Der neue Corsair 2700 wird ohnehin nicht mit einem 3500er mithalten können, d.h. 220 und mehr wirst Du vergessen können 
Zudem:
''Keep in mind also that all but some outdated DIMMs are using components that are running internally at 1.8V, anything beyond this will only be converted into heat. Along these lines, we found the best stability with the Mushkin PC3500 at 200 MHz 2:2:2 (running 2 x 512 MB in dual channel mode) at 2.6V. 2.7V or higher caused system instabilities.''
''The Corsair XMS 3200 CL-2, on the other hand would not run stable below a 2.7V setting. Among other things, the design of the PCB and the resistor network account for some of these differences as well. Bottom line is, though, that it is hard to justify anything beyond a real voltage of 2.75 V for both VDD and VDDQ. Contrary to popular belief, there is neither any gain in operating frequency nor in performance at higher voltages beyond 2.8V unless some really old components are used .''
