New Web Applications Server

     The new server continues to be unstable, it tends to spontaneously reboot when the upper reaches of memory get used.  It may be a bad DIMM.  I also accidentally over-volted the CPU at one point, I meant to set 1.17 volts and accidentally set 1.7, the max for this CPU is supposed to be 1.5v so may have broken down a transistor or two.

     When I bought the RAM for this machine I bought 8x32GB DIMMS as 64GB DIMMS were unavailable at the time.  The Intel engineer did warn me that the CPU had difficulty driving two DIMMS per channel and I probably would not be able to run memory at the memory controllers rated speed, none the less until recently it was running OK.

     Since 64GB DIMMS are now available, I’ve ordered 4x64GB to replace the existing 8x32GB, that way the CPU only has to drive one DIMM per channel and can operate at maximum speed.  I also got a steal of a deal on an i9-10980xe, this is basically an 18 core version of the i9-10900x.  So when this all arrives I will be replacing all the RAM and the CPU.  Also, I purchased a 3000 RPM max CPU fan to replace the 1500RPM fan on the Noctua 15 cooler, with 18 cores I will need all the cooling I can get.  Though this CPU really does not get real hot until you clock the cores at 4.3Ghz or above, below that you can keep the voltage down to where it stays reasonably cool even under load.
