Topic: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH &amp; 0.51W/GH - page 165. (Read 451277 times)

I received my S5 today and I'm having trouble getting it to hash.

Sometimes it will hash at around 650 Ghash/s for about 5 minutes and then it will be hashing at under 1 Ghash/s for most of the time.

Am I doing something wrong?

What are you using for a PSU?

Can you upload a screenshot of the status page please? What is the exact made and model of the PSU you are using?

It's an Artic Blue 850W, model no. AD-E850AE-A6 (I think) it actually seems to be working fine at 300M at mostly 900 to 1000 Ghash/s, had it going for a good while. Can't get screenshot right now as it's switched off for the night.

Its more than likely your PSU's fault as its quad rail, and I can't find ONE piece of information on the distribution of its power across those rails.

That's why I asked him the question. Almost every time that this issue comes up it can be traced to the PSU used. I had never heard of that one before.

PSU Ratings: +3.3V = 24A +5V = 30A +12V1 = 34A +12V2 = 34A +12V3 = 34A +12V4 = 34A -12V = 0.5A +5VSB = 3.0A

multi-rail power supplies suck. this one has 4 rails, each with a max rating of ~380W. depending how you plug your miner to it, you could easily be placing the entire load on only one rail and thus it trips

So.. I've tried to search this, but I haven't seen anything on it. I have a new S5. It seems to run fine. Every once in awhile, though, maybe every day or two, I will see that it is running at half efficiency.. in the 500-600 GH/s rate. I go into to miner configuration and hit save and apply without changing the settings.. and it goes back to 1150-1200 GH/s. Sometimes it stays for a day or so.. sometimes it stays for an hour. Is this a faulty power supply or a firmware glitch..? Anyone else seeing this happen?

Quote from: Songminer on January 15, 2015, 09:50:42 AM

I'm seeing the same thing on my 1 S5. Frustrating. Sometimes a save and apply click in the configuration page works for a full day or two. Sometimes only a half hour.

Hoping there's a firmware fix coming to fix this. In the mean time is there any provision for a periodic reboot built in?

Yes, its a known issue and will get fixed soon^TM. Current solutions are timers on the PSU to hard reboot [harsh], or software monitor's like M's to issue soft reboots on hashrate drop. Soft reboots won't always fix it depending on which exact issue you get though.

Has this been fixed?

The major causes were fixed in the January firmware update but there may be some rarer ones still about. A lot of them are PSU based as every unit has a different definition as to what it considers 12V, which further varies on PSU load. That's not something that can be fixed with firmware updates.

@opentoe:

I have the Corsair SP120's in push/pull, and I can say these are definitely not ideal, as they can only keep temperatures in the low 60's when the S5 is downclocked to about 325, for an ambient temperature of about 16.

Note: The Noctua NF-F12 2000, has higher airflow, higher static pressure, at lower rpm's, and lower noise. It is simply a much better fan than the Corsair, period. They do not come cheap though. Cheesy

SP120s benefit from taping the top and bottom of the heatsinks shut, it improves their performance markedly.
