8 (default) I was forced to use FSB to push the memory speed up higher. I did use both of the memory’s XMP profiles for default speeds, The ASUS Rampage II GENE would adjust the FSB and the CPU multiplier to accommodate.


Overclocking the Crucial Ballistix was extremely easy. I first tried to use the XMP profile of the memory of (7-7-7-24 timings) and increase the FSB to 215 x 8 giving me a 1718 MHz overclock on the memory with a timing set of 7-7-7-24. Well, I found out real quick in Windows 7 that these were highly unstable. So, I re-entered my BIOS turned off the XMP profiling and adjusted the memory timings to 8-8-8-24, left the FSB @ 215 with a 8 divider, and had a go with that. Long story short, these sticks were perfectly stable. After running all of my testing, I went back into The BIOS and started looking at the XMP profiler. The BIOS was listing two XMP profiles. Profile 1 had a memory timing of 6-6-6-18 and Profile 2 used the rated timings of 7-7-7-24. So, I tested both profiles. The only screen shot I am able to show off is the overclocked screen shot. I had a few other screenshots showing that I was using the default XMP profiles, but somehow managed to lose them .

Not bad for 1333MHz memory. Darn near a 400MHz gain with just an adjustment of the timings.



Starting off on the benchmarking software is SiSoft memory bandwidth. It is only natural for the Corsair to come out ahead of the Crucial memory because of the higher memory frequency of 1600MHz vs. the 1333MHz. When looking at the two different XMP profiles 1 & 2, we see having  tighter memory timings does make a slight improvement, but it’s not enough to be concerned with.


Here are the latency results. Between the two XMP profiles, the memory having the best timings (tighter) comes out ahead. Also, I should mention that having a higher overall memory frequency makes an even a bigger difference.



Now this is strange. For some weird reason, wPrime prefers having a lower timing than having a higher memory frequency while the CPU is at default core speed of 2.66GHz.



Same story as wPrime testing. The memory with the tighter timings came out ahead over having a higher frequency while the CPU is at default speed of 2.66Ghz.



During Everest testing, having the highest possible memory frequency comes out with the highest possible memory bandwidth.


Now in the latency testing, the Crucial 1333MHz memory, while using the XMP profile two, and the Corsair while running at 1600 MHz have roughly the same latency.



During the memory testing, having an overall tighter timings performed better than having a higher memory frequencies. But again, this is only when the CPU is at its default frequency of 2.66GHz.


Once again, Crucial Memory has proven to be a tough competitor in the memory market. It is always hard to gain a few extra MHz with memory in general, especially when you are already pushing that envelope of high frequencies. With the several sets of Crucial memory I used over the years, I have never been disappointed with the performance of this companies memories. Crucial has always been on of the forerunners of performance and stability.

Having the ability to almost gain an extra 400 MHz on memory with just an adjustment to the memory timings, is outstanding. Unfortunately I am unable to find these sticks on sale from the web, but however did find these for sale at Crucial’s website and they have these listed for around $219 USD. This is more then a fair price to pay for such a great overclocking set of memory sticks.

We are trying out a new addition to our scoring system to provide additional feedback beyond a flat score. Please note that the final score isn’t an aggregate average of the new rating system.

  • Performance 10
  • Value 9
  • Quality 9
  • Warranty 10
  • Features 9
  • Innovation 9


+Great Overclockability

+Good performance to timings ratio

+Good Pricing


The white sticker on the signature orange heat spreader mars the look of these sticks.

Final Score: 9.5 out of 10 and the Bjorn3D Golden Bear Award.
