perfect time to discuss miner settings while reward is so low

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

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.

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

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/

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.

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

payment after the 2600 block will be different right?

[scott0577]

payment after the 2600 block will be different right?

Yes 1 to 20000 coins

[micryon]

Very appropriate..

[Omega0255]

payment after the 2600 block will be different right?

Yes 1 to 20000 coins

It's variable 1-20,000? I thought the blocks were fixed to 20k

[benthach]

mined

[Omega0255]

Very appropriate..

2600 blocks was a bit extreme :/ So much wasted hashes.

Also, aren't the blocks fixted to 20k?

I Hope I can help some 7870's guy

or all the same after the 2600 block will remain 1gpu coin  ?

[scott0577]

or all the same after the 2600 block will remain 1gpu coin  ?

Blocks after 2600 will pay 20,000 coins. No more 1 coin blocks All blocks will pay 20,000 after block 2600.

Blocks after 2600 will pay 20,000 coins. No more 1 coin blocks All blocks will pay 20,000 after block 2600.

ok i'm go smoke and restart rig to CACH ^ 2600 blocks its extreem time
