FRONTPAGE Intel i7 4790K Devil's Canyon CPU Review

Looks good but when you run Prime95 28.5 then temps will hit 95-100*C. I have about the same. It's passing XTU ( which is like older Prime95 ) or AIDA64 at about 75*C but in the latest Prime95 temps are going up to the point where CPU is losing stability. Maybe your cooling can keep it at lower temps under full load.

yeah not your watercooling, just tim1 issue again. Be interesting to see what one of the good clockers do on cold, post your results if you do it. And even though you used 28.4 without fma3, wont take much more vcore to make up difference.

My chip on dice looks like:

~5.3GHz ~1.45V Cinebench R15/11.5/XTU
~5.4GHz ~1.47V Cinebench R15/11.5/XTU
~5.5GHz ~1.50V Cinebench R15/11.5
~5.6GHz ~1.55V Cinebench R15/11.5
~5.7GHz ~1.62V some other benchmarks
~5.8GHz ~1.70V some various 1-2 core benchmarks or light 4c+HT like hwbot prime
~5.93GHz ~1.75V max clock and Spi1M

All results with memory @2666-2800 10-12-12-26 CR1. My Samsungs can't run CL9 even at 2.05V.


Cinebench R15 result below. Spi1M is somewhere on other drive so will post when I copy it.
I was checking CPU up to 1.8V ( which was max for used BIOS ) but I couldn't make Cinebench pass at higher clock than 5.6GHz.



I also noticed that on my mobo 1st slot is not working with memory at 2133+ and x28 ratio for memory is not working at all even though it was working when I got this mobo. x29.33 was too high for my memory so I had to use various straps to reach 2800+ memory clock.
I have no idea what happened with my Z97X-SOC Force board but it's going to RMA soon. I already got ASUS M7G. So far max memory clock is slightly higher but have to work some more on settings.
