1  Alternate cryptocurrencies / Announcements (Altcoins) / Re: Vertcoin - First Scrypt N | First Stealth Address - Privacy without mixer on: November 27, 2014, 04:50:49 AM
Hello all,

Pleace help me!

I have 2 x Asus R9 290x video card. Driver is 14.9.
My OS is Win 7 Ultimate, 64bit. My PC use 16 GB RAM.

I mining in wafflepool.com (Multipool) and using Scrypt-N algorithm
Use vertminer 0.5.4pre3 .. but i have a problem.

Code:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

vertminer.exe -o stratum+tcp://eu.wafflepool.com:3332 -u <BTC address> -p <password> --auto-fan -w 512 -v 1 -I 20 -g 1 --lookup-gap 2 --thread-concurrency 24550 --gpu-engine 940 --gpu-memclock 1450 --gpu-powertune 25

Written my unknown commands.

I decided to use old miner vertminer-0.5.2.
There everything is ok with this line:

Code:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

vertminer.exe --scrypt-vert -o stratum+tcp://eu.wafflepool.com:3332 -u <BTC address> -p <password> --auto-fan -w 512 -v 1 -I 20 -g 1 --lookup-gap 2 --thread-concurrency 24550 --gpu-engine 940 --gpu-memclock 1450 --gpu-powertune 25

Why the old version and everything works with no new? And what parameters should be changed? How are the norm indicators for both versions - kh/s?

Hello,

I have a problem.



This is sph-sgminer Fork with Whirlpool Algorithm Support. I downloaded from here: http://cryptomining-blog.com/3120-updated-sph-sgminer-fork-with-whirlpool-algorithm-support/

My card is Asus Radeon R9 290, Win7 64 bit.
My bat file is:
Code:
GPU_MAX_ALLOC_PERCENT=100
setx GPU_USE_SYNC_OBJECTS 1
sgminer.exe -k x11mod -o stratum+tcp://x11.ltcrabbit.com:3332 -u user -p password --auto-fan --gpu-engine 990 --gpu-memclock 1350 -I 18 -w 512 --lookup-gap 2 --thread-concurrency 24550

Please help me.

Thanks.

What is this error? This miner is it right? Please help me

Hello all,

One of my gridseed blade failes.

I fitted the following a 35v 220uf capacitor, 43k ohm resistor. I put three fans on all sides. Blade very shining.
Power cables began to melt Sad

Can anyone provide me with the schematics so i can repair it?

Thanks!
Hi,
there are no real schematics.
I'm using the 8 chip ones from gridseed github.
https://github.com/gridseed/gc3355-doc

43k resistor is only if you are crazy like me and if you are confident you can fix anything that will break or lose your money
39k is a safe one.

only one extra fan is needed to blow from one side of the powerboard.
plus dissipators under the PCB where the mosfets are, and on the mosfets, you can even add some to the inductance/coil/choke

Your cable started to melt because the wires inside are too thin.
You are asking for 150 watt / 12 amps on each PCB.
I'm using 0.75mm˛ wires with a screw terminal instead of the original 12v plug connector on the blade.


solder it under the PCB, not on the same side there was the 12v plug. It will be easier to screw/unscrew.
The solder point near the ferrites is the positive
The solder point nearest from the edge of the PCB is negative.

I did a detailed diagnosis of my device. All power resistors are healthy.
The chip that manages power is probably blown.
It is: UP1509P
Please tell me the site where can I buy this chip and it is guaranteed quality.

Thank you in advance.
Trifon

you can find it at farnell or reichelt

He's not there this controller.
Any other ideas?
