Hello and thanks for reply . Yeah i think it is same with me but problem is they say they could't notice any noise so even i still have warranty they won't change motherboard so i guess i will have to buy soundcard and give it a try if i don't find any other soulution..

I am still looking for solution. Someone please?

Well Turbo should boost multiplier to 42 when it's needed. As far as i know base clock can't change like that on its own. Now it is just a bit higher, also same with voltage. I am afraid what if sometime it goes too far on it's own like that and cause damage. Is that possible? I run test few more times and it's ok now, it looks like it is not happening anymore

I have i5-4670k, asus z97-a, Patriot Viper 3 Black Mamba 1600Mhz. XMP profile is turned on base clock is 100 multiplier 42 with sync all cores core voltage adaptive cpu core voltage offset 0.001 aditinal turbo mode cpu core voltage 1.145 Everything else is on default settings. I got this while running cinebench r11.5, it is just a peak but still this is not what i set in bios. Should i be worried?

I doesn't matter it is same both ways. It looks like noise is louder with reltek drivers than with windows generic sound drivers, it's weird so i might be wrong

I am sorry English is not my native language. When i connect my headphones there is loud static noise. I bought my PC and Headphones in two different shops. First i sent my PC to... (i don't how is it called) back to shop so they can check if everything is ok. They told me that everything is ok with PC, they couldn't notice any noise with their headphones. Then i sent my headphones to shop where i bought it. They sent me new pair of headphones. I plug them in and there is static noise, same like on the old ones. I called them and guy told me, there wasn't any problems with old headphones but he sent me new headphones just to be sure. Now i am back at the beginning and i don't know what to do. http://www.asus.com/Motherboards/Z97A/overview/ http://www.razerzone.com/gaming-audio/razer-electra I don't have splitter and i am using cable without mic.

@Faceman Yes, there is such option. Thank you very much. I read some post on tomshardware and guy says that is better to set offset voltage not to auto but the lowest possible, how is yours, is it on auto? @deviant88 Delid? I don't want to rip off upper half of my brand new CPU... so as Faceman says it is last resort. I run both, IBT for 10min the highest temperature was 87C, prime95 for 30min the highest temperature was 83C. While gaming it is much lower but i will monitor temperature for some time just to be sure.

That is amazing. First guide it says stress test for minimum 8 hours. Do i really need to put that much stress on my CPU? There is no game that can stress CPU that much... IBT x20 times on high sounds reasonable to me, am i right? It also says temps should Not Exceed 85c-90c maximum, so that one core with 87C during stress test is acceptable right? I think there is no point going for higher clock since i have pretty high temperatures with this one... Update: I left my CPU on 4.2GHz @ 1.15v my system crashed so this time i downloaded prime95 set vcore to manual and did stress test for 30min. no crash, temperature was lower them with IBT, 83C iwth prime95, i set vcore to adaptive and started skyrim, system crashed again after couple of minutes... I tried to run games with manual vcore and no craches In bios it says CPU voltage 1.008 which is default voltage not the one i set. It looks like when i set voltage to adaptive it reset cpu voltage to default. That is not what adaptive should do right? How to fix this?

wait... Vcore is core voltage? It is 1.149v(1.15), not 1.5V... sorry typing mistake... look at the screenshot

Hi Guys, i want to overclock my cpu, i found guide, updated my bios, set multiplier to 44, vcore to 1.25v, input voltage to 1.9v, and during stress test one of my cores hit 100C so i stopped test immediately and loaded default bios settings. This time i changed cpu multiplier to 42 and vcore to manual 1.15v (i also tried lower vcore but this looked like the most stable one), everything else on default (auto) settings, after i finished stress test i changed vcore to adaptive. This is what i got: As you can see i run IBT on high x20 times, this is hopefully stable enough for daily use and gaming. This is only peak temperature and games should not put this much stress on cpu, so temperature while playing games should be lower, right? Is this temperature going to have impact on my CPU life? Should i now try to change cache ratio, cashe voltage, input voltage or leave it to auto? Why such a difference between core temps, i got bad chip or what?

Thanks Yup, i absolutely have to, i can't reach back panel, cable is too short. It is right port, it should be enabled in bios i checked Edit: If anyone ever finds this thread, here is solution: Unplug headphones Uninstall realtek drivers Reboot Connect headphones or speakers at front panel Let windows install generic sound drivers Now computer should detect headphones/speakers Install realtek drivers, this time realtek drivers will detect front panel

Do you mean in playback devices? There is no front audio option OS is windows 8.1 if it means something...

Motherboard is ASUS Z97-A, case is arc midi r2, on cable it says HD AUDIO and it is connected to front panel audio connector 10-1 pin AAFP, the latest audio drivers from motherboard support page are installed. When i connect headphones they are not getting detected, there is no sound. Please someone help me.
