I'm going to be getting another PSU shortly, this was just one to get me started.
I do think this PSU has another rail though. as I was able to get both of the blades running on this psu without underclocking the freq.
Or maybe it can just actually handle what it's rated at. who knows.

Just check if any of the connectors, at any stages, including the adapter runs hot. If not you're good to go even though its a crap PSU, it should be able to handle the 400W~ DC load.

Could check if you could spread the load on the multi rail properly. If you tried to put the whole load on one rail it will shut down to self protect. Ironically lowering your clock when i mentioned you were probably trying to run full clock on a undervolted S1 would of probably given you the best hashrate Tongue

I believe that's what I did, could I modify a molex that's on another rail? I'm not sure how to tell.
As far as undervolting/underclocking I'm just trying to get it to run as if it were stock, I'll deal with all that later.
In my first post you could see I was getting a lot of HW errors running a full clock on it while it was undervolted. Was that probably why?

Like i said, you were trying to run too high clock on a modded S1, you needed to change the timing and clock based on the chip voltage. Not remove the mod. Voltage is what the pen modded resistors changed.

Thats why i said to lower the clock and change the timing. You could of possibly gotten near full speed but saved 100W or lost 25-30% hashrate but use 60% less power. Its just too late to check what clock it was meant to run at by the previous owner now.

Until you can put the mod back, all you can do is figure out how to spread the load on your PSU and underclock it so it doesnt overload it. Some molex to pci-e works, some doesnt. If you have a 2 molex to 1 PCI-e adapter, you might be able to run 1 blade on it slightly underclocked without melting the connectors.

lock the other thread and

drop the freq to 200 or 180

I really wish you did not erase the pencil mod

what is your psu?

show me a photo as I can't tell if it is any good.

I found this link your psu is shit 2 rails

http://www.tomshardware.com/forum/347187-33-will-power-supply-handle-7970

Other thread locked, someone moved it, I wasn't aware.

I already erased the pencil mod. I'll deal with undervolting it after I get a multimeter and can do it myself.

yeah I already figured the PSU was shit, think it would work if I just underclocked it for now?

yes go to freq 175 it should work. a few years ago I wrote a lot on this mod and how to set freq there are threads about it.

Now that you,ve removed it, you're gonna have to grab a multi meter and make it even on both sides. Or you'll get one board not being run at the right timeout/freq. And its possible, the load can do 400-500W, so i'd need to know what the PSU is.

Ah wouldn't you know it, I left my multi meter in my other pants! Wink

But in all seriousness though I'll have to get one, good thing there's a home depot less than a mile away!
and the PSU is a pretty old "Xtreme Gear 700w ATX Power Supply" Its from an old cyber power pc that was built a few years ago.

I see, it should still work for one S1 even running at 400Hz. Unless its damaged or its a multi rail PSU, cant be arsed to check. You could underclock the miner to 200hz just to see if it then works.

Okay so I tried to get the other blade up and running but it powered off my PSU after a couple of seconds, from what I've been reading that's because it can't support the draw that the S1 is trying to draw correct?
But it's also pretty late so I may have just configured something incorrectly.

I might put the pencil mod back on the other side and look into it just so I can get both blades up and running on one PSU.

Thanks again!

I think the stock numbers are 180 GH/s for close to 400Watts. Undervolted you can get 140GH/s for 175Watts. Hence even people with free electricity run them undervolted.

Would definitively happen if you or the person who owned the S1 before you did pen modding.

I didn't know what this was so some googling and took a look at the board and the resistors R3, R66, R38, R52 were all colored black.
I just took an eraser to one blade and that seemed to do the trick!

Thank you for the speedy reply!!

*nod* Make sense. Running them undervolted is a very good though. You can cut the consumption in more than half and only lose 25% hashrate or so. Keep that in mind if you get more, since just the saving on PSU capacity is very good, even when you have free electricity.

Edit: I'm going to check the other blade and see if that's the issue with that one as well! Will post more results!

And then you're gonna have to mess with the timing values depending on the resistance on the pen mod. If its been undervolted and you set the clock too high its going to have crap hashrate.

If its truly stock, then there's probably something wrong with it.

I recently obtained an Antminer S1 from a friend who decided to retire his hobby of bitcoin mining.
I have been following bitcoin since its creation and have been mining on and off for a few years with altcoins, etc. just never had a stand-alone ASIC, so no preaching please Wink
This miner ran fine for him, he returned everything to stock settings and shipped me off with it. I booted it up at home and reconfigured it for my network but I'm getting a real shit hash-rate, and I don't mean a little sub-par, I'm talking 30 Gh/s on a single blade (test purposes)

I've tried multiple power supplies, upgraded the firmware, updated cgminer to version 4.2 and I'm all out of ideas.

Thanks.
