s about overclocking and voltage settings for Ryzen 7 2700x, especially regarding achieving 4.2 with safe voltages
I've just acquired my Ryzen 7 2700x and have been attempting to push its limits. (Just starting with CPU optimization)
I notice that others manage to hit 4.2 and 4.3 GHz at around 1.45 volts/Auto Voltage, but when I attempt it, the system crashes. Even when I set it to 4.2GHz at 1.5V, I realized it was pushing too high. I expected a bit more power, but it refused to finish a Cinebench 15 run.
I'm curious why I can't push my CPU beyond 4.15Ghz at 1.48 volts, which is still quite high. When using Auto Voltage, it just locks softly after about one second during any stress test.
Currently, my CPU is running at 4.15Ghz with 1.48 volts (average idle temp: 45°C). This is under load, recording, and gaming/stress tests. Temperature range: 78°C-85°C.
Details:
[PSU] Corsair RM850x, 850W
[RAM] Corsair Vengeance RGB PRO DDR4 16GB
[PCB] Asus ROG Strix X470-F Gaming
[GPU] RTX 2070 Msi Gaming Z
[CPU] AMD Ryzen 7 2700x
What are the max temperatures?
What voltage limits can I set?
Does my motherboard provide enough power for the CPU I'm using?
Could prolonged operation at 1.5V or lower damage my CPU over time?
Is there a connection between my RAM being overclocked to 3266Mhz and these issues?
I understand that the R7 2700x is better suited for lower temperatures, so I was wondering what temperature it begins to drop voltage and clock ratio to achieve higher performance.
It appears I'm the only one struggling to find a stable clock at 4.2–4.3Ghz. What do others think?
I’m more experienced with GPU overclocking than CPU tuning.
Thanks for reading!
Do you have the latest BIOS version applied?
Is your memory setup consistent? Have you verified the memory configuration with Memtest86, initially at the standard settings and then with XMP activated? If not, this could be impacting your overclock performance. Should you have turned XMP on, ensure it is disabled until you’ve completed configuring and confirming the stability of your CPU overclock. Only after that should you proceed to adjust memory settings beyond the default SPD parameters, such as DOCP or XMP.

What frequencies are you seeing when everything is set to auto with PBO turned on? With a Ryzen, the maximum overclock on all cores is almost the same as the max boost on just a few cores. You didn't mention the cooler you're using, so I'm assuming it's the standard one. It won't allow more overclocking across all cores, so you'll need something more powerful.
CountMike is asking about the frequencies you receive when using auto with PBO enabled. He mentions that with a Ryzen, the maximum OC across all cores is similar to the max boost on some cores. He doesn't specify the cooler model, assuming it's the standard one and suggesting a better option would help. He notes that with PBO enabled, he reached 4.17 GHz using auto voltages but found it unstable, requiring manual static voltage settings. He also shares links to a Corsair Hydro H150i PRO RGB CPU and a compatible AI cooler.

Is your memory setup consistent? Have you checked the memory configuration using Memtest86, initially with the standard settings and then with XMP activated? Because not doing so could be impacting your overclocking. If you've enabled XMP, make sure to turn it off until you're ready to configure and verify the stability of your CPU overclock. Only after that should you proceed to adjust the memory settings beyond the default SPD options, or in other words, set DOCP/A-XMP, etc.

I possess the most recent BIOS.
I haven't run a memory test with MemTest86 yet, but I did use Prime95 (I'm unsure if that's effective) for one hour before shutting it down.
I evaluated both RAM models at 2133 and 3266 and they produced identical results.
I plan to perform the overclock without any dedicated Memory OC.
Temperature and power supply are fine, leaving "Silicone lottery" as the outcome.
You should be getting better results than that. First off, as someone else suggested, manual overclocking on the R7 2700X is all but pointless unless you are under extreme custom loop type cooling and are going for 4.4Ghz+. In most cases as long as you have the settings right XFR2, PB2, and PBO will be all you need to get 4.2Ghz (or better) all core boosts and 4.35Ghz+ single core boosts. I have just about the same setup that you do (only difference is different RAM brand). My all core boosts are 4.166Mhz - 4.215Mhz and single core boosts are always pegged at 4.35Ghz. I am also still on the stock Prism cooler.
You want to make sure a few things are set up right for performance. First off (after seeing the Verge try to build a PC- epic fail...) I now always ask people if they are running their RAM in dual channel and have the RAM in the proper slots (either 1,3 or 2,4 for their motherboard configuration) saying I have the same motherboard you do the RAM is supposed to be B2 and A2 (or from left to right slots 2 and 4). RAM has to be set in this fashion to properly run in the fastest dual channel mode possible. Next are you running the latest bios (Version 4207) from the Asus webpage? If not, flash the latest bios. With these boards after flashing I highly recommend doing a battery pull CMOS reset. Simply pull the battery on your motherboard for a couple minutes, push the power button a couple times with battery removed to fully discharge the PSU capacitors and then reinstall the battery. Then allow the system to fully boot into Windows, then restart and manually re-enter all your bios custom changes (don't just choose a profile as for some reason with this board it causes issues).
Next did you set the proper timings for your RAM in bios? The easiest way on our motherboards is just to set the AI overclock to D.O.C.P. mode (I recommend staying away from Manual mode and manual overclocking with Ryzen Plus). D.O.C.P. mode will automatically set the "approved RAM timings and speed" for you particular RAM. I recommend setting the performance enhancer option in bios to Level 2 as 2 will increase voltage allowances for better performance and set the PBO scalar to 10X (something that we can't manually set with this motherboard). Note there is the "overclocking" options of 3 and 4 but for best stability I recommend Level 2. Important note, with this motherboard I do not recommend touching APU frequency as it typically destabilizes the system and isn't a true bclk overclock turner. Next set the Performance Bias to Cinebench R15 as I have found it helps in much more than just Cinebench.
Next up is AUTO settings, which to leave on and which to set to manual or enable. I've spent a long time tweaking the bios settings for this board and have found that Vcore should be set to negative offset (as under auto way too much power is supplied to the processor) I found with my board I can run stable with a negative offset of .11875, but you may want to start with a negative offset of .1000 till you find the "sweet spot" for your processor. I also found that you want to set the SOC voltage to manual as again on AUTO way too much power is supplied, I have mine set to 1.06250V but it is recommended to set it at 1.1V and through testing lower the voltage till you find the "sweet spot". Next I recommend setting the C-state to enabled from AUTO as I was having major issues with the C-state on AUTO (was actually causing my CPU fan to stop responding and other random issues). I also recommend in bios setting an "aggressive" fan curve for whatever cooling you are using. The cooler you can keep your CPU and all other components the higher your CPU will boost, I have stock cooling on the processor but I have 6 140mm case fans (and am planning an upgrade to AIO soon).
Last up is to enable Precision Boost Overdrive. Make sure its actually enabled, you will have to accept a disclaimer and make sure you change the setting from AUTO to ENABLE. Everything else you should be able to keep on AUTO. You can of course also optimize your RAM by increasing the speed, and tightening the timings using the Ryzen RAM calculator. I have Trident Z RGB 3200Mhz RAM that I am running at 3600Mhz, but everyone's results vary with RAM overclocking and timings. Utilizing these settings Your 2700X should be able to boost from 4.166Mhz to 4.2Ghz all core and should hit 4.3Ghz single core as long as your cooling is adequate.

Ok... I do have my memory in dual channel Slot 2 and 4 witch it said in the manual is the right slots.
I also have the latest bios *4207*
Alltho my ram is running at 3266 and not 3200 which is the speed labeled on the website and the box.
I have also Enabled performance enhancer option to level 2.
I also went to Performance Bias and enabled Cinebench R15
Question 1: What does negative offset do? how does it work? and why those numbers (or should I just search it up?)
Question 2: I did find PBO but I didn't find anything called PBO scalar (There was only one option.*AMD CBS > NBIO Common Options > and then I had to accept a thing > Precision Boost Overdrive from Auto to Enabled*)
(Not that I don't trust you, I just want to learn this. so I would appreciate if you would tell me why those settings <3)
BTW: The reason I want higher speeds is because I am planning on recording/streaming and Video Editing.
so i would prefer a stabled clock then balls to the walls clock.
