Hi


I did not know where best to post this, so I put it here at the top of the forum’s lists.


Be careful when buying used Intel Scalable possessors – they may have been installed like this.

Warning.

Use this installation method at your own risk - A processor may have been intentionally harmed during the production of this video!




I recently joined the Intel Scalable LGA3647 club and like many was a little nervous about installing the processors, particularly about the torque settings of the 4 installation screws.

There are lots of threads about this and this discussion caught my attention, particularly the emphasis on having the correct type of Torx driver.https://forums.servethehome.com/index.php?threads/xeon-platinum-8124m-18c-3-0ghz-575.29999/


Before my first attempt at Installation, I searched for some instructional videos – I thought they might help.

If you search Google for “Intel Installation 3647” This comes top of the list in the UK.

How to Install an Intel® Xeon® Processor into an LGA3647 Socket

Watch from 5.45

I did not use this method - my installation was OK.


I wonder what genius at Intel authorised this video to be released - Intel really do have some problems.




Have fun and be careful.

The only thing I can spot is that one side the middle screw was completely fastened, this tilts the cooler and cpu to that side. Then on the other side the middle screw was fastened all the way. The two corner screws don't prevent the block from tilting either way when completely fastening the middle one.

So the preferred way IMO is to gradually fasten the opposing screws in the middle a turn at a time, until both are fastened to about 0.8 nm.

If you look at 2:40, you can see they set the clutch torque limit to "6".


This reminds me of another video I'm having trouble finding, in which someone shows how to install a CPU in the wrong motherboard by scraping off some extra rows of pins.

At least this actually works, whereas AMD TR/EPYC socket works only half the time for me and has to be completely redone.

I thought system nerds would start by downloading motherboard manuals before they begin. Most manuals for these newer processors will describe how to install them and include the torque specification: 12 lb ft-in.

It's interesting how processor installation is now becoming exactly like how wheels are supposed to be installed on a car--except that air tools are often used. And there's no problems with that, right? No warped brake rotors, or broken studs, or unexplained vibrations, etc...

I can see the same nature of problems by incorrect installation of these type of processors. The more precise this stuff gets, the less idiot proof it becomes...

Many moons ago, I was once an car-ignorant lad with a auto that came with alloy wheels. I didn't have any impact tool but I just tightened the nuts as hard as I could. Lo and behold the brakes soon started pulsating which made me more informed in this area.

Anyone who uses an impact tool to install stuff is either ignorant or asking for trouble. Taking it off is one thing, as long as it's not the nut that needs wheel locks. The latter happened to my other car 5 years ago. The shop was able to find a replacement nut that fit my lock--sad state of affairs on wheel locks.

So long as proper torque limiters are set you are better off with a power tool than by hand... I have seen hbm die stacks crushed by hand over tightening...but you do need to fasten in the order shown and you generally attach all screws by a few turns to prevent heatsink tilting.

Uh.. I think that as long as you have a quality tool, it would be better to avoid a power driver. You should tighten *gradually*, without reaching the torque limit directly.

May I ask how much torque does Intel officially specifies? I cannot find that piece of information...
