Use any Temp you feel comfortable with...Your parts.
This is as of early April 2013 not sometime in the distant past.
Motherboard >> ASUS M5A97 LE R2.0 ATX AMD Motherboard with UEFI BIOS
CPU >> Amd FX-8120
CPU Cooler >> Cooler Master 412S
Question:
Can anyone please tell my how to disable CPU throttling when its reaching 60C~?
Ive disables pretty much every power setting in BIOS and got good air flow inside the case with 4 fans. Everytime it reaches 60C~ the CPU downclock itself, really annoying.
The "core temps" are at that point just under 40C I think. So if its the "core temp" I should look at, why does this happen?
Answer:
Says it is able to run 8 core/140 CPU's however it appears to be a poor marketing issue why?
Well the $89.00 boards from asus are good quality entry level boards in my experience meaning you get what you pay for.
1. > The majority of entry level motherboards have weak power phase design 4+2 Asus uses quality VRM components but in this case I would not recommend a 4+2 phase non-heatsinked board to run a FX 8 corel
2. > We use the term weak when compared with the PRO or EVO edition of the M5A97 that has a 6+2 phase heatsinked design or the even higher performing line that uses 8+2 phases such as the Crosshair or Sabertooth 990FX.
Now to answer your first question it appears your bios does not have a feature to turn on or off over current protection, higher end boards under the digi+ vrm/power control menu have a feature that can be enabled or disabled called VRM over temperature protection the features you have likely disabled are really only to save power/reduce temp during idle stages such as C & Q, C1E, EPU etc... or allow sleep functions like C6 core state
Your system is throttling (dropping 12v voltage/multiplier) because the VRM components are over heating, power is being cut to the processor to ensure no damage to the PWM system or the CPU
The FX 8 core processors draw immense power (

Suggestion: With the 8120 you need OCP or you will eventually fry components....drop down to a 6 core or add passive cooling to the all the mosfets 4 per phase using MOS- C1's or the like. If using the stock cpu cooler airflow is being provided to the VRM components, however if using a tower cooler such as the Cooler Master 412S listed in your sig airflow is blocked requiring you to use a extra fan to cool this area.
Anyone who comes into the OCF AMD CPU Forum section and either gets help and stays and helps day in and day out or who comes to help and never asked for or sought help; it is these people that day in and day out that must deal with users and the cheap stuff. It is those people that deal with exactly the posting user above. In real life the questioner has little chance of overall success with his choice of parts and pieces when run as HE "thought" he could utilize his parts and pieces.
So when Bulldozer began to surface back in the fall of 2011, there were post after post of users asking the same question as above. Many boards were throttling due to VRM overheat and even UNTIL today there are cheap boards that throttle due VRM load that can be related to CPU socket temp. By the time the CPU Temp gets there the VRM has throttled the cpu. Did the cpu socket temp do the actual throttling? No, but the temp caused the need for higher Vcore and then you are in the more temp, more voltage more temp circle of trying to balance an overclock.
Previous to the FX release most of us that stay day after day, were suggesting 55c Core temp and 62c socket temp. As time has gone on and the good boards features have gotten more diverse, we have upped the suggested Max socket temp to ~70c and the suggested core/package temp to ~60c as viewed in HWMonitor free version.
And now we get questions about this BS at this link.
http://www.svc.com/am3-x1.html
First they say this >> AMD Phenom & Athlon II/AM2/AM3 Sockets Only << that is not FX at all.
Then they say >>*Please note AMD FX Processors and Indigo Xtreme AMD AM3-X1 re-flow issue << still not AM3+ stuff. AM3+ stuff is FX processor stuff.
Then they say >> AMD’s specification of 61°C-70°C is for maximum allowed case temperature (a thermocouple measurement taken on top of the CPU lid) << which AMD has said in open forums is NOT the truth.
And then they finish with this >> In the mean time we are declaring Indigo Xtreme AMD AM3-X1 -AMD AM3/FM1 as possibly incompatible with AMD FX Bulldozer series processors until we can confirm/disaffirm this. << Good idea since nothing about the product has said it applies to the AM3+ series of cpus which are the FX processor series of cpus.
The entire thing at SVC was BS and useless except you intended to buy Indigo Extreme TIM for FX when they said now don't do so. Did not plan on buying the stuff anyway.
So the individual that wants to run 85c core temps...have at it. Go for it. Heck run any temp one wishes to run. After all you are the one buying the parts and would have to stand for any failures. No one in the forum will stand for your failures. Don't let a little caution and or suggestion put you off from some air-cooled clock you think you can reach. Go for it. Get 'R Done.
For the rest it is still suggested by those that help everyday that you use some logic that has been developed over the last year and half of dealing with the newer AM3+ cpus, and that ~60c Core/Package temp and ~70c Cpu/Socket temps are still considered pretty safe and sane as max temps. Such for many reasons that are not just related to cpu life but having cheap boards that can throttle at low Socket temps and that to be able to push the high current thru the VRM you must DISable the safety features are some of the other safe and sane reasons for using the ~60c and 70c as Max temps for Core/Package and Socket/Cpu temps.
