I couldn't figure out what chip it is since I couldn't get them to boot. I was using stock recommended ram for each platform to make sure that there isn't ram incompatibility. In both cases CPU was indicated by the motherboard as the issue.were you able to figure out if these chips were the xeons or i9s? Did you try different ram with each board? I guess we could always delid them at this point! I am assuming that the xeons would be soldered and the i9 would just have thermal paste between the die and the IHS. It may very well be futile but would be great if we could get them working.
best,

I also thought about deliding it also to find out. I think it's the only way. Or try reading the pirom chip with an rfid reader.
