Enzo Martino · Nov 2, 2014

Basically i have an MSI HD7850 with 1GB of DDR5 and I wanted to know if its compatible with a 2GB DDR5 R9 270x?

If they're both GCN it might work. My understanding is Crossfire is a bit more lenient on requirements, but I can't say anything for sure.

No. The R-series cards can only be paired with the same cards.
