When it came time to overclock the processors, both of these SKUs really delivered more than I was expecting from them, especially from the 3.3GHz-rated FX-8370E. Both chips eagerly approached the 5GHz realm to compete on an almost level field with the pricier FX-9590 and FX 9370. First up was the FX-8370E, a chip I felt was going to be the weak link, but turned out to run at 4.99GHz with 1.5v applied in the BIOS while running the memory at over 2400MHz and hyperlink speeds above 2600MHz. Pretty stout for a supposedly non power-hungry chip. One thing that seemed off was that this chip would never heat up while running through IBT or the AIDA64 stress test. There was movement, but it would just never top 55 °C. On the other hand, the FX-8370 did exceed the 5GHz mark, matching the overclock of the FX-9370 of 5.015GHz with 1.48v set in the BIOS, but showed a bit more temperature scaling with its 125W TDP. Still not enough to throttle during the overclocking phase of the testing, but enough to get close. To get 1.6GHz out of the FX-8370E and just over 1.0GHz out of the FX-8370 shows that you can still have some fun and significantly increase the performance of the latest AMD FX processors.
