Any chance we get numbers on a 970? Also, are these stock figures or with OC?

I'm looking for an affordable motherboard for GPU mining that would have at least the requirements to be compatible with the latest GPUs. I think it is based on the PCI-E 2 or PCI-E connections, am I right? Sorry, but not sure how to set up the GPUs on the motherboard. I have been looking into ASRock motherboards (since they are cheaper) but I'm not sure if they are recommended for this tasks. I would like to know your thoughts about this matter. Thanks. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) You better look for AMD motherboards. You have the military grade type one A you can get up to 6 GPU's in there. http://www.ebay.com/bhp/pci-express-3-0-motherboard?_trksid=p2047675.m3443I have one question though, if I had to choose the most reliable or durable motherboard, which would be the ideal one that meets this criteria? Gigabyte or Asus Motherboards? In regards to how they look, I love Gigabyte better. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Do not use the military grade mother boards. They are too expensive. The mining has very low requirement for the motherboard, so you can choose the lowest spec MB. Any brand will do. You just need more PCIE slots and powered PCIE extension lead. Exactly. ASRock's Pro BTC boards (H61 & H81) are above and beyond every alternative. You better spend the money on better GPUs or better PSU but these boards are perfect and inexpensive.

It's quiet because we have nothing to discuss. We are all waitin for our awful dev to leave so Steven can get someone in who knows what's he's doing. In the mean time we just sit and wait . . . What else can is investors do? We have done our bit and invested heavily in this project like the owners wanted.
If you take on the roll as an altcoin dev you don't do it for 20minutes a month as a hobby. People such as myself have invested $15k+ in this project.
Ultracoin needs to attract more buyers/community members. we had them but due to bad Dev work and management they have gone. a financial investor needs to be found! All top 10 coins have millions. We had the unique fast transaction speed. That was a very attractive selling point!
Devs are busy with accumulaton of those cheap coins. When they buy enough they will release some news and pump the price. Pretty simple. You really think the devs are that smart when they can't even push a decent difficulty retarget?

I agree with Pallas, a new thread and a decision about block reward should be made so users aren't just hanging.

As far as windows 10........ I will never..never....never..install it on any of my computers...NEVER!
I'm with you there. I'm win 7 all the way and if that gets utterly obsolete, I'll join team linux instead.

I'm also interested though I'm curious about the speed of other cards (750 Ti, 970) and what happens if the goal is not met.
While the speed increase is massive, and even if it's 50% more across the board I'm only in with 0.05 (if I get numbers on other cards) because unfortunately the profitability of this miner is entirely dependent on the profitability of one coin, Feathercoin which is only going down since July. Sure, there's Phoenixcoin, Orbitcoin, Ufocoin and Halcyon but they are completely negligible in every respect.

hi all ...
can anyone help with this issue i have with the current build ...
im stumped as to why the 6th card on the new 'big' build of 980ti g1 and 980ti extreme refuses to work with the latest drivers ...
remove just ONE card from the lot - and it will run and mine ... and mine like a bat out of hell at that ...
the setup is exactly the same as the 750ti oc lp card setup - but these cards refuse to work with more than 5 cards ...
has anyone had an issue like this before? ... would it be an issue with onboard ram? ...
the system has 16gb high performance ram - h81probtc - g1840gpu - kingston v300 120gb sdd - 2 x corsair ax1200 psu ( 3 cards per psu - with the first psu running the power to the motherboard and ssd ) - usb3 risers ( all powered ) along with the 2 x 4pin molex power connectors ( as redundancy ) via the motherboard - 4 x gigabyte 980ti g1 cards + 2 x gigabyte 980ti extreme cards ( higher clocked ) for a total of 6 cards ...
when 5 cards of ANY combination are running - all is ok ... when the 6th card is installed - the boot refuses to load nvidia drivers ... the version of drivers plays no part in this as the drivers have been tested with different versions and they ALL do the same thing ...
fedora 23 x64 cuda 7.5 ( f23x64c75 ) and ccminer-spmod78 ...
the elusive 6th card is the only thing holding this monster of a miner back ... and is holding back the installation into its custom aluminium frame ...
any ideas? ... anyone? ..

Weird. I'd try only using 1 stick of ram (or disable dual channel), using one card as main and disable onboard graphics, try different BIOS settings (pcie link speed) and of course disable render standby, try different risers, drivers, etc. Also, disable USB3, only use 1 sata device (in case you ran out of PCIE lanes).

On AMD you probobly undervolted your cards to get them to use less power. On Nvidia you change the TDP of the card. You can do it in software with the nvidia-smi tool, or modify the bios. (voids warranty)
yes I modded the bios myself, 0.8V, stable at 860Mhz, 1250 mem (sapphire 7950 dual X oc) are you saying that i can run under linux, before loading ccminer, a nvidia-smi sentence that will change in real time the TDP of every card??? WOW!!! I thought that the only way was modifying the BIOS!, do you have any link / tuto or hint how to?, I will get right on it!. I decide not to modify the BIOS because if I fuck something up, there is no backup, in AMD 7950 there is a dual bios switch, if you fuck up your card (which I did more than 100 times when researching this) just move the switch to position 2, power cycle, move switch to 1, reflash, power cycle and good to go!, but nvidia has no switch!. GPU's in my country are EXTREMELY COSTLY, and there is no such a thing like warranty here, if you fuck it up, it's gone, one card to the bin basket. ![Sad](https://bitcointalk.org/Smileys/default/sad.gif) You can recover basically any screwed up BIOS in DOS with nvflash, you just need to plug your monitor into another GPU (onboard). You can even shut down your computer midway flashing a card and still be able to reflash it next boot. bathrobehero what is your regular ambient temperature?, I am in a very hot area, that could explain why my cards where working at 75C and yours at 60 ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I had 12CM spacing between them, and a 3000 rpm fan between every card to prevent that one card heat up the other one, still, in quark specially, it was impossible to lower the temperature below 70C, in lyra2v2 yes, usually where at 60 probably, don't remember exactly. true WD Green dies fast! for offline storage they are ok, but not for much else, even if you modify the parking time (i usually do, to 30 or 60 seconds), I always use black or red drives which has better warranty and lasts longer too (one of the few companies that has true warranty in my country, WD, and is excellent!) still mining kills a lot of hard drives, until i switched to usb flash, I killed about 10 or 11 wd black, reds, and seagate drives beyond repair, keep in mind that it is the mix of 24/7 operation, a LOT of power outages (here power is extremely unstable, we have short brownouts at least 10 per day) and at least 1 power outage a week, 1 of 4 may last days. (reason why I spend a ridiculous amount of money in inverter generators, smart UPS, solar panels, power regulators, inverters, I even have a low voltage line across the apartment for the essentials (battery powered)) add to all that, high temperatures and high humidity and you get....HELL !! hehe ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) About the SSD, mining OS does not write a lot, just moving the logs and temps to ramdisk is enough, a crappy kingston V300 will last at least a couple of years easy. of course someone mention that the 840 Pro still works, of course, it is one of the best SSD consumer drives in the market! I have one in my workstation and is fantastic and very fast!, but at almost twice the cost of the kingston, it worth it for your workstation but not for a miner IMHO. I had an excellent experience booting of flash USB drive, almost all of my stability and disk problems went away since i boot off USB flash drive, so I will keep doing it ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) hehe. (I know i am a stubborn sob ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) ) Sorry, I meant to write 70°C, not 60 for the max temp for the 970 OC cards (I have 60°C temp limit on the 750 Ti's). The ambient temp now in the room where the rigs are is 21°C and the hottest 970 OC card is 62°C (80-85% fan). If I remove the temp target on the minis, they climb to 74-77°C. I have no idea about the humidity. Power here also isn't the best but it's nowhere near as bad as yours so I guess that's killing your harddrives. The two WD greens I have and used to mine burst for over a year (stopped about 6 months ago) have no isses so far and are at 800 load cycle (5 min parking time). I don't store anything important on them though. Yes, the 840 Pro is great but mostly because it's fast but it still uses TLC NANDs and the crappy V300's which I have in all mining rigs have MLC NANDs which should be way more durable. I always had terrible experience with USB drives though, maybe I just used really crappy ones. Just to be slightly on topic: ccMiner SPMOD Release CUDA 6.5 vs CUDA 7.5 Performance Comparison

another reason is temperature, GTX970 works at a very high temperature (75C with 25C ambient, even with the three coolers, insane!) , I don't like that, as an electronic tech, i know temp kill rigs badly!, it's only a matter of time!.
Don't get me wrong Gigabyte GTX 970 G1 where fantastic cards, I love them, power density is awesome, they are extremely stable, beautiful (i know, I'm a nerd, can't help it) but when it comes down to power efficient, it's like 40% more than 750Ti (including the rig overhead!).
There's nowhere near 40% difference in efficiency between a 750 Ti and a 970 because they are both Maxwell cards. The only way you'd get such a huge difference is if you use a memory bandwidth/latency hard algo (old lyra2) but for most algos a 970 is about 2.7-3.1x times faster than a 750 Ti which reflects their power consumption. I have GV-N970WF3OC 970 cards which are virtually the same as the G1 ones and they never ever go above 60°C with 8cm gap between them. The 1 fan 970 minis on the other hand would go 75+ if I'd let them but I use a 70°C temp target on them. I plan on measuring the hashrate, power consumption, temperature for all relevant algos, for all the different type of cards I have with different power targets for a long time, I think I'll get to it later this week and share the results. also, mining, kills hard drives like crazy, unless use SSD which are expensive here.
Not unless you use terrible HDDs to begin with like WD Green series which keep parking the head after 8 seconds of being idle and are only rated at 300.000 of these parkings. 60GB SSDs are not expensive anymore (and preserve their price better) and I'm still below 1TB total writes on them after 1 year of constant use running several wallets. You can also use the free version of ramdisk to keep some of the read/writes off of your ssd if you want to optimize things even more. http://www.radeonramdisk.com/software_downloads.phpTrue, but then I'd have to buy more than 4GB RAM per rig. And I'm not worried though, SSDs are not that fragile anymore. The OS SSD in my main rig (Samsung 840 Pro) is still only at 12% wear (0 reallocated sectors) with 15 TB writes and 666 days uptime with all kinds of caching and indexing enabled for maximum speed. It will get obsolete way before it dies on me due to wear.

100%-95%-1%=4% ![Roll Eyes](https://bitcointalk.org/Smileys/default/rolleyes.gif) Mining: 4% No shit. What's the difference between the premine and the ICO? You basically can sell 96% of all the coins anyway. Why the hell would you even bother adding a useless PoW period (if you can even call it that) when your shitcoin could be the picture in the dictionary as an example next to the words centralization, obvious scam and desperate scam?

Replacement? None of them. Not even close.
The block size debate might only fuck things up if people treat it as a critical issue when it's not, yet and won't be for a good while.

I'm not sure about the early release but the poor early distribution is what most people have issues with: ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FdSe9cRz.jpg&t=665&c=RTKv0YYdxV0x1g)
