***Intel i7 4790K Owners thread***

If thats without delidding at about stock 1.2v thats a very good temp yeah. Dunno why your temps are jumping around, from the thermal past not been spread properly i normally find one or 2 cores is a lot hotter than the others, rather than jumping temps.

It's not so bad now, the temps are only jumping around 2-3 degrees but as of currently with a 1080p Twitch stream and a few other tabs I have 24 degrees on the first core, 25-27 on the second, 24-26 on the third, 23-26 on the fourth, and 26-30 on the package. They are sometimes jumping up to around 35 though for about half a second, not sure why though?
 
Its just something loading in teh background causing it to do that dont worry about it. A few degrees difference is normal in teh core temps, its when ya start getting 10 degrees+ ya know ya need to spread your thermal paste better or check it for contaminates.
 
Got it to around 4.7 now @1.285 voltage, how far should I go with this thing?! Still only a max of 60 degrees under RealBench.
 
Those friends shouldn't be building their own PC's, if they are unable to do it properly (reading the manual, updating Bios etc). It's not exactly rocket science to read a manual, or to simply know to update the bios on a new motherboard for maximum performance/bug fixes.

I'm sorry, but I don't agree. To my knowledge there is no cpu that will physically fit in a H87, Z87, H97 or Z97 board that requires 1.4v at stock settings.

I'm not sure it is that great an idea to have to flash bios while the chip is running way hot under the perfectly valid (for stock settings) boxed cooler.
 
Just got BSOD at 1.3 with a 4.8 overclock, had the frequency set to 4.9 in BIOS. What next?
(The BSOD was made through stressing with RealBench) Although I think it might have been something to do with the display adapter, since the cable I'm using is being a little bit funky at the moment?
Temps are still between 27-30 idle and 60-65 during RealBench

No that sounds about right, i get BSOD on 1.3v trying to get 4.9ghz mine requires about 1.33 to get bench stable. It used to take about 1.35 to get bench stable so its coming down over time.

So is it alright to try and push 4.9 with 1.35v? I saw a max temperature of 65-70 although this was doing a stress test, and surely in a realistic environment I'm never going to be stressing the processor that much to get those kinds of temps?
 
yeah sounds bang on, if your getting 70 under stress test youll prolly only get about 50 in real use.
 
If your using a loop cooling your GPUs too dont forget to add them on too, whne i play constant games it can heat my loop up by 10 degrees, which pushes the CPU temp up by around the same amount. If your GPUs are air cooled then your all good.
 
No GPUs in the loop yet, that comes later! Just fiddled around a bit more and it's starting to struggle getting any higher clocks now - 4.813ghz is the highest I've seen it got at 1.349v, not sure if I want to risk going any higher at this point though. Gonna fire up a game in a bit and see how it heats up in a realistic scenario.
 
Seems to be constantly sat at 4.66ghz now and pushes up to around 4.75 sometimes. Multiplier is 49 and voltage is still 1.349v. This is fun, I want to see how much I can get out of it but I don't really know how much voltage is too much - only just got the chip so don't want to bugger it.

CPU-Z only showing as 1.349 but CoreTemp showing 1.352, bit strange but nonetheless the latter is what it's at. Now just to keep stressing it for a few hours and see how it goes!

Has anyone got over 5ghz on these without 1.4+ volts? I thought these were suppose to get 5 ghz on air cooling, but i wouldnt fancy running over 1.4v on air.
well not rly. there may be some extra gooooood chips but its like 1:1000000 :D
My chips is rly good but still needs 1.41-1.42v to be stable at 5G.
This is with delid, no IHS(direct die cooling), CLL Pro and temps at about 60C in real bench H264. I'll be adding my Mora3 420 to the loop soon so it may help a bit :)
For 4.9k it only needs 1.29v tho which is rather impressive.

Still waiting for fans and hoses :(
 
Managed to get her to 4.95ghz at 1.365v I think it was, posted but crashed almost immediately when starting RealBench unfortunately!
 
yeah if it crashes as soon as you start a bench program its prolly gonna need another 0.03v i find to get it completely stable.

Im guessing your gonna settle at 4.9 for everyday use, but your just seeing how high you can get it?

Probably just going to settle at 4.8 to be honest, need more voltage to get to 4.9 and I'm already at 1.358 or something.
 
Just got a 4790k, not had much time to pay around but 4.7ghz (1.19v) with ram at 2200 took all of 20 seconds. Think 4.8/4.9 should be doable for 24/7.
 
Passed 32m super pi at 1.2v (6:28), obviously fell over with prime but the chip seems to have potential. Hopefully have a good play tonight.

Think having a PA140.3 just for the cpu helps somewhat.
