Hi, hopefully someone with more knowledge than me can help!

I'm having trouble getting cgminer-3-7-2-gridseed-windows-alt to specify frequency per device.

Win 7 64Bit with Zadig drivers WinUSB (v6.1.7600.16385).

It will run perfect for hours at 1188 if it is set for all devices but as soon as I add the text for device specific frequency, the bloody thing doesn't run at all.

Here's my current .bat file which works perfect but with only one frequency.

cgminer.exe --scrypt -o stratum+tcp://somerandompool.com:1234 -u xxxx.xxxxx -p xxxxx --hotplug 0 --gridseed-options=baud=115200,freq=1188,chips=5

pause

Any ideas would be GREATLY appreciated as I've been trying for 2 days now Huh

--gridseed-freq 6D8765292997=1200

Thanks Ferris419... That worked.
I had done that before as its in the readme but I was specifying all the gridseeds.

Like this: (which doesn't work)

cgminer.exe --scrypt -o stratum+tcp://stratum.doge.hashfaster.com:3339 -u nlouks.worker3 -p worker1234 --hotplug 0 --gridseed-options=baud=115200,freq=1188,chips=5 --gridseed-freq 6D88566F4853=1150,8D782F955748=1188

pause

But as I'm only setting up two gridseeds, cgminer was freaking out because I was telling it the frequency twice.

By just putting this: (which does work)

cgminer.exe --scrypt -o stratum+tcp://stratum.doge.hashfaster.com:3339 -u nlouks.worker3 -p worker1234 --hotplug 0 --gridseed-options=baud=115200,freq=1188,chips=5 --gridseed-freq 6D88566F4853=1150

pause

It's not conflicting I suppose.

Thank you for your help

Also, how do you get the serial number for each one?

Run first:

Code:

bfgminer -d?

to get serial numbers and paths of connected miners.

I'll sell them for a competitive price, especially if one person buys them all. I'm thinking maybe $125 each shipped? Someone let me know if I'm way off, but I think that's a good deal.

I only bought the blades because it's less devices to manage and less cables. I don't have them in hand so I can't comment on any headroom or potential yet. They are the same chips that go into the Gridseed 5 Chip miners. I just like the blade form factor better.

Is anyone interested in buying my modded Gridseed 5 Chip ASICs? I have 30 of them, all modded and running 1188MHz with 49.9k SMD, modded by me. Combined they run 15.15Mh/s. I bought 5 Gridseed Blades and they will be here on Friday.

Price...?

Why do you think that the Blades are better...Any advantage...except integration...

Any overclocking potential...ideas...?

I posted an idea here:https://bitcointalksearch.org/topic/m.6222366 to resolve the shoddy work on the heatsink/pcb design in regard to it not making contact with all 5 GC3355 chips due to two components that are taller.

It's easy (if you have a steady hand) and takes about 5 minutes...afterwards you have perfect contact to all 5 GC3355 chips.

... and for your reference ...:

My post just above nst6563 post...explaining the reason for a bad contact between the chips and heatsink...

https://bitcointalksearch.org/topic/m.6208700

Good job, nst6563...

What are your results after the mod...any improvements...?

ZiG

ZiG, I saw a post where you had said you were able to run up to 1000MHz stable with the thermal mod above. Is that without doing any of the voltage mods? TIA

Yes, buddy...

This is what I am doing first...test them as they come...stock...no mods...@850MHz ...to check how good are they...each one... Wink

Second...: Apply the thermal mod...Paste...new, thicker, better thermal pads...shims, if nesessary...TEST again...Most of them are going to 950 min...1000Mhz...NO volt mods yet...!

Out of 10 => 4 @ 1000...4 @975...1@950 ...1 slacker @925MHz ...NO HW errors...this is my belief that every HW error is lost...non submited...unpaid work...this is like your miner STOPPED for this period of time...5-10-15 min...so I opted for NO HW errors at all...

Voltage mod next...I am using my own...Test again...etc...

Capisco...?... Grin

It is just me...you could create your own test/mod...

Cheers...Beer here... Wink

you cannot set individual speed on BFg only CGminer and Cpuminer

Actually, with bfgminer_gridseed_pr3 and bfgminer-3-99-0-windows-clean You can. Grin

Syntax is either using serial number:

Code:

--set-device gridseed@XX72117B5XXX:clock=950

or path:

Code:

--set-device gridseed@\\.\COM25:clock=850

That would be great if I could figure this out!

Can you post an example command line for me? I have 10 gridseeds and need to try and figure this out.

Thanks!

Also, how do you get the serial number for each one?

:/

If you look at exactly 1 page ago, I posted the full command.

Here, just in case you missed it

Quote from: simon66 on April 15, 2014, 08:52:53 PM

You can actually. I haven't found how to set only 1 with many units connected to the same instace but you can run this command here:

Code:

bfgminer.exe --scrypt -o ltc.give-me-coins.com:3333 -u username -p password -d gridseed -S gridseed@\\.\COM3 --set-device gridseed:clock=1000

@\\.\COM3 is the COM port for your device.

Kinda running late, I'll expand more when I get back from work.

Well, what Hashra says doesn't matter so much. Do you get 510 poolside as well?

Just because a few people have successfully pushed their devices to 1000+ with these mods doesn't mean you will have similar success. Depending on how stable the components are on your gridseed, mods may even degrade performance.

As an example, the bridge mod is supposed to push the stable overclock from 850 to 950. I have two gridseeds running with just the bridge mod. One runs perfectly fine pushed to 1000 (1 or 2 HW errors per 24 hours). The other I can only push to 925 (any higher and I go from 0 HW errors to multiple HW errors per hour). The only difference is the 925 one came from a later batch.

EDIT: This is not to say that modding won't get you any benefits. In most cases, modding will allow you to get more hashing power. However if your expecting to order 10 gridseeds and mod them thinking you're going to get 1200 MHz out of each one then you may be in for some disappointment.

My .078 LTC dual mode might net .06 LTC after power costs. I have to factor that in and conveniently seem to forget it sometimes. If the single resistor / single mode mod even nets only .075 LTC per pod per day then you are still way ahead. Easy 25% better.

Thanks for the info re: not pushing it too far. I don't have the skill set to do any repairs.

I think the gridseed could possibly handle the first mod (bridge + voltage=1 in command line) to reach 1000Mhz and dual mine. I don't think I'd push it farther than that though. I tried the dual mining mode on mine with the resistor mod. The Ubiq m3022m mosfet on mine blew the instant dual mining kicked in. That part is a real bugger to find in the US, but luckily I was able to cross-reference a part from TI (CSD17552Q5A N-Ch 30v mosfet) that met most of the original specs and it's back up and running now at the 1225Mhz scrypt only.

As far as I know, I'm not getting .1ltc a day either, just a little less actually. I've been using Clevermining and just switched to Multipool to try them out since they have Cryptsy integration. In the past 15 days I've gotten 0.02552966 BTC from Clevermining. I only have the single gridseed plus an nvidia gtx 560se (98kh/s). My ati card bit the dust unfortunately.
