I have finished the build

it's messy and a cable nightmare until I tidy up but I wanted to test the water cooling setup

so far all good, idle temps just break 30

ran Unigene valley for 10 minutes, got up to 55

downloaded PRime95 and Aida64

and here's where it gets screwy

they BOTH instantly shutdown the PC .. and I mean .. the instant I click start the machine powers down and restarts!

this is not normal.

Halp ?
 
intel i7 4790k
Gigabyte Z97x-UD5-BK

apogee HD Block
Dual bay D5 res
xspc 360 rad with 3 x GT 1450 rpm fans

16GB Kingstom hyperX Beast (XMP Profile 1)
160GB Intel SSD

GTX 780 Windforce 3GB

corsair HX1000W psu

just Ran Arma3 for 10 minutes on bechmark mission and it was fine ... load temps 55-60
(some cores ran hotter according to Core Temp)
 
It will be hitting the tj max for temps. P95 AVX and extremely high temps on haswell are the norm. Theese chips aren't designed to run such stress programs. Unlike other Intel chips that have a soldered heat spreader theese use poor quality thermal paste that is badly applied on a lot of chips. Not even high end water cooling helps. Hence why you see many users delid theese chips and replace the paste.
 
latest bios might help you,they run at a high cpu voltage with shipped bios far as im aware,latest bios reduces it and temps

around the 1.2v mark at stock is the norm

that quick ? I expected some overhead but it doesn't even make the first calculation..

My mouse doesn't get chance to "click" before the PC just dies. :confused:

aaaah I've not been into BIOS yet other than to set XMP.

I'll have a look at volts.. thanks
 
Holy crap.

maybe if I ACTUALLY LOOKED at core temp ...

over 1.4v and somehow it's auto clocked up to 4.5 ?
 
As wazza says, latest bios will help. But maybe not an awful lot. My one in sig hits 94c in p95 in 2 seconds, vcore of 1.200. My previous one was the same. Theese are no cooler than the older 4770k no matter what Intel say.
 
cheers gents

I'm a get some sleep and flash BIOS with a clear head tomorrow.

in good news, Gaming on this rig looks silky smooth ! ... so much better than me old phenom .. sooooo much better ! :D
 
Yep, in normal use they run cool enough, even when oc'd. You just need to avoid running any stress test that uses AVX instructions. A good stability test is Asus real bench.
 
1.4 at 4.5 is fine, mine was on that for over a month.... it only dropped to 1.334 yesterday at 4.6.............your idle core temps are ok too
 
Yea that is too high a voltage for sure. I am running at 4.7ghz at 1.265v for 24/7 use if that helps.
 
On asus boards, the first beta bios for Z87 (ver 1504) had a higher stock voltage and a 4400 cache/uncore clock. The full release 1505 bios dropped vcore a good bit, and also lowered cache to 4000.
