Litecoin Mining Guide

Litecoin is a cryptocurrency that uses an alternative, memory hard hashing algorithm called scrypt that wasgoed devised by mathematics’ prodigy Colin Percival. The algorithm utilizes SHA256 and a stream function called salsa20 to force devices that mine it to either use a loterijlot of memory or use dramatically more ALU cycles to perform a hash. With the parameters used ter Litecoin’s implementation of scrypt (N = 1024, p = 1, r = 1), each thread uses approximately 64-128 KB depending on the settings for lookup_gap and thread_concurrency te the mining program when mining with a GPU. Because GPUs have such rapid memory (bandwidth ter the hundreds of GB/s) and harshly 128-512 KB of RAM vanaf stream processor, they are ideal for mining Litecoin. This requirement for rapid memory te order to mine quickly results ter Litecoin being FPGA and ASIC resistant , albeit ASICs may one day come out for Litecoin, they are not expected to garner the same spectacle increases spil for Bitcoin (two orders of magnitude more efficient).

Use current recommend AMD driver (12.8):

Instruction line to run:

57xx cards: 2368-4096 (3200 is common)

58xx cards: 4096-8192 (5600, 7168, and 8000 are common)

5970 card: 4096-8192 (5632 or 8000 are common)

Guideline line to run:

67xx cards: 2368-4096 (3200 is common)

68xx cards: 3008-6144 (4800 is common)

69xx cards: 4096-8192 (5600, 7168, and 8000 are common)

6990 card: 4096-8192 (5632 or 8000 are common)

Use reaper or cgminer versions Two.11.Trio and up (see update below). Set thread_concurrency to somewhere slightly below 64 * bus_width_of_card_in_bits. So, for a 7950, that would be 64 * 384 = 24576, ideal values are 21712 or 24000. Find your bus width here: http://plus.wikipedia.org/wiki/Southern_Islands_(GPU_family )

7770: 8000 (200 kh/s, aggression Nineteen)

7870: 15360 (400 kh/s, aggression Nineteen)

7970 (cgminer): 22392 (

700 kh/s can be obtained with a core/memory ratio of 0.57)

7950: 21712 or 24000 (

7970 (cgminer): 22392 (

700 kh/s can be obtained with a core/memory ratio of 0.57 ) or 8192 (-g Two -w 256 -I 13)

7970 (reaper): 20992, 21712, or 24000 (

650 kh/s can be obtained with reaper and core/memory ratio of 0.57 , e.g. 900 MHz core and 1580 MHz memory. Overheen 725 KH/s can be achieved with memory overvolting.)

cgminer versions Two.11.Three and up can be used to mine with high thread concurrencies now. Go after thesis instructions:

WINDOWS: Open console and type

Usually it is most effective to have the memory speed of the card equal to or greater than the core clock speed. For some cards this is more significant than others, but this is generally true. From experimental gegevens for a 7770 , a (core speed)/(memory speed) ratio of 0.7 or less is recommended.

CGMINER: Use a comma to separate thread-concurrency values, eg. –thread-concurrency 3200,8000. Values correspond to the card number ter zeroeth order.

REAPER: Run numerous instances of reaper. To do this, clone the folder and then add “device x” to reaper.conf, where x is the number for the card ter zeroeth order.

The omschrijving amount of system RAM spil for the sum of all the vRAM used by the GPUs is required when mining with reaper . For example, 3x 5970s mining with thread_concurrency values of 8000 each would require 3x 500MB = 1500MB system ram (plus extra RAM for the OS). The memory requirements for 7xxx cards are also higher because of larger thread_concurrency values, for example a thread_concurrency of 24000 means 1.5GB system RAM vanaf card is required.

Some people state that enlargened hash rates are experienced upon enhancing the number of threads vanaf GPU te 5xxx series cards (-g # ter cgminer or threads_per_gpu # te reaper). That has not bot my practice with 6xxx or 7xxx cards, but you can attempt it and see if it helps out your hash rate.
