PowerEdge R900 motherboard upgrading CPU's

I have an R900 with a C764H motherboard and four XEON E7330 CPU's.

These CPU's are not supported by VMWare ESXi 6.5  however the XEON E74xx series is.

1) the 7330 is a quad-core, 2.4GHz, 2x3MB L2 Cache.  the 7440 is also a quad-core, 2.4Ghz, 2.3MB L2 cache.  i assume i could simply drop in 7440's without any problem.  is this correct?

2) the E7450 is a 6-core, 2.4GHz, 3x3MB L3 cache CPU.  can i drop these in, or do i also need to change the motherboard to one that works with 6-core CPU's?

3) if the answer to #2 is a yes (that i do not need to change motherboards), could i use X7460 which is the same as the E7450, but with a faster clock (2.66GHz instead of 2.4GHz)?  or do i need a different motherboard that supports the faster clock speed?

THanks

Hi Josh,

just installed four x7460's.  server booted just fine and ESXi 6.5 installed without a hitch.

thanks for your help

Just for the sake of record keeping: I completed the same upgrade to my PowerEdge R900 with the x7460 CPU without any major issues. ESXi 6.5 installs without any problems, but version 6.7 appears to have dropped support for that CPU.
