4800mhz fine, 4900mhz no ?? 4790k

So guys, i've finally tweaked my cpu...
4800mhz_1.30V/cpu + 4600mhz_1.31v/cache (1.95V vccin under load)
Super stable, aida64 stability test 7hours.
occt:cpu_large data set = 1hour stable
occt:linpack = 1hour stable
Cinebench loop,xtu bench, aida64 benches, pc and 3d marks..etc..
All this with 70-85C max(delided cpu). No crashes/freezes whatsoever...
Now, the problem is 4900Mhz. Cant get it stable even with 1.4V. Thats 0.1V increase but only 100mhz gain..
Tried vccin 2.02 under load and didnt help.... Can run aida64 stability test for hours, can do XTU for hours too, can do cinebench loops, wprime 1024M etc... But in occt:cpu it crashes to bsod in 5 mins.
Any ideas ? What might help, or should i "idgaf" about occt lol ? Is aida64 nuff?
I can get to 4.8, but the thermals get a bit high for me. That's at 1.360Vcore. I'm not willing to even bother with one that exceeds 90C in P95. For me, 4.8 is awaiting the H110i GT or a custom loop. The most I can push the thermals at 4.7 is the mid 80's in P95 with the H100i GTX. Delidded.
I can do light stuff at 4.9, but haven't quite found the voltage for it, and it's also like yours approaching or above 1.4V, also it will still BSOD under heavy load.
I have a validated 5.0 GHz (see my sig), but it BSOD'ed right after getting the validation. I bet I can do it, but not with this cooling system, and probably not until I get a custom loop, and at a higher than 1.425Vcore only.
I normally run at 4.6@1.245V or 4.7@1.295V for my 24/7.
Don't complain! 4.8@1.3V is VERY respectable, and blowing the bell curve!!!
from my experience it doesnt dry on core-metal just on metal-metal contact. and hey...its PRO not ultra
The ultra is supposed to not make the stuff harden/stick like pro does. I haven't had issues with it myself. Just don't go over the eutectic point of Nickel/Gallium, it is actually below the shutoff point for the chip. I did up a post, including images from the ASM Handbook (the transformation diagrams) over at overclock.net I'll look for it this evening and post it here.
Slightly off topic but this post led me to a thread related to IC Diamond24 paste which give unexpected results and quite an interesting bit of drama with beta testers hehe.
IC Diamond will severely scratch bare silicon. Good results, but it damages the die. CLP and CLU have no alloying properties with silicon, and simply need isopropyl to get it off clean.
My new cpu
4790k@5100MHz_1.35v 24/7 STABLE
Schweet! Did you buy that from "Silicon Lottery", or was it just the luck of the draw?
