FX-8350 | Are my Temps OK ?

NanoEx · Oct 2, 2014

I've just finished my build and started overclocking my new AMD FX-8350.
I'm Using a Corsair H100i with s tatic pressure optimized fans in push-pull.
After a few Test on 4.8 Ghz and less i finally went for my actual goal of 5.0 Ghz.
Since I got this frequency running stable i was wondering myself if my temperatures are alright.

Here are my specifications:

CPU: AMD FX-8350
Motherboard: Asus Sabertooth 990FX R2.0
RAM: Corsair Dominator Platinum 1866 Mhz PC3-15000U CL9-10-9-27
PSU: EVGA SuperNOVA 850 G2 850W ATX 2.3

I've been testing the CPU @ 5.0Ghz
FSB: 233 Mhz
Multiplier: 21.5
HT Link Frequency: 2560Mhz
Vcore: 1.488 V
Vnb: 1.181 V

C6, APM, Turbo, etc. are turned off.

RAM is currently running @ 1860 Mhz

My temps under full load:

Socket temp: maximum of 73°C (163°F)
Core temp: 59°C (138°F)

Are these temperatures okay ?

What are you using to test the CPU?
How long has it been running?
What software is reporting those temps?

7 Hours straight
Prime95
HWMonitor, Core Temp

ATMINSIDE · Oct 2, 2014

Prime95.... Blend? SmallFFTs? LargeFFTs?
What software is giving the temps?

NanoEx · Oct 2, 2014

Small FFTs, for programmes read above. I edited the post x)

ATMINSIDE · Oct 2, 2014

Run Blend, it stresses the overall system better.
I've found SmallFFTs testing isn't stable for my daily usage, but Blend is.

Go ahead and drop Core Temp, you just need HWMonitor

That's what i get out of it. Gues this means the System is unstable right ?

ATMINSIDE · Oct 2, 2014

Yeah, I'd back down to 4.9GHz and try again.

NanoEx · Oct 2, 2014

The last succeded Test were this:

Core 4816
BiosVcore: 1.400
RealVcore: 1.464
MaxTempSocket: 67°C
MaxTempCore: 53°C

I'll go ahead and try those...
Thanks for your advice

ATMINSIDE · Oct 2, 2014

Sounds like you know how to tweak it in, just keep testing settings till you find something you like

I keep the package under 62°C, socket under 72°C, and vCore under 1.5V.

As far as i can tell the Temps for Cores won't reach more then 42°C
and Socket are less then 55°C

Error isn't occuring yet.
Is this a usual Temp ? Cause im used to temperatures like 60-75°C
Everything was tested in "blend-mode".

FSB 200Mhz
Mulit: 24
Vcore up to 1.452 V

ATMINSIDE · Oct 2, 2014

Yeah, temps look normal.

Nano, seeing what is actually going on with the rig is useful when trying to help someone along. Posting screen shots of Hwmonitor under load and the following tabs in Cpu-Z, Cpu, Spd and Memory, lets us see whats going on under the hood a little better. It should look like this "thanks Rgone", when you post it. Additionally, if you add a signature to your post it is also helpful so we do not have to scroll back up to the first post every time to see what components you have. Please use the inforum tool to host the pictures, which can be done by "go advanced" and clicking on the paper clip icon.

NanoEx · Oct 2, 2014

This looks fine to me... Any Advices ? Should i go for 5 Ghz again ? (probably means Vcore would hit 1.5 V border.

NanoEx · Oct 2, 2014

Suddenly this happens...

ATMINSIDE · Oct 2, 2014

What were the temps when that happened?

At some point before you push further you should establish stability for at least 2 hours of prime blend. It will make it a lot easier to try and get it stable when you have a fall back stable OC.

caddi daddi · Oct 2, 2014

just a note or two.
your ram needs to be set in the bios to the xmp profile, your giving away some performance.

what have you done to replace the airflow to the socket area that was taken away by the cooler pump?, the socket temp looks real good.

it looks like you have a pretty good cpu, voltage induced in stability will not be seen till about 1.6 vcore, you will be temp limited.

You probably need to be looking at a custom-built water loop if you're serious about 5.0 ghz or better. The Corsair H100i is just tad better at cooling than the best air coolers.

Actually you were completetly right. Im heading forward to a custom Water Loop with some good parts from Ek WaterBlocks.

I'm not quite sure how i shall ajust the different parts.

Even tho it makes no noticable difference, could you please tell me if this would work ?
