Introduction & Specs
When it comes to PC Memory, Crucial are one of those companies that every man and his dog will have heard of. With roots stemming from Micron Technology - an OEM memory manufacturer with almost 30 years under its belt, there is no question that Crucial modules are designed by some of the most experienced engineers in the industry. More information on Crucial's history can be found over on their website, but here's a snippet of the best bits:
For nearly three decades, Micron has learned that when you make some of the very best memory in the world, lots of companies want it, from computer makers to wireless device manufacturers to printer producers. (And we're really glad that they do!)

But then Micron asked, well, what about the end user? What about the everyday folks who want to upgrade their existing systems with OEM-quality memory — the home desktop user, the IT network guy, the student notebook user? Why don't we offer our memory to the public, at factory-direct pricing?

So in 1996, Micron responded to a growing demand for high-quality memory upgrades among end users who wanted the best possible performance from their systems. Micron launched Crucial Technology in September of that year, and for the first time, end users had the opportunity to buy directly from the manufacturer the same memory modules bought by the world's major OEMs for original installation in their systems.
Back in April 2007, Overclock3D was fortunate enough to test Crucial's high-end DDR2 based PC2-8500 Ballistix kit. Showing extremely good performance combined with no-nonsense looks, the kit managed to obtain our Recommended award. This certainly wasn't the first time we'd been impressed by the Ballistix either. Rewind a further 6 months back in the history of Overclock3D memory reviews and we come to the Ballistix PC2-6400 kit that left our labs with both Editors Choice and Value for Money awards.
Today we're back once again, but this time taking a look at Crucial's latest DDR3 Ballistix kit. With a stock speed of PC3-12800 and default timings of 8-8-8-24, the kit may not sound anything special when compared to some of the top-end kits by other manufacturers. However, our experience of previous Ballistix kits tells us to reserve our judgements until after the testing. So with this in mind let's take a look at some of the vital stats of these modules from Crucial's website:
What is Ballistix memory?
The Ballistix line is specifically built for performance enthusiasts who want to push the performance envelope without worrying about data loss or corruption, mysterious intermittent errors and display problems, or worse — the dreaded BSOD! The Ballistix line of high-performance memory modules features advanced speed grades, low latencies, and integrated aluminum heat spreaders.

I have to say that I was pretty disappointed by the information available for these modules. It seems that Crucial's website has recently undergone a face-lift and some of the vital information such as warranty duration/terms have not been included. In addition, many other manufacturers also list the maximum voltage that can be used on their modules without risk of voiding the warranty. By omitting this information, Crucial could well be turning a way a large portion of the overclocking crowd.

One thing I've always commented on in previous memory reviews from most other manufacturers is the over-use of the clear plastic blister style packaging. Not only does this method of packaging provide very little protection for the modules during shipping, but it also raises concerns regarding ESD damage. As we've seen in previous reviews, Crucial have always put protection before appearance - and it doesn't look like anything has changed with their DDR3 kits either...

Consisting of a single walled plain cardboard box sealed with a large Crucial sticker, the outer packaging of the Ballistix kit gives no indication as to what modules are contained within. However, on opening the box we can see that Crucial have individually sealed the modules in their own anti-static bags - each complete with their own barcode labels.  This could possibly signify that the boxing of the modules is performed at the final stage of the picking process when you order a kit directly from Crucial's website.
The Ballistix DDR2 kits have always been instantly recognisable by their trademark Gold painted Aluminium heatspreaders and Black PCB's (with the exception of the "Ballistix Tracer" series). However, many manufacturers have changed the look of their DDR3 modules to help distinguish them from their elder DDR2 counterparts. Have Crucial followed suit? Let's find out...

At a glance, the Ballistix PC3-12800 DDR3 kit looks almost identical to its DDR2 predecessors. However, on closer inspection we can see that Crucial have removed the clips at the top of the heatspreaders, thus relying entirely on sticky pads to keep everything in place. Other small changes include the addition of "DDR3" text below the Ballistix logo, and a slight change to the Crucial logo at the left of the modules. Overall, not much of a noteworthy change in all honesty.

Removal of the heatspreaders certainly isn't for the faint of heart, and actually required the use of a blowtorch to heat the adhesive thermal pads up to a point where they could be removed without pulling the memory IC's off with them. Interestingly, Crucial have decided to print over the Micron logo and IC serial numbers with a large Ballistix logo. This prevented us from obtaining a definite identificaiton of the IC's modules, but an educated guess would be that Crucial have used the highly overclockable D9GTR IC's.

Settings & Overclocking

As with all memory reviews on Overclock3D the Ballistix PC3-12800 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 with stock timings, high frequencies with loosened timings and also ensured that that the modules could run with 100% stability at their advertised speed, latency and voltage settings.

Crucial have always been a "safe-bet" when it comes to modules that work flawlessly out of the box and the Ballistix PC2-12800 kit is certainly no different. Even with a fairly low stock voltage of 1.8v, the kit managed to pass several hours of Prime95 stress testing at 8-8-8-24 timings on our Asus P5K3 test bed. This is very good news for those of us who are looking for a DDR3 memory kit that can installed and forgotten about, but the Ballistix range is all about overclocking! So let's get down to the nitty gritty and see what this kit is capable of...
Stock Frequency @ Lowest Latency
DDR3-1600 / 6-6-6-12 / 2.1v
CPU-Z Lowest Latency CPU-Z Lowest Latency
Bumping the voltage up to 2.1v allowed for some serious tightening of the timings on the Ballistix kit. Both the CAS# Latency, Delay and RAS# Precharge effortlessly came down by 2 clocks, with the Cycle Time also accommodating a considerable reduction down to 12 clocks. This is actually the tightest timings we've managed to obtain from any DDR3 kit tested on Overclock3D so far (Previous kits have only managed 6-7-7-12), and certainly goes to show that the Ballistix kit has been given quite conservative stock timings.

With most of the other DDR3 modules we've tested recently hitting close to DDR3-2000 I was certainly expecting something very similar from the Ballistix kit. However, after several hours of tweaking, trying the memory in different slots and applying extra cooling to the modules, the highest overclock I was able to obtain at the 8-8-8-24 stock timings was DDR3-1820. This certainly isn't anything to be sniffed at; as it's still a good 110mhz increase from the stock 800mhz speed, but unfortunately it falls just a little short of some of the other DDR3 kits tested on Overclock3D recently.

Crucial have always had a reputation for memory that works straight out of the box and the Ballistix PC3-12800 kit is certainly no different. Unlike a few of the DDR3 kits we've tested recently the Ballistix was 100% stable at stock speeds without the need to tweak any memory sub-timings or voltages, and I'm pleased to say that we managed to get through the whole review without pulling our hair out once!
It has to be said that the stock 8-8-8-24 timings of the kit are quite loose by the standards of many other DDR3 kits on the market. However this certainly seemed to give us a lot of headroom during tweaking with the modules managing extremely tight 6-6-6-12 timings at 2.1v. This is actually the tightest latency we've managed to get out of any DDR3 kit so far on OC3D  and should certainly raise a few eyebrows among the "DDR3 latency" critics.
Unfortunately, overclocking the modules didn't yield quite as impressive results with the modules topping out at DDR3-1820. While a bump of 110mhz over the stock speed certainly isn't anything to be sniffed at, it does fall slightly short of other PC3-12800 kits we've tested in the past that have almost managed to break DDR3-2000.
Back on the upside, the Crucial Ballistix PC3-12800 kit is available at many retailers for the highly respectable sum of £154. While this is still a fair bit higher than your average 2GB DDR2 kit, it's certainly more within the reach of the average overclocker.
