Question Questions about Ryzen 7 2700x Overclocking and Voltage (can't reach 4.2 with *Safe Voltages*)

[scrubs2708]

I just got my Ryzen 7 2700x and I have been trying to overlock it. (New to CPU OC)

I see that everyone is able to get 4.2 and 4.3 GHz under 1.45 volts/Auto Voltage
but when I try it just crashes.
iu even tried 4.2GHz on 1.5V I knew that it was a bit high. but it didn't want to complete a Cinebench 15 Run.
I was wondering why I can't get my CPU over 4.15Ghz at 1.48 Volts which is still pretty high.
if I try using Auto voltage it just soft locks after 1 second in any stress test.
Right now as of speaking my CPU is Running at 4.15Ghz at 1.48 Volts (Average Idle Temp: 45c) (Under load Recording and Gaming / Stress Tests Temp: 78c-85c )

Specs:

[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 is maxing temp?
What is maxing Voltage?
Does my motherboard supply my CPU with the amount I put in?
Will I destroy my CPU running 1.5 or under over time?
does it have anything to do with my Memory being Overclocked to 3266Mhz?


I know that R7 2700x prefers lower temps then high performance so I was wondering what temps R7 starts to drop voltage and Clock Ratio to get better Temps

It seems like I am the only one how cant find a stable Clock on 4.2 - 4.3Ghz But what do I know.
I am better at GPU overclocking then CPU O_0

Thanks for Reading <3

UPDATE: It been a while since I asked this question, but I would just like to say Thanks to everyone who have to gave suggestions!
The Problem was my Case, The 'corsair spec omega RGB'. the front does not give enough air for my '360mm AIO'. Luckily I was able to remove the Glass in front by unscrewing a few screws.
The thing is, I used auto voltage and because my AIO didn't get the air it needed, it ended up going way too high in temperature, resulting in auto voltage not giving my CPU more voltage.
After I unscrew the front-glass panel, I was able to get 42,25GHz, I was also able to reach 42,75 but unfortunately, windows crashed after 2 hours, same with 42,50.
I do think the reason I am not able to reach 43,00Ghz (With 1.51V) was that I didn't get a Fantastic Silicon lottery, or maybe because I needed to give it a bit more voltage? Idk.
I really don't want to give it: more than 1.51V, it's quite high already.

- Anyway, Thanks again for your help!.

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.

To answer your questions a negative offset reduces the voltage going to your CPU by whatever the offset is. Basically on AUTO setting PBO will automatically adjust the voltage going to your CPU, unfortunately every case that I have seen it supplies too much power, or at least way more than what is actually needed. Say your processor can hit 4.2Ghz using only 1.35V but on AUTO it is supplying 1.55V to the processor to hit the same speed- both settings will work, but your going to be seeing much higher heat generated at 1.55V which will limit your overclock boost headroom. So a negative offset will lower the 1.55V to 1.36V and be much closer to the minimal you actually need.

2. I tried to explain this but may have been obscure. Our motherboards have no scalar setting that you can enter under PBO settings. That is why I had you set performance mode to Level 2. At level 2 the scalar is automatically set to 10X, which is what you want.

I also noticed with your supplied pictures that you are massively over volting your CPU. You have the offset mode set to positive "+" sign. You need to have the offset set to negative "-" sigh. And start with a negative offset of 1.000V then work your way to higher negative offsets via trial and error to see how high you can push the negative offset (which because it is subtracting voltage will actually be giving you lower Vcore).

I would also recommend that until you get your system stable to just run your RAM at "stock" which is achieved by simply setting the AI Overclock Tuner to D.O.C.P. mode.

Right now I would say that your biggest problem is that you have set a positive offset by accident. What this is actually doing is providing extra voltage to the AUTO voltage scaling that is already too high to begin with. With that positive offset it is possible that you are hitting over 1.6V and that much voltage can damage your processor very easily, I suggest you correct that situation ASAP.

i cannot set my CPU V on offset mode any higher then 0.5000V 1.000V is not possible

i cannot set my CPU V on offset mode any higher then 0.5000V 1.000V is not possible

Just to be clear the Vcore (cpu voltage) on the ROG Strix X470-F motherboard is called VDDCR CPU Voltage. That you select Offset Mode. Then right under that you'll see VDDCR CPU Offset Mode Sign, that you set to negative "-". Directly under that you'll see VDDCR CPU Offset Voltage that you can set to 0.1000 to begin with and then through testing see how high you can take it. This will apply a negative offset so it will remove voltage from the processor, the higher the number the less voltage is supplied to the CPU. I was able to get my processor stable at a negative offset of 0.11875 which will keep my processor at 1.36V even when running Prime 95 torture testing. Every processor is different so you may find you need more or less voltage than mine. In my previous post I put the decimal point in the wrong spot, I will be updating it. A negative offset of 1.000V will definitely not work, I meant to say start with 0.1000V.

MB: ROG Strix X470-f Gaming
RAM: 32 GB Hyperx Predator DDR4 3200MHz (4 x 8)
GPU: NVidia GeForce RTX 2060 (6gb mem)
PSU: Corsair TX 850M (850W 80 plus Gold)
CPU: Ryzen 7 2700X and stock Prism Wraith cooler

So when on PBO I get phenomenal Speeds but Core V shows in Ryzen Master as 1.45 to 1.55...for short time I viewed before shutting system down. Temps were still under spec but were up there 75 to 84c and EDC (CPU) was like 1000% if I remember correctly and RED.

So I shutdown right away and started reading up on what I should do...I would like but don't always need that level of performance..and I am a noob at this whole OC thing...and read that i shouldn't even try...but if I turn everything off. I get stock 3.7...and would rather better than that.

So I was hoping someone could give me a method to get to a stable setting with PBO and let Ryzen do its thing..without burning down the house..lol

Any guidance would be greatly appreciated.

Cheers,
Mike

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.

Actually, ALL consumer dual channel motherboards should ONLY be populated in the A2 and B2 (DDR4_1(Or DDR3_1) or DDR4_2 (DDR3_2) for some boards) slots which are always the second and fourth DIMM slots over from the CPU socket. That is for EVERY dual channel consumer motherboard I have encountered for as long as modern high density chips have been in use, and likely prior to that as well although I have not bothered to verify that since I rarely see those platforms anymore so why bother. Every. One.

Using the A1 and B1 slots CAN work, sometimes, on SOME boards, but I've seen a awful LOT of systems where populating the memory in those slots caused a variety of problems including lack of dual channel, wrong speeds, failure to POST, XMP settings won't hold in the BIOS, and on and on.

Just wanted to clarify that so it was not mistakenly understood that putting them in either of those population scenarios was acceptable, because it's actually not, not in every case, and it's NEVER recommended for two stick population by any of the manufacturers that you use the A1 and B1 slots alone.

Start you own thread and you'll get tons of help. You are unlikely to get any at all by looking for it in somebody else's thread.

Did just that...thank you.

 

[thepixie]

Not sure what speed you are running your memory at now, but have you looked at the CPU Package Power when you up the memory speed? Made a big difference to temps and O.C. I could reach. Found clocking down the memory made a fair difference.

By the sounds of it though you have probably already tried lower memory speeds and hitting your CPU's max clock right?

 

[Darkbreeze]

The idea on Ryzen is to get good boost or OC performance AND have higher memory clocks. Downclocking the memory speed is counterproductive except as a last resort for basic compatibility issues. You certainly wouldn't want to lower the clock speeds on your memory below the profile speed just to try and gain a higher CPU overclock unless it was a significant bump in peak clock speed on the CPU.

On Ryzen, that's unlikely, since there is very little overhead for overclocking to begin with.

 

[thepixie]

Yup - that's why I suggested it, I'm not saying that it's a brilliant outcome

last resort for basic compatibility issues.

UPDATE: It been a while since I asked this question, but I would just like to say Thanks to everyone who have to gave suggestions!
The Problem was my Case, The 'corsair spec omega RGB'. the front does not give enough air for my '360mm AIO'. Luckily I was able to remove the Glass in front by unscrewing a few screws.
The thing is, I used auto voltage and because my AIO didn't get the air it needed, it ended up going way too high in temperature, resulting in auto voltage not giving my CPU more voltage.
After I unscrew the front-glass panel, I was able to get 42,25GHz, I was also able to reach 42,75 but unfortunately, windows crashed after 2 hours, same with 42,50.
I do think the reason I am not able to reach 43,00Ghz (With 1.51V) was that I didn't get a Fantastic Silicon lottery, or maybe because I needed to give it a bit more voltage? Idk.
I really don't want to give it: more than 1.51V, it's quite high already.

- Anyway, Thanks again for your help!.

All-core safe voltage is 1.375v, singlecore is 1.45v.
