Would any of these old cards work?

• HD 5770 1GB GDDR 5 , memory clock of 2400MHz
• R7750 Core 2GB GDDR3 memory clock of 1300 MHz

Thanks in advance!

Is there a way to only mine Siacoin instead of only dual mining with it?

I made some edits to the asic-freq file and got some better results  .

        option 'freq_value'     '0881'  #225M
        option 'chip_freq'      '225'
        option 'timeout'        '55'

Gives me around 120 GH/S with an error rate <1%.

Hey guys!!

 I recently underclocked my antminer S1 (pencil mod) for various reasons and I am getting some unexpected results. The miner is running around 100 GH/S with an error rate above 20%  and I am not quite sure why. I figured I would be able to run this bad boy around 140 GH/S with an acceptable error rate and I still believe it is very much possible(I must be overlooking something). Any and all suggestions are welcomed, below are the settings and adjustments I made.

Board One:
R3: 2.96 R66: 2.89 R38:2.95 R52: 2.93

Board Two:
R3: 3.01 R66: 2.91 R38:2.95 R52: 2.99

option 'freq_value' '0A81' #275M
option 'chip_freq' '275'
option 'timeout' '45'

Seems I jumped the gun as the .115 address is my S1 and not S3 

Fantastic!! I ran a scan on my network and found the S3! (it has 192.168.1.115 as the IP address) and I can connect to it's web interface via wifi.  Thank you soo much   

I am not sure, I am going to post a link to each of my miner's WAN settings to give some more details.

I am pretty new to mining and am hoping you guys can help me with an odd issue I am having. I am currently running an antminer s1 and s3 (upgraded from a s1) on wifi and didn't have much difficulty setting them up. The s1 has an IP address of 192.168.1.243 and the s3 has 192.168.1.244. Both of the IP addresses are outside of my DHCP scope(192.168.1.1 is my router). I am completely unable to connect to the s3's web interface unless I run an ethernet cord from my PC to it and it is very hit or miss with the s1, some days I can connect to it and others I can't. According to my pool's site these miners are up and running.
