So a quite a while ago i wrote a long rant about how impossible my CPU was to overclock and what. Tonight i went back on the workbench with it and figured no way this POS will get the better off me. I succesfully OCed it 4.2k no worries, could proberly even hit 4.3, and it runs like a dream. Albeit originally i dismissed the posibility of OCing it since i tested the OC by running syntetic test like prime95, and what ever where you essentially burntest all cores at max load. When i pressure all cores the CPU throttles like nuts, i mean 4.1 throttles to 3.4 heck i've seen it hit 2.5Ghz on max load, and the benchmark results are VERY noticeable. SO figured tonight i'd give it a non-burntest shot and see what happens. At 4.2Ghz while just focusing on single core performance, atm playing witcher 3. And no throtteling, no problems, no nothing, infact a stupid gain. Im abit pondered at this. While running syntetics the thermal hits approx 68-70 degrees celcius at most, not sure of the temp while single core, performance but im guessing it is alot lower then full load. Any ideas whats going on?
The result should be more or less the same, i can actively see the CPU throttle like nuts through ASUS's tool, and task manager. Tried several syntetics to test it. But running single core performance(Like games) the CPU OC's like a champ, i mean i didn't even bother burntesting today no test, it just runs. Tired Prime95, and whats it called, the one linus allways use to test cores performance where you generate a image dependant on cores, forgot its name. both causes throtteling down to 3Ghz and below. Playing wither 3 at 4.2Ghz just runs butter smooth. at a temp of like 50 degrees on the CPU, no throtteling at all, and there is a deffinate gain in FPS.
Prime95 overvolts the CPU and is an outlier in that regard. Other stress testing tools don't do this as it isn't realistic. Prime95 was wrote ages ago and isn't made correctly for current generation hardware and thus is not indicative of the actual thermal performance of modern CPU's.
Prime95 is the issue. It is a terrible test and should never be used. It actually pulls.more voltage than you specify and can cause serious problems and even damage to your components.
AID64, ASUS RealBench, and others are better options.
As you can see if i'm running full load on all 4 cores at a time it throttles like crazy. Granted AIDA is not as bad as i expected, since prime95 throttles me all the way down to 2500 Mhz at times. But if i'm just gaming while overclocked. e.g. using only a single core, it runs like a dream, no throttling, and temps hitting approx 55-60 degrees. TBH i'm kind of happy with it as it works now, but i'm really just puzzled at what's happening now rather than anything since this machine is pretty much just a gaming rig.
What cooler do you have on it? Those chips do tend to run a bit hot, but that's to be expected when its a full-featured, and not completely shit, graphics processor and CPU all on one chip...
just some standard not way expensive cooler, i think it's a cooler master or something. But as you can see in the screenshot, it's not a thermal problem since at full load it hits approx 66-68 degrees while clocked. The throttling starts wayyyy before it even hits 65 degrees.
Get some real tests then, Synthetics are not really worth anything anyway, if it is messing up with actual work loads then you have a problem. but if all you want is a number on a score sheet at the end there is always photoshop.
Like i wrote earlier, it's not really fixing the problem that's why i'm asking, basically it does what it's suppose to atm. But im hella curious cause i spent hours trying to get this working, since when ever i OCed ofc the first thing you do is run a burntest and see if it crashes. And when the first thing you see is that it throttles like nuts, that kind of a proof it doesn't work. Turns out it doesn't throttle, except on synthetics/burntests. Works like a charm in games, compressions and what not. But god forbid i run prime95, aida, you name em, and it throttles. It may be thermal, or power related, or maybe even little pixies who lives somewhere on my MOBO, i got no idea hense im curious.
Thats fair. I do not really have answers, but some ideas. The synthetic benches are doing something that normal applications don't. I know you answered all this before but are they running all cores 100% and games are not? What do they do or change that normal loads do not?
