Turn off the turbo core entirely, as keeping it active will cause instability in any overclocking attempts and drastically alter voltage levels.
I think I didn't win the silicon lottery heh. 4.9 GHz with 1.60625V P95 over 3 hours and AVX stable for 10 runs. 280mm AIO rig.
I doubt I can upgrade my FX 4350 chippy to 5.5 GHz on a custom loop, probably maxing out at 71°C.
If you have an FX chip hitting 4.9 GHz with less than 1.5V stability, you're likely getting a gold standard chip.
Have you tried the AVX version of IBT? Aim for stability and most people would agree that after 10 standard runs with AVX stable, you'd be solid, even with a small extra 100mV.
That's the kind of stability we're talking about. AVX doubles your FLOPs in parallel tasks.
Through several trials I've discovered it can operate smoothly at 4.9ghz with DDR3 2400 memory running at maximum capacity—except during the hottest months. On the warmest days the water temperature climbs to 44°C and pushes the CPU to 71°C. According to AMD, it should handle a bit more heat than the official specs, but around 71.5°C with a vCore near 1.505. My radiator functions like a 120mm unit, though the half-inch tubing reduces pressure drop slightly. It performs better than a standard 120mm but offers less surface area than a full 240mm model.
We'll hold off until the Ryzen and X370 AM4 boards arrive before reusing the cooler blocks. Then we can push them to higher speeds. Better IPC, less power consumption. Pairing them with an RX 480 or RX 490 would likely give you a powerful setup for 1080p. We might be ready to invest more in Intel if it turns out to be a real improvement over the Zen chips.
