I could use a few tips on overclocking

[Myrkan]

Hey,

I got an i5 4670k with a gigabyte z87x-d3h mb, corsair cx 600w psu, an evo 212 cooler and 2x8gb corsair vengence lp at 1600mhz

I get a stable oc at 4,2 mhz with 1,23 vcore and 4,1 ring freq with 1,23 ring voltage. The vccin is at 2,0 and and dram is at 1600 mhz xmp profile at 1,6 dram voltage. The temps never go over 75 dc at IETU memory stress test.

I guess I'm pretty unlucky with my cpu, but my questions is if there are any tips or black magic tricks to either lower the vcore or increase the cpu freq or should I just accept the fact that my cpu is rubbish?

Been fine tuning and testing different voltages and freq for a while but I just cant get it stable with any other settings than those i just typed...

Appreciate any answers!

Seems to be abit to hardcore for my taste, looks scary as hell

Don't break it, go slow, lots of stress testing.

@AlwaysFSX

Been fine tuning alot, first tried how far i can lower the vcore without changing anything the auto booster boosted it to 3,7 stable at 1,05v. Goin up from there. 4,6mhz at 1,25 vcore wont even boot and 4,3 is not stable at 1,29 and im not sure if my cooling system can handle more vcore than that.

Is there anything obvious i've done wrong or is there any typical newbie mistake that i've nto listed that could help out. Or is the cpu just rubbish?

Quote instead of mentioning...

If you need more voltage to maintain the speed it means you don't have a magical chip and it can't OC higher than that very well.

You have already played with VCCIN and ring voltage. and your ram isn't at like 2400mhz.

 

You have done what you can on voltages. The only thing left is turning down cache speed to 3500 and trying again.

 

Clock speed > Ring freq (cache). So if you can get 4.3/4.4 with 3.9 or 3.7 or whatever. That will be better than 4.2/4.1.

 

Will that happen? Probably not. You can give it a whirl though. Set Cache to 3500 to eliminate that as an issue and see if you can go higher. As far as cpu voltage you are already at max on a evo 212. So it either can bump up on clock speed at that voltage or it can't.

 

Click just cache in aida 64 to test cache once you have clock done. All these Haswell's are whacky. Mine will do clock speed but not cache. You have one that appears to do pretty good cache but not clock. Haswell has got to be the most fickle chip to overclock ever.

 

Anyways on 4 cores your chip is really a 3.6 chip at turbo if I remember right (the higher turbo is only on one or two cores). So on the bright side if you are stuck at 4.2. That is a 600 mhz overclock in any 4 core application. Cache speed helps a little bit. There are people at 4.2/3.9 cache with dual rad water coolers, so it could have been worse.

Thanks!

Should I set the cache volt back on auto and cache freq on default?

Although im pretty sure it wont go to 4,3 anyways, might give 1,3 vcore a chance but im pretty sceptic. I don't really want the temps to go over 75 in IETU stress tests. But if im lucky I can prob lower my vccin because of lower cache freq to compensate the temp of a higher vcore. Does that sound legit?

Might even try to get the airflow in my chassi to be flawless and hope for som wonders!

Thanks again!

Auto cache will be 3900 on most boards. You have to manually set it to 3500.

Past like 1.25 on a evo is a no no on I5 on intense stuff with all 4 cores going and you really don't want to even get that high on I7 which runs a little hotter rendering. You are pretty much at max  voltage already on that cooler. A dual tower DH-14 can prob go like 1.26-7 on a I5. Dual Rad water 1.3v. Haswell just runs too darn hot.

 

For temps. Run a Asus Real Bench H.264 or a cinebench r15. Those will give you realistic real world maxes (prime/aida are higher then you will ever see). If the spike is near mid 70's. Too high imo. Especially with summer coming where it is going to be even hotter. 4.5ghz won't be my summer overclock. I will go down to 1.150 volts and 4.3. 4.4 on mine is almost the same voltage at 4.5 (Haswell makes no freakin sense).

 

Also yes. Lower VCCIN will lower temps a lil. There is the VCCIN guide. Keep within .04-.06 of Vcore or Asus says you can damage the chip.

Basically Haswell is a pain in the butt to dial in sometimes. Then you have wrong guides telling you that cache matters a lot (it doesn't). If you get 4.3 I think that isn't bad to be honest. 4.2 is bearable. Below that is kind of depressing, but it can happen on the very best Z87  you can buy with dual rad water cooling. That is just Haswell . 

 

If you get 4.2 on a Evo 212? Just remember you paid a lot less than someone who is at 4.0/4.1 on water and a ROG board. Take the safe temps and don't get greedy.

Cool, as I said my evo keeps my i5 on 75dc, never warmer exept from running intelburn (very high mode) then the temp is constant 90dc so turned it off after 4 tests...
