Phenom II 955 BE or FX 4100
Hello... I've found components to build a full system including an M5a88M motherboard (AM3+ socket) and either a Phenom ii x4 955BE or an FX-4100 (true Bulldozer). Both offer overclocking potential. I'm curious which one would perform better.
I'm aware this board supports FX processors, as I previously overclocked a 6-core FX-6300 to 4.4 or 4.5G—though at 4.5 it would throttle during video encoding due to VRM overheating. I believe the 4-core FX-4100 should easily reach 4.5G, possibly even higher.
I recall needing FXTweak to disable APM because the BIOS handled it poorly, and Windows 10's power plans resisted changes, forcing me to run it every time I did processor-heavy tasks to avoid throttling. I prefer running the Phenom II, trusting the BIOS will disable APM properly, but I want to know if I might be sacrificing performance for that stability.
For the Phenom II x955BE, I expect an overclock around 3.8G, though I'm not sure. What should be considered a safe maximum voltage? This board includes an LLC, though its limits are somewhat restricted.
I've always thought Phenom II offers better IPC than Bulldozer, with four true cores versus shared resources in the FX BD modules. I’m unsure which configuration—four BD cores at 4.5G or four PhII cores at 3.8G or above—will deliver better results.
Appreciate any advice or helpful links!
I recommend getting the Phenom. In threaded work, both options perform well, but the FX version might be slightly quicker. However, for other tasks, the Phenom will be significantly faster and more stable. I own an FX-8120, and its single-core speed was clearly lacking, even though it managed to outperform a higher-clocked i5 during rendering.
