If you could manage to do a 'summary view' with data at the top like cgminer I think it would be absolutely perfect. May as well call it Seedminer at that point too.
Topic: GridSeed 5-chip USB miner voltage mod - page 29. (Read 156988 times)
I LOVE that new build of cpuminer Sandor. The gridseed I just got today and modded has individual cores sitting nicely at 1250Mhz, 1275MHz, and 1300MHz.

Can someone using 20+ gridseeds on Cgminer PLLEAASE help this is starting to get serious and I am loosing $$ each minute this doesnt get fixed..
Main issue -
LIBUSB send work write error certain random pod Disconnects and then CGminer crashes.
I did try the latest CPUminer, and I really do not understand how people can use this, WOW what a shame CGminer has problems.... talking about that I also give weird random USB Disconnects, difference is CPUminer doesn't crash after . One major problem for me is I cannot even tell how many miners I still have running on the session, It doesn't give me individual performance stats, it also gives pool type total hashrate...
Please I need someone that likes Cgminer like myself and hopefully knows some coding or even know some trick to stop what happening on my end
Edit: I am now trying another 10Port USB hub to see if this was the thing playing up - But please some advise would be great from people who use cgminer for big numbers

I run a script that restarts cgminer if it ever quits. Then just start the script with sh script.sh
#!/bin/bash
while true; do

done

I am currently running 22 voltmodded of a Windows 7 AMD E350 system. The PSU is a 750W Corsaid Gold efficiency. At the wall I get 435W usage. I measured the windows system and it pulls 30W. So that makes it 405W at the wall for:
- 22 GS units runing at 1175Mhz+
- 3 powered USB hubs
- 22 low power 80mm fans (I replaced the stock fans with quiet ones... they draw about 0.75W a piece).
- 3 low power 140mm fans (about 1.25W a piece)
- 2 low power 120mm fans (around 1W a piece)
If we discount the Fans, it averages to about 17.5W pe GS unit, all running at 1175Mhz+.

What are you using to calculate your Wattage? Math or a power meter between the wall plug and power supply?
Do you know what the powersupply is using in those numbers?
it's one of those cheapcake 60W brickstoo bad i neither know its efficiency nor have something which is 12V and has a known draw
and dont have an 5A capable ammeter, too
maybe i could hook up a halogen bulb or such if that helps...

Nice work Xer0.
Looks like almost double the power consumption for only around 43% performance increase (using 360KH/s as a baseline hashrate and 510KH/s for 1200Mhz )

If I buy gridseed 50 chip and add this mod?
How much is the breakeven time
How much is the breakeven time
I'm running 3 gridseeds off an unpowered usb hub. All three have the 5v usb fan mod as well. I wouldn't run more than 3 on an unpowered hub though if they have the 5v usb fan mod. I think 3 might be stretching it as it is...but right now i don't have access to a powered hub.
Okay, I get you. No biggie. I haven't studied the schematics in such great detail yet. But I do know there is no relay on the card. At least not on any of mine or my customers cards.
Still, the 5V USB power alone makes what ever is driving the LED's, run. I asked GridSeed if they indicate logic drive is active, they said yes, and they told me that I was correct about my guess about what the 12V rail and 5V rails power. Like you say, maybe we're just not communicating well today
I guess we're both right but saying it differently. I don't know why they'd go to the trouble of reducing processing power to 5V, I mean that is going to pull more current and dissipate more heat hash for hash. I guess the processor chips are all 5V then. Oh well. No biggie. It's still powered by 12V
The fan just runs straight off 12V. We agree on that. But it can easily be powered by 5V as well. Much quieter and still does the job for Scrypt mining perfectly.
I'm working with someone on modding the blades now. So far a potential overclock up to 7.2MHs has been discovered but some of the driver components need to be beefed up before we can confirm stable long term operation. Pretty cool!
So maybe the 12v - 5v conversion is acting as some sort of inhouse usb power rail?
Just occurred to me.
So it must be possible to run them wihtout a powered usb port - the tplink was able to handle 20 or 30 i think, without the memory upgrade.
personnally im not into any of the blade formats , reason being a i think you can get more overclockiing inviudual chips /grids. secondly if a chip fails the chip out and down, small usb stick version are easier to replace if one goes dead. but i think there is greater potentail in the gridseeds than the usb stick format here plus its cheaper for one gridseed than 5 usb sticks. yeah i know blades would work out cheaper but right now i cant invest a grand and half for a blade. a gridseed is easier and cheaper to pick up - plus less risk through customs
I have a pretty good feeling that the 12V rail 'analog' and the 5V rail 'digital' grounds are separated or maybe tied together via a .1 ohm or perhaps just jumped together but the reason they use separate buses is to keep the switching noise - emi of the processors as far away from the driver circuit as much as possible. Just a guess.
No biggie on the blades. To each his own....

WRONG!
12V powers the processors and the fan is basically inconsequential where power draw goes.
5V powers USB UART, controller and all logic circuits and if you want, my 5V fan mod as well.
You cannot hash with only 12V or 5V seperately. Both voltages MUST be present in order to hash! PERIOD!
Yes you need a supplemental 5V power supply if you are going to run more than 1 seed from a standard USB port. PERIOD!
You need and can safely use 13.8VDC 'standard output voltage' from any 'good' working power supply.
If you are only mining with 1 seed, you can do so without supplemental power pretty safely I would assume. I haven't done it since I started out with 4 pods, and now have 6 modded pods running and soon will have more modded pods hashing away making me money 24/7
Cool!Good luck!
the 5v from usb is just for that the uart com link. nothing more it doesnt draw any power from usb - unless there is the wolfy fan mod.
Here, let's try this.
Plug in the 5V USB power alone and see if the seed will hash and produce shares. The answer WILL be NO!
Next, try 12V power without 5V USB power. Same result. The answer WILL be NO!
Then plug in your 12V power and 5V USB power and see if they will hash now. The answer WILL be YES!
You're either mistaken or confused. The 12V is needed for processing to occur. It also powers the fan, yes but the fan can be connected to 5V USB power with very little current draw i.e. 78mA nominal.
The 5V feeds power to the logic circuits that run the chips, not the actual switching side of the chips that do the calculations etc. 12V IS what powers that!
Also, think of it this way. Why else would we need 12V 20 to 30 AMP power supplies to feed power to just the fans?
Get it?
Okay, hope this straightens things out for you!
Whew!
Like i said check the schmatics. 12v is converted to 5v, feeds the fan and passes to a relay (J2) although dont see no realy on board?.
Seriously i wonder wihtout the fan, could we power it on 5V? remove the 12v 5v conversion - otherwise the 5v would be converted lower and probably wouldnt power anything then.

Does anybody have an example Conf for BFGminer to run in CGwatcher that shows how to setup for multiple Gridseeds using the ID of the gridseed and the frequency for it?
Thanks!
Thanks!
im not sure about BFGminer but here is what im using with cgminer+cgwatcher.
bat file (run.bat)
C:\path\to\cgminer.exe --scrypt --gridseed-freq 6D7B068B5650=1225,6D79209A5148=1213,6D851F985148=1200 --gridseed-options=baud=115200,freq=1175,chips=5 --hotplug 10
add pool details to the config file (pool.config)
{
"pools" : [
{
"url" : "stratum+tcp://www.pool1.com:3333",
"user" : "worker.name",
"pass" : "x"
},
{
"url" : "stratum+tcp://stratum.pool2:3002",
"user" : "worker.name",
"pass" : "x"
}
],
"kernel-path" : "/usr/local/bin"
}
then on CGWatcher > settings > profile > manage profile > New
select "run.bat" as miner path
and
select "pools.config" as the config file and save, that's it.
you can use reset usb/devcon.exe script and add a scheduled task on windows to run it every 60 sec so you dont have to unplug replug miners to identify them.
How many HW errors...?
BTW, Did you measure the Voltage supplied to the Gridseed chips...What is it...?
