Ryzen 1700 oc
Ryzen 1700 oc
I'm trying to boost my Ryzen 1700 CPU on the B450 Tomahawk board, aiming for 3.6 or 3.7. I've increased the multiplayer settings but am unsure about setting the voltage manually or overclocking it. Do I need any additional information?
A 3.6 speed should be quite achievable. Keep vcore on auto, just adjust the multiplier. Perform a test on your system at stock levels. Prime 95 small ffts will suffice. Execute Prime and observe the CPU temperatures. They should stay below 80°C. Ideally, they shouldn’t exceed around 70°C at stock. After measuring the temps at stock, return to BIOS, modify the multiplier, and restart. Run Prime once more to verify stability. If temperatures exceed 80°C, reduce the overclock or replace the cooler. If everything works well and stays within limits, you can experiment with voltage. Set a vcore around 1.3V, which will lower heat compared to auto settings. After changing the voltage, repeat testing with Prime to confirm consistency.

I attemped this a 1700 a while back and wasn't able to get higher than 36 and the screen would just go black. I'm used to intel and a blue screen when reaching instability but this never happened, even after a bios update. The only way to resolve this was to do a cmos reset on a MSI B350m Bazooka motherboard. Many people will tell you the stock cooler is fine, but based on my experiences I couldn't disagree more. I have purchased a the AM4 noctua cooler Noctua NH-U12S SE-AM4 and hopefully I can reach closer to 4ghz, however I suspect the motherboard might not be able to achieve it.
I have a 1700 at 3.8 GHz.
My thoughts on this are:
Don’t exceed 3.8, you’ll need significantly more voltage for even a small speed boost.
Vcore varies; I’d never set it on auto for overclocking. It can both damage your CPU and cause instability (since auto is essentially the motherboard guessing).
Vcore should stay below 1.35V if you want safety (assuming good temps).
There’s a difference between 3.2 and 3.7, it’s not huge but there is one.
If you’re unsure how to do this correctly, study online first—this info exists. If you’re careless, you’ll be the only one to blame.
6. The standard Vcore tends to perform worse for Ryzen CPUs (first gen) than manually adjusting it. My setup would jump to 1.46Vcore on auto, which is risky long-term.
Would you suggest using 3.6, trying the v core at 1.3v, and keeping the rest on auto? Thank you for your response!
While I concur with some of your observations, others are not correct or could be misleading. Going above 1.35 is completely acceptable. My VID for my 1600x is 1.375. I maintain a vcore at 1.3, which keeps the OC stable at around 3.9ghz, which is quite reliable. The chip can handle up to 1.375 without any problems.
Additionally, using auto-setting for initial OC is perfectly acceptable. Indeed, you're right—on auto mode, voltage spikes can occur briefly, often in the high 1.4s and even near 1.5, though this happens only occasionally. This behavior aligns with how the chip is built to manage its boost frequencies. It doesn’t maintain that voltage continuously. The reason we leave it on auto for startup is to guarantee a successful first boot.
To the OP, you can use coretemp to set your VID, which is essentially the maximum safe voltage for the chip.
I noted 1.3 as a common starting point for Ryzen 1.0 processors. If you manage to boot at 1.3v, test your temperatures—if they stay around 70°C or less, you can consider adjusting the clockspeed or lowering the vcore further.
But as both cats_Paw and I have emphasized, it’s important to understand these details. The guide I referenced is excellent for achieving a stable and repeatable OC.
Thanks in advance, I'll take a look but right now I only have the AMD Wraith cooler and will postpone overclocking until I get an aftermarket one.
Consider using a cooler with a downward orientation to ensure the airflow helps cool the VRM effectively. Ignore concerns about your case's airflow quality.
