The FX-9370 acted in all respects like the FX 9590 when it came to overclocking and reached almost as high, albeit using a bit more voltage to get the job done. As a slower chip out of the gate, there was more overclocking headroom available to improve performance, where the FX-9590 only had 368MHz worth of overhead. Ultimately, I had to settle for a thermally limited 5016MHz, or 616MHz bump, over the base clock speed of 4.4GHz. All other settings in the BIOS were equal to that of the FX-9590, but the FX-9370 needed 1.54v to break the 5GHz barrier. As far as looking for a lot of room on these chips, AMD found most of it when it binned these samples out. Both chips could easily boot to 5.2GHz and do screenshots, but for full-on testing and stability, I stuck with the numbers you see here.
