Hello,
I am thinking of overclocking my S7 B6 (4,05TH/s) a bit. Is there a special thread for OC of S7?
If not, what can you recommend? It runs at 41°C while hashing at a Frequency of 600.
Thank you and kind regards

It's not the temp that is more important, but The HW error.
I've got almost no error at 600 (less than 0.0001%),
so I overclocked it to 650: ~4.28-4.3 Th, 1160W, 0.0012% error
I noticed that fan never exceeds 4320; they probably capped it there.
675 and 700 mhz does not work (for my S7 B6)

You should overclock to a frequency where you get > 0.001 % AND < 0.005 % HW error. (between 0.001% and 0.005%)
This will allow you to get the best hashrate for your voltage.

I noticed that everytime bitcoin prices go high, the bitmaintech.com website goes down with an error 503. It happens too often to be a coincidence. Last time it happened about a week ago when the price went up to 430. It came back when it dropped down to around 420, but now it's 440 and it's down.

Are they doing this to prevent people from buying with bitcoins?

Also how fast are the newest batch? I know the advertised speeds are not the same as reality.

Ex: My Spoondoolies are advertised as 1.7 TH and 1.5 TH, but in reality I get 1.55 TH and 1.33 TH (120v and intake thermal says 20-23 C

Just out of interest, why bother with the EVGA and not just take the power supply offered by Bitmaintech?

EVGA can be plug into 120v, the bitmain psu cannot. Some of us dont have any 240v available. Wink

Yep, Believe it or not in the United States 240V is pretty hard to come by. Were talking dryer and washing machine plugs only. Maybe the oven if you want to go that far. I had the oven socket wired up to a PDU and wired up to miners a year ago but the other people in my house couldn't handle switching out to use the oven and all the fuss so we took that option away. If they only knew that the extra 50A/10,000Kwh could have been so much better for our mining over the last year...

Try explaining why you need the oven hooked up 95% of the time for mining/noise pollution to your roommates. I even offered to pay 100% of the electric bill. Roll Eyes

For some folks, the Bitmain PSU is a non-starter, as it requires a minimum of 208V to start. Hence you can't mine with a 120V (nominal) electrical circuit if you use the Bitmain PSU.

Obviously cost, if you already have an EVGA that can be re-used for the S7.

If you are starting from scratch, there are probably better choices than the EVGA power supply, the Bitmain PSU being one of them.

Now the money is free, and so the people will be

Get a single rail PSU if you go ATX, 1600w evga is the best. Batch 8 seems to pull a little more than 1300w....maybe underclock and get evga 1300w. Also with the 1300w you dont have enough pci cables, so its gonna be 2x per blade...1600w you have more than enough.

edit: Lepa has multiple rails and only 6 slots for pci cables...now with the double cables you get 10 total but I dont think plugging a double ended cable is a good idea. maybe someone could chip in on this.

You have exact model ? Enermax lepa g1600w ?

I have 1x EVGA 1300w, 2x Raidmax 1000W, 1x Corsair 1000W I never had any trouble with them.

Label a shit how you want, it's still shit, but mine had no Enermax in the description.
I have this

Sold as Lepa G1600 and refunded as Lepa G1600.

what do you guys think about the enermax lepa g1600w ?
is it good and reliable to run an S7 with it ?

thank you !

My advice, do not buy it.

I have them 4pcs refunded from warranty. Stil left 2 used.
You need single rail psu, not modular.

yes re EVGA 1300 G2 on most S7, not 100% sure re batch 8 yet since it goes to 1293W at default 700mhz.
check the fact that johnny guru reports 12.15-12.24 V even at heavvy load in hot environment (I was wondering why it works so good):

According to JonnyGuru, this would be a decent PSU.

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=283

However its expensive and you don't really need 1600w since you're going to be running it at around 12v. I'd go for a EVGA G2 1300. Cheaper. Rock solid and 10 years warranty.

wouldn't a 1300W PSU be overloaded running a 1300W S7 24/24 Huh

I'd rather have an PSU loaded at about 80 % than being overloaded

That's INSANE! ROI NO MORE!!!

Sorry, couldn't resist. I'm watching this for a while now, the times of 0.25J/GH are long over. Where's the S8 with 0.1J/GH? Keep em coming. Don't buy S7 no more, you clearly loose!

clgrissom3,
I'm having a beer now to celebrate your block find. Amazing to have 2 blocks found back to back by guys with 20 THS. cheers bud!

My first block ever...I hope everyone hits one!

Well, Details: Your Hashrate, How long you have been with Kano.is, Do you get the whole block, What is the pool charge?

Oh, by the way, Congrats!

My average Hashrate is about 21.75 THs (4 S7's and 2 S5's) and I've had my account since September to test/sample the pool. I finally went all-in in November. No, I got my share just like everyone else...finding a block gets you acclaim and bragging rights. Cheesy

It's just one of those cool things that matters on the Kano.is pool...getting your worker name listed on the acclaim board is like saying I've arrived. I think the pool is 0.9% PPLNS but the payouts are way better than I ever got with the Antpool, f2Pool, or Slush...especially on those double block days!
