Overclocked Pre-production Units

We have two pre-production NiuBi Personal Cloud 1 (NB-PC1) units up and running (overclocked, no less)! Check out the following images. As you can see, the pre-production units have inexpensive, unfinished, steel side plates — the aluminum side plates went off to be anodized earlier today. Production assembly of the PCBs starts tomorrow.

Overclocking and Benchmarks

The two pre-production NB-PC1 units are working well overclocked to 2 GHz. Testing reveals that even higher clock speeds can be achieved.

We get the following benchmarks using openssl, as described at https://wiki.openwrt.org/doc/howto/benchmark.openssl:
