So where on this gridseed do I find the measurement point for the voltage?

Just for the hell of it and since I couldn't sleep, I did the bridge mod, then wired up a 50k pot to the 36K resistor that corresponds to VID1 (Voltage = 1 parameter) and a 50K pot to the 33K which corresponds to VID0. Since I know someone may ask...I removed the stock resistors. I set them both to stock resistances and noticed some odd behavior. At 800Mhz it seemed that without the Voltage=1 parameter the pod would hash away, get no accepted shares, and accumulate hw errors. At the same 800Mhz speed using the voltage=1 parameter the pod would hash away, get accepted shares, and still accumulate some hw errors. Not as many as without the voltage=1 parameter, but still errors all the same.

It could be that my pod is just going to throw hw errors due to some damage when the mosfet blew...so someone else may need to give the idea a shot and see how it turns out.

*edit* - yep...even with the 2 50k pots set to the stock gridseed values of 33k and 36k, and the clock speed dropped back to 800Mhz it generates errors at a frequency of about 1 per minute. Client side hashrate shows ~350kh/s but poolside shows around 327kh/s.

Hmmm yeh i know what you mean , its hard to tell if its the mods fault or its just your stuffed up mofset Grid, hmmm I am still waiting on all my accesories to start modding. someone with awesome soldering skills would most likely have fun trying this , hopefully someone does as this will give me an idea - I beleive having a mod that allows you to choose if you want higher voltage or not would be the most ideal mod of them all. This means you do not ever have to revert back to normal all you need to do is flick the switch and boom your back to stock mode

Actually...if you REALLY wanted to just "flick a switch", you could wire up a 3-way switch with the resistance values you wanted, and mount the switch to the side of the gridseed (I stuck my 50k pots to the side of the fan and used the shortest wires I could) and label it. That way POS1 = stock, POS2=mod.

The way mine is, I just unplug the gridseed and adjust the 50k pots.

Sorry I am not understanding pots? is that just resistor? Also Are we talking about this is based on Vmod3 right? I was thinking of Software switch but again, u said another good idea "physical switch" , 2 Wires on the 2 contacts in replace of the R52 resistor and those 2 wires lead you to maybe 4 different resistor with a 4 way switch hhaha.. Stock Mode - 47K Mode - 49.9K mode and then 52K mode

BOOOM we now have SuperVmod- Giving us the choice to Dual mine, BTC mine, Scrypt Mine, + Scrypt mine OC in 3 OC steps. Wink

Since I am not a electronic guy even though I have soldered a few chips and leds on mobile phones back in the Nokia phone days.. I would need detailed instructions to even attempt this. Also seems like it would be an AWESOME mod but seems like alot of shit that needs to be done... Which is why I initially thought, By doing the Jumper/short mod + changing over 1 resistor to the perfect Kohm amount.. then enables us to flick the swtich with software. Both are awesome ideas if they work , The Physical switch is a definite one that will work but = Harder to do... The Software/hardware mod is easier but Not 100% it will work.

I was looking at these miners and I thought of something to save room,

I was thinking of pulling apart 2 x Gridseeds and removing the fan on one, somehow attaching the heatsink without the fan to the bottom of the other gridseed with the fan , 1 fan is pretty powerfull, this saves us doing the 5v fan mod as now you are only using the 1 fan for 2, so bascially cuts the fan power in half. And ALSO saves room as you have basically mashed 2x grids together and giving the cooling from the 1 fan. WIth the mod this will make 1 double whopper grid with 10 Chips= 1000Kh +

Something like this >>> https://www.dropbox.com/s/gaykii3dlqvqfjc/mashhh.jpg

Edit:
even better!!>>> I just thought of making it smaller by removing the sink directly under fan in the photo and having the back against one of the boards This makes it smaller by only having 3 peices of sinks and the fan, like this >>> https://www.dropbox.com/s/8q278fnjgzd18hj/mash2.png - and maybe cooler as the fan is now closer to both boards. Not bad looking for a future 1000Kh little beast Tongue
