Hey guys, a couple of questions

1. A friend of mine sold me the "regular" version (non OC, see here https://www.asus.com/uk/Graphics-Cards/EX-RX570-4G/) and I'm about to purchase some more "OC" version (see here https://www.asus.com/uk/Graphics-Cards/EX-RX570-O4G/) in order to finalize my 6 cards rig.

As far as I can tell, the only difference between those version is the core clock. Does this mean that I can use the same bios mods if they got the same memory brand ?

2. Any of you guys owns and mines with these cards ? I'm curious about their hashrate, cooler performance etc..

Thanks !
