Re: Vertcoin - First Scrypt N | First Stealth Address

Can anyone share R290 config I've got olny 500kh

I got only 280X, but try to play with these settings:

Code:

"intensity" : "14",
"worksize" : "64",
"kernel" : "Lyra2RE",
"lookup-gap" : "2",
"thread-concurrency" : "8192",
"gpu-threads" : "2",
"gpu-engine" : "1024",
"gpu-fan" : "10-85",
"gpu-memclock" : "1500",
"gpu-powertune" : "0",
"temp-cutoff" : "75",
"temp-overheat" : "69",
"temp-target" : "65",
"api-listen" : true,
"api-mcast-port" : "4028",
"api-port" : "4028",
"auto-fan" : true,
"expiry" : "20",
"failover-switch-delay" : "60",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"

What your hashrate with those setting for the 280x?

840-880 per card

I get 813~836 kh/s at I=17 and Worksize=256 at 1050/1500 clocks. I don't know how people are getting around 1~1.1 Mh/s at 1020 or lower core speeds?!?!?!....

280X Samsung mem - 1,1MH/S 850/1600
280X Hynix mem - 900KH/S 850/1600
GPU frequency has little effect on the hash memory overclocking gives greater gain.

Thanks, I'll try to up the vram from 1500 to 1600 and I have Hynix vram, didn't know Samsung runs better. So, it looks like the algo is more vram influenced than the core clock.

Update: Tried 1600 and loss some hashrate. Tried 1700 and it froze. I guess 1500 is the optimal mem clock for my card... Roll Eyes
