Topic: [GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning - page 72. (Read 308807 times)

I am trying to run GridSeed on my old netbook with WinXP and getsuch strange issue.
If I enter 3 GridSeed devices (with hub or without hub) - it's not work
(cgminer 3.8 for BTC + CPUminer for LTC).

No problems with 2 GridSeed, but when I add one more - cgminer don't want to start...

Are there any other ways to run DUAL mode ?
1. Using controler LA (tplink) (but it restart often)
2. on windows cgminer 3.8 for BTC + CPUminer for LTC
 (too many CPUminer windows, no backup pools, no restart on down device, can't run CGwhatcher for LTC..)

It's probably not the fault of cpuminer or CGminer for that matter. Cpuminer works great. You can keep track of how fast it's hashing via pool stats which are fairly accurate averages of what the pool is seeing which is what actually counts anyway. Your local hash rate means diddly in this case.

It sounds to me like either your GS5 has no 12V power going to it or perhaps is being underpowered.
Is the cooling fan running? If so, you have 12V power and if the LED's are on and flashing, you have 5V USB power.

The only other things that can cause your problem are incorrect port speed settings or poor serial communications or, the GS5 unit is basically bad and should be returned to the reseller for a prompt replacement or refund.

Let me know if this helps you.
My hashers have been and are working perfectly on cpuminer.

First, you're not going to get a stable 400k hash out of a gridseed. You'd need to be running at 950 to do that, and you'd be getting a number of HW errors if you did. I've been running pretty stable at 900 with a couple of HW errors but this gives about 380k. Most people run it at 850 which is around 360k.

This is what I use for cgminer:

cgminer.exe --scrypt -o yourpooladdress -u username -p password --gridseed-options=baud=115200,freq=900,chips=5 --hotplug 0

If you get too many errors, change 900 to 850.

With cgminer, you'll see a low WU. Ignore it (it's incorrect). If cgminer is showing a correct "A" count (depicted by A: in the output) but you're not seeing it on your pool, be sure you have the correct wallet address. A number of pools gladly accept "donations" from people with incorrect addresses.

If none of this applies to you, post sample output from cgminer so we can see what's going on.

They have to be plugged in to both the USB and power. If there is no power, it will appear it's working (lights will be on, etc) but it will not accept any shares

I'm having some big issues with my Gridseed 5 chip miner.

The issues are:
1.When I used the official miner (CPUMiner one I think),no matter how many times it shows 'Dispatching new work...' I never see any shares submitted to the pools I use (no matter which pool I use and with their corrent URLs,clevermining.com,multipool.us and coinshift.com) so I gave up ever hoping I'd get the full 400+Kh/s as promised from my miner so I changed to CGminer 3.72 which does get shares submitted but I get much less than half of the total hashpower/coins I'm supposed to have mined on all the pools I've used.
2.CGminer often says accepted yet I never see the shares in my pool even though my internet connections ok and plugged in ok via the USB port.

I've tried everything I know of to remedy this but to no avail and am pretty frustrated now since there's no improvement and the instructions are even harder to understand than why I'm having issues in the first place.

If someone can just help me get back on track,I'd really apreciate this as I didn't spend nearly £300 for a miner that only performs at 50% or less of it's capacity (paperwight).Thanks

Who me? Right now wafflepool.

What pool are you hashing?

I've ran mine at 900 for about 8 hours scrypt mining. I restarted a few hours ago to test 950 but it seemed like I was getting a couple of HW errors every few minutes then so I switched it back to 900. At 950 you can break 400 kh but I don't think that's enough to counteract the increased hardware errors.

At 900 it seems you get anywhere from 0 to 2 HW errors per hour. Also, with cgminer the WU is reported incorrectly. You'll see something ridiculously low (like less than 1/m), but the shares are being submitted correctly (verified on the pool website).

Absolutely no heat issues. PLan to keep my drinks cool with this thing in the summer. Running on an old 12v 3 amp power supply I had lying around.

 I restarted about a couple hours ago, so here's a snapshot since then:

my team runs 96 miners per server

Looks like people are reporting freezes with the Pi here:
https://litecointalk.org/index.php?topic=9908.225

I should mention that this second "fix" was already applied before I tried to use cgminer for the first time on Pi:

Not sure if I will waste too much more time on the Pi...would be nice though. I believe that other are having success so it's almost a challenge...but not quite

For reference here is my commands in full (after the initial menu config):

Stock Raspbian Wheezy (2014-01-07-wheezy-raspbian.zip).
Not too hip on using a pre-compiled executable but I may give that a shot before returning the Pi (https://db.tt/UygLkqwd). Kinda a deal breaker though since I don't want to wait for compiled versions to be released when new changes are made to the source.

anyone going to get the bounty?

I am when I think I'm being attacked. Again, sorry for my misinterpretation of your original query and intentions.

As the old interwebs adage goes, don't feed adversarial fellows

It wasn't obvious to me. Hence the question.

You're a rather adversarial fellow, aren't you?

No, obviously not.....

Currently, cgminer/bfgminer supports overclocking but 850 is as high as you can overclock without additional hardware errors and/or additional rejects from the pool. 850 is what everyone is using that has these chips so i'm offering a bounty for the first person to overclock beyond this point.

I know about the OC'd cpuminer. I'm referring to this:


jmordica asks "for the first person that can overclock gridseed 5-chip devices in cgminer or bfgminer without additional HW errors and rejects" and you respond "Cool! I'm doing it now with cpuminer ..."

So I'm wondering how overclocking in cpuminer answers jmordica's question - you're saying the cpuminer OC code can be adapted for cgminer?

Perhaps I misunderstood your query. There is a special OC version of cpuminer available. http://cryptomining-blog.com/?s=over+clock+gc3355
Sorry for the misunderstanding, if so....

Yah, right! Anyway.....

It is Germain to the subject.

Yes, the feeling of stupidity is frustrating, isn't it?

You should really keep that spelling and grammar "corrections" shit to yourself. This isn't a grammar forum.
