Got one of my Sticks running on my broken R1.

Taking it easy on the Frequency until I hook up a separate supply.

Well done, Rich !

Is anybody from EU here and wants to join gekkorun, but lacks on a GSC Stick ?

I can recommend the offical german reseller for germany and EU.

I´ve discussed with him the conditions, so he can offer free shipping EU wide (except Switzerland, Liechtenstein and Norway)

You can place there your order for 49,95€ (incl. Shipping & Handling)

Only what you have to do is, tell him my name (André)

I have bolted my Compac onto a CPU cooler, board above it is a fan Controller. I am connected direct to a PC running cgminer, just too many many problems controlling it from the R1,  and have spliced a separate 5V PSU into the feed so we are not current limited.



I have been running at 375MHz for 24 Hours now without problem, but get some HW errors at 400MHz so need to change the value of the series resistor on the Core Voltage pot as I have run out of adjustment and need to go above 0.75V to carry on up in frequency. Temperature is at the set 35 Deg C and there is fan speed in hand so that should not be a limiting factor.

Hey Rich, congrats !!
Looks really great !

Btw: I had the same ideas  , but just want to realise it later at weekend, cause just looking for taking my R1 to the limits  

Ahh, and the red USB- Volt/Amp-Meter I use too , but as far I know it´s limited to max 3 Amp, so it could be the prob maybe?

Yes the USB meter may be a problem, it's at 2.1A at the moment, however it's a nice to have item rather than essential, so can easily be taken out of circuit.

Hi Rich,
yes I agree , it´s a great little but useful tool !
I´ve used it for a "solar powered only" project for a Z3735F based Windows-PC last year
(...and it works great . )

But back to ther topic:
My R1 runs @475MHz stable with no (or very rare) HW errors @0.935V, but takes avg 34,45 Watts from the wall (excluding fans and peltier power).
That means, it takes nearly ~ 6,886A@5V.
So I think maybe it could be a reason for your prob, if you got at last only 2.1A...

We may be at crossed purposes here? By problem I meant that I might get to the limit of the USB meter? It's fine at the 2.1A being taken at 375MHz but may not at higher voltages / Frequencies?

However I have not tried above 400MHz yet as I began to see HW errors, so until I change the series resistor on the Voltage pot I cannot try any higher. I had planned on removing the USB meter anyway as I was worried about voltage drops in it's sense circuit & tracks etc.

Will probably give it a go Tomorrow, but have got to remind myself which resistor to change & what to?

Ahh, note sure maybe there is a misunderstanding
What I wanna say was, that the USB-Meter could be a limiter if you try to screw up the Vcore and the freq....

@Resistor/Pot: not sure, I have not checked it so far...
I guess it works in the same way like our Antrouter TPS53355 Mod?
So I think, you have only to put a extra 10k pulldown resistor from the pod to ground to increase the Vcore limit...
I´ll take a close look to it tomorrow...

I really like your mods 
Hey andy, can you say how much energy do you have to put into the peltier element? Is this power efficient?
Do you have to put more energy into the peltier than into the gekko?

Hi minibit, thanks  !

@Peltier:
yes, thats really an issue ...
The power consumption is depend on which kind of Peltier-Modul you use..
There are a couple of different sizes, Cooling/Heating power and prices on the market.

I´ve used the most available and inexpensive 40x40 Peltier with 12V and 6A max
It´s hard, ´cause  it´s finally a max. Powerconsumption of ~72 Watts, but as used in my setup and regulated via controller
my Powermeter shows me max ~ 50W for Peltier & Fan together.

But it was only a first try, there are smaller Peltier-Modules with lower consumption (and higher prices ) on the market.
Next step will be to try it with a more efficient Module...  

On the other side I have digged up an older project of me, where a miner could be completely supplied via a selfmade solarpower solution
So I´ll take an other R1 of me soon to upgrade this and give it a try for a "Green-IT nature-friendly mining solution"

Cool  
Yeah they look really expensive. Conrad has some, but maybe they are cheap quality?
So the cooling capacity of a peltier element is the difference between the hot and cool sites? Say, if my Peltier has a temperature diffeence of 60° C, that's the cooling capacity?
I'm new to peltier  

I like the idea of a mini solar array. For a single Gekko or R1 it's not that expensive. But the learning potential is huge.

@Cooling-Temp: Yes you´re right .
In a easy way you can say, it´s the max possible Temp difference between both module sides...

@Solar: ohh, thats not a big thing .
Not too much to learn for .
I´ll post asap the solution, pictures and HowTo´s...
If you´re interested in DIY, i´ll help you of course  .

here's my setup:

6 compac sticks in a BFL 30Ghs enclosure
3 sticks per heatsink
1 superbpag switch
1 fan controller + 2 temp sensors

I will probably remove the right hand side cover so I can slide the right fan further away, I'll add a wire grill

I like your custom heatsinks very much!

Oh man, you have a superbpag hub! I'm looking for such a hub for weeks now, but no shop will ship them to my country!
