By the way I've seen my chip (when it was 3.8Ghz) hit 68 deg C while rendering, it may have been throttling then, I wasn't monitoring. I started seeing the throttling when I put the cpu on liquid and started clocking it up. That's when I read somewhere about enabling HPC. Ever since I've enabled that I don't get the throttling. If I've gone too far it crashes. I've had very few bsod's but there have been a few. Again I know the reputation of this gigabyte board, but I love the dual bios. When I started overclocking 12 years ago with a FX55 I got bsod's all the time. That chip had very little headroom and was finicky. But I was constantly clearing the cmos, and that was the first thing that impressed me with this board (dual bios). In fact, I've never had to clear the cmos on this board.

Well, pulled the computer apart and put back together. Rearranged some fans and set up the radiator for push/pull and had some of the fujipoly extreme tape 1mm on order. I put that on the vrm block and NB block and took some of the 2mm regular fujipoly that was on the vrms and placed it around the NB under the block. Got it up and running. I was able to hit 290Mhz fsb but couldn't get the cpu over 4.6 gigs. I tried 280, 270, 260 and points in between but couldn't keep it stable at over 4.6Ghz. I could get it to post and load into Windows @ 4.8+ but wouldn't make it through occt or prime without errors or crashing.
So I'm back at 256 right now at 4.6 with modest NB and memory over clock. I've got 32gigs of Gskill 1600 sniper series which has no problem at 850 (1700)MHz but completely locked up at 900 (1800)MHz. I had to take half of it out just to post to bios. Upped the voltage to about 1.66 or so (bios vs actual is a little different) and could get it to load up with all of it but it would crash when stressed. Such are the limits. I could probably loosen the timings but I was keeping them @ 9-9-9-24 1T for this go around. The push/pull on the radiator dropped about 10deg C off, so temps were all good under 51 even with the small data tests and about 46 on all other data set tests (occt, prime). Hell before I pushed the multiplier up when I was at 270-280 I was at +.050 on Vcore and was running in the high 30's under load. At 4.6 I'm at +.100 (1.52-1.546V). Til next time.

I had the same problem and I know the reason
Despite the fact that the temperature is displayed supposedly normal, throttling is due to overheating. After I improved the cooling, throttling did not arise.
The temperature readings are incorrect. Just look at the minimum temperature, seriously 23 degrees? This can not be, unless you use liquid nitrogen.

23F that may be true, but idle temps of 23C is perfectly normal for any CPU with a decent cooler.

The core temperature is lower than the body temperature? biggrin.gif
post #106 of 112
in my experience typical CPU core temps at idle are usually between 20-30C depending on the CPU and the cooler you're using. 24C seems like the most common average idle core temp. After years of becoming accustomed to monitoring temps in Celsius I can't convert C to Fahrenheit in my head anymore without having to give it some thought. But yes, typically idle temps aren't much higher than the rooms ambient temperature.

In any case, I had exactly the same situation, after 5-10 minutes of warm-up, the CPU was falling into cyclic throtting, the multiplier was 7x for a few seconds.
I did not understand why. While the temperature was only 52 over the temperature sensor, HWinfo, CoreTemp, OCCT, Showed the same temperature.
The problem was solved by an additional fan.

Throttling on 52C




After improving the cooling
Not more than 50C and no throttling

AMD FX temperatures at idle can be anything and are best ignored. Example:

Note the CPU 0 temps.

Throttling like that is the motherboard overheating and is very common.
post #109 of 112
Dropping to 7x multiplier is usually the motherboard trying to save itself, the VRM is cooking.

FX die temp sensors are way off at idle. To the point that they report sub-ambient.

If I put radiators on mosfet, chokes, capacitors, stability will increase?
