Is there any news about the development of the etherminer so that it can cope with the larger DAG size. We are approaching 1280MB.

I have heard nothing. I also tested this and found a problem at ~1280 as well.

I started looking on forums as I noticed a substancially drop off on the 7970 cards at ~1.2 GB.

At this point my 280xs are down from 27 to about 24
and
At this point my 7970s are down from 22 to about 17 each (this was what supprised me and this problem is present on XFX, powercolor and one other)

This drop in performance seems to be larger than the expected drop

Oddly enough my 7870s seem to have suffered little if any performance hit and are still happy doing 15 same as at launch.

Edit my 7870s are the ghz edition, however, i also have a sapphire and a 7870 MIST (which is really a broken 7950) both of these are also unaffected.

Food for thought.

Do you find the drop during the test or the actual mining?

I am now dropping in actual mining on this hardware with the dag update at block 840000; the point being is my drop in hash seems to be more than predicted by the size of DAG increase.
