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."

I wonder if there's a market for AMD to just sell these things without the heatspreader?

A gold lined indium tin soldered heat spreader is an excellent thing to have. Removing it is a terrible idea.

The best heat spreaders are diamond silver composites, sometimes also gold plated(Fujitsu uses them), but theyd likely use indium tin solder as well.

A microfinned cold plate on top of one of those heat spreaders would be great. Delidding it and direct cooling is for people who dont know what theyre doing, despite ironic warnings that usually say "dont attempt this unless you know what youre doing".

Only Intel's poorly made processors benefit from delidding, AMD makes theirs right.

To be fair, intel does use solder in their LGA2011 chips.

Intel has such a large and segmented product offering that Intel must stoop to using crappy thermal toothpaste on some of its SKUs to keep them from cannibalizing sales of any products that are the next level above! Intel's large array of offerings is a prime example of what happens in any market when one monopoly interest has no reasonable competition for so many years.

So Intel has been in its classic monopoly product market segmentation mode to obtain more revenues from each and every little small incremental difference in its large array of product offerings for every little price premium over the ones immediately below. Intel has been in that milk, milk and segment more mode and only more competition over a longer period of time will force an end to that way of doing business from Intel.

I agree

Well consider this: if you buy an Intel processor for a certain amount that does a certain rated speed... then what are you complaining about??? Intel gave you what you paid for.

If you have hopes of overclocking this same aforementioned chip to achieve "free" performance, well, then you get what you get. In other words, if you want more performance then pay a little extra and get it out of the box!

Intel (or anybody) is free to make their product the way they make it without your approval or consent. If you don't like it then buy someone Else's product that you like.

The problem isn't about the speeds, it is about the amount of heat generated, and overall waste as a result of using such a poor thermal compound. Think about it, if a chip SHOULD run at 62 degrees C at full load, but is running at 80 degrees due to the thermal paste being sub-standard, that just isn't good. It then forces the cooling fans to run faster to try dealing with the heat, which makes more noise.

So about your concern about temps, i actually do own an Ivy Bridge 3570K that i have overclocked to 4.0 on air, for my airplane simulator that runs 2 cores at 100% load (and my RX-480 also runs at 100% load).

Considering that it normally runs turbo mode (one core) at 3.8 GHz then stretching all 4 cores to 4.0 is not much of a stretch, hence I'm happy with this "mild" overclock. Why not go further? I have my Ram set at 2000 MHz which makes the memory dividers a better match, although with much testing i haven't seen much difference in frame rates, maybe 3 or 4.

Back to the thermal paste issue, ok, i wasn't happy to read about it years ago but the bottom line is, this CPU has lasted me over 4 years and my system as a whole is very obsolete by todays standards, so who cares if it has thermal paste versus solder? I paid for a CPU that comes stock at 3.4 but yet runs at 3.6 on all 4 in turbo mode (automatic) and i can overclock it to 4.0 just by raising the turbo mode in the BIOS. (Gigabyte z77x-UD3H)

Regardless, this will last me until Christmas 2017 when i have a new Ryzen build scheduled. Hopefully by then the BIOS issues will be sorted out, and perhaps an updated 1800x version will be released. I have no plans to buy this under baked Ryzen at launch as the bugs and issues need to be worked out.

Bottom line, you get in a CPU the performance that you pay for, any extra is free and not a human right.

That is a very well built processor, good job AMD.

Would it be over heating if they had just used thermal paste?

This should help longevity as this will quick reduce heat variation.

heat is not what kill silicon (if you have it under 110 celcius) is heat variation. its going for like 30c to 70c, back and forth, on and on.

ex: Qualcomm validated TSMC at well over 100c for years of 24/7 operation.
But silicon dies if you have quick heat/cooling as it physically stress the device.

Best example, freeze a glass.. then poor hot water on it.
Silicon also HATE massive temp deferential.

This is why I like to see my CPU and GPU temperature stay just below 10% of max. (so ~90c)

My 2007 q6600 3.2ghz is still running beautifully. super high temp (stock cooler) because I have the fan at low speed, but it consistent temp.
