I just checked the memory and its Samsung.

I'm having a similar experience trying to mod the bios, but with hynix.

I suspect it is because the polarisbioseditor (I've tried a few) doesn't support these, but not sure. I'll let you know if I figure anything out.

I have wrote to Sappphire support twice and this was their answer:
Which driver that you are using ?

"First answer from Sapphire:
Did you know well about the DAG issue ?
We cannot comment or guarantee the hashrate.
We will suggest to download and update to this blockchain driver -

About the OC request , please look on the forums."

Second answer when i simply asked if they can be overclocked or not.

"No comment , sorry."
