Title: Small bounty for help to find best cgminer settings. Post by: CryptoMiner on February 06, 2014, 04:02:43 PM BTC I'm offering a bounty of $20 in coinage for whoever can simply help me with proper cgminer settings real quick. Whoever's settings yield the highest hash rate will get the $20 in btc.
Don't mean to be such a noob but I have a feeling these settings are completely bungled since I am using same settings across the board for 2 290x's(Sapphire) and a 290(ASUS) in trifire, soon to be quad 290x's and the 290 will go towards another rig. Board is a Rampage 4 Extreme, 3930k, 16 DDR3. Let me know if you need more info. Just let me know what the hell to do. I hope I posted in the right section, lol. Thanks to everyone who can help me out. I feel like I'm burning unnecessary power and not getting the best hashes.

Post by: satsumi on February 08, 2014, 06:35:17 AM Mostly keep it as it is, but get rid of --lookup-gap 2 and set --gpu-engine on the 290 to 1000.
Are you sure you want --failover-only? Without that setting it will only mine the first pool as long as it's up and working correctly. Setting --failover-only means that it will only switch when the pool fails completely, but stick with it if it's up but failing to feed work.

Sometimes I noticed it has had to switch when pool goes down so I leave it up. If it never switched, I'd axe it. Title: Re: Small bounty for help to find best cgminer settings.

Title: Re: Small bounty for help to find best cgminer settings. Post by: crazyates on February 09, 2014, 09:27:06 PM Is there any good settings for 280 to get over 700kh/s. Use SGminer 4.1.0. Use the 13.12 or 13.11b drivers. Do NOT use the 14.1 drivers for 280x cards. SGMiner settings: kernel zuikkis TC 8193 lg 2 w 256 g 2 I 13 core 1040 mem 1500 fan 80% No auto fan or temp-target or anything like that. Bump your core up 5MHz at a time until your hashrate drops. (1045, 1050, 1055, etc). On our GB 280x, some can go up to 1070, others crap out down around 1030. Hashrates between 710 and 740kh/s. Same card, same BIOS, same everything. Each card is different.

If it never switched, I'd axe it. If you remove --failover-only it will also switch when the pool is up but failing to send work. Setting --failover-only is saying "I want to stick with this pool as long as it isn't completely dead, even if that means having my machine mine nothing for hours because the pool isn't sending work."Title: Re: Small bounty for help to find best cgminer settings. Post by: crazyates on February 09, 2014, 09:38:11 PM Every card is different. A MSI 290 will hash different than a Sapphire 290. You need to find your settings that work well for your cards/system.
On top of that, each GPU will have it's own limits. Some cards OC better than others. Some will hash better than others. It's all a huge mess. There are some known starting points for you to work off of. Example is the TC. A lot of people use TC 32765. Try what other people are using, and see what other people's setting get you. If you're not happy with that, check out these two blog posts. They contain a set of scripts that you place inside your SGMiner folder, and run them with some set parameters. It cycles through, running a 5 min test with each setting, and then records the hashrate. Helps you see exactly where your cards peak, and where they fall off. You can use these to see exactly what setting will make a difference on your hashrate. http://www.holynerdvana.com/2013/12/cgminer-optimal-thread-concurrency-for.html http://www.holynerdvana.com/2013/12/finding-optimal-clock-speed-for-cgminer.html I would start with the TC one, and set a middle-of-the-road core/mem settings, say 1000/1250. Run the full TC test, and see what it says your best TC is. Then run the mem test, with a core of 1000 and your best TC. See how high your memory goes. I can only guess, but I'm gonna say your mem probably runs best at 1250 or 1500, due to timing issues. Then, run the core test, starting really low and working up, to see how high your core should be. You will have to edit the script files, esp when how it runs sgminer (it will try to run cgminer). Include your pool info, as well as known optimal settings, such as -I (or -xI), -g, -w, -k, and --gpu-fan settings. Title: Re: Small bounty for help to find best cgminer settings.
