CPU throttling !!! quite urgent - Page 3

post #21 of 136
Thread Starter 
without load line calibration when your CPU draws more current the voltage decrease you still get the same power output but potential difference across the chip gets sacrificed for more amps. FYI, silicon is a semiconductor, hotter it gets the more current it lets through.
if you want to calculate how much power ur using here is the equation.
P=IV where P= power I= current V=potential difference (volts)

you'll be surprised to know that your CPU draws about 30-40 amps.

that is alot ... but smaller P.D. compensates for that

Just an idea try putting a fan blowing directly on the vrms and check for throttling, i had a similar issue with my ud3 board ,but my board is known for being complete crap in that regard, after i put a fan blowing directly on the vrms no more throttling.

Ok first thing is first. What is your temps looking like. Download HW Monitor. It will give you a bunch of temps. I am interested in "package" temp and "socket" temps mostly. Those will be the most likely reason you are throttling. The reason I say this is I have the same board as you. I leave HPC mode on and I tend to throttle around the 75C mark on socket. I haven't tried with HPC off simply because it does not get hot enough.

CPU Current set to 130%.
CPU/NB current to 130%
CPU LLC set to Ultra High
CPU/NB LLC set to high.
Set your VRM frequencies to their fastest.
Set CPU power phase control to extreme.
As you say all your power saving features are off HOWEVER I usually run with HPC mode on. So give that a chance.
I see you said you have a fan on the VRM's? What sort of fan and how is it orientated. If you get the Stock fan from your CPU heatsink and mount it so that it blown ALONG the VRM sink instead of just down on your VRM's it could help as it will cover a larger area. See the pic I insert for clarification on what I mean. Lets see if we can't stop that throttling! thumb.gif

once again nothing on this board gets hot at all. during prime95 i touched every chip and capacitor etc. with anti static precaution taken of course. and nothing is hot

anyway Amazon is sending me a new board which will arrive tomorrow.

yet i don't know if i should request for a replacement for the CPU too

Falc0nPuls3 didn't start this thread to brag about his GPU but it appears that's the only reason you chimed in. BOOOOO


Even at 5ghz I bottleneck on the CPU in strategy games with my OLD GTX460. Even an i7-4770K@5ghz will be the source of minimum FPS caused by CPU bottlenecks in lots of strategy games and MMOs REGARDLESS of GPU choice (except something iGPU class like a GT610). This has been heavily tested and explored by enthusiast players who have tried all sorts of things to "solve" minimum FPS issues in high unit count mufti-player games. Changing graphical settings, resolutions, and GPU strength doesn't solve it. It's tied to CPU performance, and usually per-thread performance, an area that PD needs all the help it can get.

If I had an FX-8320 and a GTX650Ti Boost and I intended to play games, I would overclock the piss out of that CPU to bring up my minimum FPS and maintain real-time in strategy games better.



Cinebench can not be used as a stress test for piledriver (except to test the FPUs, but it won't tell you much about stability or thermal limits under any other normal workloads). That type of FPU workload is bottle-necked by the schedulers really bad so you'll never achieve any sort of high workload saturation. I can run near 5.4ghz in cinebench, but that same speed will cause immediate thermal instability and/or shut-downs in other workloads. To be honest I don't even like P95 as I find it doesn't achieve peak saturation either. For performance tuning and stability testing I always resort to compiling and trans-coding, as those workloads achieve extraordinarily high saturation levels and will typically offer the fastest insight into whether or not a PD chip has enough cooling, and whether or not it is stable.





Falc0nPuls3,

The reason for your throttling is CPU temps:



You're bumping up against the 70C mark on core temps, which is probably causing the throttling. The motherboard is fine, the CPU is fine... That particular little liquid loop is not a particularly strong performer, though I suspect that's due to the lower RPM fan it comes with. A quick lookup of how it stacks up seems to indicate that it is worse than many traditional 120mm heat-pipe towers, which means, not much better than the stock AMD cooler.

To get more umph out of the zalman, consider configuring your case fans to all blow into the case, and the radiator to exhaust so that all of the case fans are effectively "assisting" the radiator fan. I would also recommend using a stronger 2500+rpm fan on the radiator as that seems to be one of the biggest sources of performance variation among 120mm radiators. The cheap 120V that I have performs really well, but probably because it came with a strong performing fan.

Hmmm... Maybe a AFC1212D-PWM (Not sure if these work well on rads or not but 110+CFM! yikes! FUN!)

thanks for the effort you put in and the time you took biggrin.gif

the temps you see in the pic ,70c, is the socket temp not the actual temp of the cpu chip. that temp as you may know depends on a thermal indicator inside the CPU socket which is never accurate unless you buy a super expensive motherboard that manufacturer bothered implementing a good sensor in.
as you can see, the CPU temps on the cores are about 50 degrees under prime95 full FFT. the cooler is capable no doubt.

also in terms of FPS i went from max (110-120 to 160-200) min (60-80 to 100-120) at 4.4ghz.

also the maximum thermal junction is reported to be 90c on the cores.


i'm getting my new mobo tomorrow. i'll report back to see if it was a defective mobo or what.

thanks a lot again.

Thermal throttling that is induced by a motherboard usually occurs in the manner you have shown with forced spurts at the lowest power state to stabilize temps at the maximum allowed. It's my understanding that If any temp sensor be it VRM or socket hits that limit (70C for socket temps), It can force intermittent low power states.

Try getting more airflow behind the board and over the whole socket region and see if it stops throttling. I seriously think you're running into thermal throttling here and nothing is "wrong." You are only about 5C away from max core temps which means you're very near the limits of the cooler anyway.

You'll have to forgive me I dropped the ball on the "socket vs core" issue there (I'm used to 70C max core temps on FX-6300, saw "core" on the chart, ran with it). Regardless of my error, the fact remains that it's bumping up against the limit.


Keep in mind that "core temperature" reporting on AMD is algorithm based and usually off by 20-30C from actual peak junction temps depending on the chip and other factors. 55C reported core temps on an FX-83XX means junction temps ~85C, which explains how we can get socket temps that report higher than core temps (the core is not actually cooler than the socket, that's impossible).

as you can see, the CPU temps on the cores are about 50 degrees under prime95 full FFT. the cooler is capable no doubt.
For that reason, fan speeds and throttle temps are governed by the socket temp, not the core temp. And the core temp sensor isnt accurate until over about 40 - 45C.

Putting a fan on the back of the mobo, assuming the cpu socket area on the back is open and good air flow in the case(which looking at your case you do), can reduce socket temps quite a bit. smile.gif And can knock a degree or two off the core. It helps no matter the mobo or processor. Ive had a fan on the back of the mobo for a good 10 years.

In my case, my socket temps are 4 to 5C less than my core temps. Looking over other setups, I seem to be just about the only one who has less socket temps, so maybe my temp sensor circuit on the M5A99 is whacked out going the other way, heh. I'll take it though, as I never throttle. smile.gif
