I had some cards laying around since the 2016 mining frenzy, and decided to recently build back my rigs on SMOS.
I noticed though that all my 4GB cards are hashing at 8mh/s while my 8GB cards are hashing at their normal ~30MH/s speed

Is there any way to increase the mining speed for those 4gb cards? They are pretty useless at those speeds, especially their power draw is the same as when they were hashing at ~28
Would appreciate any help in getting those 4GB cards to hash some profits with better hashrate.

For the best profit, set up your 4GB video cards for Ravencoin (RVN) mining.
The profit per day is more than 2 dollars from one video card, this is a very good result.
It is very expensive to buy several system units to connect each video card to the PCIE x16 slot
