This did indeed bring me great joy.  :-+

Hi,


I'm working on the ADC signal data analysis to implement a more precise A/D conversion instead of the internal decimation of the AD7190.

I have gigabytes of data to analyze, but my actual server based on a Xeon E5-2640 is too slow to do efficient processing while working on the program.
I've ordered a new (old) processor, a Xeon E5-2698v4.

I hope this processor could provide me an efficient data analysis while allowing me to simultaneously working on the program source code.


I've also ordered a PDVS2mini from Ian Scott Johnston to check the new software.

Have a nice day and take care of yourself.

I hope the processor you currently have, E5-2640, is actually an E5-2640v3 or E5-2640v4.  If it's not, the processor you ordered will not be compatible with your current motherboard.  The E5-2640 is a Sandy Bridge family processor and uses DDR3 memory.  The E5-2698v4 is a Broadwell family processor and uses DDR4 memory.  The v3 line is the first to use DDR4 memory.  All prior versions used DDR3 (but note that my understanding is that even across DDR3-compatible CPUs, you can't use v2 CPUs in motherboards that were built for v1, but can use v1 CPUs in motherboards built for v2).

I suspect you have compatible processors here and that "E5-2640" is just an incomplete name or a typo or something.   The packages tend to be designed in such a way that fundamentally incompatible processors can't be used in the same socket, so if you really do have a Sandy Bridge processor right now, you just won't be able to put the new CPU in place.

You're right, I've forgot to write the correct processor name. It's a 2640v3.
Hope having a second processor E5-2698v4 as soon as possible too (dual socket motherboard).

Ah, good.

The motherboard will support v4 processors as well as v3 ones?  For v1 and v2, I think generally the v2 boards will support v1 processors but not vice versa.  Assessing compatibility can get annoyingly complicated but if your motherboard supports the v4 processors then this looks like an excellent choice, especially if you can pair them up.
