Something strange happened while overclocking today. I forgot to put the # in front of the 350. So I had both 375 and 350 running at the same time. When I first rebooted the miner, for a couple of minutes it was running at 532Ghs, I should have took a screen shot. It finally came down to 400, then 300 and around 210. I was having no HW pop at all, and it was still running at 350. Any thoughts about this. If i continued with both of them, would I damage chips? Thanks in advance..
the averaging system can report strangely at times, espescially during the first 10-15 minutes. Ive seen 800GH in the 5s and 300GH average before at about 15min into use, but the pool was 200GH. it quickly/eventually settled to a correct average

After logging in via SSH the following steps: 1. type: "cd /etc/config"(without the quotes) and hit enter. 2. type: "vim asic-freq"(without the quotes) and hit enter. 3. hit I button to enable "edit mode" and adjust the settings, lines beginning with # are ignored. 4. after you're done hit the ESC button to exit "edit mode". 5. type ":wq" (without the quotes) to execute write and quit. 6. you'll be back in the command line, type reboot to restart your device. You can check your frequency in the web interface miner status page. If everything went ok, you're mining with higher speed Then you can donate to me for providing you with extra steps to unleash ultimate hashing power 15j3fDzunHtoTsDH7MAKQQiG95q5yWYTfk Keep looking at your HW errors to make sure your device isn't frying up. I've added some tiny heatsinks, and running 400Mhz but still 3.3% HW error. But my Antminer is using the Corsair AX860 80+ Platinum PSU and @400Mhz it's sucking around 395W out of the wall-socket Complete newbie question, but when you say login to ssh, is that just logging into the Antminer? Where can I find the area that enables me to modify the scripts~? Many thanks for your help gents & ladies

Great overclocking video vvhiteknight. Thank you. I'll send you a donation later on today (in LTC, too cheap for BTC )

Im gonna go out on a limb and say its impossible to *damage* the chips w/ incorrect frequency settings. I know it can cause the clock gen to hang, depending on the incorrect setting, and require a power cycle *happened to me*.... but since we are just messing w/ clock gen and not voltage control....I doubt its possible to do long term damage via just clock settings.

Sorry guys for the late response Had a very busy work period and got not much time to play with the miners not look at the tweaks of them Have added the various options and started slowly test some of them You guys was ofcourse right with the either the freq file not being correct or that the cooling was It was the cooling the minute i took the blue wire from the connector they started blowing like an idiot Which made a instant cooldown from 45 C to 29 C The 387.5 was giving me a instant boost from 175 Gh to almost 195 Gh so i let the machine run with it. But its somewhat early to tell the initial results are nice However when i changed the values to the 393 settings the miner started to run slower. And the hw value goes up quick. The same applies to the 400 setting, again i tested only shortly. But in a few minutes both settings result in more hw errors and slower hash. Before someone says its your psu .... i am sure its a very good one, it has feeded 3 x 7970 @ 1100 Mhz at litecoin mining with ease. This NZXT hale 90 - 80+ Gold - 1000 watt, is not even start its fan to cool because its cold as ice. (added test connected my enermax 1350 watt and same results) Ofcourse the winter temps here to be near freezing and at some moments below -2 C help as well [LAZY MODE] ON How can i get the stats of the antminers onto a monitoring program like bamt had or something similar And can scp be installed on these, so i can winscp into them from work as well [LAZY MODE] OFF

Thanks for the reply. That's good to know. I have 3 miners now overclocked. Each miner is truly different. I'm running them at 375M: Antminer1 1816 3155840 3072 0.0575% Antminer2 10 3132010 4379 0.0003% Antminer3 1247 486225 869 0.2554% I'm thinking about kicking #2 up to 400 just because of the extremely low HWI. I wish the other's were like that.

The 2 boxes are running for 2 hours at 387 Mhz and result is
Gh. avg Accepted HW utility discarded localwork wu Temp
Box1 196 24,941 3,102 175 506 455,826 2,801 30, 31
Box2 198 31,570 58 173 630 584,426 2,782 31, 31
Anyone know what the red led means which starts burning after several hours mining ?

I had this happen overnight as well on one of mine. Temp on mine is 42 & 43 and it is sitting in an aircon server room. Unit is definitely hashing away on 400 setting (202Gh/s) and pool reporting continual hashing data, so xxxx must be bogus in some way, or at least does not prove unit has stopped.
I will join this club. Woke this morning to: xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx Shut it down and let it sit for 5 minutes. Now back to: oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo (at least for the moment...) S1 had been running for >4 days constant. I do not have them very long but i see them showing those each day, after reboot all seem ok. but during a day they slowly change all into the x .... When i reboot them they are back to o, the nasty part is they are only a few days in my posession. Even changed the psu from 850w corsair to nzxt 1000w and my 1350w one. Seems to keep coming back, not sure if the fix on the fan will help will see that tommorow. Crossing fingers that will do the trick

Mine switches back and forth between all "o" and all "x". I just let it keep running without reboot, it eventually cycles back to the other one. (so far )

Confirmed, using 375 MHz and 37 timeout is hashing at about 200 Ghash/s option 'freq_value' '4e81' #375M option 'chip_freq' '375' option 'timeout' '37'
At 400 Mhz, I got way too many hardware errors, like 50%...so, I'm trying the 375 settings. Dunno why that was so high errors, but I guess it's just the luck of the draw.

I wonder just out of curiosity, has anyone tried underclocking to 200 to see if it really hits anywhere near the claimed 0.68 J/GH on chip? Might become useful a few months from now when difficulty reaches the moon.

best psu to use is the ax860 for 2 antminers.

You'd also have to change out 8 resistors to lower the voltage to the chips.

Well I'm over here fine tuning this clock speed here are the results after a 12 hours of running:
Antminer1 5586 1915520 2176 0.2904% 387M 195G Antminer2 10242 1914541 3058 0.5313% 387M 195G Antminer3 4529 1785578 1498 0.2528% 375M 191G
I'm getting a consistent 581 from the 3 of them. When I try and go higher the errors get crazy. I feel comfortable at these numbers. The temps are in that 44C range. I was thinking about taking two of them to 393, but I think I'm going to leave it here for now. Curious as to you all's thoughts about these numbers. Good, bad, can be pushed more?
Thanks.

Those of you running at 387.5 MHz,
Which hex code are you using? I re-read through this thread and found "5e82" and "5E85" What timeout are you using? How much power are you drawing?
Thanks.
