Another question: I just set up and configured one of my S3s, and it was hashing fine, until I rebooted it. Now, it never starts hashing. The miner status page never shows anything, it never pulls more than 45W, I'm not getting any shares, but 'top' tells me cgminer is using 2-30% CPU every couple of minutes, which I'm assuming is it checking into the pool and prepping more work (that never gets used...).

Ok, I put it asside, and moved onto setting up my next one. Idk what I'm doing wrong, but this one's doing the same thing. I've narrowed it down to when I change the pool info, but I'm using the exact same pool info as all my other Ants (Ctrl C+V right out of a spreadsheet), and cgminer isn't loading once I change the pool info. I've tried just one pool, then the other.

Is this normal?

rebooted how: cgminer, power cycling or poweoff -d command in ssh?
In my opinion S3 does not "like" to be power cycled, especially if you don't give it 10-20 sec before turning it back "ON"
try rebooting the cgminer in . It might work.

Yep I usually reboot them through the web page. When that didn't work, I did power cycle it for ~10-15 seconds. See above, as I think it's just a config issues...

I had a solid gear psu that fried an S1. Avoid them at all costs!

For me, they're just anemic, but I knew that going in. But yep, I'm probably cycling all of my cheapos up as soon as I can.

Actually, it does matter - I have an 850 Watt PSU that can't handle OC'ing a single S3 (barely handles stock speeds). It loses hash compared to now that I run the 850 one one blade using two separate cables from the PSU (i.e. not a single cable from the PSU that has two 6-pin PCI connectors) and one 600 on the other blade.

Yep, a single 650 will likely not be able to handle OC'ing one S3. IMHO.

Was that 850W a single 12V rail PSU?

My wimpy 850 was single rail, rated at 58A. The voltage stability and level on cheaper power supplies can have a lot of variance and can even be just under 12V on a multimeter. Don't trust ratings alone. ;-)

What brand?

It was a SolidGear Neutron 850 - it's what I had lying around and thought/hoped it would work. Not so much. Roll Eyes

Question: has anyone tried taking these apart, and applying small heatsinks to the DC-DC converters, like people used to do with the S1s? It was my impression that in early models, these were the limiting factor in being able to OC, so keeping them cool might make a difference?

apparently, some people did (plus on smaller black chips) with no discernible positive effects (i don't have links).
Also, the fact that batch 5-6 were much more stable and OCable also shows that it was just something that was fixed by Bitmain (without heat sinks).

Ok, well no word back yet from he guy hosting my machines but I'll see if when he replies I can get hard numbers on the current PSU's and go from there. I guess all I'll need it just the brand / model.

I just don't want to continue losing hash like this.

could it be just fluctuations: mine keep going up and down, even in the average at the pool.

Possibly and that's what I thought, but it seems like a drastic drop for 2 days and change. At least on the one miner that lost 16.xGh/s

I'm still gonna post the PSU info when I hear back from my host.

You only need to read a few pages back to discover that miners (including myself) have successfully been OC'ing S3s with mere 500W PSUs with only 2 PCIe power inputs.

Yep, an OC'd S3 will pull a hair over 30A on the 12V line. Your PSU has to be able to supply at least 30A, but as long as it can do that, you're good.

Yes, I've been following this thread since the beginning. ("discover" - really? Nice.)

But I'm talking about his results and the fact that his situation with his 650 matches my experience with a wimpy 850. The QUALITY of a PSU is more important than the rating above a certain level (and 500 sounds about right for a really good high-efficiency PSU).

I'm not as concerned with the 2 PCIe inputs as I am with good PSUs. But if you have a weak one with separate weak or marginal rails, then 2 inputs per blade could very well help. My thought is that it is the "sag" the poorer powersupplies experience with a strong maintained load that is the problem.

Back in the day with AM Cubes, we had the same persnicketiness with the quality of solid, stable PSUs. I had a couple of server 750s that would each run 2 OC'd Cubes no problem at a time when folks sometimes couldn't get their Cubes to run with a single 750 (or even 850).

This is not my first rodeo, but thanks for your kind input. I stand by what I wrote, and I think he would be well-served to try better (or more) PSUs - it worked for me, and his stated symptoms match what I was seeing.

My friend hosting them said and sent pics that each one is on a singular supply of 650W or greater with each miner using all four power ports.

Should I find out the specific PSU not that I think it matters with each one being 650w or greater.

Edit:

--- And are you using two separate 6-pin PCI power connectors for each blade (not daisy-chain style) or only one?

I actually just shot him an email about this but do you mean four cables using four ports on both the miner and PSU ?

I also dont get the beefier thing.

"beefier" just means more stout, stronger, tougher - in this case, more stable and more able to hand a hard, steady drain.

I went to use my 3 unused coupons today from the Bitmain Hash speed issue and found out that they expired.

What a crock of crap.

If they dont give me my coupons back or the equal bitcoin I will not purchase their products anymore.

Has anyone else had this happen???

Someone already said it expired last week so I think.

you are the first that admitted to letting this happen. many gave them away sold them or used them. no one else confessed to letting them die.

I believed the coupons expired on the 16th, and now it's a week later. It was posted up and down this thread so you'll probably get no sympathy. Most tried to sell their coupons last minute.
