Guys, whats is the highest value for -ethi that gets you optimum results?

I'm currently using -ethi 16 and I can see a slight increase from the default value (-ethi 8 ). However, when using -ethi 32 or -ethi 64 the miner will report the same total speed, apparently not getting better results.

Any ideas?

On my R9-390 - - dcri 60 got me 870 MHs, and I took out settings for -ethi to none (leave it to CDM to manage), that got me to 29.2 MHs (with -esm 1 settings).
The R9-390 has OC settings of -100Mv, 1020Mhz and 1500Mhz for core and memory respectively, using Afterburner utility, Catalyst 16.5.1

Thanks for your reply but I'm just interested in -ethi settings. Concerning DCR, I'm using -dcri 30 and everything is fine but ETH is my priority Grin

if you have a fast card, use -esm 1 and omit "-ethi", I believe if your have OCed your GPU, you should see CDM pushing the card to the max.
I tried so many -ethi settings on my 5 x 390 rig, and after applying OC and excluding "-ethi", CDM consistently pushed the rig to 29.1-29.3MHs per card.
If I use only ETH mining and take off DCR mining, CDM without any -ethi settings pushed my rig to 29.6-29.7 per card.
All my rigs now are on ETH mining only, OC to the settings above without -ethi settings, and the highest performing results I got.
My cards are only 390 and not 390x, so 29.7MHs per card is great and I am happy with that.
