Ryzen owners, you can leave your hat on

There are now two less working Ryzen 1700 processors on the planet, sacrificed in an experiment to delid the new AMD products.  The third lived and was tested by der8auer, the mad experimenter, to see what benefits cooling the die directly provide.  The answer is a 2C drop.  This does not seem worth it, considering the high risk, an opinion that Guru 3D shares.  You can of course proceed to do so if you wish, but you might want to buy a half dozen processors to save yourself some time.

"We mentioned in our reviews that you should not delid AMD Ryzen processors for the sheer fact that even the heatspreader has sensors and that it is soldered. Next to that AMD did the cooling part rather well so the benefits of a lower temperatures versus the risk of bricking that processor might not be worth it."

Flipped your lid and want to reattach it?

[H]ard|OCP have been spending a lot of time removing the integrated heatspreader on recent Intel chips to see what effect it has on temperatures under load.  Along the way we picked up tips on 3D printing a delidder and thankfully there was not much death along the way.  One of their findings from this testing was that it can be beneficial to reattach the lid after changing out the thermal interface material and they have published a guide on how to do so.   You will need a variety of tools, from Permatex Red RTV to razor blades, by way of isopropyl alcohol and syringes; as well as a steady hand.  You may have many of the items on hand already and none are exceptionally expensive.

"So we have covered a lot about taking your shiny new Intel CPUs apart lately, affectionately known as "delidding." What we have found in our journey is that "relidding" the processor might be an important part of the process as well. But what if you do not have a fancy tool that will help you put Humpty back together again?"

Living dangerously; delidding your i7-7700k

Subject: Processors | January 30, 2017 - 02:29 PM |
Tagged: kaby lake, core i7 7700k, overclocking, delidding, risky business

Recently [H]ard|OCP popped the lid off of an i7-7700k to see if the rumours that once again Intel did not use high quality thermal interface material underneath the heatspreader.  The experiment was a success in one way, the temperatures dropped 25.28%, from 91C to 68C. However the performance did not change much, they still could not reach a stable 5GHz overclock.  They did not let that initial failure discourage them and spent some more time with their enhanced Kaby Lake processor to find scenarios in which they could reach or pass the 5GHz mark. They met with success when they reduced the RAM frequency to 2666MHz, by disabling Hyperthreading they could reach 5GHz with 3600MHz RAM but only when they increased the VCore did they manage to break 5GHz. 

Of course you must exercise caution when tweaking to this level, a higher VCore will certainly reduce the lifespan of your chip and delidding can have a disastrous outcome even if done carefully.  If you are interested in trying this, The Tech Report has a link to a 3D printed tool to help you in your endeavours.

"Last week we shared our overclocking results with our retail purchased Core i7-7700K Kaby Lake processor. We then took the Integrated Heat Spreader off, replaced the Thermal Interface Material and tried again for 5GHz with 3600MHz memory and failed. This time, less RAM MHz and more core voltage!"
