Maxcoin tips for highest performance

post #1 of 27
Thread Starter 
Hello every one

my first post about mining

for those who mine maxcoin (Algo: SHA-3 Keccak)
required Cgminer can be downloaded from http://max.1gh.com/

to squeeze some extra hashing power you need to

Lower the memory to the lowest possible number, you do not need memory for mining SHA-3
increase your core clock up by 15% - 18%
do not add any voltage keep it at default because with SHA-3 your card consume much less watt, and its temp are much lower than when mining scrypt

examples from cards i use

R9 290: core clock: 1125, Memory: 625, the rest at default, hashing power 465Mh/s
R9 280x: Core clock: 1150, Memory 750, the rest at default 390MH/s

its will be great if you share with us a screen shot showing how high you managed to get your cards.

Hope its useful for some of you, happy mining!

is that 2 x 290 or 1 x 290? cause when I mining max, I only get 240 MH/s max on it. what is ur setting for it?

i got 15x R9 290 devided into several rigs

all of them running at 460MH/s except 2 running at 455MH/s

my setting as following
using this CGminer http://maxdl.1gh.com/cgminer-windows.zip?nocache=0.7417075347620994

my bat file
cgminer.exe --keccak --no-submit-stale -o stratum+tcp://maxpool.1gh.com:17333 -u username -p password -I 14

on After burner

everything default except Core clock and memory

Core clock: 1100 - 1120
Memory: 625
Fan speed: 70%
Temps: 74 - 80c

hope this fix it for you, please share the results, you can also try changing vector from 1 to 2

EDIT: its a must to delete your keccak ~ .bin file after making changes to your bat file.
EDIT: dont go over -I 14, its will lower your hashing from 455mh to 0.5mh

so the core clock is higher than the memory clock. u sure it is correct?

So your saying decreasing memory increases hash? Or just reduces power usage without a hit on hash speed? I can not seem to reduce my 270's below 1400 memory.

first of all, we are talking about SHA-3 Keccak mining ONLY, not scrypt mining, and yes, reducing your memory will not affect your hash at all, its just to save your self some power, all what you need for sha-3 mining is to overclock the core clock as high as possible.

i get 803.1 mh/s

rx290x GPU 0 824Mhz 1250 mem (-20%, -20%) temp 85c fan 64%
rx290x GPU 1 927Mhz 1250 mem (-10%, -10%) temp 87c fan 50%

cgminer.exe -I 15 -w 256 --thread-concurrency 32765 --keccak --no-submit-stale -o

I wish max with quit dropping in price. need to pay off 2nd video board smile.gif

this is amazing, never seen someone pass the 600mh with his 290x, you gotta post a screenshot! just to not waste your time, above -I 14 its become 851kh not mh biggrin.gif

that is with two cards.....


my hash is nothing special because i have my cards under clocked 20% and 10% due to them hitting 90c temps...

oh ok, though you are talking each card, well, I see that you use --thread-concurrency 32765, you can remove this part, you will never need it with sha3 keccak, maybe its the reason for the high temp
try running it after that at 1100 core clock without adding any extra volts, you might actually be able to reduce the voltage at 1100core clock
put your fans at 70% 24/7, myself getting 87temp max, and by the way, its 290x, its ment to run at 95c without a problem
