FX 8320 Temperature

[Aontaigh]

I have a FX 8320 and a Notcua NH-D14. Yesterday, the maximum temperature recorded throughout the days was 58 degrees Celsius. This was when playing Counterstrike GO for almost two hours. I have my FX 8320 at 4.5GHz and 1.45V. Since I booted my computer about an hour ago for general use (Internet, Skype, etc.) the maximum temperature has been 34 degrees Celsius. Are these temperatures fine?

[ALXAndy]

Yes. The maximum temp of a 83xx varies,but usually it's between 62c and 70c,

 

Let's put it like this - if your PC hasn't crashed or locked up then your temps are fine. My 8320 can do 73c before it locks up the rig, so I can get 4.93ghz out of mine completely bench and stress stable with a max temp of 72c.

 

Edit. Try lowering the voltage. I can get 4.7ghz stable on 1.42v

I'm using the lowest stable voltage, if I lower it any less cores start to fail during stress testing. I may try to lower my NB and HT speeds (2600MHz) to see if I can get the voltages down.

How have you clocked it? all multi? 

 

Some advice - start with the FSB. FSB clocking requires much lower voltage to get you to a high clock. I run mine @ 230mhz with a 20.5 multi. For 4.9 I go higher on the FSB as multi needs a shit tonne more voltage.

 

I can get mine to 5.29ghz on a suicide run with 1.5v.

These FX chips melt everything when stressing all the cores at the same time. General use however(browsing, watching 1080p videos, even not so CPU bound gaming) gives a a very good heat output.

My temps never exceed 8-10 degreeds C over ambient temp (I consider the SSD temp the ambient temp) when doing normal computing. Stressing all the cores however (IBT), gives me 55 degreds cpu temp, about 61 degreeds socket temp when having about 28 degreeds on the SSD all this @1.18V wich sometimes spikes to 1.218v on the vcore with a cooler wich is tad better than stock one.

EDIT: My advice for you is to use OCCT for stressing. It detects errors very fast and the temps are a lot lower.

Yup, all multi. I'll give that a try and see if it works!

[Aontaigh]

I tried what you recommended, cores failed at my current voltage of 1.45V (230x20.5)

psssh mate suicide run, is my middle name I ran 1.6 volts to get my max clock and to make it the second fastest 8350 on the forum

I've done 1.55. The thing is it actually caused my rig to not post. As soon as I lowered the voltage I got a boot. Odd one that.

That's really good speed for 1.5 volts but I would be curious to see if it is actually starving for voltage.

 

Also it depends on the CPU if it likes multi or FSB. I typically find with 8350s that you can get about 200mhz higher with the combination of mostly multi and some FSB on the same voltage.

Could be a board issue with temp or voltage regulation. I had issues with one board above 1.520 volts. RMA'd the board and now the replacement has taken everything I've thrown at it very well.

58c while playing CS GO is uncomfortably high I would say.

61c is the absolute max for Piledriver, any higher and your cores may start making calculation errors which would cause both instability and performance degradation.
Go for 4.4Ghz and lower your voltage.

I highly doubt that your CPU actually requires this much voltage to run at 4.5Ghz, it's very likely unstable RAM that's causing your system instability.
Go into the BIOS and set the timings manually.

My FX 8320 requires SIGNIFICANTLY more voltage when I leave the RAM timings at "auto" because they're unstable.

My RAM is at 2100MHz 10-12-11-27-1T and I haven't encountered any problems. Running Prime95 cores fail even when I increase my clock speed to 4.7GHz at my voltage.

The maximum memory frequency the 8320 supports is 1866 anything above that will increase your chances of instability and will require additional voltage going through the on-die memory controller.

So basically that's your problem, under-clock your memory and your CPU will require less voltage at 4.5Ghz.

I've had several problems getting my 1866 memory running stable, let alone 2133.

The 9000 series FX chips handle faster RAM much more gracefully.

I do a lot of video editing (Sony Vegas), would bringing my RAM down to 1866MHz and increasing my clock speed to 4.7GHz be worth it?

I'm not really sure, if you work with really large video files it might actually help to have the faster RAM rather than the faster CPU.

Best way to find out is to test it out for yourself.

In terms of gaming alone would I see much of a difference from going to 4.5GHz to 4.7-8GHz and lowering my RAM speed from 2133MHz to 1866MHz.

That's kinda wrong. Core temps dont effect stability of cpu's and they won't degrade performance like you exaggerated, it'be more like the electrical pathways degrading having defective circuits and will never ever be stable anymore. There shouldn't be any difference in terms of performance running at 60° or 85°. The problem with FX is just the socket cant handle the heat once the cores go above 60° if I have to believe this thread at OCN. The CPU will handle 80° easily but the socket design is awful..

 

[Aontaigh]

Rather than using a synthetic benchmark I decided to use games as I don't see the point in monitoring CPU temperatures while running a synthetic benchmark, I use them to test stability alone. I played Arma 2 OA, as it's CPU intensive, for around 40 minutes and then maximum recorded temperature was 59 degrees Celsius. As a note, there was also things such as Skype, Steam, Dxtory, Notepad, etc. open. Is this temperature fine or should I push back to 4.5GHz or so and lower the voltage.

59°C is nice!

[Mecami]

Absolutely fine.

Personally I would be comfortable with anything below 70° C.

[helping]

Below 62c is safe. Below 70c for synthetic tests is safe. 

[D3MON]

only push for clock speeds if youve prime tested it for an hour and monitored the temps, ive had my phenom in windows at 4440mhz but that doesnt mean anything because it wasnt stable.

arma 2 isnt cpu intensive, ive run arma 3 and my phenom isnt maxed so your fx8 wont be, run prime blend or small fft and report back. you might not see any point in it but that doesnt mean there isnt one, you dont know how far you can push your cpu unless you know its stable and within temps (just because its at 59 degrees in this 1 game, what about encoding video or when summer hits etc?) unless your willing to buy another one if thise one dies in 3 months, just saying.

As I said, I used synthetic benchmarks (Prime95) to test stability and not temperatures because that doesn't make sense. Compared to other games it is.

Aah, I think you misunderstood.

If you run a stress test like Prime95 and leave it on for a while even if you had a stable overclock not long after you surpass 61c the CPU will start throwing errors.

And once the CPU starts throwing errors the performance automatically degrades because the cycles are being wasted on garbage results.

I'm not talking about performance degredation as in "Silicone" degradation and CPU lifetime.

Similarly if you run a test like Cinebench once with 4.5Ghz and temps below 60c and once with the same 4.5Ghz clock but with a voltage that drives temps over 60c.

You'll find that the first run was actually faster because in the second run the CPU would overheat and literally malfunction.

Games like higher clocks more than they do faster memory.

Possibly because the socket holds back or just theyre designed to do that. With Intel you don't have stuff like that except downclocking that can be easily disabled.
