RasberryPi reach 1.5Ghz overclocking, stopped by software limitation

, , Leave a comment

Who would ever think to take a 25USD device (RasberryPi), replace the power delivery circuit with an eVGA EPower that cost about 4 times more, cool the SoC with a sub-zero system and push s much as you can.

That was the idea rsnubje (best overclocker in the Netherlands) put into action. The BCM 2835, an ARM-based SoC from Broadcom was pushed to more than double of the default speed (700Mhz), reaching 1.5Ghz.

Interesting point is that rsnubje hit… a software limit and not the hardware limit. ARM-based SoC can be very interesting for overclockers as the ecosystem is different from the PC ecosystem, you cannot buy the SoC and plug on a board, they are always part of a complete system.

To gauge the performance increase, we used the Java based HWBOT HWBOT Prime benchmark, which completed with a score of 795.18 pps, a world record. Interestingly, this performance approaches that of Intel’s slowest Atom processors.

In order to see if we can pass the 1.5 GHz barrier, we are talking with the Raspberry Pi’s software developers.

As stated this seems to be a software limitation and not the hardware limitation, looking forward for more accomplishment in the near future.
