3900x Thermal Paste & OC

[ChaoticChaosx]

I was looking at videos for this. I didn't want to much (which I feel like I did) or not enough. I wouldn't worry about it with preapplied on my 360 AIO but I just replaced my intel with AMD Ryzen 3900x.

 

I know that the ryzen chips are different lay out wise, so instead of in the middle with a "pea" size I did two dots at top and bottom. Making it act as when I put the pump on it should spread out...right?

 

I just don't want to make it have more heat then it already has do to I will be overclocking it later tonight.

 

I used frostbite 2 thermal paste if that makes a difference it's seems like MX-4 as how wet it looked.

[Nick Neuburg]

just do a slightly larger than normal white rice size and you will be fine

[Statik]

Just use a pea/grain of rice, and don't spread it.

 

And please do your research into max safe voltages on Ryzen 3k before OCing.

I spread mine, but mine are lidless so I don't have a choice. Never had an air bubble on a core die that cause some sort of issue, so spreading the paste thinly is a sure fired way to be sure the plate is totally covered. As a result of such findings, I always spread the IHS plate. I can often times use less thermal interface material as a result.

Right I always take the voltage down cause auto is insane to begin with,

Would you recommend reapplying it before continuing or is this okay?

I don't mean this in a disrespectful way, but please take the time into reading into OCing Ryzen 3000 and finding the max safe voltage, or you WILL degrade your silicone.

 

 

You need to run P95 Small FTT's for an extended period of time and find what your vcore voltage tops out at. That's your max safe voltage. STOCK CLOCK SPEEDS DO NOT REFLECT MAX SAFE VOLTAGES ON RYZEN 3000. Turning down your stock voltage because it's "too high" is also a bad idea. Ryzen is designed to take high voltages (1.45v+) in low intensity workloads in order to help the CPU boost and give you the best performance possible. As soon as you load your CPU you'll notice your voltages drastically drop. You might hit 1.47V in chrome, but if you were to pin a 12-core 3900x at 1.47V  it would obliterate your chip and probably burn down your house.

 

Ontop of that, Ryzen is pretty much pinned out of the box, and there's very little headroom for OCing, and honestly, it's usually recommended to leave them stock wth PBO + AutoOC enabled. Especially if you're mostly gaming (or not pinning all cores), you can lose performance with an all core OC (though benchmarks won't necessarily reflect this).

 

So basically I wouldn't really recommend OCing Ryzen 3000, but if you do, you need to know exactly what you're doing, and know the max safe vcore voltage for your specific chip (every individual CPU is different), and on top of that you need to accept that this isn't a 14nm Intel CPU where you can just throw mad voltage at it and get it from 3.6 - 5.0Ghz easily.

 

Someone on reddit tested this theory and sacrificed 2 3600s and degraded the silicone to the point where his CPU was unstable in a couple months. At the end of the day it's your money and your gear, but I feel very few Ryzen 3k owners actually understand OCing their chips, and think OCing is what it was a few years ago, and it's not, and I'd hate to see you break a $700 CPU because of it.

I didn't think you did, if my reply sounded like that, I apologize.

 

Just meant as I always do research before any attempt of any type of tuning with PC hardware, I've done hours upon hours when I built my first system back in summer of 2017.

 

I won't reapply the thermal paste just yet then.

 

IStock set and running prime95 small FTT's.

 

I understand what you're saying. Not a noob or anything with overclocking intel. For this is my first ryzen CPU ever as it is time to upgrade from a quad core intel. I know how to tune the infinity fabric and core itself. About the voltage I didn't know about, that being a "bad idea" so thanks for that.

 

PBO & AutoOC I will enable after a two hour run of prime95 to see where my voltage max is.

 

However I do use my chip for rendering/encoding, live streaming, and gaming.

 

So everything is back to stock and running prime95 small FTT's. I really appreciate your knowledge drop. Haha. Very very helpful. Also yes, breaking my new chip would be the absolute worst thing imaginable. Thanks again.

Right on, sounds l like you're on the right track then. You didn't sound like a dick, I just didn't want to come across like I was insulting your intelligence is all.

 

Best of luck and let us know what numbers you get on that OC.

Ohh okay got you.

 

Also there are two different PBO is bios but I enabled the one in Ai tweaker as well as the "AutoOC".

You have the same motherboard as me so you know where I'm at if that is the wrong name in bios area.

 

Only thing I changed both stock and when PBO+AutoOC is memory set to 3200mhz D.O.C.P.(XMP)

 

Stock was around 36-40c idle during prime is was 62c-72c the next 3 bars were going red most of the test. Cores were 4.6Ghz voltage I'm not sure where to find it but on "AMD master" was reading 1.0879 during test fluctuating, must looking at something worng cause obviously not my max safe voltage. Where do you find this number in prime?

 

PBO+AutoOC is idle right now at 4850 on the cores voltage at 1.39288 I seen 1.4 for a couple second here and there. Temps idle are 41c pretty much constant.

 

I'll run prime on this later on tonight and edit this post.

 

EDIT: Current hour in prime95 with PBO+AutoOC so 3 hours in and never when above base clock as you can see here.

I mean everything is multi-core now so I don't know if I should not just do manual OC all core. You got me scared with ryzen attempts. Haha. Should I run a avx2 instruction with the Small FTT's you think?

Sorry I was working the past few days,

 

I use HWiNFO64 for all my tests. One thing you need to do is once you start P95, you need to "reset" the stats. If you don't then your "max" voltage and clocks will be super high because at idle your CPU was taking high voltage and boosting to it's max. Below is a screenshot of my screen and I'm running P95 Small FFTs with AVX enabled (I just leave everything "stock" and click small FFTs (not smallest ffts)).

 

The voltage you're looking for should be your vCore voltage (or in my case the CPU Core Voltage). I started P95, waited a few seconds and then "reset" HWiNFO. It's only been running for a few mins but my voltage appears to have leveled out and peaked at 1.25V. and running at a solid 4.0Ghz.

 

It's also worth noting if you just want to see what OC you can attain (i.e. Benchmarking OCs) you should be able to push it past this voltage, but i wouldn't recommend it on any sustained OC.

Not a problem I let mine run while I went to work today.

 

I usually use hardware monitor as well just heard some saying its reading are wrong with ryzen 3000 maybe that's been updated.

I

want attain (find) my max OC and run it like that so I can get the best performance I can. I'll return to stock reset an run it since I can read HWinfo better like I did with my intel. I believe an hour run is decently enough time or watch a movie while running it.

Will report back

on ryzen 3 just use PBO and you will get good results. unless you have a silicon winner OC on ryzen 3 is almost pointless unless its solely for the hobby.

 

I did a OC on mine to the max I could then I used PBO and its pretty much the same performance gain with no hassle of doing an OC and then stress testing for 5-25  hours to prove suitability.

Yes, but isn't PBO single core?

Also in my bios there are 2 PBO options one with "warning" message "accept or decline" and one in the Aitweaker which is the one I chose to enable with AutoOC.

 

It is a hobby of sorts, also fun for me to overclock and find my max. If PBO is not single core then yes I agree it would be much easier. SO thats what i did results.

Results PBO+AutoOC=4.0Ghz all cores
