I believe it's more of you don't get a continuous path to ground with the chip out. You would have to have the esd cross in a very specific fashion and I just don't think that is happening unless you ground the chip and apply esd to susceptible pins, of which I don't think there are any around the edges if any at all. You shouldn't be touching the pins at all anyway. And no I don't think they have the realestate for zeners on each circuit. I'm not up on cpu design so I could be wrong, feel free to do some research.

This likely explains why there isn't a mountain of dead Ryzens back at RMA Central.

NP, or any series cpu for that matter. I can't remember ever seeing one die from handling except from physical damage. smile.gif

Hehe. I hesitate to tell him my lapping method as he might have a medical emergency. The cpu I'm on now is lapped.

Hit me with it; I'm sitting down in a nice swivel rocker with a soothing mug of tea. wink.gif (And I can include as much or little ESD equipment as might be needed.)

Ok, the first 2 cpus I lapped went like this. I laid a sheet of glass down on the kitchen counter next to the sink. Laid the wet and dry sandpaper down and held the corners down with coke cans. Holding the cpu between thumb and fore finger I held it under the faucet to wet it. Then did the basic figure eight on the paper with the right hand while doing the basic bent elbow drinking beer routine with the left. Periodically the cpu went under the faucet to wash the crud off. Many beers later they were good enough. Cleaned them up and set them on a window sill to dry off. They next day they ran fine.

The only difference with the 3rd one is that I took the box that the last video card came in and cut off a cpu size chunk. Set it against the pins and wrapped it all up in duct tape. I did this because I did slightly bend a few pins on the others. That was the cpu I'm using right now. redface.gif

OK, the grit was attached to the wet&dry paper. What grit size was it (or series of grit sizes)?

In addition, I assume this was due to the surface being concave or convex. How much material did you have to remove (less than it was thick, evidently)?

I started with 600 grit and then went to 1000 grit paper. They were all quite concave. They would be making hard metal to metal contact on the edges while there was a big puddle of TIM in the center. They actually marred the finish of the heat sinks, showing a square pattern.

The lid is plenty thick enough as I have never heard of anyone going all the way through one. All that is needed is to remove all the zinc coating and get it down to bare copper. Musimus used polishing compound on his to give it a very nice mirror finish.

Note that this was with FX, not Ryzen.

Hey guys, finally got the ryzen build up and running but i have a question. I'm trying to update the taichi bios but the UEFI Update Utility section of tools is missing entirely. What am i doing wrong?
