Look again at these modules!!!
The Speed Premiums tested have had a change in the ICs and now use Winbond UTT (UnTesTed) chips which are showing up all over the place. You can tell them appart from the sticks using the prior ICs not only by doing a visual, the new ones look like the bh-5/bh-6 of old, but also by the parts number on the stickers attached to the modules.
The ones tested in this review end in the coding AADT, the new ones use the coding ending in AA4T, (notice the D vs the 4). This code change is also printed on the ICs themselves, where the mfg. date is printed on the ICs, the old ones have the date (YYWW) plus the letter D, the new ones follow the Year/Week info with the number 4. An example of the old would be 0443D, like the modules used in this review and the new ones will look something like this...04514.
These new ICs, while showing no significant differences at default voltage, will scale through the roof when shot with extra voltage and perform very similar to the new line of extreme voltage memory from OCZ. In fact, there is much speculation that these same chips are used my OCZ to make their eXtreme Voltage series ram.
These sticks, with the new modules are hitting outrageous speeds of 255-275 at 2-2-2-x timings on both Intel and A64 systems. The only drawback is that you have got to be able to provide them with voltage in the 3.2v-3.6v range in order to get them to perform like this.
If you think these are not good overclockers....think again!
