OUCH! BTCGuild is down fluctuating, how do we apply a failover pool to these rigs?

This seems to be what I'm pulling on stock Hash Rate on Mercury does this look good for WU?...right now it's 139GH 2020 WU

Also, I'm curious to know if dropping the stock fan helped at all in terms of hashrate?

please use width property in img tags, thanks.

Hi trepex as usual great info shared here if you don't mind you could share also your modified ASCII version of asic_test.pl?

I've noticed you did change fans for the internal heatsink and that the new one are positioned lower than the original, did you considered the DPoS way?


anyway did you notice any increase in hashrate due to lower temp?

Great work trepex, thanks for sharing your mods and temperatures.

what is the deal with KNC running Flushwork?

my GH/s rate drops by 100GH when it performs this task... and takes a while to build back up to previous rate

I just did some port forwarding on my router.  Now i can access my KNC page from my cell phone when I'm out to check on it,update or reset, Also set up JuiceSSH app on my android.  So now i can connect to cgminer through ssh on the phone as well.

Yeah, great idea!
(Don't do it in an earthquake region!)

Here is my setup. I removed that external case for the fans.
The results are great. The BertMod (modified ASCII script) reported temperatures dropped by 4-5C:

Old setup (with two additional fans on the side, one on top):
Board 0: Temperature sensor: 40.5C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK
Board 3: Temperature sensor: 40.5C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK

Modified Board 3 (the right one looking from the BBB):
Board 0: Temperature sensor: 41.0C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK
Board 3: Temperature sensor: 37.5C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK

Modified Board 0 as well and waited 10 minutes:
Board 0: Temperature sensor: 36.5C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK
Board 3: Temperature sensor: 36.0C
 DIE 0 ON: 48 OFF: 0  100% OK
 DIE 1 ON: 48 OFF: 0  100% OK
 DIE 2 ON: 48 OFF: 0  100% OK
 DIE 3 ON: 48 OFF: 0  100% OK

This setup also cools the VRMs much better. I had two ones (same location, see picture!) with a temperature of
51-52C. Those are now at about 47C. The only side effect is, that the heatsink is getting warmer. But - it's designed
for that. See the infrared thermometer measurements on the picture.





No temperature reading for the 4th VRM, sorry!

Update: I just noticed that the power usage did go up from about 278W to 282W. Maybe it's running faster  

trepex

i have jupiter with 4 boards number 1 all
4vrms
but the speed with 0.96 firmware is 530gh only

does anyone know what to do to have more hashing like 550 gh?

DPoS I'm really glad that you're able to sort that out, so now your "faulty" jupiter is not faulty anymore

Let me just do a quick recap:

0) someway u were able to set input voltage for you miner to 0.9V
1) u've tweaked the cgimner.conf fiel in such way that cgminer start but do nothing (so no enable/siable core dance anymore)
2) run enablecore repeatedly trying to maximize the number of working cores.  
3) use Like-jr bfgminer instead of cgminer to mine

is this right?

a few other quests:

a) is this jup a 8 VRM  or a 4 VRM one?
b) which is the version firmware currently used on that box?
c) wattage at the wall?
d) u get a die completely turned off on one of your asic board, right?

thanks for sharing your experience.


edit1: theoretically with a 1200W CPU we could turn a good miner into a super miner using this procedure?
edit2: do you have lower system load while using bfgminer (uptime command output)?

Well considering i am  6XXX order and a mercury i got a feeling i will be having to wait awhile. Unless someone wants to buy it for me at my cost of buying it. Order price: $ 1,995.00 Shipping price: $ 102.60(One day shipping) Total price: $ 2,097.60

can use John.k or DannyHamilton for escrow at your expence.

I've already got my November-Jupiter refunded.
Still sitting out on the hosted 39xx Saturn (will give them one more week or so before asking for a refund), though people after me in the queue started receiving their miners. My hope is that Saturn can be later upgraded to gen2 Jupiter (sometime close to the end of the 6-month hosting period) and shipped to me.

If that is 30 days from end of september, then that wont be much of a pause.

Your matter is not reading/adding to a conversation which you are not aware of - i took them off, they didnt fall off...Thx.

@ Puppet - Thanks!! Sorted!

@Tolip - BtcOwaffle says lots of things - about 15% of which turn out to be factual

Bitcoinorama has said in this thread something to the effect,
there will be a 30 day pause between the first batch and the November orders.
(he was passing along KnCMiner statement from Sam I think)

This makes sense from a 1st batch persons perspective because the price drop was supposedly for orders shipping 30 days after the last Oct miner.

If they screw all the early adopters any harder the pushback will be unreal.
This will infuriate November order folks as all 1st batch have not shipped yet and it is Oct 23rd.

Shit storm no matter what they do.

My guess is they will do whatever benifits KnCMiner the most regardless of the effect on customers.
This pattern is well established by now.

They are unlikely to ship Nov. before Nov. 15 IMneverHO

YMMV

Hah, I dug that exact same socket set out of my toolbox to open the case and put the fans back on.Great they used those goofball screws and then used fans that fall off in transit. Or maybe that's just the standard screw everyone uses in Sweden.

I seriously hate UPS. One of my orders was given to a neighbour (again) and this time I do not even know the name. There was no notice whatsoever telling me where that neighbour lives... And now I can't even start a lost package claim because they think KNC is responsible for the shipment order. Great -.-. My DHL Order came without problems DIRECTLY to me. I seriously do NOT understand UPS. Why the heck would they give stuff to people who don't even live in the same house/street...

Gives me an excuse to share some pictures of a Jupiter I helped set up yesterday.

All fans on when delivered (hurrah).

Just fan fell off what the matter
