thanks for joining the crew here! hope you will share and enjoy here as much as possible, feel free to came up with comments and opinions here !
i'll swap mi system this year, 1151, having on plans 5.0GHz on a wonderful 6700K, still deciding about motherboard, and ram, but still have time, so opinions are welcomed!
Regards,
Your i7 3770 is still quite a powerful CPU. If you plan to buy a new (unused) i7 6700K, good luck finding one which can hit 5,0 GHz. Very, very few i7 6700K's are capable to achieve stable 4,9 and 5,0 GHz OC without surpassing 1,42V.
Average i7 6700K should achieve stable 4,6GHz@1,35V while good examples should reach 4,7 GHz without surpassing 1,365V. My needs minimum 1,375V for 4,7 GHz to pass 30-minute Prime95; it is possible that I would need 1,38V for marathon 12-hour test but I don't want to torture my CPU that much. Very rare gold samples are capable to reach 4,7 GHz without surpassing 1,35V mark.
The funniest thing when I OC'ed my i7 6700K to 4,7 GHz@1,365V is that everything forked fine for a few days without crashes, freezes or blue screens, starting from FC4, Wolfenstein TNO, several light CPU-z tests, video conversions etc, while Prime95 stopped it in a few minutes.
Mine can surely reach 4,9 GHz, but I need 1,39V just to boot into OS and run light CPU-z test, since with 1,38V it failed to boot and with 1,385V it crashed after a few minutes in Windows. Note that I had XMP enabled the whole time and OC was on all cores. If nothing else, at least my i7 6700K is produced in 2016, since its second digit (bottom left side) starts with 6. Week and batch numbers are classified.
I owned a 6700K, bought it in November but in January i bought a 7700K, the 6700K was the worst CPU i ever had, max OC was 4.6GHz 1.364V, i did all possible settings/tweak but i never got it to work above 4.6GHz, i tried 1.40V/1.45V/1.50V but nothing worked it just refused to OC higher,
it was a Nightmare.
There are even worse chips. I read about few "platinum examples" which need 1,4V for 4,6 GHz, while 4,4 GHz OC is their max without surpassing 1,35V. Yours i7 6700K could qualify as "Intel's finest platinum edition CPU".
