post your i5 4690k/4670k overclocks

[Tiwaz]

Hey guys,

I was just curious what overclocks you got on your i5 4690k or i5 4670k. I would appreciate iit if you post them here with the Voltage and what cooler you have. I currently have 4,6ghz on 1,255V on the 4690k w/ NZXT X61 and I will be trying to get to 4,7ghz. I hope its okay if it reaches the high 60's°C

thank you very much!

it'd be ok if the temps went 85°. to most that's too high, but 75° wouldn't be a problem.

[79wjd]

4670k - 4.2ghz

4690k - 4.5ghz

Both are around 1.25 iirc.

lmao i just did 4,7 on 1.290V i will see if thats stable, really takes some  time. IBT or Prime95 are just gonna kill your cpu tbh, AIDA64 or doing rendering as a stress test better

you should be able to keep them stable at 1,225V

Prime 95 isn't going to kill anything as long as you have a set voltage.

it easily gets your cpu above 80°C while AIDA64 or rendering 4k video is like 65°C if you do it longer

using p95 properly can wart off stability issues:

80ºc is perfectly fine even for extended periods of time. Yes, Prime 95 will push your CPU harder than most realistic workloads, but it's not going to kill anything. I stress test with Prime 95 and set my target goal max temp at 90ºc -- that usually equates to a reasonable 70ºc~ in most reasonable workloads (and no, 90ºc during a 24 hour stress test run isn't going to do any damage either).

my 4690k was stable at 4.8ghz 1.28v, 4.6 was stable at 1.23v.

 

4790k 4.8ghz at 1.3v.

anything above 80°C is bad on the long run

Not it's not, and again, you don't run Prime 95 in the long run.

4690k stable at 4.4ghz, 1.25v - around 65C under load with a Dark rock 3

 

(I could probably drop the voltage, or increase the frequency, but havent had the time to experiment further....)

mine did 4,6 on your voltage, go a bit higher

Just because yours did doesn't mean someone else's will.

My 4670K must have come from the rubbish bin. barely muster 4ghz, 4.2 if I border unsafe voltages. 

 

Temp wise I'll get back to you for figures, they are meh on a full custom.

usually all decent intel cpus do +200mhz offset without voltage increase and when you can do +300 or +400 without it then you have an above average sample

To be honest, I think the cause of poor OC isn't the chip being poorly binned, but my mobo. A VRM heat sink is basically falling off which probably isn't helping matters haha.

i have the cheapest Z97 mobo with sli and vrm heatsinks i could find, so its not that. And hte mobo is complete garbage, only two of hte S-ATA ports work and some other guy online wrote that the m.2 doesnt work as well

Not every chip overclocks the same. Just because you get certain results at a certain voltage does not mean other people will reach those

OP, please understand that OCs can often come down to who won the silicon lottery. If my chip has better quality sillicon in it, it will outperform the same chip with worse quality sillicon.

Hmm, iirc proper cooled VRM's are quite important in overclocking, for stability and stuff, so it could be the cause. Even a rubbish heatsink will be better than one half hanging off.

turns out my i5 is garbage, i can do 4,7ghz stable on 1,260V, but i cant even be stable 4,8ghz 1,310V

That's not garbage by any means.....Most Haswell CPUs struggle to get past 4.5ghz and even that's not easy to achieve.

You missed the /s. For a moment I thought you were actually being serious. 

[Heavygun1450]

So far, my I5-4670k is at 4.3GHZ at 1.270v with a hyper 212 evo, with a max temp of 75C.
