Mine are hot - not the best day to be stress testing your new CPU :p

What's the starting point for an i7 3770k for setting vcore at?

Currently on 1.272 (which is a figure I picked from my bum) which vdroops up to 1.296 under load with it set to 'Extreme'.

Running at 4.5 Ghz.
 
Can anyone confirm whether these temps are ok for a stock 3570k at idle (bios):

Core 1: 45c
Core 2: 43c
Core 3: 37c
Core 4: 36c

Am using a Gelid Tranquillo. Basically a bit worried about the core variation and high values in the bios. I used Arctic Silver 5, and the build was done today. Cheers!
 
Well I've come to the conclusion that my 3770K is an absolute dog... can't seem to get it stable unless I put silly volts through it, which I'm not willing to do. Mind you at stock it's still a cracking piece of kit!

Might be that motherboard needing a new bios i know 1 came out for the formula
which helped stability
 
Can someone help me here, I've been having crashes and suspect it's down to my igpu

I've got it set to disabled here 'internal graphics'

http://www.coolaler.com.tw/coolalercbb/ivybridge/GA_Z77_D3H/13.png

But when i raise the voltage or clocks the temps change, even when it's disabled. I did this because I intitally had the volts and clocks set to min and since I disabled it in the pic above I put volts anc clocks back to normal and the temps went back up so I suspect more volts are going through it, even though I disabled it. Is it possible to stop volts going through it completely?

I only did this because when volts are low I suspect it causes my crashes, though if I put the clocks to normal my temps go up by 10c :(

But it is enabled and set to auto, or am I missing something here...?
 
...ah now I understand.

I have mine set to disabled but I'm not sure if I would wish to touch the volts going to it - even though they seem, for you, to increase over and above what is set at when enabled.. I can appreciate that by lowering the volts manually you can reduce the temps but are your temps that bad that you need to be doing this and compromise your stability, it seems..?

By just disabling the iGPU and leaving the volts and clocks alone what temps are you getting and with what vcore and overclock...?

it's going over 80c with 1.240vcore 4.5Ghz with stock igpu settings, when i lower the volts on the igpu to their min that the bios will allow temps drop to 70c under max load. But I'm getting instabilities I believe when undervolting this way. I thought disabling the igpu would mean it would not be in use, but instabilities mean it's being used in some way?
 
Since you probably will know that the TJ Max is 105c you are still a bit of the CPU throttling itself and I imagine that the temp you quoted is when stress testing and not when playing games etc. Also it is quite warm etc generally at the moment.
Not sure about your cooling solutions or if you decided to flip the lid on the chip etc but maybe someone else better informed can answer your specific questions about the iGPU..? I assumed that whilst it can be disabled within the BIOS, so that the system and OS are not aware of it, the voltage side needs to be left at the minimum of what is needed for stability and from what you have shown it would tend to suggest that is correct..?

TBF a great many settings of what is available in my UD5H BIOS goes woosh over my head but as long as my 3570k is stable and using 1.212v at 4.4Ghz I'm happy enough. My temps can get to a max of upto 80c when stress testing.
 
Just tried 4.5 using 1.296v and prime on blend. After 6 minutes one of the workers stopped with a rounding error but the others kept going and no bsod. Should I add more vcore or VTT?
 
My chip is definately not the golden chip. 1.365v for 4.6GHz and it still fails prime within 5 mins. I have upped the VVT frm 0.750 to 0.875. Enabled PLL overvolting. Gutted. :(
 
Don't know why you just don't go for 4.4..? I assume that you got the 3770k for its hyperthreading capability so just clock it to 4.4 and enjoy using it. You also have 16gb of ram so you must be running something regular enough with high memory requirements. The performance difference is negligible and you will not be on the edge of stability.
Then again just noticing the volts on your less than stable 4.5 and you might end up with 4.3 at a reasonable vcore.

Ive been messing with my 3770k For nearly a week now, im glad i made the switch from AMD to Intel. :p

Ive got it at 4.5Ghz (stable) with 1.250 vcore and getting max temps of 84c with a H50-1. Idles around 30c-33c

not bad for a low end all in one cooler that's getting a bit old :D

Just need to sort out some custom water cooling so i can push it further.
