Overclocking FX-8370

[ThatFellaNick]

Hey guys, so Im overclocking my 8370 I got it at 4.70 GHz Kinda just wondering if I may be doing any damage.

 

I used Prime95 to test stability.  I tested using blend. All cores passed 2 test. core 7 got Illegal Sumout on test 3 so I decided to stop.

 

 Core Temp and Corsair Link(Using H100i) claim my temperature is about 45C at max. Not sure how reliable it is. 

 

BIOS is 30C at idle

 

Here is the CPU info

Does everything look okay to you guys? You guys think im safe?

 

Thanks for taking a look

that's fine if you aren't on stock cooler.

45c 4.7ghz at 1.488v. I am finding this hard to believe.

[QueenDemetria]

1.488v is a little high for my liking.

Am3+ chips have much larger heatspreaders & dies, making them easier to cool, they also have lower TJmax's then intel chips and don't run very hot in general.

having lower TJmax has nothing to do with the heat, the  actual heatspreading being larger does help but I somehow doubt the it helps 1.488v with 45c on h100i. I have never in my life heard of that. ESPECIALLY in prime 95.

He used Blend, which from my experience, puts out much less heat the Small FFT, that could be the cause of the seemingly low temps.

 

@ThatFellaNick That looks like a nice overclock. Although try 4.8 Ghz. I can do 4.8 GHz perfectly stable with 1.5v on my FX-8320.

Thanks for all the replies First time overclocking. You guys are great

I started at 4.3 and slowly increased the multiplier along with voltage 4.5, 4.6, 4.7 

Was able to boot into windows all times.

When i got to 4.7 the test started failing on 3 cores or so within 5 minutes.

So i upped the voltage and tested. Every time it got more and more stable. 

Im probably at the stablest its been all day.

My only concern is if the temps are correct.

But when i was at stock it was pretty cool also.

 

I tested and this time i used Smart FFT

Here is a screen after about 5 minutes of stress testing:

 

Also its a bit strange that one of the readings on the mobo gets to 92C. Not sure whats going on there it idles around 73C Its always been kinda hot

 

But anyways what you guys think?

Try using HWMonitor instead. Also, what motherboard do you have?

The die is also much bigger, it makes a very big difference.  This is part of the reason everytime we shrink the die the temperatures go up.

The die size is 315mm 2 on an 8350, compared to 177mm 2

[ThatFellaNick]

Well I used HWMonitor here is a shot

 

Looks like its getting way too hot at 87C if im reading it correctly

Also i have a MSI 970 Gaming mobo. 

What you think I should do?

[lovingGamer]

45c 4.7ghz at 1.488v. I am finding this hard to believe.

me too

That sceenshot...a 4min run? How about you run that stuff for 20-30minutes and THEN post a screenshot.

Deceiving us doesn't help you at all.

I would love to do a 30 min test for you guys but im not sure what program is showing me the correct temp, I don't want to burn it up lol

MSI Command Center, Core Temp, and Open hardware monitor say the max is around 47C but on HWMonitor TMPIN1 says 87C but TMPIN2 says what the other programs say. Not sure what to go off of.

[fx63007850]

use ibt avx at very high for 20 runs, to monitor temps use coretemp as it will show you the speed, load, and if its at 100% load  

 

here a pic how i do it

TMPIN1 Is the VRM temperature.

 

Scroll down with hardware monitor and it should show another temp for the CPU.

 

Try using a MSI utility to display temp.

 

Most monitor systems are off.

 

4.7Ghz at 1.488 is ok, not exactly the best but it will vary from CPU to CPU.

 

Mine does 4.9Ghz at 1.472V in Prime95 and I never use blend.

Thank you so much, I literally just noticed that temp this morning.

1.488 seems to be the stablest one, but what do you think I should do with it?  

[ThatFellaNick]

So I clocked it up to 4.8GHz and used the same voltage settings, here are the results 

 

Idle:

 

100% Load:

 

Prime95 after a hour:

 

Kinda strange that the voltage is higher on idle and not on load, i hope it's not too high

Also strange that the max temp was 42C. Maybe because my room is cold.

 

So at this state do you wonderful people think im safe or will I have a small square paper weight in a few months?

Your idle voltage is extremely high.

 

You need to change your LLC(Load line calibration to Very high or extreme). This will increase voltage under load and should allow you to drop voltage under idle.

Ill try that now

[HEU7Hwhu7]

Do a little BUS OC to take some voltage off that CPU.

Thanks for taking a look

Corsair Link just says trash. 1.488 is BAD. I run my 4.7 ghz at 1.45...

[ThatFellaNick]

@Priller Turns out my motherboard lacks LLC settings

 

About 10 minutes after showing those results I had a good feeling that the voltage was way too high so I went back to stock again.

Its strange because yesterday I was at +0.150000 V  on the voltage setting and it was only 1.488v, I went back to the stock clock for the night and started again today with the same settings and it was at 1.560v

[sgloux3470]

Seems pretty high to me.

 

 

Here's my 8370 at 4.8 GHz.

 

 

 

Anyway prime95 errors usually indicate insufficient voltage.  Can you try 4.4 or 4.5 Ghz and see if you get the same issue?

 

Temp seem godly low too for that voltage.  I'm also running an h100i and at ~1.47+ I'm pushing high 50s to mid 60s.  At 1.56 V I reach thermal shutdown very quickly.  Are you using some sort of offset mode to overclock?  Or Auto?

The 8370 is binned to the max.
