Not all video cards have hash rate (Monero v7 POW)
I'm currently using v2.6.0-beta1 for Monero v7 POW. However, I am currently unable to get hash rates from my other cards (they were working before the update). I am currently using Radeon 6950 / 6970 2GB cards. Most of my configurations use around 6 cards per miner. However, it seems like a few of my cards are not getting any hash rates at all.  All my miners are using Catalyst 14.4 because no other version of Catalyst allow XMRig to see the full 2GB of memory per card. Is there anyone that could look into this as this is now the only mining software I can use for the new Monero fork? I appreciate all the efforts you guys make in supporting miners such as myself with older hardware!
