Overclocking 2950X

[Sajeev]

Dear All,

   Greetings of the day. I need some help on overclocking my Threadripper 2950X. Hope to find the same here. Before I put out my doubts and observations here is my base system:

 

Motherboard: MSI X399 MEG CREATION (Bios Version:7B92v12 (latest version as per manufacturers website))

CPU: Threadripper 2950X

RAM: 64GB(8 X 8GB) DD4 2933 MHz Gskill TridentZ CL14

HDD: 2 * 1TB M.2 NVME SSD, 1 * 1TB SSD

GPU: 2 * RTX 2080 Ti FE (In NVLink Config)

Cooling: Custom Water Cooling, 2 Radiators (420MM + 280MM)

 

I believe I have a good & a powerful workstation with me. I would like to Overclock my processor and see how far can I push my system and get the maximum speed out of it as I think I have a good enough cooling system. Now I tried a tweak by going to the bios and adjusting the CPU Ratio to 42 from the default 35 and increasing the Core Voltage to 1.4125, now the system apparently works fine but as soon as I run Firestrike 3D TimeSpy benchmark initially I get a blank screen but may be after a couple of minutes the screen resumes normal. Now my questions are:

 

1. Am I doing something wrong here? 

2. Can I actually Overclock this system?

3. Is there something called Turbo Boost on this motherboard for this CPU and if yes then how do i activate it. I have seen videos of some people setting Base clock of 1950X (Not 2950X) to 4.1 and getting a Turbo Boost of 4.9.

 

I am new to Overclocking and still don't understand a lot about it and thus would request you guys to please help.

 

Cheers

Drop voltage to 1,35 and then ratio 4,2. Run a CPU stresstest and check if stable

 

What is your PSU?

Sorry forgot to mention about the PSU. I am using cooler master V1200 Platinum Standard 1200 Watt Power supply. You mean I should undervolt it?

Undervolt?

 

No, it will be an all core overclock at 4,2 ghz 1,35 volts.

Worked but with some more tweaks, however I still want to know if this will have some kind of turbo boost or if by OCing this CPU I kinda already reached it's turbo boost limit.

What were the afformentioned tweaks?

 

This way of overclocking is a locked multiplier and not a boost changer.

Had to change the CPU soc voltage and tried playing with the ex settings I had to have the most stable working environment. 

 

Any way to change the boost changer?

No experience with boost overclocking sadly. Only the more common allcore overclock.

What did you change the CPU voltage to? Because if its above 1,42 volts you will be straying into very bad territory.

I am currently at 1.4125. But would like to see some kind of turbo boost happening during benchmarks or something to 4.7-4.9 as I believe 1950X is doing it.

As i said, no experience with boot tweaking. 

 

From everything i know, Zen 1 and Zen + have a hard voltage curve beyond 4ghz and 4,2 ghz respectavly and i would take those high boostage numbers with lots of salt considering that to achieve tyat sort of clockspeed you would need a lot of voltage.

Got it, thanks man. I guess I will just be happy with 4.125 V offering 4.2GHz for now, unless I find something good and solid, I will share it here.

I've got a 2950x and a 1950x running back to back.  The 1950x does not boost to 4.9 ghz.  You're referencing a youtube video: "WicKed Threadripper Overclocking Guide to 4.1 Base 4.9 Boost!" 

Spoiler, he's not getting a 4.9 turbo boost.  Once of the commentators on this video point out it would take a 1.8 voltage at over 120 degrees C.  The bench-marking software he was using didn't record as well as it should have.  I don't mean to put down the creator here, because I really liked this video.  However, just as a PSA I wanted to update this.
