Hello,

i have a problem with my rig under win 7 (3x 470 4Go)

It worked longer whith blockchain driver + claymore than my win 10 ones, but when I updated to driver 20.5.1 + phoenix, I only have 10 Mhs for every GPU.
They are in compute mode so the problem does not comes to that.

Is it a known problem for win 7?

thx
For Win7 there is no new blockchain drivers. And old ones is too old and can't properly work with big memory buffers colse to 4Gb.
So you need at least Win10 and drivers like 20.4.2.
