I mean the only stuff they say about overclocking is that the chip throttles and can't OC for heavy loads. If that's not far fetched then I don't know what is.


All they said was that Prime95 was not a good way to test because it no longer causes the system to fail, it just causes the CPU to throttle.

I didn't hear him say "Since Prime95 doesn't make it fail we won't be able to overclock it what a fail!"

And they should know that if you throttle your overclock has failed. That they say prime isn't good because it throttles the chips is mind boggling. They're saying that a stress test isn't good because it did its job.

Stress testing 101.

He doesn't expect them to OC as in he doesn't expect them to OC well. Which from what I have seen, they don't. You're taking things WAY too literally.

He said Prime isn't a good way to judge because it doesn't fail like Prime traditionally would.

I still haven't figured out how to play with VIRN and how it relates to vcore.

So to de-lid, all you have to do is carefully pry off the IHS, clean the excess glue and TIM, apply a new substrate like coollaboratory liquid ultra and remount your cold plate?

Will the load spring lever still hold the CPU in position?

Will the liquid ultra fill in the area left by the IHS?

If its that simple I'll mod my 3770K. smile.gif

Hammer and vice method. Go look on the Intel CPU subsection for the "Delid without razor blade" thread.

Prime doesn't count, you won't get ANY type of workload to ask the same voltage and produce the same heat as prime 95... I don't see why you would use it because no workload for the cpu will come close to the heat it produce while running. No one buy a cpu to run prime 95. On top of that it doesn't hit the system everywhere, it's really a specific one so stability isn't even tested.

http://www.youtube.com/watch?v=ub6WnHmiIOs

Asus did over 550 haswell cpu test and that's pretty much what he says and it make sens: Why would you use prime when it doesn't provide real world heat load and it doesn't really test stability. Sure it will make your cpu get hot but nothing else will do it, so it doesn't count as useful test imo.

edit: I'm retarded and can't read your post, never mind you said the same thing.

Maybe he didn't knew some essential things about Haswell, maybe he did. Sure thing is: Haswell affects Prime in an essential way. Using Prime with AVX, Haswell ups the voltage and then screws with your OC, but instead of just BSODing, it downclocks-throttles in its automated and mobile way. biggrin.gif
Quote:
Additionally, Haswell has a more specialized point of consideration for synthetic stress tests. When using an adaptive VID,

voltage levels will be automatically increased by the iVR when AVX instructions are detected from an application. An example is noted below:


A defined voltage of 1.245/1.250 would produce a CPU voltage of 1.245 or 1.250 under a normal realworld multi-thread application under load.

Using the same defined voltage of 1.245/1.250 but running a synthetic stress test like Prime 95 with AVX, produces a CPU load voltage of 1.370.

This increase must be considered as it could induce thermal throttle and overwhelm the cooling capabilities of the thermal solution being used.

Taken from ASUS Haswell OC Guide RC. Since I'm no Intel/Haswell expert, I would think that you can bypass this by using a fixed VID. But there they go your so precious Haswell power saving features and power consumption wins. Unless you can set the VID for the different states...as I say, I'm no Intel/Haswell expert so feel free to correct me, village people. biggrin.gif

Whats this about? Haswell overshoots vcore by .1+ when stresstesting?
