I can't get to 5GHz....Stuck at 4.9 on my 9900K

If I use the system for minor tasks, I can run it at 5.1 with just over 1.32 volts. However, any attempt at running a real stress test and it either throttles from heat and blue screens (with the occasional hard lockup).

If the new CPU doesn't do any better, I will stick with 4.9 for a little while and then order the delider and direct die mount and have at it. It seems pretty straight forward, but I'd like to get a few months out of the CPU before I run the risk of damaging it.

Sure, I did the same!

Had it @4.9 for the first half year before delidding

Well the new chip came in and got installed. I reset the BIOS and immediately went to XMP, all cores 50, all AI or Asus enhancements off, voltage 1.285 and no AVX offset. Results so far are promising. Prime95 in place and blend ran for an hour each with a max temp of 80c. I ran Cinebench15 and 20 multiple times without issue (will attach images), Realbench stress test ran for an hour without issue and OCCT 5.1.0 ran for an hour on both large and medium sets. I wanted to get the tests that I know mean a stable machine for daily use before I tried the harsher ones, try a higher clock or keep current clock and lower voltage.

Just from these tests I know the last CPU was of poorer quality than this one. I can do all these tests at 5GHz on this one while the last one either failed or got too hot.

Anyway, thanks to all for the input. I'll be back to post more results.
