perfect time to discuss miner settings while reward is so low

setx GPU_MAX_ALLOC_PERCENT=200
setx GPU_USE_SYNC_OBJECTS=1
vertminer --scrypt-vert -o 127.0.0.1:5555 -u user -p pass -w 256 -I 13 -g 2 -l 1 --thread-concurrency 8191,8192 -Q 0 -s 2 -E 4

so what do you guys change for 280x's this get me 730kh/s each card scrypt. but only 200 and 250 respectively scrypt-n.
changing TC to 8192 for first card gets me 250,250kh/s.

what else you guys try? I hear 350 is very achievable with 280x's

waltsmith

I get 388Kh/s with each 280X with the following:

vertminer.exe --scrypt-vert -o 192.168.1.68:6857 -u user -p x --lookup-gap 0 --auto-fan --auto-gpu -l 1 -g 2 -I 13 --gpu-memclock 1800 --gpu-engine 1120 --gpu-powertune 20 --thread-concurrency 8192

I'm running two Asus R9 280X TopCU

I think these cards like -g 2 and 8192 TC in general... just gotta play with your clock speeds to tweak them for your specific cards.

You are running those cards way too hard for that hashrate. I get 386kh/s with memclock 1500 and gpu engine 1080. I also am at 0 powertune and undervolted to 1.1 volts. I am also using Asus cards, more than 1 and they are both the same. You should probably try to lower those settings since you are using a lot of electricity overclocking that much.

Mind posting your settings?

-w 256 -g 2 -I 13 --thread-concurrency 8193 --gpu-memclock 1500 --gpu-engine X --gpu-powertune 0

I have 8 different 280x's and they all use those base settings for scrypt and n-scrypt.

All 280X's as far as I know should use 1500 memclock. I have tried other settings and the hashrate just drops.

Gpu clock will vary from card to card, you just have to test to see which one is best for your card. My lowest card runs at 1024 for n-scrypt and the highest is 1080. But the hashrate difference is minimal.

Powertune and voltage will be different for each card. Some of my cards will work at powertune 0, some -10 while undervolted. They all use slightly different voltages, but I found 1.100 works the best. One of my cards I can't undervolt at all or it crashes.

For n-scrypt, I have better hash rates with Vertcoin-CGMinerAleksNR3 instead of the vertcoin miner. NR3 is a modified CGminer for n-scrypt. I can't find the link anymore for that one.

For regular scrypt, I get better hash rates with Kalroth's modified cgminer at k-dev.net/cgminer/

on my sapphire 280's engineclock 1050 I get 250 khs, if i go to 1000 I get 360. It's touchy like that.

can anyone please help me to figure it out why I cannot get in?

I turn off the mining pc and it still says that my mining pc is still on. and also got the token error msg. Sad

Thanks. I'll try that. Haven't really tuned for scrypt-vert yet... that was just what I got using my regular scrypt settings.

why so few 1 GPUcoin per block Huh

At least two purposes...First is so there's no insta-mine right at launch... the second is if there's way too much hashing power with that low of a difficulty, there's a high probability of a fork / failed launch. Doing it this way gets the ball rolling before the big miners jump in.

and when we know it is a failure or not?

Well it's technically already a successful launch.. since pools are up, no forks, easy enough to get nodes.. difficulty is where it should be. Just waiting to hit the rewards now...

Staggered launch is good but this is extreme to wait 2600 blocks. Also the minor to the major reward is gigantic, 1 to 20000 right. So this is like the launch before the launch, it is a cool idea and should have been done ages ago.
Its a rolling start, I agree it seems like it'll work 'under load'

PM for journalist,typing,and data entry services.

If you could get some 750 tis or r9 270 gpus for us heat/noise/power sensitive miners, that be great Grin

270x aren't worth it, even with $30 bucks off. They require an extra 6 pin for like 20 hash.

I tried another pool. is it samething.

I still cannot login.

I got this msg:

You are mining GPUCOIN now ! Look in Getting Started for help

Did you create a worker on the pool?
Or maybe you have to check your mail for verification....

I have create a worker on the pool. it is mining right now.

I donot get any mail for verification yet.
