Yes, "really". I was responding to your post at face value (I honestly thought that you didn't have a clue) so I attempted to let you be aware of a fact. That's all. If "discover" touched a nerve in you, that's too bad. If it makes you feel any better, I hereby retract "discover" and substitute it with "find out".
It's not "first rodeo" for the majority of us in here either. Therefore, the common knowledge that the quality of a PSU affects its performance is nothing new in here (or any decent tech forum for that matter) and is not exclusive to you.
To reiterate, contrary to your post (verbatim) that I originally responded to, it's a fact that the S3s have been successfully overclocked using 500W PSUs utilizing only two PCIe power inputs for each unit. I refuse to allow disinformation to propagate.

Since we're all retract-y here, I'll choose one that actually might make a difference: I hereby retract my "a" and replace it with "your" when I was talking about the 650.
Note that I never disagreed with your assertion and even referred to it later. Nevertheless, I still think my response will prove to be helpful, which was my only intent. If you disagree with the crux of the advice (better or more power might be worth investigating), that's fine, but if you didn't then indulging in pedantry for the sake of a side-point just distracts.
Like I said, your OP that I originally responded to appeared to be more of a declaration which is at odds with a known fact rather than an opinion based on a personal experience, hence my attempt to steer you towards the right direction. That's all. However, you've cleared that up since then in your subsequent reply. No need to get defensive. We are all students of the game in here.
As for being a pedant, I wasn't the one who was very particular about and pointlessly quoted "discover" with quotation marks.

In addition of the above linked stuff, the one miner on 243.75 that's still doing beastly ~490 has insane RMP fan speeds in excess of 12/13k. I don't know if this is a readout fluke but (have seen others reports these an speeds) that machine does have lower temps. The other two "slow" machines that are mid to low 470Gh/s with slightly higher temps than the "beast". Is there anything I can do remotely to tell their fans to run a bit faster in the 12k + RPM range to see if that will bring temps down and speeds up ?
If not I will have to talk to my host about alternative cooling methods like say removing the cases which should drop temps (two to three points) to the range I'm hoping for / like seen on the one machine doing ~490 with high RPM's.
Still wondering if anyone here has tried alternative cooling methods like just removing cases and how that worked for you.
Ty.

Who got their s3 kit for s1?
They aren't scheduled till before the 20th of next month.
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.
That's BS. Had I realized they were going to expire before I could mine more coin to purchase more I would have opted for the refund in BTC. Bitmain better make this right or I will also go to a competitor. Customer service and delivery times are what set the hardware manufacturers apart.
Who got their s3 kit for s1?
I've been keeping an eye on the miners, doing refreshes every so often. Here's what I've noticed. It seems when I drop some MH one of the blade temps rise. Similar effect when I gain some MH, a temp goes down. So it would seem my issue is temperature based.
With that said, if this proves to be right and more time well tell as I continue to watch the numbers.
So... what if any alternative cooling methods can be used on overclocked S3's (237.5 and higher) ?

Interesting - that's how I first noticed my problem, but for me it was more to do with the temperature of the PSU itself. That's what exposed it being "on the edge." But, you don't have quite the GH/s dip that I did, so it could well be the miner. Either way, keep us in the loop to what the final answer is. Good luck!
Ok, so were 3 days 5 hrs in on the 243.75's and I've noticed some drops in hash. I know machines have variance of +/- 10% sometimes but it seems like a steady but slow decline. What's weird is the time passed being only 2 days and change, compared to say a month or something.
Anyone else get this with OC'd machines ?
Power supplies. They're probably close enough to the edge of the kind of power the S3's like (beefier than they draw) that just staying hot for a long time is enough to suck hashing power.Anyone else get this with OC'd machines ?
Do you have 2 PSU's on each OC'd unit, or only one? And are you using two separate 6-pin PCI power connectors for each blade (not daisy-chain style) or only one?
My suggestion is to either cool the PSUs and see if your rate goes up, or use more/better PSUs. Poor power doesn't always show up in x's or -'s now that I've been playing a bit with my good S3 and just got 60 GH/s back by adding another PSU.
Worth a try!
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.
He said hat each miner is in deed powered by all four ports on both the PSU / miner using four individual power cables. I have since asked him to please find out the specific make / model of each of these PSU's so the rail voltage info etc. can be looked up to see if maybe, just maybe, it is the PSU's which is questionable a this point since it still could just be system variance / an OC thing.

Or you could have units that never get past 420 GH/s.
I had the same thing until I added more power or used better PSUs, even going from using a piss-poor 850. If you have other PUSs handy, it might be worth it to test that and rule it out to be sure. Other things could be network problems, pool problems, using the same miner, sub-optimal miner difficulty settings, or even the already-noted S3 mining rate instability. I'm sure you've already ruled out most of those, just throwing them out there anyway...

I have a batch one pair that do 430 on 212.5.
I was not able to do better then those numbers. my batch 4 and batch 6 pairs are better.

First image is the 237.5 machine that seems to be "leaking" as well.

Total loss around 27 Gh/s, 26 if you subtract the +1 on machine two.
The S3 exhibits inconsistent and confusing hashing patterns; at least in my case anyway.
At 243.75M, my units could be around 478GH/s within the first hour and slowly improve to reach a little over 491GH/s in the next 4 hours or so. But then again, in a different session, they could also be already at 491GH/s within the first hour and slowly deteriorate to around 488GH/s after an extensive period of time (a day or so) but only to eventually creep back up to between 490-491GH/s and stay there for a while. My pool side averages are much higher (generally a tad over 500GH/s) but just as erratic.
I miss the consistency of the S1s. They were always at 179.xxGH/s from week to week (up to a couple of months) continuously.
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.
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.

They will ROI within 2.5 months as long as you ordered enough of them to beat the curve.
Someone needs to work on their math skills, if one ant is unprofitable then 1000 of them will be as well as long as the cost of running them /ant stays the same.
well it depends.
1 s-3 and 1 evga 1300 for your psu won't roi.
3 s-3's and 1 evga 1300 for psu might roi .
you did say as long as cost to run them does not change but maybe the poster was thinking like I just wrote
I am running 3 S3 (237.5 mhz) on a single EVGA1300 using PCI-e splitters on two machines (so each has 4 connectors).
What was your wattage on EVGA1300 per S3 when running at 250mhz. I wonder if I have enough power to bump all three to 250mhz.
That's what you told me and what I'm using on 3 of 4 miners.
243.75 is correct number.
my 1300 watt evga was able to do 3 s-1's and at freq 400 and 200gh the 3 pulled 1215 watts for 1 month 24/7 . I then backed them off to 387.5 and 190gh pull about 1150 watts ran better using 1150 watts then 1215 watts
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.
Weird, the Ants don't seem to like my 192.168.0.1 gateway as a dns server, which is what every other computer is set to. Set the DNS to 8.8.8.8, and now it's mining just fine. Maybe because your router isn't a dns server/forwarder, most routers just send the isp's dns server ip's over DHCP.
