Bought two E5-2660v4 for total of 100USD.Is there a huge difference between v3 and v4 CPU?
EDIT: Mine have the E5-2640 V3
for example: Sr2n7 REF Intel Xeon e5-2680 v4 (35m Cache 2.40 GHz) fc-lga14a Prozessor | eBay
Have a look on the previous pages, it has already been posted.It would be great if someone with access to the latest bios and firmwares could package them in an archive. Their European support was not helpful providing access to downloads without an active contract with them, although it was stated that they were to be used in a homelab environment.
