Hi,
There is an issue with your miner.
The kernel cache created for the
Radeon 280X and Radeon 270X are created for monero with the same name: g9_CNV8_w16_f8_hm1_ha.srb
If you have a system which combines 280X and 270X cards, then you can't use both card, since the kernel generated for one type will fail on the other.
You should generate different kernels for the 280X and 270X. Thank you.
You are right, the whole GCN1 family is put under the same id (g9), i supposed that a pitcairn binary should work on a tahiti etc.it looks like it's not that way.
I will separate them in the next version.
Can you tell me how are speeds now with the Tahiti and Pitcairn, compared to other miners?
It's a bit complicated with the speeds.
I would say they definitely went up for most cards, the 270X has a massive boost, hashing now at 400H/s.
The 280X is now hashing at around 440 H/s which is also an improvement.
The 290 went down to 460H/s initially from 540H/s, but after some tweaking, it went up to 520 H/s.
I only use R9 cards with your miner, the Vegas I have are mining ETH.
There also seems to be an issue with the off-temperature
this is a config example:
{ "id" : 0, "kernel": 1, "intensity" : 60, "worksize" : 16, "threads" : 1, "double_threads" : false, "target_temperature" : 90, "target_fan_speed": 2500, "off_temperature":90, "adl_type": 1},
But the miner still switches-off the video cards at 85C.
Also, I'm not sure if the fan controls work well for Pitcairn cards, most of the time they read 0 rpm or somthing like 10000 rpm and don't seem to spin at all.
