so after 30hrs or so, here is where I am at with my Saturn on .95 firmware....should I update it to .96

miner_knc 233.65 GH/s 5534080 (99.82%) 7936 / 31616 / 2176

temps are 47 slot 1, and 40.5c slot 5

did you atleast do the enable cores ?? one thing .96 does that I see is it will hash a little slower than .95 but much less HW errors thus less cores going off which equals better output, but if you have cores that are always down might get more out of ,95 or .94 with auto restart script since usually those firmwares will let your miner drift to lower and lower avg

DPoS, if you notice in my stats, I have less than a 1% error rate, so I don't want to mess that up, but feel like 230GH/s for a Saturn is lower than what others are showing for their Saturns. phoenix1969 has 3 saturns churning at 275GH/s each...I would like at least 250, but not sure if its attainable. I have done nothing to the miner, not even enabling ssh, other than plug it in and run it....suggestions, ideas, and comments fully accepted, thanks ahead of time.

Can someone please explain how to see the cgminer outcome?? I use screen -r but it won't take me the process name like with bit fury. How do you see the outcome of that process?

Not sure if anyone has seen this or I'm late.

EnableCores (Use this patch to force all cores to enable at next reboot)

https://www.kncminer.com/pages/support

According to Bertmod, it enabled 1 last core on my Sat so all my cores are 100% working.

What's EnableCores for? What happens if I don't run that patch? I'm not sure I quite understand...aren't all chips/cores to be re-enabled on any reboot???

Thanks

that's the murky part we are trying to figure out

I'd like to know all the ways that a 'core' goes down. Why a whole die of 48 cores just shuts off. And also why some dies have 10-30 cores off all the time and then others that get 'cleaned up' easy and back to perfect

How do I see the cgminer mining details? All I know is how to access the web interface.... which doesn't provide actual hashing rate

Seems to contradict the findings of Afox. Perhaps some random variance?

BTW, does anyone know how to do p2pool with KNCminers? Any details on how that'd be achieved would be appreciated (especially on changes needed on the KNC miner itself, not so much so on what needs to be done in the host PC running the p2pool software).

KNC's don't work well with p2pool. The ridiculously slow flush work causes a lot of issues and around 150 Ghash loss on a Jupiter.

yeah that's what my post was about.. some core issues are 'easy fix' and .96 wipes them clean, while other core issues are 'your'e screwed!' and can't do much.

Enable cores is part of ,96 install. i guess they gave it out separate so you can run it with other firmware

Ah I see. When I upgraded to 0.96 I was wondering why when I downgraded back to 0.94 I had a few more cores enabled (from 41/48 to 47/48). But when I used the EnabledCores flash, it kicked the last core online.

But in the end, no hashrate or WU/m increase for me.

it seems they only test their firmwares on one machine before they release them., so much variance

I am getting great results from my one miner that was running .93 for a week ~520 and now is ~550

not all HW errors / cores failing are the same. Some miners will be a clean slate after .96 while others that have bigger issues won't squeeze the same performance out

tl;dr if you have a miner with above par components, use .96 (if you have 8 VRMs of course don't bother going past .94)

I do think 0.96 recovers from "flushwork" a tiny faster then the previous firmwares. No concrete proof though.

Could someone please summarize their findings with the last firmware versions? Something like these data points:

- Firmware version
- Power consumption
- Hashrate
- Temp
- Errors, etc/

I updated from 0.95 to 0.96 and I'm sad to say that I regret it.

Firmware 0.95
512 Gh/s (538 Gh/s avg on Eligius)
41-55 °C
5% HW errors

Firmware 0.96
476 - 518 Gh/s
41-55 °C
4-12% HW errors

Strange how 0.96 seems very unstable for me compared to 0.95. At first after I updated the hashrate was immediately down and had 10% HW errors. So I did a hard reset and after a reboot things seemed fine again with 4% HW errors and 518 Gh/s avg on cgminer, a tiny improvement over 0.95. Then after I restarted cgminer the hashrate started to suck again with a lot of errors. I tried rebooting but it seems to only get worse with 12% HW errors now and only 476 Gh/s avg. I guess I will go back to 0.95 and hopefully get the old stability back even though 5% errors still seems a bit too high. Sad

1hr result with firmware v0.9.5
Not much different at this time.

Does v0.9.5 improve or worsen power consumption at the wall?

I have yet to load v0.9.6, So I can't say at this time.

However in the next 36hours I will be able to definitively answer that question.

Here are the results after 4 hours on firmware v0.9.5 - Ambient Room Temp 20

Replaced Both KnC (Jupiter 1) and KnC3 (Jupiter 3) intake fans have been replaced with high CFM ones.

Those systems seem to have the poorest performance of the lot.

Results after 3 hours

I will be testing v0.9.6 soon. However My 3rd Jupiter restarted cgminer 6hrs into my test. I took steps to swap out the intake fans on Jupiter 3 as it performances similar to Jupiter 1. I hope this will solve the cgminer reset.

Do you have a Jupiter 2 then as well? Why did I suddenly think of 'Lost in Space'?

nice.
