FX-8350 idle 60c degrees +

[Rnato35]

Hi guys
Im having some problems with a FX-8350 CPU, heres the case:
Two of my friends just bought to slightly different computers with the same processor. Friend 1 has no problem, running idle at 40° max, but friend 2 as soon as he starts the computer it goes up to 68°, he already had his power supply changed becaused it burned. Both of them are running stock coolers so i dont think thats the problem. I monitored both of their computers with Hardware Monitor, as you can see, the CPU Vcore of the hotter is on 1.33 and the cooler is at 0.99. Also, in terms of voltage, the hotter one is always higher. Also, i've already clean the whole case and re apply the thermal paste.
Any ideas of what may be causing this?

Friend 1(Cooler) pc specs:
CPU: AMD FX8350
MB: gigabyte ga-990fxa-ud3
RAM: x2 fury blue kingstom 8gb
VIDEO: NVIDIA Geforce GTX 960
Power supply: Thermaltake Smart 750w bronze

Friend 2(Hotter) pc specs:
CPU: AMD FX-8350
MB: Gigabyte ga-970A-D3
RAM: x2 fury blue kingstom 8gb
VIDEO: r9 270x
Power supply: Thermaltake Smart 600w bronze


ill leave the HW monitor screenshot.

there is definitely a problem there. AMD cpus shouldn't load higher than 67C or they will throttle.

Are you sure you removed the plastic film over the CPU cooler base before installing? And it is clipped on properly?

 

[americanbrian]

WOW, your supply voltages are WAY out of spec there.

The problem is your friends (Friend 2?) motherboard. It is likely a 4+1 phase model and will throttle the hell out of the CPU.

From the brand and model you listed (Friend 2?) (AMB 970 am3+ slddr3gb), I can't figure out which motherboard that is meant to be.

Yeah i definitely removed it, double checked everything is clean and good to go.

HWMonitor is unreliable with AMD FX CPUs. Download AMD's Overdrive and tell us what the Thermal Margin is.

The 65F temperature on the cool system looks like it will be below ambient, so is very suspicious. Is one in a very cool room in winter?

 

[americanbrian]

Either the PSU is not connected or functioning properly or there are some serious problems with the VRM's on the mobo. Voltage regulation is non-existent.

You can see at the top on Temperature -> CPU that it is on 38°C(100°F), also thought it was weird

Also you are clocked at 4.2Ghz on all cores for the hot one. That is not normal (even with turbo it should not be doing that on all cores). Have you set the bios to defaults? I suspect someone has been trying a bit of OCing there.

wops my bad its a ga-970A-D3, doenst throttle means that it will lower the cpu speed so it doesnt burn?

Can i configure it in the BIOS ?

I dont think anyone tried overclocking the cpu since its new. Going to set bios config to default and let you know.

update: Reseted the BIOS to default, its better now(iddle 25°C) but everytime i open any program it will go up to 70°C pretty fast an then back to 30-45°C. Also the cores speed went down to 1400Mhz and when needed goes up to 4200Mhz.
Voltage Vcore also went down to 0.9 and 1.4 max

update 2: CPU now at 68°C with some low-usage programs.

The D3, Versions 1.0 through 1.2 lacks heatsinks on the VRM of the motherboard and are completely unsuitable for overclocking a FX 6300, so completely out for even running a FX 83xx. Even with heatsinks (versions 1.3 or higher), the motherboard is to 'light', with too few power phases to run a FX8350 at stock.


The VRMs will overheat and limit the power delivered to the CPU.

I saw theres one(or two) little heatsinks in the motherboard. Anyway im going to check that out, ill let you know thanks!
