Title: Any optimized scrypt kernels? Post by: Trini8ed on January 15, 2014, 10:27:00 PM I need an optimized scrypt kernel for my r9 290's anyone have experience with seeing a kernel optimized for these cards?

Not really its buggy and no improvement over my 875 khash I get on these cards. Title: Re: Any optimized scrypt kernels? Post by: crazyates on January 16, 2014, 02:57:59 AM Haven't tried them, but I got a copy of the optimized scrypt.cl file, which lets you build new .bin files with whatever settings you want.
On our 280x, they got us ~10Kh/s improvements per GPU. Haven't tried them on our 290s yet. Download: (Note, not my dropbox, or files. This is just where I got it from). https://drive.google.com/file/d/0B_EJYw4JvsnvbndpY3F0ci1BOUk/edit?usp=sharing Rename the scrypt.cl files inside CGMiner to scrypt.cl.bak. Delete all *.bin files, and relaunch cgminer with your favorite settings. Let me know how it works for you? |
