FX-8350 Voltage

post #1 of 52
Thread Starter 
So I am currently getting my system up and running with all my programs again since fresh install. CPUID's Hardware Monitor is telling me the volts for my fx8350 are jumping between .83 to 1.42 for something such as installing WoW. My temps just for installing WoW have been:

Core according to hardware monitor - 11c to 46c

Actual temp - 22c to 58c

These are stock settings! Is the voltage jumping around like this causing this? What should the chip be at? I have changing nothing in the BIOS except for DDR to profile 1(to make it 1600). Everything else is on auto.

Edit: I just checked Gigabytes website for my mobo. They have updated the f7e beta bios to just f7. I will install it after class tonight.

Those should be fine. My 2500k also fluctuate even in idle speed, 0.99 to 1.050v that cause cores to go between 29(lowest core)-37(highest core) to 33-40 in idle.

Try disabling either c1e or cool'n'quiet or both and see what happens. One of them give OS to cause more inbetween speeds like 1600-1800-2200-3300-3800-4000 etc, also cause voltage to fluctuate more according to speed.

That was also the case with my Thuban.

I will try some different settings later tonight. My thought process is that if it is hitting 57 or 58 during something such as installing a program at stock speeds, how will it react when I start overclocking. At the moment I don't have much room at all IMO but I could be wrong. Thanks for your input though. I thought about taking the CPU V off auto and setting it to a fixed number but not sure what that should be or if that would even do anything to help it. Maybe the new BIOS update tonight will help me.

I just installed the F7 bios but don't have a piledriver. However I'm curious how the pd will oc now with F7. People with F7e (beta) were having problems oc'in and pumping a lot more voltage to get same oc's as on asus boards.

As far as what temps should be stock not sure. People oc'in to ~5ghz 1.4v-1.5v with high end air or AIO coolers are getting around 50-60C I think.

Well, with my voltage changing as much it does and going up to 1.45 or so during Prime95 earlier it makes me wonder if the mobo is giving it too much. I have been trying to find what the stock voltage should be at or close to for that matter so that I can maybe change it and see the results. I have another thread that I started last night about some funky stuff going on with Windows xp during my setup process.

http://www.overclock.net/t/1319806/bsod-with-8350

One of the lasts post was someone saying that the message I got during the BSOD was low voltage for cpu or faulty memory. But that seemed to only happen with Windows XP and has stopped with Windows 7. Thanks for your input!

So, I disabled C1e, C'nQ, C6, and APM. From my understanding these all regulate the voltages for the chip. So I wanted to see what would happen by turning them off. After I started up I saw that the my voltage was sitting at 1.3 and for 1 test of P95 it never got over 1.36v. BUT, my temps during P95 got up to 57c-60c with a 49c core temp and stayed in that area during the test.

I feel like this is too hot for a CM212+ with some PK-1 compound but this is my first FX chip. Does anyone have any input? I am getting worried I will not be able to overclock this thing now. I sitll have turbo enabled and I put the latest BIOS on tonight (F7 from F7E which was a beta).

But now the chip is idling with all those features off at 26 with a 14c core temp.... I dont get it...Is this normal?

EDIT: Don't forget, these are stock settings! The only thing I have changed as far as timings are for my RAM profile which takes it from 1333 to 1600.

Hold up a sec, which field in HW monitor are the cpu temps? I know core at the bottom obviously but in the fields in the top?
post #8 of 52
Just keep core temps under 62 and you'll be fine

I have been mis-reading the fields. Since i have a Gigabyte board I assumed the tmpin2 was the CPU but its the northbridge. I am good now and sorry about my noobness... lol

There has been much debate over this topic. However I'm still a firm believer tmpin2 is CPU and there is NO NB sensor. Just mobo sensor, VRM, and CPU.
