My modified USB extension lead that I had patched 5V into burnt up Yesterday, so ran overnight on the 2nd Compac at 200MHz. Have just done a better job of connecting the 5V directly to the contacts on the USB socket so should be ok this time.
Good news is that the improved 5V supply seems to be allowing operation at 400MHz without HW errors with a Core Voltage of 0.78V which is the max I can get to without changing a resistor. So will run at that for 24Hrs and see how we go?

Well things seem quite stable after a few Hours at 400MHz so I have pushed on to 425MHz, still at 0.77V core voltage and no HW errors. I briefly tried 450MHz but the Core Voltage died completely so that needs to be investigated.
Rich
Great news, Rich Rich
!!!Thx for sharing!

For that you should search the support thread
No heatsink at the back (although I have some).
I've never tried over 310Mhs.
I've not tried more since I got the new heatsinks.
I'll probably give it a try at some point, but so far i'm quite happy
Ahh okay I've never tried over 310Mhs.

I'll probably give it a try at some point, but so far i'm quite happy
But I´m very curious, to know, where is the max possible limit

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

Hey zOU,
nice, looks really, really great
!Two questions about
: Did you also use heatsinks on every backside?
And what was your maximum (stable) Freq / Hashrate you ever reached with this setup?
Thx,
andY
Thx, but I'm far from Jeff's record
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!

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.
.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
.andY
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 Hey andy, can you say how much energy do you have to put into the peltier element? Is this power efficient?

!@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"

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.
Rich
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.
So I think maybe it could be a reason for your prob, if you got at last only 2.1A...
andY
andY
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?
Rich
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...
