hello,

So i decided today it was time to give my I5-4670K a little overclock

my system;
i5 4670K
hyper 212 EVO
arctic silver 5 thermal paste
gigabyte z87x-d3h
2 * seagate 750 Gb RAID 0
6 Gb kingston RAM
CX750W
saphire radeon hd 7870 ghz edition
corrsair 750D
ambient room temp= 21 C°
the pc in an open space next to me.

first i stress tested the CPU at stock settings and it get 60 C° and it got 65 C° when stressing my gpu at the same time.

next i update my motherboards bios, witch went well and my bios version is now F8

i looked up some OC's other people got and they said i should be able to get 4.6Ghz @ 1.22V

so i put 4.6 as clock and 1.23Vcore
it instantly BSOD on windows start up

i kept stepping down until i got this

my Vcore: 1.23V
my highest (stable??) clock: 4.3 Ghz with a turbo on one core 4.5 Ghz

when i ran prime95 (small FFT's) it instantly jumped to 92 C° with a max of 100 C° i immediately stopt the test

i also idle at 35 C°

i'm going to set it to stock clocks until i know what the problem is.

how can it get so high while with other people sit around the high 60's???

tools i used:
cpuZ
HWmonitor
prime95

i was thinking it might be bad appliance of the thermal paste.
i used the pea method but while mounting the cooler i did something wrong so i wiped of most of the thermal past with some paper and re-applied some thermal paste.

any suggestions?

thanks in advance ;)

Well you are using a 212 and the 4670K isn't the best overclocker you know? I'm using an H100i and my CPU tops out at 4.2GHz @ 1.224V max without getting unstable. The best advice I can give you is to make sure your cooler is mounted properly. Although to me it just seems like the 212 couldn't such an extremely high clock seeing as how the package was running at 99°C which really speaks to me as an inadequate cooling solution.

As you probably might already know, every CPU is different.

I do know a lot of people with a 212 but I can't think of anyone off the top of my head that uses it alongside a 4670K. And what results do you mean? My CPU currently runs at 4GHz because it wasn't a very good overclocker at all.

You could try this guide and my vcore is stable at 1.2670V with no offset of any kind using the MSI command center software to do the OC instead of the BIOS. Just plain fixed voltage mode is the recommended way to go with any overclock. Disable turbocore and any other auto-overclocking features such as OC genie.

Also on load I'm around 60C when I go up to around 4.3GHz. I always thought that the average for Haswell on a 212 (excluding devil's canyon) was 80C on load? Which is still somewhat safe but its definitely on the edge. I choose to leave mine at a constant 4GHz as my H100i can effectively cool it on the minimum fan speed (around 800RPM with Corsair SP120 Quiet Edition Fans (PWM) ) under full load without going past 65C and stay in the low 30's on idle.That way I'll have an effective clockspeed while maintaining a decent noise/performance ratio. Although if I had known I was planning to do such a thing I would have gotten a PH_14TCPE or maybe now a Cryorig R1 Universal.

i'm going to try the guide tomorrow, if i still get the high temps i'm going to try to redo the thermal paste.

if i get high temps then i will just settle with a very low OC.

thanks for your help man
