I'm using vertminer to mine Spaincoin (SPA) which has recently been changed from a Scrypt to a Scrypt-N coin.
I'm running vertminer under CGWatcher. I simply renamed vertminer.exe to cgminer.exe so that CGWatcher's Profile Manager recognises the executable.
Specs:
- Windows 7 Home Premium (64-bit)
- 3x Sapphire R9 290X
- AMD driver: 13.251 (aka: 13.11 beta 9.5 from Guru3D)
- AMD SDK v2.9
- vertminer-0.5.3 (download from this thread) (renamed to cgminer.exe as mentioned above so that it works under CGWatcher)
- I do not use a config file, I just set everything with command line arguments as follows:
--scrypt-vert --worksize 256 --thread-concurrency 14334 --auto-fan --auto-gpu --gpu-memclock 1500 --gpu-powertune 20 -I 13 --lookup-gap 2 -o {url}:{port} -u {username}.{worker} -p {password}
Performance:
With intensity set to 20 I was getting 475Kh/s per card, but then I realised I was getting loads of hardware errors and had a rubbish WU.
So I brought it right down to intensity 13, the highest I could go without getting hardware errors. At this rate unfortunately there are more profitable coins to mine.
NOTES:
1) TWEAK YOUR TC as follows: If you have mined scrypt coins successfully before, you need to half the TC you used for scrypt. If you still get a crash, use half your scrypt TC but subtract another 256.
E.g.
- If your original scrypt TC = 28008
- half this value = 14004 (maybe this crashes)
- if half didn't work, then try = 13748
When you get a successful TC:
- increase it by 32 and try again
- if the 32 increase was successful, keep increasing by 32 and trying again until you get a crash.
- then reduce by 2 and try again and repeat this until it works again
- now you will have optimal TC.
