Has anyone calculated the marginal Watt per increase in GH/s?
Say you clock from from chip_freq 393.75 (202GHs) to chip_freq 400 (205GHs).
The increase in GHs is 3. If this requires 12W more, then the marginal Watt/GH/s is 12/3 = 4. Hardly profitable (depends on $/kWh).
I think mining has reached the point where overclocking may no longer pay off. However, it needs to be tested.
Topic: BITMAIN Antminer S1 support and OverClocking thread - page 11. (Read 144978 times)
Formula: https://bitcointalksearch.org/topic/m.4549088
The number in brackets is unimportant. Just a multiplier (16x = 400, 15x = 375, 14x = 350)
The chip_freq is unimportant. The antminer speed is based on freq_value.
Changing chip_freq will only change the number displayed as "Frequency" on the "Miner Status" page.
The GH's I calculated according to a formula: (chip_freq / 2) + 5 = GHS. Seems to be spot on

does anyone have a problem with it? any errors there?
Just a check question...
When using multiple miners on a p2pool, should we be using multiple wallets to get paid? We have noticed a huge drop in BTC since moving from BTGuild to p2pool.

P2pool has a very high variance and a big streak of bad luck lately. So there's that.
I would always suggest using a single address/wallet for p2pool so that you can take advantage of shares found. To use multiple wallets on p2pool would be shooting yourself in the foot.
Thanks for the advice. Is there a recommended site to download firmware and what not from for these? I've tried a few sites from within this thread, but they seem to be dead..

ionux,
Many thanks for the info.

Hola everyone. I have a number of S1 units running at the following OC setting ->
option 'freq_value' '4e81' #375M
option 'chip_freq' '375'
option 'timeout' '37'
Seeing as how I don't have a KillaWatt handy how many watts should I expect this setting to pull at the wall? Thanks in advance for your reply.

You should be pulling somewhere around 400 watts at the wall for an OC'd S1. I wouldn't go higher than 375, either. I've read their VRMs can't take that for very long. YMMV.

Have you tried resetting it? There should be a tiny black button on the controller card (the card you plug the network cable into). That should reset to factory default. That reset my antminer's IP after I set the internal WAN IP of my antminer to the same as it's LAN IP, and locked myself out.
That worked! Thanks!
Are there any errors in the system log? Maybe the kernel log?
there was errors but I don't know what to make of themAlso, what are you using for a PSU?
dual rails can be an issue - are you sure the load is split properly, not 400W off a single 300W rail?
also, you dont need the 'stratum+tcp' i just use us1.ghash.io:3333

I just did this, and I immediately noticed 2 things...
My temperature/fan reading has gone up from 47/44 @2100rpm to 49/45 @2280rpm.
I'm also now getting TONS of 'discarded' showing up. I was getting 1 discard for every 8 accepted. I'm now getting 2 discards for every 1 accepted.
Is that bad?
Hi Melech, I installed the same FW on my Ants, and as you said, the temperature increased from 4/5C leaving the S1s at 48/50C @ 2220rpm. I use them to eat my home, and I get a nice 21-22C in the whole house

update cgminer to v4.2 can cause temp rise?
why would anyone want that?
mine is at v3.12 with current temp at 400mhz 49c/48c, hardware error is at 5%
not much circulation in an unused toilet in my house
so should i update or not, any benefit to overclocking/performance of hashing?

650w, antec earthwatts, 80plus bronze, dual 12 volt rails
Looks like plenty.
