4790k died

pete910 · 4 Nov 2014 at 09:42

Well after yesterday evening of trying to work out why the computer stop working , it's turned out to be a dead cpu :eek:

Over heated while playing Arena commander on me the night before which I thought was strange . Especially since its WC 'd and de-lided . Went to to turn on yesterday and its a no go . Done all the checks , only other component I can't check is MB .

Board is showing CPU failure so pretty sure it is cpu anyhow.

Not a happy chappy

Well lesson learned (the hard way ) . Don't mess/mod something till warranty has expired :rolleyes:

What sort of voltage were you putting through it, and what sort of temps were you getting. I'm assuming you delidded a while back and it ran ok after this?

Yea, was a while back .
Just shy of 1.3 @ 4.6. Temps have been in the 70s when getting a lot of stick, mid 60s playing games

Been fine for a good while till now . Think maybe playing Arena commander and recording it just tipped it maybe . Thinking about it , recording game play would have hammered it quite hard I suspect .

1.30 and 4.60 even with hammering should not of killed it, Probably just a defective chip.

70's us pretty ok, similair here in games with 1.300 @4.7, though not delidded. No other chip you can test to ensure its not the board.

If its under warranty, just RMA it!

More than likely, downs side to modding. Warrenty goes out the window , Just pulled the trigger on another. WONT be deliding this one. will wait till warenty expires.

Never mind, might have some Haribo though tommorow !!!!! .

Delidding invalidates warranty unfortunately.

Edit: Rats, pete just said that! Too slow :/

No i dont, MB is showing CPU error.

Other than the person referred to in that post did anyone else receive a refund for a dead de-lidded cpu?

los · 4 Nov 2014 at 12:29

Got to be worth contacting them, nothing to lose hey.
Providing it definetly is the CPU at fault

I'm not sure, just thought it might be worth pursuing.

i dont rly think 1.3v would have killed it... especially on W/C. It must have been something else

Dave2150 · 4 Nov 2014 at 21:46

Delidding is always risky, too much pressure on the die can kill it instantly, or over time, if not done perfectly.

Can you elaborate on this, please. Are you referring to a cooler plate being directly against the die solely or can this happen with the stock heatsink as well after the removal of the epoxy?

i think he was talking about the removal of the glue cuz technically if its ihs pressuring the core or if it was the cooler sitting on the core direclty and pressuring it, its the same thing. Ill be glueing mine soon

There's no need to even remove the black adhesive Intel use. The delidded 477k's ocuk sold were left with the glue in place. Just the paste replaced with clu/p and the ihs stuck back on. Temps still vastly better than a stock chip. Removing the glue just lets the ihs sit closer to the die.

pete910 your story is reason why i dont bother with any cpus that need DE-LID to have proper clock. I cant afford blowing 270 pound cpu up... Reason I went HW-E 250 pound DDR4 is cheaper than broken 270 pound processor :/

...and thus..lower temps
