Hello guys, i do a quick presentation of myself, im Steven im from italy im 29 years old and i recently upgraded my computer.
Im searching for the right settings about a medium/high overclock of the cpu but i also want it more stable as possible, even if the "hardest" game i run on this computer is Starcraft 2 heart of the swarm and it hasn't very high requirements and it didn't employ cpu very much, i rarely run heavier games, i mostly run it or i use internet so i didn't stress my computer very much usually.
I have just at point an intel i5 haswell 4670k, i have closely no knowledge in overclocking and i did tryouts by myself.....i don't know much about voltage and im not pretty sure even about other settings i saw into the bios but all i think is overclocking is like an hobby, it requires time, knowledge, and it is not easy to find the best overclocking for your computer if you are not very practic with informatic and especially electronics.
sorry for all those words but i wanted to be clear XD
my specs:
-i5 4670k
-msi z87-g45 gaming(ms 7821)
-kingston KTC 4gb x2 1333 mhz (also if i think they could be boosted till 1600-1800-1866 mhz but im not sure)
-zotac gt 440 2 gb (yes i know, bottleneck of the computer, i wish any one could suggest me the best gtx also used i can upgrade to for 120-140 euro budget)
-1000 w alimentator, but i don't know how to identify it, my uncle assembled my computer for me
-x1 frontal, x2 laterals, x1 backward 12-13 centimeters dissipators case and i don't know how to identify it, it has the 11 number and a X

i think its very important to say, for a mistake i upgraded my bios from 1.0 version to 1.9 version, is it a huge problem for overclocking? will the system be stable anyways?
and, about dissipators on the bios, should i put fan speed up when i overclock the computer? i always did it but i always see fan are not running at an high speed.....i feel confused :eek:
all overclockings i tried were with the turbo boost speed, but with enhanced core boost enabled so the cores are always at the max ratio.
this processor, as you know, at base speed has a 3.4 of base ratio, 3.4 of ring voltage, and 3.8 at turboboost, as base.
i tried from 4.0 (turboboost)4.1-4.2-4.3-4.4
i had the system semi-stable till 4.3 but with high temperatures and i didn't ever know how to set the voltage.
my questions are infinite actually, but ill do only the most important ones:
-Is only-via-turboboost overlock a stable overclock? should i use enhanced core boost? should i use legacy tweaking?
-what ratio could i hit? 4.0?4.4? specificating i want a stable overclocking i think by myself for the few thing i know that 4.2 for my core would be the best, but with which voltage? if needed i could search more info about my case and my alimentator.
-what mode should i use for core voltage mode? auto?adaptive?override? what is the best, and in which cases? should i add some 0.040 in core voltage offset mode? is it useful?damaging?useless? do you suggest it?
-should i change mode also for ring voltage mode? should i change any other voltage when i overlock? what parameters are mostly important in overclocking an i5 4670k?
actually i prefere to stay down to 4.0 - 4.1 with auto voltage and have a non-stress temperature of 33-36 degrees, and 73-75 degrees when stressed very very very much with games or loading, but usually it never goes over 65-68.


im sorry for all this talking, but im really new at this, and i really really like this, it is amazing, funny, entertaining, and satisfacting imho when you get some real results of performance.
thank you all for giving overclocking rookies a chance to learn something in this forum, its amazing.
i wish any one could help me with my doubts, i really really much need help, by ANY one, any one could know more respect me about overclocking on this forum i guess ahah:D
ok i rolled ur balls enough now, time to go bios and to see some more thread about my cpu. thank you all guys

thank you a lot for answering first at all , and then i don't perfectly know what to say, i have x2 cooler on the cpu (air)
and other 4 coolers of 12-13 centimeters on the cause but i don't know how to see where are they manifactured from. the symbol of the case is an X and an 11 number under the X, i didn't mount this computer, and im not very practic with those it(not total pc newbie but, in overclocking im pretty rookie)
would help if i post screen shots of my bios here? i just made screenshots over all the overclocking + cooling section on the bios, saving them on an usb and im trying to add them now i hope that would help you in understanding.

this is the main screen of the overclocking sector, in overclocking should i enable enhanced turbo and legacy tweaking? ehnanced turbo boost all cores to the highest core ratio and LT improve performance in programs like benchmarking i guess.
and this is how my STANDARD bios values appears, i tried all over to modify those value , but mostly with high temp, crashes or instability.
a0kp3t.jpg

this is the under overclocking/digitall power section, only thing i usually change there is the digital compensation, available from 0.9 ,1, 1.1 , to 1.2 page says higher value provide more overclocking abilities and some times i change also the cpu over current protection (i know its UNSAFE) but parameters go from 110% to 200% , i never tried more to 120-130%
and bios totally don't say anything about transient boost, do anybody know what it is?
under voltage and over voltage protections may damage system if they are setted high as millivolt, from 400 to 700 mv are possible.
29xay3d.jpg

VOLTAGES! the most interesting part and the part where i know less atm :((((( how could i set voltages to set processors to 42-43 or 44, could i get a stable system? with which multiplier?
SVID communication is a value that if enable, enables Serial voltages identification, should i enable it?
VCCIN voltage, should i touch it? unsafe?risky?useful? at which voltage?
core mode, core offset, ring mode, ring offset (i think ring is the cache voltage) are to touch? idk honestly
internal voltage ratio protection should be enabled i guess but correct me if i need
and internal voltage ratio efficient management should be enabled? i think yes too but im not sure at any parameter in this page :(
2vcx6bk.jpg

Why the hell is hyper threading on N/A? and the page is also grey i cannot modify :::::::::::::::::((((((((((( i have an haswell i5 4670k and im not using hyperthreading? so suckyyyy
rlgg85.jpg

about this page i know more, i know i should unlock processor maxval, and i know how to set the 4 processor ratio (this page is for in-turboboost processor changes) if you don't touch anything when you buy the processor and mobo, they stay to those values you see in the SS, they came by AUTO AUTO AUTO AUTO, btw. i just wanted to specify by inserting those values. what else could i change in this page?
rlgg85.jpg

very very important: im not sure that via disabling intel-c-state processor skip some halt state that push him down of ratio, cause any time i disabled it the cpu ratio went lower respect how much i setted, i can differently set it from c0 to c1 c2 c3 c4 c5 c6 c7 c7s, is maybe c0 the C state when the processor DONT save energy but goes for performance?
23iaxqe.jpg

this is the fan section, 2 fan for cpu and 3 for the system (one of the system is double and lateral on the case, one is frontal and one backward)
this is how it is standard setted up but i usually move up the minimal speed trying to get more cooler but i don't know why i always see both cpu2 sys1 sys2 sys3 fan stopped in the bios, even if i look into the pc they are working :U
iw0r4z.jpg

is it right if i set minimal to 62.5% or could i even 90? or i should lower, idk
last screenshot, my actual final cooler settings:
2w4aff6.jpg

final setting cpu1=62,5% min 100% max
cpu2=62.5% min 100% max
sys1 80 min 100 max
sys2 80 min 100 max
sys3 80 min 100 max

i specify, my cooling system , my case, and my computer all totally except loud so if it would help for overclocking , i would set fan all to max with no problems.
BUT
as you see in the screenshots, coolers seems not working in bios, while materially they does......T_T
i hope i descripted my bios a little better now

really it is good if i upgraded my bios????? some people told me i risked much but now i can get some advantages, and in reality i got a couple of advantage, in peripherical sector, in audio quality sector, and also in a couple of other stuff i don't get now. but i heard for example that it is not suggested to do modify in the bios OC if OC genie is enable, just can you, spend me 3-4 words on what u think about OC Genie? for my personal experience.... it is not very good and it makes unstable overclocking too, and even not strong too..

First _ maybe your cooler is xigmatek
second - its good that you updated the bios, its always a risk, only the changes are not high that you brake it, and even if you do it like it should you still have warranty.

oke now the tricky part, uninstall all the programs that you use like the 1 for you fans.
make sure that your cpu fan is connected to the right connector on your mobo.
go in the bios and load default settings.
but I miss a image so look for something called adjust cpu ratio and set it to 4.2ghz
then look for something called cpu ratio mode and set that as fixed mode.
leave all other stuff at auto, you don't need to change it till about you go to higher overclock lets say till 4.5ghz
just set the cpu voltage manual to 1.2v and test, Don't use prime95, but test with aida ore intelburn test.
test for about 10 minutes ore in intel burn test on high 10 passes, if your temps are oke then try to lower the voltage, 1 klik, ore go to 4.3
the fans will go higher when the need to.

PS

next time not so much information at ones, step by step please.
its easier to understand exactly what you whant

sorry if i posted that much informations..... but i was really like in a trouble way cause some days ago any overclock i tried out of "in-turboboost-mode" were getting me very high temps.
ill try to cut to say what u don't need: first at all, i opened my computer again but im pretty sure that cpu has only 1 fan phisical. so there is the reason of the things i posted. there is the cpu2 fan chip on the mobo but i watched processor and it look like it has only one fan. do you know how could i identify the productor of my fan?
and i didn't use any program for my fans, just the 1click bios integrated with mobo. i post here the SS i missed in the last answer:
v5v3g3.jpg

my questions are
could i change something else respect what u suggested, now that you see how is the bios page?
voltage: have i to let it set as auto, adaptive, or override, [the mode] after that i tried the voltage you said?
intelburn test: is intel burn test, intel extreme tuning utility? i guess not. ill google this program.
last question, should i use more voltage if i use higher multiplier?
in my first try i have set cpuratio to 43, to fixed mode, and voltage to 1.225, i have 36-40 degrees with cpu idle and 68-72 at load/playing now i will watch the youtube video and search for the stress intel program.

i put here the last settings im using:
cpuratio 44
core voltage 1.285 (computer adjust it automatically to 1.283 since its in auto)
i downloaded intel burn test and it say that after an High Stress 10 steps it's passed and it's stable, but i don't know how to read parameters into the program.
i have actually a idle temperature of 38-40 degrees and soon ill see how it run with games.
p.s. is extreme tuning utility stress tess affidable? greetings

just take it step by step first, set cpu ratio to 4.2ghz and set vcore manual at 1.2v and test, like I say before if good test, then set ratio to 4.3 and test again.
if not good then set vcore a bit higher, you don't need to change anything else only maybe if you are trying to go past 4.5ghz and that's maybe.

as for the fans, if you have 2 fans connected to 1 splitter and put it on the mobo then you see only 1 fan.
if the are all working don't worry to much.

So cpu ratio to 4.2ghz and vcore manual to 1.2v
and no intelburn test is not the same as intel extreme

http://intelburntest.en.lo4d.com/
but set the vcore to manual, otherwise you get to much vcore then you need.

yeah maybe cause i opened pc again and i noticed there is not a second cable to send to the fans.
and elseway i wouldn't have hit 4.5 4.6 even if with stable/unstable situations and high temps, with only 1 fan connected to cpu.
really shouldn't i push up the case fans? wouldn't they help in getting lower the temperature?
but the my important actual question is: how i set vcore to manual? vcore modes are auto, adaptive, override :O

this actually didn't help me, i know how to set voltage manually, but i mean, where i can change the cpu voltage mode (standard is auto) should i use the adaptive voltage or the override voltage settings?
i caugh the occasion to specify, i don't necessary want a super overclock, i want a low/medium overclock with the perfect voltages and low temperatures, if it is possible.
