My Gigabyte 780 Ti's had terrible coin whine at first but in a few weeks of mining it completely disappeared as they burned in. On another note, when I was autotuning with cudaminer the card was giving a high pitch screetching noise and as autotune went further the pitch of the sound increased. Sounded something like Space Invaders from the Atari. no coil whine so far with the 980's (but I don't use 5.1sound... only some bad 2.0... ) I had the same high pitch sound when autotuning with cudaminer on the 780ti. Now on msi board (at least mine) the sound system (or whatever it is called) is just below the card... so if the shielding isn't adequate, I would expect some interference. The funny thing is that my first msi board was faulty, the sound wasn't working at all (only static)... and actually the only thing it was possible to hear from it was some noise when the gpu was running. I am not sure it is really gpu fault here but rather bad shielding on the motherboard. edit: actually the 2nd card is on top of the sound processor (which looks like a flow to me... why anybody would put something like that so close the the most power hungry part of the computer) I have a 780Ti and a 760 (both are MSI Gaming edition), on an ASRock X79 Extreme9 motherboard, and I've never heard any coil whine or other weird sounds since I first built this machine (just the whir of the fans). So I'm inclined to think you're right about it being more likely the fault of a bad MB than the cards.

Maybe...my MOBO is very good too....it is an Asrock Extreme 9 AC Z87 chipset, 4 WAY SLI ready etc Cheers

Anyone still mining Ultra Coin?
If so do you have a current bat for a 750ti?
cudaminer -s 10 --algo=scrypt-jane:UTC -H 2 -i 0 -m 1 -l t25x4 -L 4 -b 16384 -o stratum+tcp://stratum.tumblingblock.com:5555 Try -H 2 -i 0 -m 1 -l t5x24 -L 4 -b 16384 It's a little faster....correct me if I'm wrong I do get a little bit of a higher hash rate, went from 9.3 kh/s to 10.49 kh/s on 3 750ti's, but I also get some lower hashes that I wasn't getting. Sometimes it drops to the low 7's to mid 8's. Whereas the other bat was constant 9's. I guess they both work out to avg about the mid 9's. Thanks both for the help.

If you are going to leave your BTC on an exchange please send it to this address instead 1GH3ub3UUHbU5qDJW5u3E9jZ96ZEmzaXtG, I will at least use the money better than someone who steals it from the exchange. Thanks

For anyone interested, i have updated the backend of cudamining.co.uk again and cut off roughly 60ms of page load time. So its down to around 100ms from 160ms. Wont mean much but when i get 1000 views per day, that's 60 seconds saved. If only my gpu could handle my page building request, then you guys could shave ms's off it for me

Looks to only be the reference-based 970s. Just spend a little more for the Gigabyte G1 and you should be fine. I think I heard a little intermittent ticking from that area at some point, but they're mining right now and I don't hear anything but the windforce cooler and my case fans. Nop, look like all 970's are affected with wine, even gigabyte are on list https://www.youtube.com/watch?v=9yGtg-8zV8YMine msi 970 gaming are not reference, and find on net then asus strix, and others are also with wine...

Perfectly said. Just see this: ZOTAC: https://www.youtube.com/watch?feature=player_embedded&v=IGRXAOxkn9M Gigabyte: https://www.youtube.com/watch?feature=player_embedded&v=9yGtg-8zV8Y Asus: https://www.youtube.com/watch?feature=player_embedded&v=8ko7edYNolo MSI: https://www.youtube.com/watch?feature=player_embedded&v=ffVqmYdfCCc EVGA: https://www.youtube.com/watch?feature=player_embedded&v=Prl6U75Di_UAll brands with coil whine, some batchs just have more than others, others are imperceptible, kinda lottery.

That doesn't sound like coil whine to me, especially since they have metal chokes. I would guess if the whine is actually coming from the card, it's from a dirty power signal to the card. Can't tell what PSU he has in there, but my PC Power and cooling 850 gold is powering 2x970s, 1x750ti, waterpumps, 7 fans, 4xHard drives, and all components overclocked while mining. Nothing but fan noise for me on both cards. **EDIT: Actually that sounds very similar to capacitor whining I have heard in the past on numerous pcs, it's just a bit louder in that video. Maybe there's a bad batch or it's stressing another component on the mobo or psu and causing the whine?

I'll probably wait until a 980Ti (or something similar) is released, then I'll buy a 900-series.

Has anyone else tried using the Miner Control app located here? https://bitcointalk.org/index.php?topic=769239.0I just got it configured and seems to do a good job of auto switching pools for nvidia miners. Thought you guys might be interested. The configuration was pretty straight forward. I modified my config to use only x11, x13, x15 and Nist5. You can grab the config here. Just do a find and replace in notepad with your BTC address. https://mega.co.nz/#!BVwBzZzB!FNcyUuUvWnXaMHg27noz-W7sO6B9harfywpZiOhVlvw

I love it, and have been helping out the dev with bug-hunting and suggestions. I still have the Scrypt algos included, but it rarely ever switches to them (because they are usually so unprofitable for GPU mining these days). I also customized mine with a manual "pool", which is actually just a fallback in case none of the pools are profitable (for my electricity costs), in which it mines X11 at a multipool called CoinKing. With this, I also removed the X11 algo from all other pools, since I like DarkCoin, and have configured my CoinKing account to auto-convert everything to DarkCoin. I'm also trying to work with both the CoinKing operator, and the MinerControl dev, to see if we can get CoinKing supported by MinerControl (needs a real-time API, which CoinKing does not yet have).

Tonight I have to shutdown my rig to change my PSU (I sell the other ^^) And I thought "When is the last time I reboot it ? Can't remember ..." I was not disappointed ... 3 month 19 days Those 750Ti never crash ! I can't remeber having my BAMT and overclocked 7950 running for more than 5-10 days without a sgminer crash or sick cards

rig_81 it's because I have a Asrock BTC H81 mobo. The other one is rig_45 because of the MSI G45 Z77 2 mobo is enough, I have sell the third today (that's why I switched the PSU), mining is harder and harder with the high diff and BTC drop

Can a 750ti miner here fill me in on whether current mining is profitable above electricity? Assume a .11 rate. I've seen mixed calculator results so it's hard to tell.

It's sporadic. I use a tool called Miner Control which pulls real-time API data to calculate profitability (also using your own hashrates and power usage/cost), and my GPUs are (currently) all Kepler so not as power-efficient as the 750Ti (or the new 900 series), yet the net profitability still goes into the positive values now & again even with my power-hungry monsters. I imagine with more efficient GPUs, it can still be decently profitable, though maybe not what everyone was used to from back in the "glory days" of GPU mining.
