Yeah , I got nervous so I backed them of maybe an 1/8 of a turn from the stop position.
Still got the same results.
Got a tip for us?

Delidding-how to remove stickers???

Thanks. I think I figured out it was the new processors I put in. First it was dimm 6, but flip flopping them the bad dimm slot moved to 2, so the issue moves with the processor location.
Give the processor pads a good clean with Isopropyl, maybe you got some glue of the stickers on a pad.
Only can second how dumb some must be to put stickers there.

OMG.
Gently use a squidgy tool but it will take some patience and then finish with a little iso prop.
Already cleaned them with a lot of alcohol. One of them is bad. Could have been damaged when I cleaned it or bad to start with, I’ll never know. Ordered another processor from a different vendor.
Out of curiosity, which vendor shipped the CPUs with the stickers on the underside? Was this an Ebay transaction? Would like to avoid this seller if at all possible, as I am in the market for a new CPU which will probably come form China.
TBH, that’s a very common practice from the Chinese seller. I’ve seen that a few times already. The sticker won’t affect the CPU operation. Leave the sticker untouched may be safer.
The problem is, in china, not only the seller can be the scammer, but buyer as well. The seller also need to protect themselves.
So they need to put a sticker on the CPU (but not package) to identify that’s what they sell. And on a CPU, they can only put that on those resistors / capacitors.
Of course, if you have no plan to return it (becasue you plan to delid it anyway), you can ask them not to do so.
I am not saying that they are right or wrong, but just explain why it happen.
So the sticker being on there, it’s ok to just leave it on there and install the processor? No heAting issues or anything?
No, never heard any issue because of that.
The CPU core may be can reach 100C, but even that’s just few mm away from core, it can easily 10-15C lower already. And even 100C, it’s not going to burn or anything.
If you’re using delidded CPU’s you don’t worry about turns or torque. The screws are designed to hit stops when at the proper depth with delidded dies. If you don’t fully tighten a lidless chip, you will not have full pin contact and see things like you’re seeing now.
The 1/4 turn stuff is what you do if you left the lids on.
Delidded = tighten til screw stops.

I'd mind the glue of the sticker melts at 100 Grad Celsius and smears into the contact needles of the cpu sockets.
Nevertheless, a sticker should never be placed onto the component side of delicate electronics - especially when getting really hot.

Thanks, I tighten until they stop, but backed off 1/8 turn another time I installed , didn’t make a difference either way, but when I redo them again when I get the next replacement processor I will tighten all to the stops.
I’m still not sure what to do if I get a sticker again, leave or remove. Hopefully the next vendor doesn’t put a sticker there.
"bad" ram slot is basically always a problem with the contact between the cpu and the pins. CPUS from China tend to be very grungy with a thin smear of old silver thermal grease on the gold contact pads. They wipe them off but not actually clean. I have installed a lot of used CPUs, and with enough cleaning it has always eventually worked.
Clean with 92% rubbing alcohol.Q-tips work good, scrub for a while and you will see the cotton change from white to grey, and keep using new ones till you get it really clean. Scrub hard in every direction. Also. sometimes there was oil. maybe from fingerprints, and when it bakes it turns into basically an enamel the same thing as the yellow/brown that well used cookie sheets eventually develop. You can still remove it with a very mild polishing compound like headlight lens restorer. Clean again with alcohol and it should work. Also, sometimes its the way the pins line up, and a cpu that wont work at all works fine if you install it slid all the (one millionth of an inch) to one side of the socket or the other.
But if you got the pins on your board dirty... good luck. I won't even try to suggest a way to clean those as it is probably impossible to do without danger of damage. Sounds like you didn't though.

For the CPU socket pins. . . . Australian Eucalyptus Oil using a ladies makeup brush . . lots of gentle stroking and then allow to dry and then one more stroking session with water-diluted Eucalyptus oil = a couple of drops of the oil until it turns white . . then allow to dry overnight.
Its also good for cleaning the CPU face.
Eucalyptus oil emulsifies adhesives and loosens dirt.
if you don't believe me, rub two drops onto the 'sticky' side of a piece of cello tape
