Question

Intel

There is a server with an Intel S5000VSA motherboard , it had 4 kvr667d2d8f5/1g slats , bought 2 new TS2GAPMACP8U-T
Situations such that two new slats do not want to work with four old ones. How to be, can switch something in the BIOS?

Answer 1

you have modules of different sizes, at least you need to turn off the dual connection for the operative and it’s not a fact that it will also start without it

Answer 2

If the new memory is not listed as tested, or the module combination of modules is not valid, performance is not guaranteed.
