Hello,

Just finished building my rig a 4930K with asus ramp. IV Formula. Corsair dom. plat. 2133.

My CPU seem to be crap since it needs 1.45V @ 4.5Ghz and still crashes in prime test. At 3.9 turbo mode it need 1.32 to run stable.

This one is for certain going back either to store or via intel tuning plan.
Tried all sorts of settings in bios and it is impossible to run at a reasonable volt at 4.5Ghz.

That is of course if I have'nt missed anything in the settings. Perhaps the experts at oc.uk have any advise.

Hello

Thanks for the input.

1.I set my ram to xmp and bios then sets the settings for the ram at the exact spec they are designed for.
Setting the ram at 1333 results in more stable prime95 but still generates errors after 30min. Also memtest gives errors.

2. Setting 45 ratio on cpu in bios gives around 1.4 in windows cpuz. I have tried increasig the volts in bios to what has been recommended by many guides in the internet but absolutely nothing helps. Today I have headache because of 4 late nights this week trying to get the cpu under reasonable volts. Without success:mad: But I am still happy :D. Volts go up when prime95 is running if i dont set LLC to 0.

So I have tried to follow many examples on both the asus rog site and other overclock guides but nothing works.

Its probably just a crappy chip. Going to try and get it back to store tommorrow but I dont think I will get a new one since it is running ok at stock.

I have bought a tuning plan from intel. So is it just to wait out the 30 days and then send the cpu to intel HQ in USA? Or can I bring it back to the store where it was bought?

Hello,

Yeah. I have set voltage manually. Need to be around 1.42 to boot windows. Then I have tried all LLC settings. And if I set it high the volts are adjusted upwards when prime runs. If I set to regular(0) then I need to add more volt because it is not selfadjusted.
 
Hello

VTT tried both 1.1 / 1.2 no difference.
CPU at stock = No problem booting with xmp memory 2133 CL 9 1.5V. No problem running HCI memtest. As soon as I juice up my cpu issues start.
I cant keep a reasonable volt below 1.45 at 4.5 GHZ without crashing in memtest and prime95. Even if i set high volt like 1.5+ it gives error but not immediately.

So with that i think the cpu needs to much volt and is a crappy monday build :)
 
Update: Just running prime now turbo mode: CPUZ reports 1.344 Volt. Temps are around 65C

This is with auto setting V-core in bios. Cant lower it then prime reports errors.
LLC is high. Otherwise default settings all else.

Board is ASUS rampage iv formula

This must be wrong???
 
OK guys, I was just in a chat with a Tech support at intel and I nearly fell off my chair when I read what he had to say about my CPU. So here please have a laugh :)

Chat InformationPlease wait for a site operator to respond.
Chat InformationYou are now chatting with 'Alberto'
Alberto: Hello. Thank you for using the Intel Customer Chat Support service. We are glad to be of service. How may I help you?
Anders: Hello
Alberto: Hi
Anders: I just built my system: i7 4930K processor and it requires abnormal high voltage
Alberto: I'll be more than glad to assist you with that
Alberto: What kind of motherboard do you have?
Anders: Asus rampage iv formula
Alberto: What is the wattage of your power supply?
Anders: it is 1200W
Alberto: I see
Alberto: If you use one lower than that one
Alberto: It will not work?
Anders: Hmm. Have not tried that. I only have this one
Alberto: Ok, normally the wattage on the power supply could be 500 600
Anders: for sure it will work but I want to run my PSU at around 50% to get low temps and noise
Alberto: depending on the components
Alberto: I see
Alberto: The processor will take the voltage that he needs from the power supply
Alberto: *it
Alberto: to work properly
Anders: yes, but does the W of the PSU really afffect how much the V the CPU uses?
Alberto: No, it shouldn't
Alberto: But what is the voltage that is taking?
Anders: ok. my problem is then that this particular cpu I bought last week requires 1.344 V when running in windows
Alberto: The voltage for the processor should be 1.5V
Alberto: Ok, that is good actually
Alberto: normal
Anders: good?!?
Alberto: normal
Anders: hmm Due to the high V it needs for stock speed turbo there is no room for further overclock.
Alberto: I see
Alberto: Ok, the voltage fluctuates, it should be 1.5
Alberto: but it could be a little bit higher or lower than that
Alberto: like 1.3 1.4 1.6
Alberto: low
Alberto: If you are doing overcloking
Alberto: That will be different
Anders: so you mean 1.6 is safe for the 4930K?
Alberto: Since we don't support overcloking
Alberto: Not safe, but when you do overcloking
Alberto: It might reach that
Alberto: And since this processor is unlocked
Alberto: it might work
Anders: ok, i bought a intel tuning plan to replace the cpu. Do i just wait the 30 Days and send it to intel HQ in USA?
Alberto: Yes, that is always an option for you
 
Well, yesterday i brought the cpu back to store. They have a 20% return policy if package is opened. So i will get 80% back from what i paid.
Also bought another 4930k. And lets hope as you say that I cant be that unlucky twice.

Gonna test it tomorrow.

Ok guys. Good news. Installed new cpu today and hurray this one is much better. Running prime errorfree as we speek at 1.3V @4.5 ghz. Will try and lower v later see how low the cpu goes.
The previous cpu was running 1.3V at stock 3.4gz.
