Pair of s-9s now running photos are up.

anyone using other than the Bitmain's PSU (I recycled one of the S7 Bitmain PSU for the S9)?

I am reading another thread that using a EVGA PSU resulted better stability on the S9.

Granted that every PSU is a different quality (ie GOLD/PLATINUM, etc), power output should be decent enough if it can power up the S7. Are they any other difference?

well the evga platinum 1600p2  = $$ 350-375 usd

the titanium 1600t2 = $$$ 399-425 usd

but I have a suspicion that the bitmaintech psu is not quite good enough to run these units.

[Erumara]

I finally found the video!

The eVGA units are certainly more expensive, but well worth the 10yr warranty. I had one crap out after two months and they shipped me out a brand new unit, in box with full warranty, in 48hrs. As the video shows, they are demonstrably more efficient than the Bitmain units, and if someone is claiming they are more stable I would not hesitate to make the switch.

philip, in your other post at kano..... 1800w PSU? really? EVGA doesnt have that, so we need to explore the IBM/DELL/HP server ones?

my two use these two of these

http://www.ebay.com/itm/IBM-Delta-Electronics-BladeCenter-DPS-2000BB-A-Power-Supply-39Y7359-24R2710-/222128625016?

 and I can get 13.9th  but since it is in a hotter place  I run a bit too hot and I  downclocked

http://www.ebay.com/itm/IBM-BladeCenter-1800W-Power-Supply-P-N-74P4400-FRU-P-N-74P4401-DPS-1600BB-/252423855278?

I ordered this it can do 147.5 amps at 12.2 volts = 1799.5 watts

it is cheap I have a board the works on the dps-2000bb  maybe it works on this one.
if not I will order a dps-2000bb

with the BM-PSU I recycled from the S7 pushes the S9 to 13.6THs atm.

if your dps-2000bb can push 13.9THs, I think the 0.3THs additional hash may not be cost efficient in my case @ 650mhz

I am going to test a EVGA-G2-1600w next on the S9 and see if it has any difference or improvements.

Edit: I may keep this unit since it doesnt have the wooo sound, and the other units will go straight to the hosted place.

so 13950/14000 =  0.9964   or 0.0036  and your errors are 0.0004  at freq 650

please humor me as you have a really well preforming machine  could you set it at  freq 643.75 vs 650?

I have seen s-7 and s-5 run at 0.0000 error rates with tiny underclock.  If you gear were to do this you may get 13950 hash with 0.0000 and save a tiny bit of power.  other then that your machine seems to be a top notch batch 1 machine.

I decided to try o/c first  656.25 and 662.5 were not promising, but 668.75 has run for 1hr with only 3hw!

Avg. - 14.26

I'll post screen image after ~4 hours. This is with PCB @62/62/64 and die 94/91/97

PSU is DPS-2000BB w/ default voltage. Will be measuring efficiency and trying different input voltages soon.

Do be aware that the DPS2k does not have its own fans... What I did for running 3 s5's off of one is put the PSU about an inch away from the intakes of the miners.:

I wonder if that would alter the s-9 whistle sound?

My next two batch 2's should arrive soon although still not shipped.

Stupid of them to not offer batch 2's a fast track payment  I would have sent them the 200 extra to have them shipped on the 15th and not the 20th well thats 200 they lost.

I bet hundreds of batch 2 payers would have kicked in more money to quicken the batch 2 shipments.

I figure bitmaintech lost 20,000 by not offering that to the batch two purchases.

I hate to be the manager that did not think of that his boss will be annoyed to see all that money left on the table.

[NotFuzzyWarm]

Yes, it does alter the sound. I was testing my s9 at work and using one of my DPS to power it. While moving it around I found that changing the airflow at the s9 fan intake changed the pitch/sound. Didn't have to restrict the flow, just change it. Then stuck some foam air filter in front of the fan and no more siren.

That extra money they could have made for a fast-track delivery is why I think something went wonky in their parts supply/production schedules with the line/subcontractor doing the b3's finishing first. Sticking strictly to parts allocation and per-batch tagging of sales led to the flub.

I had two batch twos on order to not offer me the option to send in 200 for fast track was dumb.

I am sure many batch two buyers would have sent in 100 more.

Okay - Here is 14hrs @668.75; Avg. 14.28

[citronick]

S9 still running her legs on kano, solo.ckpool and zpool/sha256 via APAC MRR relay.

I manage the pools at MRR portal for ease of use.

I am ok with 13.7THs at stock clock.

Yes, the temps needs a bit more cooling but can someone explain to me the HW errors across all boards?

PSU used is the one that came with S7.

Many have advised me to test using a EVGA-1600w to stabilize the HW errors but I am thinking why?

Is Bitmain's PSU that bad to cause HW errors?

[philipma1957]

the number of hardware errors means nothing  the % does  0.0019  means 99.81 % are good.

but as  a suggestion clock at 643.75 for a day

[firetreeactual]

I have to tear down and re-vamp my racks here at home (in the living room) here today, and will try hard to get some pics of the rig I put together to manage the heat and noise from the S7s I had here (which are now at or enroute to Labrador). I'm now just running the six S3s in the same package, but I think the method may help some folks. They'd still be here if I hadn't run out of amps (I can manage running six S3s, but not three S7s). From what I'm gathering it might be helpful for someone.

I've never used MRR but I'm curious. Do you just use MRR for pool management, or do you actually rent out your rigs? Maybe you've configured a high profitability requirement so that they're never rented?

I see that you've configured all of your pools to be MRR instances. I'd be concerned if all of the MRR servers went off line, or if they were hit with a denial of service attack. Maybe the last failover pool URL should be a different pool.

You're right.
I use MRR for pool management. The 3rd pool can be pointed to another non-MRR relay pool, ie. SG kano node.
In MRR, you can choose "Unavailable" resulting offline for your rented rigs so that it would not appear in the rigs for rental.
I have run this by kano and -ck, and no issues. Using MRR relay nodes just basically gave me a few more other ways to connect to main kano pool and some ease of management when I swing to other pools like solo.ckpool.org or other SHA256 pools without touching the S9 menus.

Good find.  I could use something like that for one of my rigs with the thermostat rather than having the box fan run 24/7

I had to order 2 to get free shipping.  I think we may need 2 of  them for the four miners any way.
