Ryzen 3600 Voltage

TNA said:
Depends on your motherboard I suppose. But you will likely in the cpu section see something like 36x, you need to adjust that. Trouble is, if you can’t even find that, you should probably not be messing with it, or take it easy and go step by step so try 40, then 41 etc.

system is
AMD RYZEN 3600
Be Quiet! Dark Rock Pro 4 CPU Air Tower Cooler.
MOTHERBOARD...B450 TOMAHAWK MAX
GPU radeon rx 590 gaming 8gb
corsair lpx RAM.. DD4 2X8 16 GB 3200MHZ
psu corsair rm750x
would love to be able to overclock the 3600.
 
In my ASRock board there is no "multiplier" option there is a frequency option instead which you set the target frequency and it sets the multiplier accordingly, might be similar on the MSI boards.

There you go ;)

 
I’ve been having a play with the CPU multiplier and voltage. It’s really strange, mine won’t go to 4.4ghz without using close to 1.4v even then it’s not 100% stable. I’ve found if I back the multiplier out to 42.50 I can reduce the voltage all the way down to 1.175v which is perfectly stable. The voltage will more than likely go down more but that’s currently where I’m at.

4.4ghz @ 1.400v gives a CB20 score of 3896
4.25ghz @ 1.175v gives a CB20 score of 3831

Maybe one of the cores is weak which is holding you back, if this is the case you could try setting the stronger CCX to 4.4 and the weaker one to 4.25.

Based on that cinebench score alone - I can tell you right now your 4.4ghz overclock is Unstable.

It's a little trick I learned a while back - when you overclock but get the same or worse score compared to before, it means the overclock is Unstable.

Even though the overclock makes the CPU run faster, it's encountering calculation errors and that brings the score down - eventually it will encounter a calculation error that it cannot fix and then you get a BSOD crash.

Yep. 4.4GHz should be around 4000 points.

thank you TNA,


will have a play and let you know

No problem. Just be careful, don’t bork your pc and blame me :p

Go 1.275v and then up multiplier by 1 notch, test for stability using cinebench, if no crash go up by 1 again. For a final stability test, run blender and handbrake to be sure you are rock solid stable. Oh and play games. If unstable back down by 1 multiplier and test again.

you are not to blame for anything i do on my pc, martin

well that worked a treat thanks.

No problem. I would however say, keep it below 1.3v for 24/7 usage. I would not use more than 1.3v myself personally based on what I read. May shorten the life of your cpu potentially. But maybe not.

0nly use pc for 10am to 11pm so should be ok?
 
I'm rocking 3.375Ghz @ 1.35v. I've put hours upon hours into testing and this is the best tweaked stable result.

Even with the options hard set in the BIOS. Ryzen Master reports all the normal down clocking / core sleeping with much reduced voltage, which make me a bit happier :)
