I know that I just posted another thread about an issue with my GPUs hashing at low hash rates (on my other computer) but I have a problem with my other miner that runs Ubuntu with cgminer 2.11.4

Now, for this, the hash rate seems to be what it should be (also using two 7770s). The problem (at least it seems like it's a problem) is that I appear to be getting very low numbers of accepted shares.

Here is the info from cgminer
(2s):453.2M (avg):377.4Mh/s | A:0  R:0  HW:0  U:0.0/m  WU:5.0/m
 ST: 2  SS: 0  NB: 8  LW: 92  GF: 3  RF: 0

It's been running for about 10min (I restarted it after noticing the low accepted shares)


Any ideas?


Again, I'll gladly tip in LTC or BTC for some help.

[Config file:]

I've tried searching for information about this and didn't really find anything that answers my question. I have all the various drivers installed and am running cgminer 3.7.2 with (2) 7770s (MSI R7770 PMDIGD5) and each card hashing at around 50kh/s (107.5 kh/s avg) and ~75 WU total.

Now, on the LTC mining hardware comparison chart, the lowest hash rate for a 7770 is 143kh/s and I'm not even getting close to that with TWO OF THEM..

Anyways, if anyone can help me get my hashrate up to where it should be I will gladly tip them in LTC or BTC for their effort (which it shouldn't take much of since I'm probably making a newb mistake)

Config file:

cgminer.exe --scrypt -u x.x -p x -o stratum+tcp://multi2.wemineall.com:5555 --gpu-fan 100,100 --gpu-engine 965,965 --gpu-memclock 1425,1425 -I 18,18 --lookup-gap 2 -g 1 -w 256,256 --thread-concurrency 8000,8000

PS. I had someone help me set this up and he had me input all those values twice, but I never see people do that so please feel free to tell me it's not necessary.

Thanks a bunch!

I recently started mining litecoins as it seems the best way to put my two 7770s to good use. I am running Win 8 x 64 and installed GUIMiner-scrypt alpha which is suppsedly built on the "standard" gui miner but allows for litecoins. Anyways, after inputting my info for the host, username, port, pass, etc for ONE of my cards, it started to work (albeit after a half hour of a status saying "Connecting").

When I set up a miner for my 2nd card (they're identical MSI R7770s), I used identical data (except for the worker name obviously) and it is still saying "Connecting".

Why does this app take so long to connect or start? Every 10 seconds or so the console is saying:
"*workername*": 19s0:0.000 (avg):(0.000h/s) | A:0 HW:0 WU:0.0/

My first worker is hashing away rather nicely while my second one with identical info is stuck on reading "Connecting"

Thanks for the help.

So I got a tower that has 1PCIe x16 and 2 PCIe x1s. I already got a good NVIDA GTX 650 Ti BOOST card (yeah I know I should use AMD but apparently it wasn't compatible). That is giving me around 70MH/s.

I am wondering how const-effective it would be to get two PCIe 1s. Has anyone used a small GPU like this with any success? What kind of performance is possible out of a PCIe 1?

Thanks!
