Overclocking and Overvolting Questions

[naozdnelam]

So recently, I’ve been wanting to overclock my system. And I did it for the first time yesterday using AMD Overdrive Turbo Core.


Now I know there’s tons of the same topic that revolve around this, but I believe everyone’s is truly different as everyone has different hardware.


Now as for my system, it’s a prebuilt, so it’s quite stock, the only thing I’ve upgraded is the Graphics Card as I’m building my own computer this Friday.


Now, yesterday I used AMD Overdrive for the first time, and I used Turbo Core to reach 4.1 GHZ with my AMD FX-6300. After that I wanted to try and get it up to 4.2 GHZ, however my system crashed right after doing that.


Basically I have a few questions, do I need to up my voltage in order to get more GHZ, and is upping the voltage dangerous? I just would really like to achieve higher GHZ.


That’s pretty much all I’m wondering on.

Alright, thank you. And is my motherboard safe to handle such with a stock cooler? Keep in mind I’ll be getting a new cooler this Friday when I build my new computer.

Safe up to a point but you are going to start with small jumps and monitor everything closely, right ?

 

[naozdnelam]

Yes, for the most part. I’m mainly doing it to reduce bottlenecking in-game, and just to increase the overall enjoyment.

 

[naozdnelam]

Also, what is the safe voltage for my motherboard? As I don’t want to ruin anything.

 

[naozdnelam]

Anyone?

1.36v on any 760g board max.

That msi board is very low end & has a very low quality vrm setup.

If you've already hit 4.1ghz & its stable I honestly wouldn't entertain going any higher

 

[naozdnelam]

Alright, well I appreciate the answer. Also, I’m running TurboCore at 4.1 GHZ, so it’s not a full on overclock.

 

[madmatt30]

The fx6300 already has a 4.1GHz turbo setting.
You're not actually over clocking anything at the minute.

I did a big post on overclocking the 6300 on a cheap board ages back (which I never bookmarked & now cant find as I have a huge post count)

Deopping in bios , disabling turbocore , & setting a straight 19x multiplier for 3.8ghz gives ypu a bigger performance gain than any setting with turbocore still enabled

Turbo core forces big clock & voltage fluctuations unser load , to hit 4.1 it drops clocks on other cores to 3200mhz to stay within tdp requirements.

 

[naozdnelam]

Alright, thanks for the answer. I’ll stick to the recommended voltage limit when I actually do overclock.

 

[naozdnelam]

Also, I know I’ve said it before. But which is better for me to use. AMD Overdrive, or just doing it manually through my settings?


I believe I’ve researched it enough, but am still nervous about overclocking.

 

[madmatt30]

Bios always.

n0ns3ns3 above has hinted that overclockimg small amounts doeant give you much gain.

Im going to totally discount that theory & point you to this thread , half way day Ive ahown a twst on my own system with a stock 6300 (with its turbocore function enabled) vs a straight 3.8ghz full load clockspeed on all cores.

On multithreaded performance there is a close to 30% performance gain when fully loaded.

The how & why (because many would say the 6300 already has a 4.1ghz turbo speed) is because turbo speeds are dependant on cpu load.

You mever mentioned your cooler etc , 3.8ghz is absolutely possible on just about any board, with the stock cooler , with less than stock voltage.

 

[naozdnelam]

Yes I do have the stock cooler, part of the reason I was wondering the max frequency I could go.

 

[madmatt30]

You could with almost 100% certainty drop into bios.

1. Diaable the turbocore function
2. Change the multiplier to 19x for 3800mhz

Leave voltage alone for the time being.

Should run off the bat at that with very little temp or power increase.

In all honesty that'll be about the limit on that board especially with a stock cooler.

Absolutely worth doing though compared to stock settings.

 

[naozdnelam]

Alright, I’ll try that. Thanks for the response!

 

[naozdnelam]

But you said I shouldn’t touch the voltage, right?

 

[madmatt30]

No , leave the voltage on auto.

You already have amd overdrive inatalled ??

Download

Intel burn test
http://m.majorgeeks.com/files/details/intelburntest.html

Extract it to desktop or somewhere - it doesn't need to be installed

Cpu-z
https://www.cpuid.com/softwares/cpu-z.html

Install this one

Open amd over drive - opwn the cpu status tab so the core loads & thermal margins are on screen.

Open cpu-z , leave it on the cpu tab.

Open Intel burn test

Position the 3 windows so you can see them all on screen.

Start an intel burn test (it can be stopped at any time should the results look worrying)

You are looking for

1. Solid stable clocks at 3800mhz (likely 3799) on all 6 cores
2. 100% load on all cores
3. Thermal margins around 10c or more on all cores

Also take a note of the cpu voltage shown in cpu-z
BEFORE & DURING the intel burn stress test.

These 2 readings will be different , load voltage will be considerably more.
This is to ascertain firstly if there is excessive vdroop on the board
& also

1. If there is any headroom for higher clocks
Or
2. If there is a possibility of undervolting for better temps

 

[naozdnelam]

Alright I’ll try this, and the clock speeds should be stable at 3.8 GHZ, yes?

 

[naozdnelam]

Just a quick update, I’ve reached 3.9 GHZ stable so far.

 

[naozdnelam]

Another update, I reached 4.1 GHZ stable, however after about 15 minutes of playing PUBG I BSOD’d. Which I can only assume would be due to overheating.
