990FX Killer, FX8350 Turbo (Voltage)

hello,

 

sry for my eng. it is not the best, hope it is understood.

 

Im already practiced in few forums and hope to be able to integrate my questions correctly.

 

 

My Rig:

ps : cooler master gx650 +bro

mb : 990fx killer (bios 1.5)

cpu : fx 8350 be 4.0ghz, without turbo* (cooler : silverstone nt-06 "customized")

ddr3 : kingston hyperx savage 1866mhz 16gb (set : 1866_cl. 9-10-11)

hdd : seagate constellation es 500gb, 7200rpm, 64mb Cache

gpu : evga gtx 970 ssc 4gb (without software)

 

My Rig Bios (manual "#-stock"):

SATA Contrl. : AHCI#

CPU Freq. : 200#

CPU Freq. Multipli : x20 4000mhz#

CPU Voltage : 1.3375v#

CPU Voltage Offset : +0mV

NB Freq. Voltage : 1.1750v#

NB Freq. : 2200mhz#

HT Link : 2600mhz

(only) : CoolNQuiet

 

temps in closed case (swing range) "Gaming/Videoediting":

100% load = about 68c

75% about load = about 55c

idle about load = 35c

idle = 14c

 

 

My experience with ASRock were always very good. Therefore, I chose a product that again.

 

over time and with interest I could some experience in OC etc. gather. ultimately to my current Settings.

 

everything is very stable that it's frightening in multitasking and to cause several days without any error. I am extremely satisfied with my hardware Moment.  except with my ps, which is pretty much at the swirling since fx 8350 be 

 

 

 

*My choice was the 990FX Killer because it has qualitative properties and be able to make enough adjustments to make any changes. (Unfortunately little bit because I'm not satisfied with the tensions of the turbo clock voltage)

 

this is unfortunately too high in p-state pb0 with about 1.4000 and p-state pb1 with about 1.4125 at my Settings. have already tried many things, for example :

 

AMDMsrTweaker : very nice ! but unfortunately not be considered.

AMD Overdrive : very nice ! but unfortunately not be considered.

 

Are there any other ways to change this? perhaps the ps?

 

nice it would be because I would like to have but like turned on the options as C1E, core c6, APM with Turbo up to 4.2mhz (or more). but always automatically sets the MB at the 1.4000. and higher, so that the temperature rises to 75c and higher !

 

so since I'm new, I hope that the information is enough.

 

EDIT : CPU Voltage 1.3625v from the temperature rises up disproportionately. about 10 degrees more.

I agree with PetrolHead, your CPU temperature seems high for the voltage you have set, 1.3375V.

That may be caused by your CPU cooler, and the way Silverstone suggests using it. The NT06 was designed to be used (in one possible configuration) without any fan attached to it, and located under a top mounted PSU whose fan is supposed to pull air across the NT06's fins to keep it cool.

That design is not good for use with CPUs like an FX-8350 that run at high voltages. Do you have a fan mounted on your NT06?

If you are using it in passive mode, meaning no fan, or depending upon case fans to move air across its fins, that is not enough.

We also do not know what PC case you are using, and how many fans it has in it.

I'm having a bit of trouble understanding what you're trying to say. However, looking at the pictures the main problem is your CPU cooler. Your CPU temp ("package") reaches 60 C, which is at the upper limit. The CPUTIN is the socket temperature and that should always be 70 degrees or below. The reason for its temperature is likely the lack of a top-down CPU cooler, where the fan blows the air down towards the motherboard. Unless you can somehow get some more cool air for the socket, you run the risk of cooking your socket even at stock speeds.

While the housing and case fans may have some effect, I doubt that's the main reason to your heat issue. The socket temperature tells me your CPU cooling is insufficient. This is what the specs of the NT06 Lite and NT06-E say about the allowed CPU TDP:

"Fanless with 120mm fan in PSU < 1000rpm - 65W*
Fanless with 120mm fan in PSU > 1000rpm - 95W*
Fanless with 135mm/140mm fan in PSU - 130W*
1 x 120mm fan 800rpm - 65W
1 x 120mm fan 1000rpm -95W
1 x 120mm fan 1200rpm - 130W"

The TDP of an FX-8350 is 125W, so that 120 mm fan you have under the heat sink needs to be spinning at 1200 rpm to be able to safely use that CPU cooler at stock speeds. Because of your high socket temp, I would suggest flipping the fan so that it pulls air through the heat sink towards the cpu. This may increase socket cooling enough to drop you below 70 C. Another possibility is to install the stock CPU cooler that came with the CPU (if you still have it). It should be more than enough to run the processor at stock speeds and stock voltages without the temperatures going over the maximum values. The downside is that it's a bit noisy due to the small size of the fan.

The bottom line is this: If you need to lower voltages to keep temperatures down for a system that is essentially running at stock speeds, the voltages aren't really the problem.

PS. Make sure you have decent thermal paste between the CPU and the heat sink.
