Overclocking The Ryzen 7 2700X processor
Overclocking a Ryzen 7 2700X processor
On this page, I want to disclose what you can do in order to achieve an all-core overclock. We achieved 4200 MHz with the stock AMD cooler.
We settle at a multiplier of 42 and needed ~1.44 V on the CPU.
You guys know it when you're gonna tweak, always invest in good hardware. And that includes a proper MOBO/PSU/Memory and cooling), the cheaper motherboards often are not well tuned for enthusiast overclocking with fewer power phases. Please. never underestimate a good power supply and sure, proper processor cooling. Overclocking with a more core processor (doesn't matter if that is Intel or AMD) is more difficult than you expect it to be. Ryzen likes fast memory, so with this dual-channel (single rank) setup we really can recommend higher frequency memory like the 3200 MHz kits used. G.Skill also has a nice Ryzen optimized 3400 MHz kit (we use it here), only you can decide whether or not that is worth the extra dough though.
Most Ryzen Series 2000 CPUs to be able to hit 4.2 (with proper cooling). I expect most processors to hit 4.2~4.3 GHz stable on liquid cooling, and some really good parts maybe 4.4 GHz. That remains to be a bit of a luck of a draw really.
At 4200 MHz we finish wPrime in a 92 seconds (1024M / 16t). The Tdie max temp, however, reaches 80 Degrees C, surprisingly okay.
The Ryzen 7 2700X defaults at roughly 1800 points, the all-core overclock to 4200 MHz brings us towards 1893 points.
Above a thermal image of the VRM Area and corresponding temperatures - this is under full CPU load in overclocked conditions. M1 is the VRM heatsink under it, the MOSFETs, M2 are the solid chokes and capacitors. At M4 we are hitting an IC chip or Crystal, that's not part of the VRM!
