4770k dead or MSI Z87-G45 dead? - Page 4

post #31 of 58
What would worry me is VRM control is on the chip for Haswell, do not know what the VRM are like on the G45 board, but I suspect you were pushing the VRMs and the controller.

Yeah I'll check it out. I come from AMD and everything is different. My 8350 had a max temp of 60c for prime95, anything into 70's was bad. So for that chip heat came into play far earlier than over voltage :-/

I actually did full oil submersion with that system at one point. A heat exchanger ran outside and cooled the oil to 0c in some pretty chilly Wisconsin weather.

So what would you guys stability test with now that I'll probably never run prime ever again?

Whilst 1.5v is excessive for a cpu, especially haswell on a 4.7Ghz overclock I dont think the cpu nor motherboard is dead.

My power supply died a while back and it did this exact same thing, power on for a second then shut straight off. What power supply do you have mrkubanftw? Can you test it outside of your case?

I would not advise you jump to the conclusion most people are saying here in calling your cpu dead, just because you ran it at 1.5v. Heck ive ran my 3770k at over 1.6v before on air and its not dead.

I checked the psu and she fires fine jumped with no load. It's a cooler master gold pro 1000w. I think that would take it. It ran my fx8350(much higher tdp) and 3 7950's in a bitcoin rig.

The only think that makes me think it's the board is the aforementioned symptom. A short in a processor is a short, there are no capacitors. It's transistors and resistors. Wouldn't the system just not turn on at all with a short? We have the system powering on, charging the capacitors and vrms, and then it fails. Those symptoms are the only reason I'm still on the fence. In my experience a bad processor won't even allow the board to power.

I see, well maybe its the motherboard then. I highly doubt its the cpu unless you put too much TIM on or something and it spilt over and made contact with those small resistors on the actual die somehow.

Out of interest why on earth did you run 1.5v? Did someone recommend that voltage to you?

Edit: a system powering on and off is usually symptom of a short your right, to check this just run the pc outside of the case, use the motherboard box to stand it all on. I think your pc will run with a dead cpu, it just wont get past bios splash screen.

Lol yeah check some of the earlier posts in this thread. There was a post on these forums (one of the first hits on google unfortunately) that were saying 1.5 was alright with temp control.

Ahh I see. Well this system did run for 2 weeks at base clock. So I don't think it's a case short issue. For the slip second it powers on I don't get even close to the splash screen. Monitor doesn't even have a chance.

I would still take out the whole of your components and run then on a motherboard box, ive had my pc start shorting at the most annoying times.
