4670k overclocking

[bgt]

On a funny note. Be careful using the XTU utility on non Intel boards as a way of measuring. This is from my PC, and its not photoshopped It swings between anything essentially. I am sure I could make a CPU-Z validated too, if hit the botton at the right time. WR anyone?

Using AIDA as stress test shows the same 100C=throttling beheaviour. But I know the reason now why it does throttle. A bit strange adding something that throttles the CPU and using it as an extra in a new design.

Cache still shows 3.5Ghz? Then cache is Oced.

Nice read:thumbsup:

?, where to look if its OCed? In bios? As far as I know everything is on auto.

HT off. Wow.....this has an impact on the desktop speed.

Go run Handbrake and let us know if it throttles.

You won't find the code that is present in power viruses in real world applications.

Handbrake uses avx/avx2/fma3.

244fps, no throttling.

Why do you call them a virus while they are test programs you use for stability sake?
Is this ok? It throttles here also. Or is this a power virus too?

Because that is what they are, programs designed to run your cpu with a very limited scope of instructions for the sole purpose of generating the most heat so silly forum people will call them stress test programs.


You already ran one of the few programs that generates a real world boost of about 20% more performance using FMA3/AVX2 without issue, what more needs to be said?

I thought the problem with Haswell wasn't the mere presence of AVX2 but rather the stupid "helpful feature" of arbitrarily adding +0.10-0.15v when running AVX benchmarks? Why does it need that? People who have fixed the voltage manually and run same benchmarks 0.1v lower aren't complaining of lockups or "not enough juice", so presumably it doesn't really need the extra voltage at all? Why doesn't AVX1 (on Ivy Bridge's) need that?

To those of you with high temps, what's your temps like when using a fixed rather than adaptive / offset voltage? I mean write down your normal load voltage when running a non-AVX game, and then manually fix it at that in the BIOS / disable offset, etc, then run the AVX benchmark. Is it cooler / does it crash?

Here is my i3-4130 system with stock cooler. As you can see it throttles at default. Load is Prime95 FPU test

99c for an i3 is absolutely crazy. An i3-3240 at same 3.4GHz freq doesn't even hit 60c stock cooler under IBT / Prime. Is AVX2 really worth +40c temps (especially in real world usage)? Anyone know what apps use it and what real life (non bench) gains are? No way can that have the same 55w TDP as Ivy Bridge's with a higher voltage & temps.

You know what's silly? That Intels own IBT showed throtteling at a slightly OCed CPU!! After all...they sell it as a K model to be able to slightly OC it.

lol ibt isn't from intel...

Intel Optimized Linpack which is official is even worse though due to it so fast.

 

[frythecpuofbender]

I have totally given up on Prime95 or Linpack, Burntest.
I ran those all for 3hours+ each for my 4770K overclock to 4,4Ghz and of course they all passed, due to the increased voltage the cpu gets during stuff like this.
When trying to play some games like Tom Clancy's Future Soldier (2012, not too demanding) I got crashes all over the place.
We definitely need a new tool to test Haswell due to the adapted voltage it gets when using Prime95.
The only way to be sure that your preset voltage stays, is to set it to manual. But that means you are throwing away any kind of power saving that would happen when you idle, as manual would always have the voltage at e.g. 1.2v.

Just to see if I have a bad chip. I will test my 3770K now to see if this is normal under stress.
I wanted to buy an i7-4820 but was stopped by the old chipset. Pity.[/QUOT

Even 80's c is good for full load.

Enjoy your system. gl
