I have a 6 GPU Rig and I have 1 card throwing out a lot of memory errors. Yesterday I think I have about 600,000,000 errors on that 1 card before I even noticed it.
My Rig does not crash, I have a very good Valid/Stale Share Ratio (Approx 1% or less sometimes). They only way I knew I was getting errors was because I have been trying to learn to overclock/undervolt more and more so I downloaded HWinfo and noticed it there.
Should I be worried about the GPU errors if my Rig is running very stable. Card is XFX 570 4GB and hashing about 28 mh/s.
I plan on trying to play with the card some tonight or tomorrow after I get some chores done but if anyone thinks of a possible solution I would be glad to give it a shot.
I am a very slow learner when I am reading and applying new things (alone) for the first time.
I am also looking for someone to do some small 1:1 lessons to possibly help accelerate the learning curve if you know someone or if you can teach it yourself, shoot me a PM. Payment will be sent for the lesson of course.
Your memory clock is likely just too high. On some cards the errors dont seem to matter as much and the effective hashrate stays up despite them. On others Ive seen massive drops in effective hashrate and eventually the rig would crash.
Personally I go for 0 memory errors. The added stability affects porifitability more than the 1-3% extra hashrate.
