Title: I get only ~560Kh/s for 280x Radeon video card. (10000 DOGE Bounty) Post by: romanticon on February 14, 2014, 06:47:24 PM I get only ~560Kh/s for 280x Radeon video card.
I know that it is to low here is my config any useful help will be tipped. Ubuntu 12 Catalyst Beta driver. Code: "intensity" : "13", Thanks in advance Roman Title: Re: I get only ~560Kh/s for 280x Radeon video card.

(10000 DOGE Bounty) Post by: ShakinHandz on February 14, 2014, 07:32:23 PM Which beta driver are you using? I will post my config later.. I'm currently sitting at ~760-780 on each of 280x's. The 14.1 drivers brought me speeds down. I reverted back to 13.12 and all was well.

It's interesting what you are saying I'll try to install fresh with the 13.12, I guess it will be faster than trying to uninstall the driver. Please publish your config, I'll try it if I will get your numbers you defenetly will winn the prize. Title: Re: I get only ~560Kh/s for 280x Radeon video card.

(10000 DOGE Bounty) Post by: neflihim on February 14, 2014, 08:02:29 PM I have the dual-x as well and can only get 715K out of each. Try to pull engine clock down to 1035 in config I posted above.
I have 5 of them and use that config. I didn't notice that they were the dual-x before I posted the 1050 engine clock in the above config or I would have changed it.

Title: Re: I get only ~560Kh/s for 280x Radeon video card. (10000 DOGE Bounty) Post by: romanticon on February 14, 2014, 09:37:20 PM Ok.... here is on fresh install with 13.5 version driver
very poor results :( Code: "intensity" : "20", https://i.imgur.com/SvfBV3F.jpg Title: Re: I get only ~560Kh/s for 280x Radeon video card. (10000 DOGE Bounty) Post by: Wipeout2097 on February 15, 2014, 12:18:15 AM See this: https://bitcointalk.org/index.php?topic=435438.msg4849281#msg4849281

(10000 DOGE Bounty) Post by: backtrackit on February 15, 2014, 12:24:04 AM start by lowering lowering thread-concurrency until you hit the sweet spot, might want to lower intensity first to 13, then when you find best thread concurrency up the intensity.
Title: Re: I get only ~560Kh/s for 280x Radeon video card. (10000 DOGE Bounty) Post by: romanticon on February 15, 2014, 06:35:51 AM That is the best I get so far,
the settings that actually matters here is: "gpu-engine" : "1000", "gpu-memclock" : "1500", "intensity" : "13", "thread-concurrency" : "8192", if you will help me push it higher you will get the reward: https://i.imgur.com/KGr7Z5h.jpg Title: Re: I get only ~560Kh/s for 280x Radeon video card.

If you're mining on a 280x, and using a TC of 8192 (which you should), you NEED to use "--gpu-threads 2". I've tuned dozens of 280x, with all sorts of settings, and this is always the case. I've edited your config. Removed some unnecessary settings, tweaked a few others, and see if that works: Code: "thread-concurrency" : "8192", Title: Re: I get only ~560Kh/s for 280x Radeon video card.

Thanks crazyates, I do use "--gpu-threads 2" otherwise it's 300Kh/s --gpu-engine 1050 I don't know why but only precise --gpu-engine 1000 give me maximum performance. Any other value give 100k less immediately. Title: Re: I get only ~560Kh/s for 280x Radeon video card.

After looking into it more it looks like you would have to flash your gpu with a modified bios. I use winblows and normally use afterburner to overclock. That been said have flashed the odd card and is fairly straight forward to do. |
