I'll give it a shot...the XFX cooler looks way better. Max clocks on that one? Also, do you know if they make a 4gb variant? Thanks  EDIT: Beave you're the man... 2.12kh/s, much better now :p Surprising! You are welcome. I'm getting 2.35kh/s on the XFX now but only 2.04 for the U--share rate. I have 1100 on the gpu clock and 1050 on the memory clock. As far as I know, Sapphire is the only one who makes the 4GB as far as I know. Ah, interesting...well, these are dirt cheap, not half bad. The xfx one seems like it can clock higher with the better cooler. I'll test the GT 640 4GB with cudaminer soon as well...and then the new GTX 750 and 750ti cards. Looking forward to that. Tip incoming! |

I'm at 7kh/s on my main pc...4 r7 240 2gb's. They suck compared to yours Thirtybird :p
Ya, and I don't know why... What you were showing to me looked like not enough memory was being allocated, but your TC and LG were the same. I've got the 4 GB sapphire, but everything I was giving you was based on using only 1.6 GB of memory (single thread), and matched what Beave was doing on his 2GB cards with the same results - 2.5KH/sec. I'm using windows 8 64bit...I'll try linux just for the heck of it. I found 13.11 beta was slightly better but still bad, 1.75kh/s kinda sucks. Maybe the cards are faulty? :/ I'm at a loss... What is the make of your 2GB cards? If it is Sapphire, then we know the problem. Exactly...Sapphire 2gb R7 240. Suggestions? Ugh Sapphire is terrible... you were going for the bargain deal. Try single thread with lookup gap of 3 and raw intensity of 1272. I am getting over 2 khash/s with XFX under those settings (2GB). Of course, it is an xfx card. I wouldn't be surprised if you don't get anywhere close to that with Sapphire  I'll give it a shot...the XFX cooler looks way better. Max clocks on that one? Also, do you know if they make a 4gb variant? Thanks EDIT: Beave you're the man... 2.12kh/s, much better now :p |

Christian, I found a guy who has a GTX 750ti...I sent him a cudaminer link and some yacoin instructions, hope he does run the program and send me a screenshot, and I also hope it doesn't crash and burn lol
Any ideas or I have to wait for a new revision?

Christian, I have a few questions...trying to understand everything better. I was reading this thread: http://yacointalk.com/index.php/topic,530.0.html, and wondering what to expect from the new Maxwell GTX 750 and 750ti cards. They have 640 cuda cores, which are 35% faster than previous gen cores and 2gb worth of vram, gddr5 memory. They can clock as high as 1350mhz core and 7600mhz mem, easily without touching voltages apparently, whilst using only 60w at full load (stock) How would you say thirtybird's logic applies to nvidia cards and cudaminer? Low lookup gap and low amount of shaders, higher intensities (how would that translate into cudaminer?). I'm looking forward to getting a few of these new cards, or seeing someone else test this. |

Ain't nobody got time for that!  Let's put some pressure on this then, shall we? I promise the following: In exchange for a working, malware-free GPU riecoin miner which is significantly faster than CPU mining and works with Nvidia (integrated to the cudaminer would be optimal) I promise to donate to the creator: -10% of what I mine in the first 24 hours - 5% what I mine in the second day - 2% what I mine on 3rd day - 1% for days 4-31 Scrypt hashrate comparison 350 kh/s Anyone else in? quote this with +1/ I'm in and I'll add you to the list. Post your scrypt hashrate for reference and I'll keep updating the total donation promise to this post. lets see how much we can get! +1 Got a GTX 780 at home...716kg/s mining scrypt, 325 mining vertcoin, 203mh/s max, 5.33kh/s yac and 420kh/s UTC. If anyone can do this, I'm sure it's cbuchner1. 716khash/s mining LTC!!! am only getting a range from 450kh/s to 590kh/s and a rare few seconds of 630kh/s. Ive been using autotune and the launch config are usually T12x24 or T24x24 or between these 2 numbers. Any guidance would be great.  I'd say don't mine scrypt! :p Consumption is too darn high, nvidia shines mining different algos, say scrypt-jane, variable n factor scrypt and whatnot. You'd make more money mining ultracoin anyway. |

What is the best way to overclock Kepler with GPUs?
I don't think there is a "best" way to do it. What i do is: 1. Get the best configuration possible using cuda miner 2. Set memory clock to the lowest possible point (Mine is -502). 3. Increase the GPU clock by 10. 4. Wait 15 mins to see if you have any errors 5. If no errors or driver crashes go to step 3 else go to step 6. 6. If there are driver crashes or errors reduce gpu clock by 10 7. Profit! Thanks for the tips! actually, setting the memory clock at -512 decreases the hashrate and it is better to keep to its nominal value. I noticed that some times ago while experimenting on scrypt. On scrypt you might loose something like 30~50 hash/s. Depends on what you're mining...keccak uses barely any memory, so it doesn't matter. Microcenter started selling GTX 750 and 750ti's, Msi twin forzr's in particular. I'm really tempted to get 4 of em. |

found this gem about PANDA profitability Network hashrate = D * 2^32 / BT
D (Diff) is 150.
BT (block time in s) is 150.
so Network hashrate ~= 4.3GH/s.
With 500KH/s, which is equivalent to 1 MH/s for traditional scrypt coins, you have 0.01164% of the total hashrate.
There's currently 576 blocks per day, providing 500k pandacoin on average. So each day you're gaining ~33500 pandacoin.
33500 pandacoin is ~ 0,02345 BTC
With 1 MH/s DOGE is currently providing you 0,012 BTC per day. So with a diff of 150, pandacoin is currently twice as profitable as DOGE.
Sounds good...we might have a shot with our green cards :p I should get one of my 240s on risers and install the 780 again. |

Was reading a review on guru3D, they seems to say that there is nothing revolutionary in the 750ti (or 750)
Super low tdp for such perf levels...IF they come out with a 4gb version I'd be all over it (if it comes with that arm chip and compute 3.5-4) |

 "Moving on to more detailed benchmarks. In AMD titles, like Tomb Raider or Battlefield 4 the difference is almost nonexistent. Other games follow the same path. We have a 5% (Tomb Raider) to 38% (COD) performance difference. The average is 20%, so it’s safe to assume that we are looking at 10-15% difference. Let’s not forget Radeon R7 260X has 896 Stream Processors and 56 Texture Units, so it’s quite obvious that Maxwell is more powerful on architectural level, providing better performance with almost twice less power consumption. There is one key part that wasn’t covered yet. Because of extremely low TDP the clocks speeds suffered. NVIDIA had to choose the lowest possible clocks to obtain 60W. For that reason Maxwell GM107 GPU has extreme overclocking potential. In fact you will even find cards with 28% factory-overclocking. Long story short, you will easily be able to obtain 1200 MHz clock, but only with the cards equipped with additional power connectors." Looking forward to these... |

Download the latest version by thirtybird, yacminer 3.4.0 or something, go back 2 or 3 pages for the link.

Man, AMD GPU prices are insane now. I was thinking of expanding my rig but don't really want to overpay on a R9 290. Thinking about replacing the 2 780s I have in my gaming rig with a pair of 780 Tis and move the 780s over to a dedicated mining box. Good idea? Or should I wait for Maxwell stuff... heard that's still a ways off though (late Q4 / next year?).
I'd wait at least for GTX 750/750ti mining results...otherwise grab asus 760 mars cards like Christian did. 650usd for 8kh/s is pretty damn good. Or go and get R7 240 4GB or 7850 4gb cards for yac mining. |

Take your time...that Nan guy's miner is pretty darn good for AMD it seems, but I wouldn't be surprised if his 'cpm' are not realistic. 280X cards are pulling 3375 with two instances per card and a slight oc. That's better than an r9 290 or a GTX Titan.
It's in my to-do list. Currently stratum is giving me lots of head aches because of being so poorly documented and cgminer's source code is so ugly that I can't read it lol, I hear ya...yet that kolivas dude raked millions in BTC donations, meh I'll release my stratum implementation too. Everything works except target derivation Great, keep up the good work. Looking forward to trying your program. |

Christian, please -- and this isn't completely related with coin mining -- if you have direct contact with Nvidia and Maxwell chip has indeed an ARM CPU, tell them to add an USB interface (or supply a separate USB hub that links to the first few PCI-e pins) and allow standalone operation. No motherboard, no Intel/AMD CPUs, no 4gb system RAM, no Windows. Just plug the PSU PCI-e power pins and the card boots ARM Linux from a connect usb pendrive
I'd like to add a bit to this request. Could we also see a parallel port added to the video card. If i'm going to run Linux, I'm going to need to print. Ethernet port would be logical as well, so I can connect to the internet. Maybe a few sata ports, so I can connect storage harddrives too. If this is going to run an OS, it should allow me the ability to have decent storage, at a decent speed. Sata is way faster than usb, even usb3. And lastly audio output. Both digital and analog. Get lost. In this thread and forum, we're not talking about "videocards" but mining devices. Except you're talking about a video card. Last I checked, we were mining with cudaminer on....video cards. Maxwell is the architecture of a GPU, on a video card. Nvidia don't make mining devices. They make video cards. My post was a joke, so calm down. You're asking Nvidia to turn their *gasp* video card into a standalone computer. I found it funny you were requesting a company add USB ports to a *gasp* video card. No, cudaminer runs on more than videocards, for example the Tesla supercomputing PCI-e cards. Read this thread a few pages back! Nvidia is interested in feedback from coin miners. This, it's a valid request...it would turn them into scrypt-jane asics :p I'd buy 999999999 of em. |

I think 85% is the highest recommended fanspeed for longer durations. I wonder if the 250 is faster than a 5/7770.
Nope, it is like a 7750 or worse. But it mines yacoin well... |

Nobody cares about Maxcoin in this threat anymore?
Diff has increased 2folds and the price 4folds as well.
Mine this while it is still possible, my cudaminer folks, my prediction is it will explode again soon.
I was able to mine 1k Maxcoin in few days when the price so low and the diff low as well. I mined and won't sell a single coin.
Yesterday when the price was increased 5folds I sold a few coins to cover my lost in the last few days. Keep the rest for the next explodes.
might give it a try again, the R9 290x has just arrived... and it has a backplate... (the real question being why the gtx780ti doesn't have one...) R9 290x are awful to mine. Too much expensive and consumes too much power. already paid for itself (actually the 780ti paid for it). well I guess, when you have many cards and miners, what you say count. However when you have mostly one pc, you want to maximise the hashrate/pcie 290s are just as good and cost less, that's what he means...but with recent price gouging, you could get the 290x for less at times xD I'd just get 290x directu for gaming, or a 780ti or 780 classified personally...for my main rig, but for mining I'd go with something more power efficient. |
