Andy van BXB heeft een review geupt van de Powerleap socket370 riser card met dual Celeron jumper. Hier's de soep:
I tested on the Shuttle HOT-649a board, a motherboard which provides a limited ability to alter core voltage (up to 10%). Pluging in both convertors and jumpering to 2.2v for 504Mhz operation (4.5 x 112) worked perfectly,athough only 1 CPU was detected, which I soon discovered was done to one of the Powerleap convertors arriving dead on arrival (tut tut). Substituting one of my own modified boards and everything worked just fine, with the the voltage regulator of the HOT-649a reporting 2.2v for Slot1a and 2.0v respectively. So the convertors work as advertised, and more importantly, dual SMP operation from a pair of Celerons is now trivially easy. The voltage tweaking abilities is very welcome. Most PPGA Celeron 300'a work just fine at 2.0v at up to 464Mhz, but 504Mhz requires 2.1 or 2.2v (and even then you need a little luck - most Celerons won't run stably at 504Mhz).
