Sure, just let me know your BTC address.

Looking at your hashrate its much lower than 100 gh/s indicating there's something wrong with your mining. Is your miner reporting lots of invalid shares? I've just taken a look at your shares and 80% of them are invalid. Some miners don't play nicely with vardiff which is probably the issue here, let me know what diff you normally run your miners at and I'll set their difficulty. You'll need to move to port 3329 afterwards.

By "The stats also don't display correctly" is this what you mean? In which case they are displaying correctly as your miner is submitting a lot of invalid work, hence the low hash rate.

Hi all. I've been running rock-solid mining LTC on two 7950s for months, but I'm trying to switch to middlecoin to give the autoswitching a try. Unfortunately I keep getting the windows "cgminer has stopped responding" crash when I try middlecoin. It'll run fine for maybe a few hundred accepted, and then I'll get the crash. I know my rig is solid since I've never had any problems mining on LTC pools.

I'd really appreciate any help getting this to work. Here are my current bat settings


setx GPU_MAX_ALLOC_PERCENT=100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://middlecoin.com:3333 -u 18D9Fwhprh6xXMCsySi4ViPtmT5QxHB8pz -p x --intensity 20 --thread-concurrency 21712 --auto-fan --temp-target 72


The only thing changed here from my stable LTC mining is the middlecoin URL and BTC address as username.

I'm trying it at a lower intensity this evening to see if that helps, but there shouldn't be a problem with 20, since that's what I've been running LTC at for months.

Appreciate any help you guys can provide. I'd love to get this up and running.

Thanks in advance.

What do you think the time frame is? Thanks.

I'm use a VTX 7990 (I think is the same as powercolor). 4x7990 hashing ~ 4600 Mh/s in scrypt with this setings: core 835 @ mem 1375. My first 4 cores are undervolted to 0.925 and second 4 is default voltage (not accesible at bios).
