Massman Posted September 23, 2015 Share Posted September 23, 2015 (edited) Just wanted to check who's having problems with the tiny PCB of Skylake CPUs bending in the socket after delid? Some folks are talking about it on Facebook ... check the picture below. Anyone else with similar experience?

der8auer Posted September 23, 2015 Share Posted September 23, 2015 The PCB is only 0.780 mm thick so it will bend without IHS if you put it back in the socket. just too many pins and the PCB is not thick enough for that. Quote Link to comment Share on other sites More sharing options...

This one has never been used without IHS Roman. Edited September 23, 2015 by pepinorang Quote Link to comment Share on other sites More sharing options...

Sure, but normally the IHS will keep it straight and/or the socket frame will fix it. So not really a problem for normal people Quote Link to comment Share on other sites More sharing options...

So not really a problem for normal people Oh, yes agreed! Though Haswell CPUs won't bend if you accidentaly drop them from 50-60cm height on the floor while Skylake will bend real bad (which I also agree should not happen in the first place)...

Crew Vivi Posted September 23, 2015 Crew Share Posted September 23, 2015 i experienced this on both my cpus. one died, one survived haha Quote Link to comment Share on other sites More sharing options...
pepinorang Posted September 24, 2015 Share Posted September 24, 2015 Different issue, but this one also crazy : https://www.facebook.com/photo.php?fbid=10153659222416917&set=a.10150201543751917.312045.537406916&type=3&theater Quote Link to comment Share on other sites More sharing options...
zeropluszero Posted September 24, 2015 Share Posted September 24, 2015 dead link. this is really convincing me not to delid a cpu. Quote Link to comment Share on other sites More sharing options...
pepinorang Posted September 24, 2015 Share Posted September 24, 2015 (edited) dead link. this is really convincing me not to delid a cpu. This: It's from Fugger's FB: "6700K Retail popped" he also commented "Trying to push it too hard, 1.9v @ 6.2Ghz XTU goes pop -155c" Edited September 24, 2015 by pepinorang Quote Link to comment Share on other sites More sharing options...

GtiJason Posted September 24, 2015 Share Posted September 24, 2015 My delidded 4690k had warped so bad it wouldn't even post. I just used a makeshift jig and turned cpu upside down and very slowly heated it up with blow dryer and heat gun. Once straight I re-lidded with Kryonaut and lots of black silicone to keep IHS from separating from pcb and regain it's rigidity. Wonder if we can fashion some sort of brace...

Crew Vivi Posted September 24, 2015 Crew Share Posted September 24, 2015 Any idea how to prevent it? dont use a box cutter, it has a bevel which forces the PCB down when you slice it in. WRONG: use a minora blade RIGHT Quote Link to comment Share on other sites More sharing options...
pepinorang Posted September 25, 2015 Share Posted September 25, 2015 (edited) Yesterday evening I wanted to push Cinebench some more to improve my score. However, CPU refused to take more than 6.1G while it could do 6.3G before... After unmounting (mounting was good), I noticed my chip was slightly more bent than before I start to bench. I didn't try it after session and left it like this until now. I just did and it's f***ing DEAD! #Bendlake I think it's thermal related, I will probably avoid torching pot on this gen. EDIT: And maybe try to glue back IHS too, I was just paranoid that paste would be contaminated by moisture over time...

Crew Leeghoofd Posted September 25, 2015 Crew Share Posted September 25, 2015 you heated up afer the session? to positive temps ? Quote Link to comment Share on other sites More sharing options...
pepinorang Posted September 25, 2015 Share Posted September 25, 2015 (edited) you heated up afer the session? to positive temps ? I torched from -170 all the way to -20, then run XTU until ~60°C in XTU I think I will now use heatgun for CB and unmount pot cold, let ambient temp heat up CPU.

Crew Vivi Posted September 25, 2015 Crew Share Posted September 25, 2015 my 4770k lost little bit of mhz every session after i glue it back. i would stick to fresh paste each session, but be gentle guys!!! cpu's super fragile physically. maybe get your wife to delid and mount Quote Link to comment Share on other sites More sharing options...
Crew Leeghoofd Posted September 25, 2015 Crew Share Posted September 25, 2015 (edited) maybe the heatup is too fast, not realy fond of this architecture. The fragility scares me. Most CPU's die with either the delid or after a perfect fine session... Especially the latter is like wUUUUUUUUUUUUUUUUUUUT happened here?

pepinorang Posted September 25, 2015 Share Posted September 25, 2015 A big guy just told me that he never torch more than -40, then use XTU to +20 and never had issues with PCB bending so it's probably just my fault. However, that kind of s*** never happened to me on 5960X... Quote Link to comment Share on other sites More sharing options...
Guest TheMadDutchDude Posted September 25, 2015 Share Posted September 25, 2015 That's because the 5960X has a much thicker PCB. Quote Link to comment Share on other sites More sharing options...

My point was that it happen on Skylake because PCB is too thin/shit. Edited September 25, 2015 by pepinorang Quote Link to comment Share on other sites More sharing options...
