So I thought I'd post my experiences after having my first S1 up and running for just over 24 hours. I'm used of dealing with various OS's due to my work (deskside support lead for a major cable TV network). I deal with Macs, Windows and even the odd linux box. Which is good since I have mostly PC's at home and 1 mac and and my new Antminer running linux.  Tongue

Open it up, get it hooked up to the new PSU I ordered. No issues there. Fire it up. Use my laptop to connect to it via IP after putting it into the same subnet. Reconfigure the IP settings of the miner and put into the proper range for my home network. Then turn it to DHCP and statically assign it in my router. This way as I add new devices, I can't screw up and assign the same IP and it will always get the same IP from the router.  Grin

Someone a couple of pages ago mentioned a stock speed of 160 GH/S. I was getting 140 GH/S after about 10 minutes after configuring my mining pool (eligius). Start messing with OCing and cooling. Add a second fan. One good thing about being a computer tech...always have extra parts around!!  Cool Late last night, finally get it going to 200 GH/S and holding. Go to bed. Wake up today. Still going. Get to work and check. No good. Hash rate has dropped big time. Remote into my home server and SSH into the device and order a reboot. It comes back to a nicely tuned 200 GH/S. Start to have hashing rate issues again in the afternoon but don't have enough time to really mess with it until I get home.

I have the device in my basement, in my storage room beside my server. Ambient temps in the room were around 79F. Get the AC going a bit more and put a fan to blow cooler air from the hallway towards the miner. Room temp now down to 74F. Temps on the miner are 45/43C with them being overclocked 387 freq. I'm getting right around 190 GH/s. It should be a bit higher but it's also drawing about 375 watts according my watt meter. Not sure if this had anything to do with it either way but I plugged it into a 500 watt UPS just in case I was having noise on my outlet. The only other thing plugged into the UPS is my cable modem (got to keep my network up and running!) and I'm still running around 390 watts so I don't think I should be seeing a drain on the battery.

Anyways, I'll have to keep an eye on it's hash rate. I'm still not convinced I have the issues all quite solved but I should know by tomorrow afternoon. High tomorrow is 86F here in Atlanta.

A quick update. UPS ran out of juice. Had to move the miner to an outlet on the UPS that isn't part of it's battery backup. But I still get the power line conditioning. Everything is back up and running. I'm mining back to 196 GH/s. Nice...
