to delid or to not delid :) - Page 4

post #31 of 37
Guys, just remember that Prime/IBT Temps are NOT indicative of ANYTHING else other than Prime/IBT. I, and a lot ofppeople at ROG, have come to the determination that the only thing that these accomplish is to put a lot of unnecessary thermal load on chips, MOSFET's, and so forth. The link between P95/IBT stability and ACTUAL REAL WORLD sstability is tenuous at the very best.
The fact is that we are no longer forced to examine and reexamine every component when our computers have issues. BSOD dumps more often than not will provide not only the exact component causing problems, but even tell you what you need to look at (fix). Graphics issues are quiteeeasy to determine, and MemTest86 will provide far more in depth, vastly more accurate memory testing.

If you are looking for "bragging rights" of passing 24hrs of either chip cooker, more power to ya. However, I have been doing this a while (although there are quite a few members who have immensely more experience than I), and I have had chips that are Prime/IBT stable that are real world stable, but I would say that it is close to half of the other times, where the overclock will run the burn programs nonstop for as long as I care to torture them, only to crash trying to open Notepad or a game.

There is ONE thing that I have found that is an accurate predictor of stability, and that is to simply USE IT NORMALLY. If you game, run the most intensive games you have. If you fold or mine, run your Folding or Mining client. The worst thing that is going to happen (unless you are the unluckiest person ever) is a blue screen, which will tell you that you need more vCore/VTT/VCCSA/vDIMM/etc, or a hang up which is likely the result of too little voltage. Unless you are overclocking the BCLK, and willing to accept the risks (I do and am, bc my 3930K for example will run 100-245Mhz faster without any extra voltage) which includes the very real possibility of corruption, and so long as you understand where the voltage limits are, why they're there, what each does, and you don't exceed them, it's astronomically unlikely that you are going to damage your chip solely by overclocking.
What does cause damage, is too much voltage, or too high of Temps, and there's no reason to intentionally subject your processor to one of those, in this case very long periods of extremely elevated Temps, in fact I find it kind of contradictory to the intended purpose of the progra.


I wwould bet that if everyone here who is doing prime stress tests, instead of doing "real world use" stress testing, that you will find it to work at least as well, but unlike the chip burners, you are not torturing your chip.
I have not used any burn program in about two years, and I have found that the many overclocks I have performed, are at least as stable, but on the odd occasion there is a problem, I can only think of one instance where it took me more than a single trip to theBIOS to correct. That's Lord knows how many WEEKS upon WEEKS of actual computer use, instead of waiting for a burn program to tell me what I can find out on my own as fast or faster and without subjecting my chip to unnecessary, extremely high temperatures.

Nice post nleksan, and pretty true right enough. :-)

I have probably spent the last week or so not actually using this PC as a PC. But hey! I have had fun! rolleyes.gif

There are other reasons for torture testing though, in order to properly test the upper limits of my custom cooling loop I want to generate loads of heat in the CPU core. I also properly battered the poor little chip at the heart of my system while trying to get the lid off. Properly stressing it will (hopefully) prove it to be alive and capable or toast it.
(this is actually where my logic breaks down....in order to check if the cpu still works I am prepared to stress it and other components in my system beyond safe and/or practical limits. - I really need to have a quiet talk with myself.)

.....and then there are the bragging rights.

Mine is also a pretty hot runner if stressed with synthetic programs like p95. 4.5ghz on 1.267v, it will hit the mid 90's in seconds. But for normal use such as gaming i was seeing a max of 67c in my old bitfenix shinobi xl case, (very poor air intake). Ive yet to test it out in my new case in sig. Cooler is an alpenfohn k2 with dual corsair sp 120 PWM fans. Thought about delidding, but just decided to leave it as is. Just dont bother with stress tests. Use my normal tasks instead to test it with.

Yeah, my chip is also a terrible overclocker. I am sitting at 4.4Ghz at 1.25v, and if i go 4.5Ghz at 1.25v or above i get a bsod or it gets to 90 C rolleyes.gif . Oh well Luck of the draw i guess.
post #36 of 37
My first 3770k needed 1.328 to be stable at 4.5ghz
post #37 of 37
Holy crap! I delided my 4670k and now I am pushing 4.8GHz @1.43v , 85C under water. Drinking was involved , never had the confidence before. I used the razor method and scraped one cap under the IHS off... Seems fine though. Does anyone know what those do?

Edit. I guess it's more like 4.7ghz, 1.47 vcore. That seems the most stable. I'm doing a lot more tinkering and stability testing, then I'll try to validate.
