Ok. Second stick modified from pencil-mode (2.6 gh/s) to 9.1k resistor (2.4 gh/s)
both on bfgminer 3.2 w/o fan ;-)

I think there is some speed left we have to find .... maybe an 100k or 130k resistor on top of the 9.1k ?!

Have you got a fan you can try, to see if your error/reject performance improves with the cooling? What temperature is the chip running at?

[Atomar]

Our EE resoldered the 9.1k + 120k on top with something else.
I habe to ask him tomorow, what he did. Now it is only 1 restistor.

Somehow it was faster with the pencil mod the with the resistor ... hmmm

Now at home with both connected to the RaPi AND an USB fan blowing to it
the readings are:

2.482 gh/s (reject:1 / error 8.0%)
2.627 gh/s (reject:0 / error 9.6%)

But startet 30min ago.

Edit: Our EE put an 82k resistor in. Somehow strange how different the sticks react ...
After 12 hr strait mining with fan the sticks are NOT hot at all !! (can't messure the temp)
So we might replace the resistor on the slow stick again to gain Speed ... ;-)

so mine seem to be making a annoying high pitch noise while mining. Its kinda quiet, but can notice it at least.
is this normal? i have 7 of them.

Doesn't seem normal, my twelve are completely quiet.

I'm not really sure what to think of your remark to be honest... but maybe other folks have similar experiences?

Is it all of them or only one? Mine are silent.

PENCIL MOD +. Heatsink removed, swapped for a CPU hsf unit. measured at @ 29deg C
R15 = 0.85 (measured at 20k)
HW's = 9.89%
2.732GH/s (5s avg)

You happen to have a picture of this you can post>?

Any chance of a Picture yet?

[Atomar]

I think I'm to old to hear that high pitch noise ;-) But I would say, mine are quiet to.
Thinks the fan makes more noise ....

[Atomar]

OK. Done playing with resistors. Have to make some Money :-) I am "happy" with the result.

1 with 91k is minig with 2.622 Mh/s
1 with 72k is minig with 2.528 Mh/s

Operating only WITH fan now.

If I hold the a blue fury with the USB connector pointing up and look at the fury chip there are tags to the top, left and bottom that have solder loops joining some of the tags but no tags on the right hand side joined together. No blue fury that I have has the same set of tags joined by solder.

Can someone please confirm that the tags for the top, left and bottom are all joined together on the board and the tags make no difference?

The one that died on me had all the legs on the left hand side connected together...but then again it looks like they're all ground plane anyway.  It's death may or may not be related.

Any update on Bitminter miner support with these?  Would help us noobies out here. thx!

Sorry for the delay, I've edited my post above showing my mod to my test unit, let me know if it's any help.

Thanks for the info, I think that they are all joined together but it would be nice to know for certain although it does not seem to affect the operation.

Anyone else noticed that sometimes the LED's on the Blues just blink red on and off but sometimes they light up alternate yellow > orange > red and don't blink at all?

It doesn't make any difference to the hashing speed, just wondered why this was

I know in BGFMiner you can toggle an identify switch, which switches the miner from showing the yellow LED on or off, personally i prefer it off with a red flash for accepted work.

Where can I access the toggle?

Code:

[M]anage device
up/down arrows to the device in question
[I]dentify

this will toggle the light red to orange or vice versa

Thanks Taugeran! Seems like there are only two options on the Red Fury, red only or red and yellow indicators.

Just pencil-modded mine to about 0.85 MOhm getting 2.99 Ghps each.
Both sit in front of a big 120mm fan.

Is this okay or should I go lower in terms of Ghps?

Do you think this fan:

Would be enough to keep them cool with the pencil mod?

[Atomar]

I have the Desktop Fan from Arctic andboth mod sticks stay nice an cool.

Is a certain amount of hardware error acceptable? What actually happens when there is a hardware error? I'm using CGminer 3.8.2 on a Win 7 PC. All miners are directly connected to a USB port not using a hub. This is what I'm getting, speed don't seem to be that great too.
