went from 138GH/s to 145GH/s with my Mercury with 0.98.1

However I did not apply the all cores enabled bin. Should I? I never have before.

The max is 144 GH theoretically. With all cores running.

As for Slush and stats, my merc shows same there as everywhere else except Eligus which is all over the place. 141 /142 pretty solid since .98.
Not messing with it for a GH when you consider the downtime alone costs you money as it takes time to build back up.
Every time you shut down your average drops for a fair time period, hardly worth keeping doing it given the time sensitive period we're in now re difficulty increases. Your hashpower is worth much more now than after the next diff increase. I wouldn't waste any by messing about when the gains are marginal at best and possibly non existent.

Congrats Phoenix! I am at USD break even in one more day!  I've made 32 BTC with my jup.  One more month(ish) to break even in BTC terms using the exponential difficulty estimates I have been using.

Edit - Looks like I am USD break even today based on coinbase price.
chrono, when did you receive your miner?

October 4th

chrono, I suppose your miner minted @530-550 since the beginning right?

Yes - Around 520 gh/s from the start.  I got really lucky with a unit with around 4 bad cores.

I wonder if those that had an easier transport had less hardware issues? I picked mine up in Sweden and flew home with it, and yes although it did go in the hold and suffer the horrors of Norway Air baggage handling and had all 4 fans fall off, it may have had less of a traumatic journey than via UPS/DHL van. Because mine has been happy on .96 hashing at 555Gh/s with zero bad cores according to:


My theory is simply that the boxes they ship the units in are "junk" and the unit is so light that whowever ships it tosses it about..it is not like it says 'fragile" or "electronics" on the outside or anything..

Just to be clear my Jupiter IMHO runs really well with only a couple cores iffy (off/on) is probably DUE TO the fact they shipped in such shabby packages.....my theory is that my unit (if it happened at the beginning of the trip) the box was shredded to the extent the only way to keep the miner in the box was basically to use '2 hands" and carry it..thus no tossing about on the  trip...(although it did arrive in a soggy box that you could not pick up with 1 hand and could see mostly shiny miner inside.and the fact the miner was filled with at least a 1/2 glass of rainwater)....


anyway works well on .95 have not touched it..but it is uncalled for these units should at least be in the kinda box you get a cheap DVD machine in..ie ....heavy cardboard etc...there is no excuse...but anyway that is my theory "ass backwards" though it may be on why the only thing I have wrong with it is they did not include 3 of the 4 foam rubber dealie things  on the top of the heat sinks...(the bas*t*rds).....ship them from Sweden immediately I want the 3 pieces for foam rubber they owe me... Smiley

anyway.....but I mean really the cheapness of the shipping boxes they use is just plain scary

Think formula one pit stops.

I like that analogy:).  But lets do the math. I dont have a KnC, but how much downtime is there when installing a new firmware and rebooting? Surely less than a minute?

To win back one minute of downtime during the following day, all you would need is a 0.07% performance boost.

Used to be about 540-560GH/s on my hosted Jup. Now after the latest update, seems to now dropped to 490-500GH/s.

Kinda shitty. Needs for a way to opt in or out of firmware updates. They just seem to mass apply it to all hosted miners.

Same to us, they where running stabil with 540GH/s now since two weeks they hardly Run with 480....

Changing a wheel takes 2-3 seconds on F1, yet they lose more like 20 because like these rigs they don't instantly resume their previous speed right away. It's a fair old loss on the pool average especially if you keep doing it or worse, if it results in a lower hashrate (which you won't be sure of for an hour or so)  and you need to revert. Some people have had massive negative results from firmware updates to date, dunno why some and not others, but that required more pissing about and lost hashing.

An hour to get fully back to where you were isn't unusual in my experience when you reboot cgminer/ update. It doesn't go 100% - 0% for a minute - 100% at all, those last few GH can take a while.

Like F1 I think it's better to not have stops you don't have a clear benefit from.

0.98 works better for me than 98.1

I see there is a lot of people how stuck with firmware upgrades. I write it how I do because I never had a problem after upgrading.

1. ssh to the miner

2. shut down cgminer.

3. run enablecores

4. click reboot

5. ssh into the miner

6. shut down cgminer

7. make the upgrade

8. I never click on reboot, just shut down the miner, wait a minute

9. turn on the miner

10. go to ugprade page -> ctrl+f5

11. if you like install bertmod.

Hope it helps for someone.

One sentence about cooling.

I made a fuckin good cooling for the jupiter, I could cool it down until 26-28C on max load verey time. But Phoenix has right, these boxes runs better warm. For me not 70C but between 45-55C. Less hw and a bit better hash.

Anyone out there with a 4 VRM Day 2 order?  Just curious what firmware are you running?

I take it I don't need to run enablecores if I don't have any cores disabled (in bertmod)?

The only time I had to run enablecores was when I upgraded to 0.98 and cgminer kept turning cores on and off all the time until I dropped down to 450GH/s

The reason why I went back to 0.96 is that a) it gave me 555+Gh/s steady again and b) my cores stay enabled all the time.

Dunno if maybe the higher voltage of the later firmwares cause problems with my Jupiter or if its that cgminer is too eager to disable stuff.

Whenever I run bertmod on my Jupiter it shows all cores enabled and steady voltage and watts across all VRM's

I'll try 0.98.1, I always try the latest

8. I never click on reboot, just shut down the miner, wait a minute


do you mean just executing reboot cmd?

when u click reboot on the web interface reboot.safe will be executed instead

Code:
#!/bin/sh
i2cset -y 1 0x24 0xb 0x6b
i2cset -y 1 0x24 0x16 0
reboot

i really don't know which kind of settings i2cset cmds are performing, but my gut says that they should be useful, what do you think?

Yes I would have thought if you don't reboot after the firmware upgrade then the firmware isn't actually installed, yes maybe cgminer gets updated but nothing else.

I'm trying Firmware 0.98.1

Just to check, after installing it the Upgrade page still reports:
Current firmware revision: 0.98

Did they forget to change the version number reported?  Or did I not install it right?

Sorry guys but I'm not a linux expert....

There's a link after the upgrade proces "click to reboot"

I've tried it a few times but I'm alwas had bad hasrates. So after the upgrade I don't click it just shut down the power then turn it back on...

Exactly, so effectively as you are not running the proper reboot command it might not be updating the firmware, probably a good thing in your case, you are just getting the updated miner.

Hmm.. I think I might try it Smiley

Two firmware updates for me so far. Didn't do that, bot even half of it. Not had a problem

1. DL the update
2. On the KNC miner interface click update and select that download and apply it.
3. Click restart cg miner in the KNC interface.

Nothng else at all. Checked it after in Putty, but all was fine. lol
