Overclocking Ryzen

[Armakar]

I'm overclocking my friends Ryzen system, and we're trying to get it to 4.0GHZ. It boots at 4GHZ at 1.35 volts, but crashes within 5 seconds of running Cinnibench. He has a Captain 240 EX watercooler - is it safe for daily usage to bump the voltage?

 

Also, we're OCing his Memory, does Ryzen work with 3200MHZ memory yet?

what does it boot at with 1.35v? can it boot and stress at 3.9 or 3.8?

You can go up to 1.45V and be safe with Ryzen. Though do not exceed this for daily use.

 

Try again at 1.41 and enable load line calibration to combat V droop under load

It can handle 3.9 at 1.3 Volts.

Are you sure? I thouht AMD said don't go past 1.35 for daily use.

is that just booting or full system stress test. if it passes a full stress, try adding a bit more voltage like 1.38 or 1.4 and try again at 4.0. watch temps and do a stress test.

Stress test it runs cinnibench fine at 3 volts, 3.9ghz

then do as I said and try 1.38 then 1.4 at 4.0Ghz. as long as temps are not getting too high you should be fine.

Then stick with that if it is stable.

If you need more than 1.35V for 4.0 and only 1.3V for 3.9 GHz, then you are going to get next to no performance increase and just increase heat and power draw pushing any further. If you don't care about power efficiency though, then try 1.41V, if it is stable gradually drop it down and retest until you find the limits of the CPU.

As long as you keep the CPU below 80°C, it should be fine for at least 3-7 years under 24/7 workload.

I'll try that, but we tried overclocking his memory to 3200 and now the PC won't boot fullstop. He has a JBAT1 to jump the motherboard - but I guess the mothjerboard didn't come with a jumper cap so he can't use it. What should we do??

you can jump it with anything metal, a knife, screw drive just be careful.

 

I know ram is harder to do, most people get 2933 or 3000.

Just remove the battery to clear the CMOS (with system unplugged), or use a screwdriver or other metal object to short the jumper.

Not all boards are stable yet at 3200, and may require a BIOS update. There have also been reports that some people have got 3200 MHz to work with some processors and not others, so there may be limits with silicon lottery on the IMC.

Try 2933, or if the RAM is dual rank try 2666 or you might be stuck with it stock.

I think the official number from amd is 1.425 volts so you're still good.

[Simon771]

1,417V should be still okay.

But if you can run stable 3,9GHz on 1,3V ... I would stick with that.

Additional voltage and heat isn't worth that extra 100MHz.
