Area-51m R1, i9-9900K upgrade not working

That system will run the i9-9900K -- are your running the latest firmware for it?  It is 1.18.0. If not, reinstall the original CPU and update it.  Then try the upgrade.

If you're on the latest UEFI firmware, did the CPU come from an authorized seller in a sealed Intel package, or as a used or bulk CPU from an unauthorized source (EBay, Amazon storefront, etc)?

 I have the latest bios, yeah I bought it used on Ebay... dude claim it was working on his System on November 2021...  I got my money back... 

So the system, will only accept brand new cpus never used??

and which sources dell recommends??

my system came with the I7 7700K same chipset, as the I9 9900K LGA 1151 (300 series)

Hi @WiCheSTeR thank you for sharing original Intel Core CPU. 

Please share motherboard Dell Part Number, etc. Thanks. 

Hi @WiCheSTeR  welcome to this free user to user Alienware laptop discussion forum. This is not Dell Support. 

Not all Alienware Area-51m motherboards will accept the Intel Core i9 9900K upgrade. (The i9 9900k has a different socket from the Intel Core i7 6800K Processor) Maybe need to replace the whole motherboard to support it. 

Please share the Area-51m R1 or R2 motherboard specification. Thanks.

The Area 51m is a notebook computer and came with 8th or 9th generation Intel desktop CPUs -- not 7th.

Is this a notebook computer, or a desktop Area 51 system?

As for the rest, EBay is replete with plenty of sellers of altered or remarked CPUs, and given how fragile the LGA CPUs are, anything can happen to them when they're sold in used condition.

ejn63,

WiCheSTeR has an October 2020 Area-51m R1. It shipped with 0PW4K 9th generation i7-9700K CPU.
