Crucial's latest addition to the Ballistix range certainly looks the part with its new design of heat spreader but when you get down to the nitty gritty, the performance of these new modules is pretty disappointing.
The most we could stably overclock them at was just 200MHz over the stock 1600MHz speed at 1800MHz, which is not what we have come to expect from the Ballistix range.
This is due to the fact that even to run at stock speeds the modules are on the power limit at 1.65volts while the chips themselves don't seem very keen to run at too high a clock rate.
On the other hand the hardware thermal monitoring and M.O.D (Memory Overview Display) Windows based software combination looks interesting and although it is at early stage in development seems to work well.
It'll be interesting to see if Crucial add the thermal sensors to the rest of the Ballistix range because as it stands it is only available on these modules.
As well as showing the temperature of the modules (which can be logged to a file) there's a settings page that allows changes to the time that the temperature chart updates and from Celsius to Farenheight.
There is also a SPD data page showing details of the modules which includes JEDEC timings and Intel XMP profiles.
Crucial's BL2Kit25664FN1608 is a well priced 4GB memory kit and the combination of the integrated thermal monitoring/M.O.D utility, although in its infancy is a neat touch especially if Crucial decided to add to the rest of the Ballistix lineup.
But, and it's a fairly significant but, don't choose this kit if you want to do some serious overclocking.
The major problem with this BL2Kit25664FN1608 kit is the limited range of overclocking options available.
This is something that you can't normally accuse the Ballistix range of, mainly due to the fact that running at 1.65v out of the box there's no where to go voltage wise which wouldn't be a problem if the memory chips themselves were capable of being tweaked at lot more than they are.
If you are looking for a stable memory kit which you can tweak slightly and monitor the thermal dynamics as you do it, then this is the kit for you.
Want serious overclocking potential then look to Crucial's competitor's or other modules in the Ballistix range.
