See where it says this in your crash log:
Hardware event. This is not a software error
Unfortunately your 'new' server is broken. I say 'new' because the R510
is an 11th generation product no longer available from Dell (they're on
13th generation kit now) -- it must be several years old at least.
Try running memtest86 on it and see how long it survives. If memtest86
says something is broken, then it's pretty definitive. (Although when
memtest86 doesn't say 'broken', that doesn't necessarily mean it is OK
-- there are failure conditions that memtest86 doesn't pick up on.)
According to the output you posted one of the CPUs has gone kaput. If
this machine has multiple physical CPU packages, you might be able to
get it to run reliably by taking out the broken one. Identifying which
one that is might be tricky, but if all else fails you can do it be a
process of elimination.
Be aware though that removing a CPU pacckage may mean you need to juggle
the RAM about, as it's fairly common for some of the RAM slots to be
tied to a specific CPU package.
