One other thing, is its possible your pump isnt working great on your cooler. if you can try a different cooler might be worth it to see if you see a difference.

with pumps, the water that gets warm, has to be pumped away, and new cooler water must take its place, if the pump is struggling, maybe that could be the cause? If you have the pump plugged into a fan header on your motherboard, make sure in the bios, you have that fan header set to FULL SPEED, and not normal / or temp based, cause maybe it will cut power to your pump?

i had an issue where my pump wasnt pumping at all, and my temps would start low, and slowly work their way up to 100c ouch!

Today I received Coolaboratory Liquid Pro and I applied it directly between core and IHS. Between IHS and radiator (Kraken X61) I set again Arctic mx-2 (sometimes I pull off coler to clean my PC and I want to have serials number and processor name visible, with CLP it would be difficult).

I raised slighty my Vcore to 1.28 and made a 30m test in IBT. Result?
Before: 78°C
After: 58°C on hottest core (average 53-54°C oduring streesing in IBT)

I think if I would apply CLP between EK and IHS aI could drop +-5°C too.
So... now we can overclock smile.gif

I have a question about my PC. I have a 6700k clocked at 4.6 at 1.32v with 16GB RAM at 3000 manual speed (no XMP profile). It is stable in IBT for many hours. When I try to put it at 4.7, at whatever voltage, my PC hang or crash with whea and watchdog error.

Is there something I am missing here?

My board is a Gigabyte Z170x Gaming 5, LLC at high. Btw, my temps never reaches above 70C with a Corsair H110i GTX. Also, my Uncore is set to 40. If I set it higher, my PC will have some difficulty to boot...

figure each 100MHz cost ~ 10mV per core, so on a 6700K increasing frm 46 to 47 multiplier will be somewhere around +40mV over what was stable at 46. And.. ibt is pretty useless for stability testing. Thermal management - yes, current peak, yes... but not as a processor logic test. Use x264, handbrake, or OCCT if you like high temperatures. thumb.gif

I tried but as soon as I reach 1.38 v, my PC hangs or crash. At 1.36 it is not stable enough. I am kinda stuck here...

At least it is a good OC with low Temps!

You probably just hit the voltage wall on your chip, where the voltage requirements just go exponential. Not every chip can do 4.7 at low volts.

OK then in OCCT, is there a way to know what when wrong when the test fails? When an error is detected?

C-states are a bit misleading.. the voltage drop is only because of core idle/park, the active core(s) will still receive the override voltage you set in bios. either use offset or adaptive. and with adaptive, c-states are best left disabled. thumb.gif

not sure I can help much with that MSI bios, maybe others here can chime in on Adaptive voltage with MSI.

Man thanks a lot for the information. I learned a lot. Why is parking cores not recommended if I'm gaming most of the time? And why is combining adaptive and CStates NOT a good idea? Most of the plebbit posts I've seen say that enabling ALL of those at any combination is fine

I like IBT because it gives me the highest temperatures (and without enablind "Xtreme mode" - right click on "Start" to enable). Prime was +-3°C lower and OCCT anoither -3°C lower. I found stable processor with multiplier x42 at 1,28V (1h Prime and 10 runs with 14gb ram IBT) but before dropping down temps with CLP.. Maybe with cooler CPU I cna drop voltage a bit more. Didn't check yet.

What is this x264? I heard multiple times about that stressing method (encdoing video?) but never found that "program" or method how to use it.

With adaptive and all c-states enabled, the voltage can drop so low that core waking can be slow or cause a system hang when a load demand cannot be met quick enough. Core parking will cause stuttering... the park-wake cycle is pretty inefficient especially when you are setting pretty high overclock. Plus, I'm not sure why one would want to park cores on an overclocked rig? If it is to save power, then use adaptive; the cpu will idle at less than 20W (vs 40W in manual override)... the cpu is probably the lowest power draw in a new(er) rig. Best way to reduce the voltage to the CPU and save power is to either sleep th erig, or better yet, shut down (which is good to do anyway especially after a gaming session - flush out the junk in cache and pagefile).

Yep, IBT tests the thermal limits of your cooling solution, and most IBT failures are temp related and not "problem-solving" related. It really is something from the cretaceous period. Too many folks confuse heat generated withg the "toughness" of a stress test. You can cook a CPU by simply hammering the FPU with AVX or FMA3, never really testing the rest of the architecture. Link to x164 stability test: https://drive.google.com/open?id=0B7gpMyj43ZFjSzJ4Nm0xT3pobjA
or read post #1 in this thread - dark-wizzie did a great job!

Best thing to do is mix the testing strategy: Realbench, x264 (or 265), AID64 cache stress, and HCi Memtest. Punishing a cpu with p95 is just not smart IMO. thumb.gif
