Title: [AntMiner S1] High HW error
Post by: simon66 on March 26, 2014, 11:19:20 PM
Good afternoon all,

I recently purchased a brand new AntMiner S1 and got it work within minutes. I've never mined bitcoins with ASICs higher than 10Gh/s, so my "problem" could be normal.

I've been running my miner for about 5 days now and everything I do, doesn't seem to "fix" my issue.

I read a few posts where ppl said that they have 0 HW errors while running for about 2 weeks. Here are my screen shots:

As you can see, my HW errors are at 0.1%, which is alright. But I can't overclock it to 200Gh/s. I get like 5 accepted shares and over 5k of HW errors. This is the new 2014 antminer version.

Are my HW % good or can I improve it? Also, anyone with the 2014 model got they miners to hash at 200Gh/s?

Thanks!

Have you tried the 39x.xx Mhz speeds?

It is running a bit hot. If you can improve the cooling you should be able to run at a higher freq.

Your HW rate is probably ok.  To overclock you need to check if your power supply can cope.  You may try smaller steps rather than going directly to 200.  Other people reported that 375MHz (192 GH/s) is the 'sweet spot' before HW errors or partial thermal shutdown takes over (look at those ooo's in the ASIC status report, when these start changing to x's your miner stops some of the Asics).  There are good guides how to modify the configuration (see https://bitcointalk.org/index.php?topic=348327.40 (https://bitcointalk.org/index.php?topic=348327.40)).
As far as cooling goes - many people added a second fan at the other side, usually to 'pull' air out, while the original fan pushes it in.  I found that a 14cm fan did a better job than a 12cm one (connected a standard pc pwm case fan to the fan connector of the 2nd blade, it runs but without speed control or speed reporting).

Cheers

I also received one more for some days ago, I got many hw errors, it seems like that the fan not spin up as on my other two antes and not being cooled enough. The only thing I can see that differs is the cable for this fan comparing to the other two.

You do not think you have any questions S1 ​​in after you read my attachment, so what, I still got the 195G average speed.

I think first you must try small steps instead of going directly to 200. It would help you. You may also can check your power supply. Also you more can get information from this forum. You can use 14 cm fans instead of 12 cm.
