Title: Scrypt Mining on a single HD 5870 - Where do I begin? Post by: n4ru on August 09, 2013, 08:15:06 AM I bought an HD 5870 recently to be able to mine vanity addresses, and I'm trying to mine a bit of scrypt coins with multipool. Where do I begin? What drivers and settings are ideal for the 5870? Been doing a bit of searching but couldn't find anything recent for this GPU. With default settings it's showing me something along the lines of 155Mh/s? But that's obviously not right, as I believe I'm mining on a scrypt pool, and I've also read that SHA256 should be running @ ~400MH/s with a 5870.
What do? Title: Re: Scrypt Mining on a single HD 5870 - Where do I begin? Post by: MaGNeT on August 09, 2013, 10:38:19 AM I have 3 old HD5870 cards giving 433Khah/s each :)
I use the following line for CGMINER: Code:

What version of cgminer and catalyst do u use? I'm using cgminer 2.11.4 and Catalyst 12.10 (which are recommended on https://litecoin.info/Mining_hardware_comparison) and i run around 400kh for two. My Cgminer line is : cgminer --scrypt -o serveur -u *** -p *** -I 18 -g 1 -w 256 --thread-concurrency 8000 The memlock of both are running at 1200 and core clock at 850. I triend many config, and never went over 350kh per card, but i can't get those back. I read that people have around 400-430 with the same card... So if anyone can help...

But i did note that when i put "--gpu-vddc 1.15" to change the voltage, it immediately crash. Title: Re: Scrypt Mining on a single HD 5870 - Where do I begin? Post by: aKIA on January 07, 2014, 02:22:55 PM If someone is looking for the solution, here is mine :
Install AMD SDK 2.7 Install Catalyst 12.8 Run Cgminer 3.1.0 For the .bat file, use what is recommended for 5870 Now both of them are running at 414kh/s |
