Long term stable overclock settings for Ryzen 3600
Long term stable overclock settings for Ryzen 3600
A few days back I upgraded to a Ryzen 3600 and the results were impressive (it came from a 1500x). But the weather has been really hot – the temperature is around 32°C, though it feels like 35°C. With stock PBO, the processor runs between 4 to 4.2ghz, but the temperatures aren’t great; it climbs straight up to 76°C and then gradually reaches 81-84°C.
I began testing a fixed OC and was able to reach 4.2ghz at 1.2v (about 1.18 underclock due to VDD drop). When I start Cinebech, the temps begin around 60°C and slowly increase to about 71°C.
Recently, I read in an Overclock forum that a fixed OC might damage a Ryzen 3000, so it’s better to stick with stock performance for the long term, even if it means slightly lower speeds.
Here are my specs:
- Asrock B450 HDV R4.0 (expect poor OC potential, 4 phases, no heatsink, so I added an 80mm fan)
- 16GB Corsair Vengeance 3200 Cl16 (with Ryzen safe optimized timings)
- Ryzen R5 3600 with Arctic Freezer 33 eSports edition
- MSI GTX 1650Super Ventus XS OC
- Non-certified Cooler Master 550w (planning upgrade soon)
- Case with 120mm intake fan @1200rpm and 2x 80mm exhaust fans @1600rpm.
So... I’m satisfied with the temperatures, and both single and multi-score performance are excellent. PPT, TDC, and EDC are all under 100% at full load. My main concern now is whether this manual OC will harm the chip over time.
Your values should be acceptable, but early discussions often assumed 1.3v was safe regardless of circumstances. Unfortunately, some individuals discovered the reality was different. With the Ryzen 3000 series, each processor has its own safe operating voltage. To determine yours, follow these steps:
Disable manual overclocking and set PBO to maximum. Ensure LLC is enabled automatically.
Close all monitoring tools except HWiNFO64.
Scroll down to CPU Core Voltage SVI2 TFN – this shows the actual voltage applied (not Core VID).
Run Prime95 or OCCT and perform a basic FFT analysis across all cores.
Don't take everything at face value. Your own setup works better than the automatic one, offering more stable voltage and temperature than what most BIOS settings provide.
Your preferences should be acceptable, but the topics discussed earlier relate to initial assumptions about 1.3v being safe regardless of conditions. Unfortunately, a few individuals discovered the reality was different.
With the Ryzen 3000 series, each processor has its own safe operating voltage. To determine your safe limit:
Turn off manual overclocking and set PBO to maximum. Ensure LLC is enabled automatically.
Close all monitoring tools except HWiNFO64.
Scroll down to CPU Core Voltage SVI2 TFN – this shows the actual voltage being applied, not the one requested by Core VID.
Run Prime95 or OCCT and perform a basic FFT analysis on all cores.
Observe the SVI2 voltage; it will fluctuate slightly before stabilizing, which indicates your safe operating voltage.
Keep in mind that this value varies per CPU model. Some users report up to 1.3V, while others mention as low as 1.2V.
Avoid exceeding your FIT voltage. For maximum safety, stay below it. Also remember that temperature matters – even if the voltage is within limits, sustained high temperatures (like 80°C+) can cause damage over time.
For newer CPUs, you may achieve stable results at lower voltages. Earlier models had poorer performance, but recent releases have improved significantly.
Thank you for your response. I bought this chip in "preorder" on Amazon last month, so it seems it's a recent model. My SV12 stabilized around 1.35v after six minutes, though it occasionally fluctuated between 1.3 and 1.38. Here is a screenshot:
Everything was normal except for the XMP profile. Also, I don't like the power reporting deviation feeling quite high.
No problem at all, it seems that you have a very nice CPU.
That means that your OC is perfectly safe, if you find a way to get your temperatures under control a bit, you can even bring up your voltage to see if you can hit 4.3 (or even 4.4) all-core.
If you do get the heat controlled, I'd still recommend that you do not go over 1.28v just to be safe.
(That's what I'd do if I had your CPU, and I won't advise things to people that I'd not do myself).
For reference, I've got a 3700x that has a fit of 1.25v
I run 4.2 all core at 1.218v (purely for temperature reasons, it's much more chilled this way and I don't notice any performance drops).
If you want to squeeze our more performance, try and tighten your RAM timings a bit.
You said that you have the Corsair Vengence, (you may have the same as I do), if that's the case then tighten your timings to CL14.
I hit 14-17-17-17-34 at 1.4v and I've not had the time to really see what else I can do (work takes up all my time), but I do have a feeling that 3600CL16 should be possible.
The one caveat to that is that the Corsair Vengence 8gb sticks come in 2 dies, Samsung C-die and a low-grade B-die.
If you have the B-die variant, then 1.4v is perfectly fine, but if you have the C-die, do you exceed 1.35v. I've even heard that lowering the voltage on C-die sometimes helps stability for the OCs.
Unfortunately, the only real way to check what you have is by opening your case and looking on the RAM stick itself. What you're looking for is a version number (an amazing thing that corsair does to make identifying easier). If your 16Gb is 2x8gb sticks (I hope that it is) then the version numbers mean:
4.31: B-die
4.32: C-die
If you have something else, then the full list is
here.
Note that this is important as sometimes thaiphoon burner gets lost between c-die and b-die.
(If you have b-die, don't jump too high just yet, officially this is 'down binned' b-die' and that means that it is sometimes not the good stuff that gets people hyped about - you'll just have to test what you have.)
If you have c-die, then
this place
will be of great help to you.
Another way to get more performance is with FCLK overclocking.
If you cannot get 3600 on your RAM then see if you can increase your FCLK to 1900.
Generally speaking, you want FCLK and RAM speeds to be 1:1 (so 3200:1600) as having it otherwise will force a latency penalty. However, the exception to that rule is if you can get your FCLK to be over 200mhz faster than your RAM speeds.
A note on FCLK
First, not all processors will hit 1900, bad ones will be stuck at 1700, most go to 1800, the better ones go to 1900. This is because you're playing the silicon lottery all over again, this time with your IO die.
That means that you can have an excellent all core OC, but since the IO die is a different chip entirely, that needs to be good as well.
My 3600 pulls 120w in the same situation, so I believe your board is underreporting PPT. 1.25-1.275v should be a very safe OC voltage; you’ll easily reach 4.3ghz or higher with that. I’d definitely aim for the memory to hit 3600mhz like the other poster mentioned.
THANK YOU FOR ALL THE DETAILS, according to Thaiphoon Burner, my DRAM is a Hynix A-die, but I believe I’ll keep it at 4.2ghz with a 1.2v setting for now. My motherboard isn’t ideal for overclocking, and the PSU appears to be nearing its limits, getting quite hot, so I won’t risk anything further. I truly appreciate the information—it will definitely assist me once I upgrade my case and PSU (one that meets at least 80+ bronze standards).
My monitor runs at 75Hz, and my graphics card is a GTX1650S, which means the CPU performance is currently sufficient for the rest of my setup.
