I already read some threads about this topic but just want a confirmation from Gary or experimented "old users".
I noticed recently some "board communication error" coming from 1 of my 2 pci cards, this appears only when I Use the dsps: meaning my default project with only a few effects is always OK but when I load a synth or other plugs I get this communication error. So the conclusion Gary pointed in the past is either:
- One of the cards is dying
- try to clean the pci gold contact
So I would like to try this and just need a confirmation:
Is contact cleaner OK for this?
Is Isopropyl 99% OK?
I hope the card is not dying as I work on a big project actually and I am near the end... I will try this when this project will be finished. Then it will be the time to change my config but I would like to keep this old config if my pulsar and luna still work OK

Thanks for your help!
