Whats your opinion on E5-2682 v4. I can get those for $21.6USD. So kind of like $5 more

Should I get Xeon E5-2680 v4 or E5-2697 v3 ? (alien.top)
 

I am looking to upgrade the cpu's on my Dell precision T7810. Both of them prices same in Aliexpress. $16. Budget max $20usd per cpu.

I am leaning towards 2680v4 due to less power TDP of 120W vs 145W. Would like to know the opinion from the community. I will be mostly using this machine as proxmox VM and TruNAS with 2x 6TB drives.

I am also a bit confused if my DDR4 2133 memory will work with this v4 cpu since it says 2400mhz for this cpu. Can it work with 2133mhz memory?

Can I use DDR4 PC4-2666V ECC RDIMM on a motherboard that supports DDR4 PC4-19200 ECC RDIMM? (alien.top)
 

I recently got a Dell Precision T7810. Comes with 8x 4GB DDR4 PC4-2133P memory. According to spec it can support max 2400Mhz ECC RDIMM memory, which is PC4-19200. https://www.metservers.com/assets/images/Dell_Precision_Tower_7000_Series_7810_Spec_Sheet-METServers.pdf

I found some Samsung memory sticks on ebay which according to spec is PC4-2666V.

Question is if I get those will it work? And if working what speed it will be working?
