thank you for your opinion, so i stay with my overclock because i`m happy with that, also i haven`t delided so my temps on stress goes to 80c, while gaming 60~70~, `im using h100i and big pc case with good ventilation and also agree that if it dies within 2-3 years that would be a good reason for upgrade..

44x for cpu, dont change ring ratios and voltages till u find lowest voltages for 4400mhz on cpu

change vvcin to 1.900v, got same cpu and mobo, i was table at 1.280v core and 4400mhz

guys is it safe to keep 24/7 those voltages, max temp 79-81c durin stress test, wont it degrade CPU? (my cpu 4670k) cpu 47x 1.360v ring bus 44x 1.320v vvcin 2.000 found super stability, 14 hours of intel extreme tuning utility also will enable low power features

hmm yes, i found stability at least for 4 hours when increased cpu input voltage to 2.0 now i`m running intel extreme tuning utility i5 4670k vcore 1.340v 4700mhz cache 1.280v 4400mhz vvcin 2.0 max tems in Core Temp was 78c this combo of 4700core and 4400cache showed best results in benchmarks, example i could hit 8.06 in cenebench with cache 4600 i cant get more than 8.04.. i dunno why, 4500 showed same results so i left cache at 4400 thus it uses lower voltage, anyway to hit 4700 core with lower stable voltages i needed to increase vvcin to 2.0, will try lower it if i`m stable for 8h

again me, posting further results. 4670k and msi z87 g45 will try to lower volts, my temps about 70c~ in stress test also OCed my ram (xmp profile let chose only 1600, i have those to work at 1866) (hmm can`t upload any image in gallery.. any1 know why?) core 4600mhz - 1.330v cache 4400mhz - 1.310v vvcin - 1.900v btw at cache 4200mhz can keep it at 1.210v and core 1.220v at 4400mhz, tems 60c~ dunno if 200mhz worth it

in bios when u click with mouse on auto table of mhz`s appears, select 1333, i tried set clock from auto to link ans made it 9-9-9-24 (by manufacturer) then changed volts to 1.5 in bios it posted as 1.505 vvcin auto core 44x core volts 1.250 that how it worked for me first time, 10h in intel extreme tuning utility for a night maybe u need to increase a little vvcin? what was your default? mine 1.780, try set manually to 1.880 maybe

thank you, i`m really happy with x44 and 1:1 ratio, don`t think i`ll need more. even at default 4670k is great processor for gaming

set ram clock manually and make ram voltage 1.55 it helped for my stability

Hello guys i`m new here, my system is: Mobo - MSI Z87 G45 Gaming CPU - 4670k DDR3 1600Mhz cl8 1.5v ssd 120gb hdd 1tb GTX 570 PSU - Corsair CX750w So my stable oc is: (tested with intel extreme tuning utility 8h) core multi x44 core voltage 1.280 cache multi x44 cache voltage 1.280 RAM all auto with x.m.p profile 1600Mhz 8-8-8-24, auto voltage 1.5v PCU input voltage (VVCIN) 1.9 V cooler h100i temps don`t go higher than 69c 64~ average i can`t run system if i get cache voltage to 1.270, 10 min and all freezes with stesstest in intel extreme tuning utility 1.)are those voltages ok? 2.) what are safe voltages for core and cache? i want to get 1:1 on 46 multi, 3.) does cache speed really impact performance so much? thank you
