Looking around the internet, I see others with 9900K scoring well over 500GFlops in Linpack at 5000MHz.
 
The best I have done is low 300GFlops at 5200 MHz.
 
Any advice?

Are you using the exact same linpack libraries they are and are you using an AVX offset in the BIOS? Both of those will significantly impact the score.

unstable OC or RAM ?

Not sure about the binaries, but same linpack version.
 
My AVX offset is 0.

RAM passed 1300% HCI memtest.
OC passes LinX with no errors and identical residuals.
 
Cool GTX

Possibly, but I tried turning off everything I could.

Clean Boot



Have not tried that yet.
 
OK, clean boot made no difference.
 
This is strange, because I get pretty good results in other benchmarks like Cinebench and RealBench.

Not sure it can run that tight, it is 19-19-19-39.

Then you're probably not using the same linpack libraries. They make a large difference in score. Even the same version number of AgentGodIBT for example will have different libraries based on when it was uploaded. I would not worry about it if every other test is in the ballbark. Stuff doesn't fail in a manner that it would only have a defect running one particular binary.
 
Edit, had a senior moment... what are your temps under LinX? It is entirely possible to be throttling for temps and pass the bench.  I would not be surprised unless you're under a custom water loop, you're well over 90C at those clocks.

Please use LinX 0.9.5 or 0.9.6.  Not 0.6.5.
If you were the same person posting on OCN, that was 0.6.5 which doesn't even support AVX2, much less any modern processor correctly !

Using LinX 0.9.5 or Linpack Extreme 1.1.1.
