post #18951 of 33565

Well, delidded mine tonight (4770K).  Used the vice and hammer method - the first three knocks or so didn't seem to do anything, so I gave it one more good whack and the chip flew clean out of the vice.  Luckily I had heard the story of the other guy that happened to and put a towel behind the vice, but I was still pretty worried about knocking those surface mount components off.  Turns out to be fine, but I'm still stuck using MX-3 on the die until the CLU comes in next week, so I only got a 5-10C reduction.  Currently testing at 4.4 @ 1.33V (although it idles at 0.750V) so it appears I didn't get the greatest chip.  Still some tweaking to do though.

 

By the way - how does everyone keep the IHS centered while fastening the socket clip thing?  The one on the Gigabyte board is the kind that sort of slides into place, and it keeps moving the IHS when I lock it down.

If you place any on the underside of the IHS it should only be a very light staining, no excess of any kind. You can do it with just what remains on the brush from doing the die, and you only need to cover the part where the die goes.

It is really thin on both die and IHS, just on the IHS I perhaps wiped it over a bigger area than necessary. But just in case I'll wipe it all off and start again.

Still my actual question was: is it bad to leave some on the PCB?

Indeed. Two or three sharp taps with the hammer and it's loose. I was surprised how easy that was.

place the IHS farther up and slide it back to the normal spot.

mx-3 is terrible. Hell, mx-4 is terrible.. Getting a 5-10C reduction using MX-3 is awesome. You should be able to collect that extra 10-20C using CLU. As in 10-20C over where you are now.

As for the IHS being centered - well, you don't. It doesn't matter. Think about it. It doesnt matter if it's centered, it's all the same.

But really, as it states in the OP, you just put the IHS a bit high, and account for the slide.

Why do you say your chip isn't good? Why aren't you testing higher voltage, like 1.4v+?

nope wrong.. if you look at the PCB you see the small black line. that if the IHS slides onto it will not have a good contact at all with the die by any means. It's been proven in the thread before, the placement does matter sir.

I delidded the second one and that went quite a bit better. It was actually harder to get the razor under on this one. I also marked with a sharpy all the important points on the IHS so I knew how far I could go in.

I would not attempt that corner with a razor at all. Do almost everything else and then use a plastic spreader to lift up the IHS.

Here is a photo of the failed delid

And here is a photo of the second one. I think I succeeded, but I won't know till I get to try it tomorrow.

...first off - hats off to doing 'that' twice in a short period smile.gif

...also, re your first chip, I have seen worse scratches (mind you on Ivy, not Haswell)...but with nothing to loose, try covering the scratches with a non-capacitive and non-conductive TIM like MX4...your 1st chip may yet have some life in it...I really have seen that work on delidded chips which looked far worse than what I see in your pic, though it is always a bit tricky to judge just by looking at a pic rather than the real thing...you didn't actually 'sever' anything in terms of traces on the PCB, I take it ? Anyway, good luck. thumb.gif

You would have to be using a lot of strength to be able to knock those surface mount bits off. Solder is quite hard to break, as anyone who has tried to de-solder something can attest to.

I'm a bit sad-face I won't be buying a 4770k....I really want to turn my uber-cooling setup loose on it to see what it can really do. No more of this wimpy 4.5 ghz it-runs-too-hot stuff wink.gif

Too hot still.  Goes 80+ with 1.33V and 90+ with 1.35V (Prime and IBT) - although that's running silent mode on the cooler.  So I need the CLU before I can push it higher.  Seems like it has a lot of temperature variation also - ranges from 60 to 80 while running a single iteration of IBT, I don't remember my Sandy chip swinging so far.

I bet the guy who cut them off with the razor blade doesn't think so.  I was just shocked that it came completely off - the earlier hits must have loosened the glue more than I thought.

^This!
Just cut one corner with the blade and then slide a plastic card all the way through, greatly reduces risk!

look at the caps on the top left closer buddy I believe they are damaged. If I'm mistaken tell me tongue.gif
