So I got to 44 but on insane voltage (i7 4770k)

post #1 of 6
Thread Starter 
I was able to get to a stable 44 on 1.37 volts but I brought it down to 43 with 1.3 just for chip longevity and turned on adaptive mode with a 1.3 turbo.

I've heard that since the vrms are on the CPU buying a higher end board would do very little in terms of oc ability. I currently use the z87-k which is pretty much the cheapest asus mobo out there.

I'm pretty sure I lost the silicon lottery but would getting a higher end mobo give me more oc ability? I've heard rumors that some of the budget boards were somehow nerfed by intel to weaken their oc ability. This could be just be. What do u veterans think?

Did you increase input voltage vrin/vccin 1.9-2.0v try those values and report back try the following...

44x 1.34v

uncore 41x 1.21v

input voltage vrin/vccin 1.95v

good luck thumb.gif

Wow made a huge difference. Thanks!!!! 44 on 1.36 but seems much more stable.

Should I keep the voltage at static 1.36 or try to use adaptive mode now?

Defiantly try adaptive no need to have it running static all the time you can even try 2.0v vccin and see if you can lower vcore some. also update your bios if u haven't already. I have seen some bios updates increase stability on haswells esp uncore part. Good luck thumb.gif

Is there any danger in putting your vcin at 2?
post #6 of 6
No just increased heat some chips require more vccin..ive notice usually the worst the chip the higher input voltage needed ultimately to be stable usually not much more than 2.0v is needed up to 2.1-2.2v can be ran 24/7 but I personally wouldn't go above 2.1v for 24/7

to give u an idea 1.95v vrin to 2.0v vrin is about 3-4c difference in temps overall.
