The Silver's Record: Sempron 140 at 5967MHz in wPrime - 1024m

It's been a whole month since we last covered single-core CPU records. Back then, I noted that Xeon processors had largely dominated this category.

It seems French overclocker The Silver heard my words, as he snatched gold in the wPrime - 1024m discipline using the once-popular AMD Sempron 140.

By the way, we have a review of this processor on our site. It's a shame it's from 2010 and can't boast much relevance today, but that's how it goes.

Back to the record-breaker.

To achieve a time of 12 minutes, 58 seconds, and 672 milliseconds, The Silver pushed the Sempron 140 to an astonishing 5967MHz at 1.744 volts (according to CPU-z). The processor's multiplier is locked, meaning the overclock was achieved solely by increasing the bus frequency.

This result is remarkably close to the maximum possible overclock of 6223MHz.

The processor was cooled using liquid nitrogen, and the record-breaking test bench consisted of the following components:

The surprisingly common GIGABYTE GA-MA790X-UD3P motherboard for the AMD AM3 platform
A single 1GB Crucial Ballistix Tracer DDR2 RAM stick
A 1000-watt Seasonic power supply

The graphics card used to secure the gold remains unknown. Most likely, a low-power placeholder like a GT710 or HD7730 was used.
