Just got my two S3's in today, and plugged them in and set them up.

They are both configured to run at 218.75 Mhz from the factory.

For whatever reason, one of them runs at 425 Gh/s and the other runs at 408 avg. The 5s averages are higher. Maybe it will be better when they are "broken in"  

I put them both on an 850W power supply I had, but they both turned off, and started hashing at 26 Gh/s. Then, I put each on it's own 800W power supply, and that seems better. Only using 2 PCIE connectors so far.

Might be the voltage on the power cord coming from the garage might have dropped due to the 100 ft length...

Running out of power in the basement....

One of mine runs at 423 gh/s at 40 degrees C on a ocz 1000w gold PSU.  My other runs at 441 gh/s , Both, like yours at 218.75mhz.

What was that website selling server power supplies with PCI-e outputs? Turns out my 750W E-VGA can't handle two S3s.

Last I checked the complete kit w/breakout board, cables and dell 750w server PSU was $70 plus $15 shipping for up to 3 kits.

exactly, but i edited the initial post (it was 5% at some point, but 2% now)
i see only ~6gh difference between eligius and btcguild, but with 9gh fee difference: advantage eligius or at least a draw.
btcguild on my best machine generates gobs and gobs of discarded shares, with five to ten times less discarded shares on eligius.

Allright, so if one kept a lets say window open there shouldn't be a problem?

[atledenin]

Has anyone run a network sniffer on these things while they are running. There is a lot more network noise than the S1's made. I am not talking about share request/response, I am talking about calls to hosts and socket connection responses(causing extra beep sounds), kind of like a bot.

I have the gift of always thinking the worst of people. Would it be possible a % of the hash power is utilized/reserved for an internal process named "4bitmainpool"?

Maybe its some debug/diagnose thing they forgot to take out?

I first used Fiddler to sniff but setting up a Unix VM for better tools now.

Imagine, what if they could take 2-4% hash power from every S3 miner on-line.............

So that's where the 38GH per unit is going!

[Xian01]

I'm curious why the discard rates are so high in general with the S3's, and if it's something that can't be improved upon.

yeah when I tried 218 or 225   btcguild was brutal.  but my 212.5 freq almost no rejects ,discards, hw.   and the higher report rate.

 So it looks like 212.5  is magic for my 2 units.  oh I set diff at 256 for each worker

[oskuro]

Whats the recommended frequency then, how much GH/s it gives, and whats the power consume?? Thanks

First time BM purchaser! Got my 8 S3s today, 7 run like champs around 441ish, although I have one that has a massive 25% HW errors, hashing at about 60-65% of what it should be doing. Any ideas?

There's been a bunch of ideas/fixes listed here.
The two easiest and most mentioned were:

1.  Swap out your power supply just to rule that out.
2.  Pull off the heatsinks and check for excess thermal paste. Clean thoroughly and reapply.

How many watts at the wall are you all pulling at 441 ghash?

I'll suggest to flash firmware (without preserving settings) from bitmaintech webpage and see how it goes ...

So the firmware on the website is an update to what is already on the system?

For me it was. One of my units had a wrong firmware from factory and start working as advertised after I installed the firmware.
If you look closely to dimaze image you will notice that it show a non-zero value for BestShare but the S3 firmware show 0 all the time for BestShare so I guess he may have same issue that can be easily fixed by flashing the firmware without preserving settings.

After about 3 days mining with my 1 S3 miner it has dropped in speed to 400 gh/s... My 2nd miner that arrived yesterday started at 450g/hs and is down to 430..  I just assume that is it normal.. or did as the 1st one I bought did that.. 450.. 430 for awhile then today 400gh/s.. :S..

Anyone else have this issue?

My one dropped total average down to 300GH/s 5s average was still up around normal 460Gh/s fixed by a reboot now at 455gh/s

Ahh sweet thanks I'll cycle them.
