Guys, I have a strange Problem. Hope someone is able to help me. 0.05 BTC bounty for getting my miners to atleast 2,6 Ghash each I got 16 Antminer U1. All are running at 1,088 V. I have a 49 Port USB Hub and a 450W PSU exclusively for those 16 U1. I have additional coolers attached and a fan blowing cool air. The Miners get definitely not too warm. I tried Bitmain´s Cgminer, different BFGminer version on Windows, Minepeon and Raspcontrol. Cgminer gave me too much errors and for BFGminer I have the following Problem: While I should be able to get 48 or atleast 44,8 Ghash out of the 16 U1, I get far less. Recently did some testing with BFGminer 3.10 and Raspcontrol At 4D81 I get 6 Ghash At 4C81 I get 10 Ghash At 0B81 I get 12 Ghash At 0A81 I get 15 Ghash At 0981 I get 14 Ghash At 0781 I get 10 Ghash The Problem here is, that most Miners run somewhere under 500 Mhash. No Hardware Errors. Those U1 who do more Ghash are getting warmer then those who only do some Mhash. From test to test the variance is very big. Currently they run with 4C81 under BFGminer 3.9.0 and Minepeon with 25Ghash. For some reason the hashrates with bfgminer 3.9.0 are similar among all sticks. The best result I got so far was about 30Ghash (also BFGminer 3.9.0 and Minepeon). The funny thing is, that I didn't give any frequenzy to BFGminer in this test so that the Miner should have run with 1,6Ghash. For some reasen they did nearly 2Ghash. This was absolut stable (ran for <24 hours). Again: I do not get any errors (or very very few on some sticks <.1) beyond 4E81. Sorry for the bad english Thanks Muto Hi, take a look at my solution: https://bitcointalk.org/index.php?topic=390929.msg5155376#msg5155376i needed the y usb adapter without my antminer run slow as yours.

What name would you give to the smallest unit of bitcoin (0.00000001)? sat. What name would you give to 100 sats? bit. 1 bit = 1 uBTC. 1,000,000 bits = 1 BTC. It's bits

"nonce timeout" means your antminer is not responding.:
Try to change its frequency to the lowest value.

Does Bitmain have any kind of warranty, repair, or replacement? I have another (separate) Antminer U1 and it seems to be working great. Try the official version of cgminer instead of this unofficial fork just to be sure.

Hey guys, I'm having a lot of trouble getting my antminer U1 (2) overclocked. I guess the frustrating part for me has been I had them overclocked and now after having to restart my cgminer I am not able to get the CMD prompt to read the command correctly.
Here is the command line I'm using cgminer.exe --bmsc-options 115200:20 -o poolname -u username -p password --bmsc-freq 0A81
The result is cgminer.exe: --bmsc-options: unrecognized option
Does cgminer need to be running/not running while I enter the command in CMD? I tried making a .bat file with this command with no luck. I uninstalled cgminer and downloaded a new version... Command cgminer.exe runs the miner no problems. I'm thinking its something with the command line and I had trouble with it the first time I overclocked. I keep finding command lines that are similar and pasting them in (editing pool user and pass) with no luck. Do I need to be using a specific version of cgminer?
Thank you for your help

Some examples for 2.0 GHash/s: cgminer.exe --bmsc-options 115200:20 -o pool_url -u user -p password --bmsc-freq 0981 Should work with Bitmain's cgminer 3.8.5 fork, found here.cgminer.exe --anu-freq 250 -o pool_url -u user -p password Should work with the latest official cgminer, found here.bfgminer.exe -S antminer:all --set-device antminer:clock=x0981 -o pool_url -u user -p password Should work with the latest bfgminer, found here.And last but not least, BitMinter's (Beta) Client will run them at 1.6 GHash/s.

Messing with these U1's today, found an easy way to overvolt them... its a complete shot in the dark but....
I pencil modded the contacts where the R2 resistor usually goes (stock there is no resistor). Have no idea what the resistance is that I got to cuz the voltmeter I used to measure is shit as hell on resistance measurements...
But, I got the asic up to 1v doing this
Clocks seem stable at 300mhz @ hashrate of 2.4GH and HW of 0 for the last 8hrs =) Probably could clock it higher, I tried 325mhz but it stops hashing after like 20mins... think the USB may not be up to par in supplyin enough power to it.
I have a fat old P4 chipset NB heatsink on the heatspreader, its definitely runnin hotter than before ...

I quite don't remember seeing an answer for my following question, so excuse me if somehow I'm duplicating it but, what is the real impact in the hashrate of those hardware errors? Does it mean that hashing at 2.2 with 5% HW is the same as hashing at 1.8 with 0%? Basically, is it worth?

IF it was a straight 5% HW loss, you'd be looking at 2.09GH/s. I doubt this is the case, so yeah, I'd say worth it. The life span of these (really any ASIC miner) is pretty short. Run 'em while you can!!

Basically, you take a standard lead (graphite) pencil, and make a line between the two contacts you want to connect/lower the resistance of(?). This was bandied about for the BE USBs if I remember. JUST KEEP IN MIND, you can ruin yer equipment with this type of trick. Be sure you don't mind frying one, and if you need more explanation than I gave, then you probably shouldn't try. Don't let me stop you though: https://bitcointalk.org/index.php?topic=524358.msg5814070#msg5814070 I hack the hell out of this stuff.

I am not an electronics guru. I am a merely man with some soldering equipment and a willingness to injure myself and damage sensitive electronic equipment. So pardon me if this is a silly question... Am I to take it that by replacing the resistors per this chart we can increase the voltage and thus reach the hash rates beyond the published overclockable speed? (Which would presumably require increasing the ability of the U1 to dissipate heat.) src: https://github.com/AntMiner/AntGen1/blob/master/manual/AntMiner-U1%20user%20guide.pdfI am having a hard time believing it would be that easy but the ASICMINER upgrades were (after a huge thread of experiments by many talented individuals https://bitcointalk.org/index.php?topic=241652.0) The Antminer U2 does not appear to have the same resistor configuration. Has anyone looked into what would be required to increase the voltage?

They do, but they seem to have OC issues at anything higher than 2.4Ghash. Seems to be a voltage issue.
