With the EK PRedator 240 Liquid cooling kit we hover in the 65 Degrees C range under full load. With the ASUS board we can advise you to leave CPU voltage at AUTO. We dropped to 4.1 GHz on all eight cores. Yet we need additional tweaking to be 100% stable and to be able to benchmark intensively. We can boot into Windows and run a simple test at 4200 MHz just fine. With the limited time available we tried some overclocking. If your memory should not be compatible, you can of course simply enter them manually as well and not use the D.O.C.P profile. You can also find the recommended DDR4 voltage on the sticker of your DIMM modules alongside all optimal timings.Īlso in DRAM timing control you will notice the most important memory timings preconfigured. Once you've applied this your DIMM voltage should have increased to 1.35 Volts (if not set it manually as we really can recommend that as stable voltage). Standard will activate the memory tweak at close to 3000 MHz. Most motherboard partners will label this as XMP, but since that is an Intel branded name for pre-defined SPD memory profiles just go to the Ai overclock tuner and select a D.O.C.P stage. Ryzen likes memory bandwidth, so with this dual-channel setup we really can recommend higher frequency memory like the 3000 MHz kit used. Basically this just sets the multiplier at 40 and disables XFR etc. You can now hit save and exit and you are done. To set the processor to 4 GHz (all 8-cores) just go to the Extreme Tweaker menu and select your profile. Now, with the ASUS motherboards you'll have tweaked options available at the press of a button.
During our measurements by trial and error we found that at 1.375~1.425 Volts you will end up at roughly 4.1~4.2 GHz (that is on all eight cores!).
The Ryzen 7 1800X has a base clock of 3.6 GHz and a boost frequency of 4.0 GHz.
You can also use AMD's software tool of course. Overclocking 8-cores on a high clock frequency is a tough job, but can be managed relatively easily from the BIOS. Both brands end in the 4.2, maybe 4.3 range, again that is similar with Intel processors as well.Ī bit of a mess, but that's what an overclocking table should look like -) We use the new Ryzen compatatible EK Predator 240 here. Overclocking with any 8 or more core processor (doesn't matter if that is Intel or AMD) is far more difficult than you expect it to be. Also get yourself a good power supply and proper processor cooling. First tip, always invest in good hardware by the way (MOBO/PSU/Memory/Cooling), the cheaper motherboards often are not well tuned for enthusiast overclocking. We're keeping things relatively simple. We need to take a couple of steps if we want to overclock.
With so many cores in the system we cannot resist overclocking.
