Temps too high for me your reaching into the 90's there , but an amazing result nevertheless as many see temp into 90's at stock.

Personally it seems a excellent chip, well done matey :D 1.5V though scary

Yes the 1.5v was for about 20 seconds just for screenshot, the initial boot volatge that Asus put on for Auto is around 1.7v again just for booting, mine was into windows then I just turned the power off after screenshot 1.5v is too much for me also.

I might be selling this CPU and try a different model almost had my fun with this one now.

My stock 4790k runs extremely hot during the small FFTs test in p95. Power jumps to around 150/160W and temps go over 90 :(

I'm using a noctua u14s cooler with just the one fan and I am pretty sure it is seated correctly. I have taken it off just to check the spread of the themal compound and everything seems fine there.

During standard gaming (dota2/watchdogs) it doesn't go above 65.

Am I missing something obvious here?

Those temperatures are atrocious. Mine at 4.8GHz reaches around 90C in IBT.
 
Got another DC i7 4790k here that have been trying to OC on a Gigabyte gaming 7 board and it just isn't playing ball.

It is cooled with h105 and corsair SP fans all on max (so loud as a helicopter taking off)

Further to that this chip seems to suck. I can't get it stable at 4.6GHz @ even with 1.35v. It all seems fine but then it overheats as it shoots up 100 degree while gaming after 10mins.

If I drop the volts at all it blue screens in about 30 seconds.

Have tried to re-seat the cooler 4 or 5 times with Artic Cooling MX-4.

Assuming this is just a bad chip?
 
I'm now in this club but I chose the chip at stock instead of 4690k and cooler so will be running stock for a while.

Is there any way to do a quick and dirty yet safe overclock to see what I could do 24/7 with a decent cooler.

Cheers.

46x 1.25V see if it boots at least but first what is your stock voltage at default frequency?
 
Ok managed to get up to 4.9GHz @ 1.35v which is stable gaming. Max temp around 70 degree after 90mins. Only runs Prime 95 for about 10 mins before it peaks at 100 degrees and shuts down though.

That is on 4 core - 8 threads also.

Also with that I have 16GB (2x8GB) RAM on 2400MHz with 11-11-11-30-T1 timings. So looking a little better and if I could get some better cooling than the H105 with the SP fans then the magic 5.0GHz might actually be achievable for gaming at least.

Crysis 3 on max settings apart from AA which is on FXAA runs at 32-38fps @ 4k. No noticable micro stutter or tearing. Which is pretty much the same as the 780Ti's in sli have been achieving.

Metro: Last Light gets around 25-30fps @ 4k and feels reasonably smooth actually.

However this is only the same as a single 780Ti is achieving so quite a big difference between Metro: Last Light & Crysis 3. Everyone used to say that Crysis was not optimised but based on the results I would say they have done a pretty good job.

Things have been better since the latest Nvidia driver and also updating Bios to F6.
