Title: Does r9 380 2GB have any different hashrate then 4GB Post by: radres on June 13, 2016, 10:43:11 AM Hello guys,
I am planning on buying either one of them. In my local store, they have a price difference of 20%. I wonder if I buy the cheaper one I'll be losing value.

Only problem with 2GB is the DAG file is always increasing, so in maybe 6 months 2GB will not work anymore.

That make this cards very good for etherium, it can be run 1000 core clock or lower with downvolt and make 25mhs with low power consumption. But there is a risk that this 2 gb cards will stop working with dag file rise.

We might be able to mine the Etheruem for 12 months before it becomes PoS.

For example MSI 380 2G with Samsung memory you can easy overclock to 1660-1700MHz, but 4GB version with Elpida memory no chance to overclock.For other brands , it is similar situation. |
