On all of overclocked systems the power saving features are disabled (ASUS EPU, C1E, C6, Cool'n'Quiet/Speedstep, Turbo) and power protection mechanisms (loadline calibration, over current protection, etc.) configured to allow the most amount of leeway before intervening. We started with the NB clock, as historically being a bottleneck for AMD processors getting more bandwidth from this should help overall performance. The ASUS Crosshair V Formula is well featured in that regard, so it's a simple matter to tweak the FX. However for simplicity's sake we kept the HT clock at reference 200MHz and used the multipler adjustment options to change other clocks.

AMD's platform allow for the HT base clock to be adjusted it's not locked down like Intels reference clock. We thank Peter Amos at AMD for the FX 8350, Darren McPhee at AMD for the Radeon Performance Edition memory, Dan Synder at Intel for the i7 2600K, and ASUS for the P8P67 WS Revolution mainboard.įor overclocking the FX 8350 there are three areas to consider: core speed, NB speed, and memory speed. Our platform and test comparison are driven by the hardware we have available to us. We're using the Link TitleAMD Radeon HD 7970 GHz Edition for graphics. Our platforms are configured to run at stock maximums where possible, configured with memory to match the supported controller speed rating, turbo enabled and power saving features enabled. The AMD side has the Phenom II X6 1100T, the FX 8150 and of course the new FX 8350. While we can disable HyperThreading and drop all core speed from 3.4 to 3.3GHz the stand-in is not exact because of two differences: the all core turbo is x35 instead of x34 and there's no way to disable the extra 2MB of cache the 2600K has over the 2500K. We have four platforms and five processors in our lineup today, not quite a complete sampling of all platform as we're missing Sandy Bridge E and Ivy Bridge, but representing the Intel camp is our trusty Core i7 2600K which is going to serve double duty as a pseudo Core i5 2500K, too.
