This is strange, im also on the latest clevo official bios and the 9900k is working with it. Did u try the 9900k in a desktop to see if its working? Maybe the CPU is defective.

 

I'm pretty sure it was defective 😕 bought it second hand so there was a chance it could of been a dud

Tbh, you are better of with de lidding the 8700k, liquid metal and OC the sucker to almost 5Ghz. 

 

Can i use liquid metal on a copper heat sink? or would i need a new IHS? if you have any guides would be interested!

The same happend to me aswell, first 9900k that i got was an ebay one..didnt boot so i send it back and got my money.

 

You need to bake the copper IHS first with LM. On mine i put the Lm on the part where the die makes contact and left it do dry on the heater for 1 2 days until the LM was absorbed in the IHS. You can also bake it faster in the oven if you can stand the smell.😀

yep no worries on that one. itll just leave a silver stain that u wont be able to remove, thats the LM filling the copper pores. but that will not hamper ur cooling capability in any way, its just a cosmetic blemish.
