Test System & Settings
We’re testing Ryzen 3 1300X the same way that we tested the Ryzen 5 CPUs, using an inexpensive MSI B350 Tomahawk motherboard that sells for around $100. This motherboard does allow for overclocking as long as the CPU supports it. Spoiler alert: we got Ryzen 3 1300X up to 4 GHz in the German lab and 3.9 GHz in the U.S.. The systems stayed stable for prolonged periods of time at these levels.
One particularly interesting feature offered by MSI's B350 Tomahawk is a temperature sensor in the socket area. You'll hear more about this later, since we gathered some interesting measurements to compare against AMD’s Tclt values.
The B350 Tomahawk is a Socket AM4 motherboard based on the B350 chipset. It has four DDR4 slots and supports up to 64GB of memory. Our configuration only required two slots, yielding 16GB (2x 8GB of DDR4-3200). The motherboard has one PCIe 3.0 x16 slot, one PCIe 2.0 x4 slot, two PCIe 2.0 x1 slots, as well as two older PCI slots. There’s also an integrated 7.1-channel audio codec, as well as gigabit Ethernet, four SATA 6Gb/s ports, an M.2 connector, and the usual USB 3.0 Type-C and USB 3.0 ports.
