Re: MultiMiner & MobileMiner: Your Coins. Your Pools. Your way. Win/Mac/nix/Mobl/Ava

I have problem when using multiminer: if Intensity=13 , the vga only load 96%, if increase Intensity>13, the vga will load 99%. but the best parameter for vga 797 is --worksize 256 --thread-concurrency 8192 --lookup-gap 2 -g 1 -I 13

how can I fix it ? I don't want to increase Intensity
please help me

If I only use cgminer (don't use multiminer), the vga load 99% with Intensity 13

As I said above, some 7970s perform poorly while scrypt mining.

Is one thread:

lots more if you search on google:

https://www.google.com/search?q=7970+low+hashrate+scrypt&oq=7970+low+hashrate+scrypt

this is difference case, you can read my post carefully and will understand
summary:

1. if don't use the multiminer, vga 797 will load 99% and get over 700K with Intensity=13
2. if using the multiminer, vga 797 only load 96% and get under 600K with Intensity=13

multiminer only work good with Inversity over 13

You use the EXACT same parameters as you do in your multiminer, right? mine hashes at 638 when i run on CGminer, multiminer reports 640, about correct.

what Invensity do you use ? only 13 ?

Here's one of my sample .bat that gets me 640 khps on 7950

Code:

c:
cd\
cd cgminer-3.4.3-windows
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://pool1.us.multipool.us:7777 --gpu-threads 1 --gpu-engine 1045 --gpu-memclock 1455 --thread-concurrency 16384 -u coldbreeze16.1 -p x -w 256 --lookup-gap 2 -I 20

This one leaves PC usable while generating 560 khps

Code:

Either work fine on multiminer. Never tried inserting an intensity below 13. You should check your shader/thread concurr value.

thanks for your helping, but I think you don't undersand what I write
1. I only focus vga 797 with Invensity 13
2. you only try to explain 795 with Invensity over 13
