Overclocking the Ryzen 1700
The Ryzen 1700 I used for overclocking here today was supplied by AMD. I do however have a retail sample on the way as well. It will hopefully be here today so I can get it onto the same GIGABYTE X370-Gaming 5 for an overclock comparison. I however do not expect to see a lot of variance.
Talking to folks at AMD, I was told that these new Ryzen CPUs were not binned on speed, but rather on voltage, and it seems that Ryzen is getting very good yields that are very similar. Surely there are going to be variances when we are overclocking CPUs, but I do not feel at this time that we are going to see a lot of differences.
The two 1700X CPUs I have tested are identical in regards to overclocking performance. Those two CPUs were rock solid at 4.025GHz with 3000MHz and 3200MHz RAM. Both of these were at 1.4v vCore, 1.2v SOC, and 1.4v RAM. In fact, backing down on the RAM clocks did not give us any more headroom when overclocking at all. AMD got its IMC right! I am very sure of that.
The single Ryzen 1700 I have did not fare as well, but it was not far behind. The best I could get out of it and it remain rock solid was 3.966GHz with either 3000 or 3200Mhz memory, at the very same voltages above. It did however do this with water or good air cooling, the same as the 1700X CPUs.
Below is a screen shot of the 1700 running two instances of HandBrake encodings for over two hours. If it is not "real world" stable, this will break it.
I did push the vCore as high as 1.45v, which related to an actual variable vCore of 1.5v with CPU Load Line Calibration set to "Extreme" in the UEFI, but it netted me no more stability at the clocks I was working with. Given this is my only 1700, I did want to save it for later.
On water and good air cooling on an open bench we saw the package core temperatures reach a maximum of 75C.
The 1700 and 1700X CPUs are a bit more forgiving than the Intel processors we are so used to dealing with. These Ryzen CPUs do not BSOD or crash the system like we will see with Intel systems when we have pushed the overclocks a bit too far. Many times stressing programs like ASUS RealBench will simply "Halt," noting that an instability has been detected. The same with HandBrake. HandBrake will usually just fault to its "off" state and just stop encoding. Your mileage may vary, but that is what I have seen happening. Of course you can push the Ryzen into dicey territory as well where it will immediately fail as soon as it sees any type of load at all, but that generally happens right around the 4.05GHz mark with the three CPUs that I have tested.
