i believe you will see the decrease in about 10 dags after the 4gb limit is actually hit. Maybe sooner depending on os etc. LOL posted a chart showing when it slowed and i want to say by like 7 dags its was down considerably. Ill try to locate it. Useful info....my 4gb are still going on linux.

Yes this is the post he is referring too. Basically for some reason my rigs stopped on Epoch #381, while for others it should work until #382, strange. It seems that the speeds are "ok" until Epoch #385 which hashes at 82% from full speed, which is around year end. Epoch #390 and on are just not worth it at hashing 50% speed. So I would say you can use it for 3 more weeks and then think about getting 8GB gpus because its going to be highly unprofitable by then.

So, I am using SMOS with PhoenixMiner v5.3-fix and have seen the expected dip in h/r with 4GB cards. Even though this table shows that linux wont take a hit on Dec 11th, that is when my first hit occurred and then another one a few hours ago. I highly recommend this combo as it allows robust monitoring through SMOS dashboard. Granted, that reduction is not optimal but certainly better than the alternative of not working at all and clearly still profitable at least for a few more weeks.

I just got my final 5600 XT today so will likely be converting over 1 of my 470 4GB rigs this weekend, then just let the other 3 chug away until no longer profitable. From there, it's a question of whether top try to sell off all 4GB or mine something else with them. Will be selling the ones off the new 5600XT rig so probably see how that goes then re-asses. The somewhat silver lining is that with the huge GPU shortage, even these old cards are getting more on ebay. Of course, they will likely change when the glut of them hit in the coming months, but something to think about.
