with 201 i have 615-620 Gh/s, with 211 i have 586 Gh/s, and with high temperatures (76º) i have 597 Gh/s is that normal?

No no
If see my post I have problem can help me to fix it

The student becomes the teacher!

Well done!

at 0.99.2 firmware does not have these one
how will can do overclocked??




is at the command prompt:

vi /etc/init.d/cgminer.sh

Use the cursor keys on your keyboard to scroll down till you see this code:

Look for the line that says:

cmd=$(printf "0x86,0x%02X,0x01,0xF1" $c)


NOTE: some of the characters at the end (especially the F1) may be different.

The key is the line with the 0x86, when you see that you are on the right line.


change this:

cmd=$(printf "0x86,0x%02X,0x01,0xF1" $c)

to this:


cmd=$(printf "0x86,0x%02X,0x02,0x11" $c)

Ctrl+F5?

Hi,

I am using Oct Jupiter with 0.99.1-tune firmware. After I pressed "Reset factory settings" on Advanced tab, I can no longer access Advanced tab at all. Instead I have browser message with "Fetch advanced configuration/status failed." and "OK" button. Restarting, flashing to earlier firmware and flashing back to 0.99.1-tune does not resolved the issue. Jupiter itself is mining away nicely, but I can't access Advanced tab anymore.
Any one had similar problem?

Your temps, amp and watt please ? 

i run 231 on both 4 and 8 vrms modules both are fine

i run 231 on 4vrm and 211 on 8vrm(just started)

so, with my temps can i try "850.0 211" without much risks?

Anyone try this on a Nov Saturn? I think the Nov units are high clocked already so I'm not sure if I can squeeze out much more performance from them. My numbers look like this:

small update:

FW: 0.99.2-tune (oct)
OC: 231
Advanced tuning:
* SPI volt: default (1.95)
* SPI freq: default (201442)
* die voltage:


After OC:
Avg.HR: 660 Gh/s, poolside: 650 Gh/s
WU: 9246
HW err%: 2,6%
Watts: +- 700 W (via advanced-page in 0.99.2)
ASIC1: 56.0 ℃ , avg 55 Amps
ASIC2: 43.0 ℃ , avg 54 Amps
ASIC3: 62.5 ℃ , avg 56 Amps (highest die: 62 Amps)
ASIC4: 52.5 ℃ , avg 55 Amps

tips for OC:
keep an eye on Amps per die (in Advanced-page) and aim for 50-55 Amps range per die.
Then change die-voltage accordingly (2-5 steps on max 2 die's at a time) -> save and restart cgminer
-> wait 2 min. for first impressions -> wait at least 10-15 min to see if performance stabilises! 
(if you OC too much, the first couple min u'll have great results, but after 10 min performance decreases fast)

nobody knows, or you get misleading info from 2 ppl from knc...hno said nothing over 50a is safe n bit..something said 64a is safe..so up to you on who ya believe and i have no idea on safe max temps...but as always the cooler the better

Just two questions:
a) max temps ? 70-75-80 Celsius?
b) max watt and amp ?

Thanks  ! 

Ok so my fault

i have a board running close to 80c just fine

Please do not post misleading information. 58 is anything but high temperature.

Your tempature is a little high

Put some extra cooling at Jupiter

This is the info of temp and volt's i have after OC

Is all fine?

Thank you very much for your help ncs0ne!!

got my 8vrm upto 600 - 610 and running BFG


done the exact same thing to my saturn 4VRM machine but no BFG ever??
