New build to replace 13 year old i7980x - Help please

You can, but you'll need to look @ the RAM specs, as I did for you in a few posts back, to find out what speed it will run without EXPO. Most likely it will be 4800 as Craig_d1 said, but I've seen a few that are 5200 or 5600.

ok, thank you, i will check back on that and then have a look at the ram i wanted to buy
