If we get some coins that are 64 bit based, with some doublelongs in the code, I'd say Nvidia has good potential.

uint64_t like Keccak? (unsigned long long int) ... forget it. AMD does 400 MHash/s. nVidia peaks at 180 MHash/s

it's sad...

but hey, whoever comes first...

I was thinking Sha512crypt or something like that actually.

Hope someone can help me, I'm mining Maxcoin on Dell 2720 standalone on Win 8.1 with cudaminer-2014-02-09\x64 but am having overheating problems, with GPU going up to 90C.

I'm a newb to mining and have tried various settings getting 28000 khs with a very rapid heat rise to 22000 khs taking about 1/2 an hour to reach 90C using this config

cudaminer --algo=keccak -d 0 -l K56x32 -L 128 -i 1 -C 1 -H 1 -s 10 -o stratum+tcp://max.suprnova.cc:3333 -u xxxxxxx -p xxxx

Can anyone suggest better config to keep the heat below 80C even if I lose some hashes?

reduce the x32 to x16 or further. use -b arguments at or below 256 (powers of 2 please) together with -i 1, lowering GPU utilization (verify with gpu-z)

Christian

I tried as you suggested Christian, hash rate is 26500 avg but heat rises to 85+C in seconds with -b at 256 and 128

cudaminer --algo=keccak -d 0 -l K56x16 -L 128 -i 1 -b 128 -C 1 -H 1 -s 10 -o stratum+tcp://eu.maxcoinpool.com:4000 -u xxxxxxx -p xxxxx

Any more ideas would be most gratefully welcome.

Don't worry guys...memory hard algos are where it's at, and it's where nvidia really shines.

I'm looking forward to the Maxwell low power cards, if they come up with a compute 4.0 or even a 3.5 part with 4gb buffer and low number of shaders that outperforms the R7 240 4GB I've found my ideal card for yac.

Btw, if you do this mostly for fun, I think this crypto would be great target for mining once released:

yeah but someone else has already done the programming. where's the fun Wink

Anyone here in my thread mining not just for fun, but seriously for profit as well? Having a farm of AMD cards in your garage or basement?

nVidia is looking to get in touch with miners to interview them about their expectations for mining related products. Just be aware that you would be helping nVidia with your information and not your favorite GPU manufacturer AMD Wink

PM me with a brief summary of what you're mining and how and I can get you in touch.

Is this the reason you are keen on nvidia mining, if I may ask? Do you have expectations that they might surpass AMD on at least some aspects?

As someone stated above, I think the HC miners don't really care about the label they use, they just want performance, flexibility and stability. At least that's what I think.

Now you got my attention! NewEgg is asking $3K for one of those model K20. Assuming that we have one of those in our rig what kind of hashrate are we talking about? Is Cudaminer compatible with Tesla drivers or will it require mods?

I know a miner working with 8 Fermi based cards. These aren't much faster than the consumer cards. In fact they use lower clock rates.
But in sum this 8 card rig produces respectable hash rates (at a tremendous power draw).

The K20 would be about equivalent to a Geforce 780. And even this card is overpriced for a mining rig. If you don't already have such equipment in the lab, don't buy it for mining - way too friggin' expensive.

cudaminer works out of the box with such cards.

A good start would be a complete CUDA engine with "4.0+" capabilities. What's does that 4.0+ mean? A device that has uncrippled integer performance (my 760 is crippled because only on 3.5 there are shifters??? Roll Eyes

) that without hardware assist already offers 500Kh/s scrypt for 200€ (compared with the 470Kh/s at 170€ for R9-270). That '+' means dedicated transistors for one or more SHA2 units (if I have a damn clue what I'm talking about Tongue

) and whatever other acceleration possible without being too costly.

Then, resale value and power usage. For resale value, perhaps video out is necessary. At worst I can still sell it as a used videocard, unlike those Tesla server units. Power usage means unlocked undervolting, power/performance profiles, etc...

What you want is some sort of asic build by nvidia... a graphic card without video out lol

these things already exist, as Tesla Compute cards. Wink

and the mining market seems to be asking for exactly this, minus the huge price tag.

I'd totally fill a PC with Tesla K40's if they weren't $5k each: http://www.amazon.com/NVIDIA-900-22081-2250-000-Active-Computing-Processor/dp/B00GR8FHB6/ref=sr_1_1?ie=UTF8&qid=1392236445&sr=8-1&keywords=tesla+k40

https://bitcointalksearch.org/topic/pre-ann-curecoin-development-continues-330685
They seem to be serious about it, not rushing with the launch, seemingly strong team behind it - And, I smell something "fishy" with the nvidia giveaways etc... Maybe nvidia might be preparing something for protein folding? Or maybe I just have high hopes

If you don't care about the profits that much, then directing your miners to this would be useful.
E: Although I think this one might actually survive quite well among all the other cryptos and actually be profitable for quite some time.

So what is everyone mining right now?

I am mining some MicroCoin at the moment because I find the coin has potential.

A newly setup rig for a friend is test-mining Yacoin on some low end cards until the six GTX 660Ti cards arrive.

Christian

I'm on microcoin too, doing almost 200 KHps with a GTX660. That's around 180 kMRC /day (4 to 5 mBTC at the going rates on poloniex). Still better profit than MAX.

I wonder though if I got the settings right (--algo=scrypt-jane:MRC -d gtx660 -i 0 -H 2 -m 1 -s 1 -C 0)

Are the MRC estimates from the pool? because in the pool I mine the estimate is about 80k/day for 340 kh/s.

Can I say for fun? I've always loved to build PCs from components.

I already knew CUDA and wanted to use my available hardware to the extent it was possible. OpenCL mining software would not do this - nVidia devices were a laughing stock. I used the early, promising cudaminer work as an excuse to upgrade my outdated hardware (dual GTX 260, and a GT 460). After the surprising LTC boom I invested in a ridiculously overpriced high-end nVidia mining rig purely as a proof of concept. Did not expect return of investment anytime soon. I improved cudaminer to drive the new rig with a weak CPU. I implemented other algorithms such as scrypt-jane to look for interesting profitability niches. I built a second rig and made a surprise hit with Keccak-hashing in Maxcoin (which paid for all the nVidia hardware several times over).

I am currently looking into expanding my second rig and await the upcoming Maxwell launch with great anticipation. Going to investigate the use of PCI express risers with nVidia cards also.

Haha 660tis ftw! I'm running 2 atm and probably going to buy one more for mining/3 way sli for gaming.i just hope they continue to drop in price -200$. What kh/s you get on your 660tis? I'm getting ~315 kh/s oc'd. And thank you very much for your work on cudaminer mining nvidia would suck/be pointless without you.

A good software engineer like Chris costs at least $85/hour in the US. I don't think that the bounty being offered here is fair!

To be fair the bounty for this type of work should be 10 BTC or equivalent in LTC.

However I see your point there - it's not much of a offering on individual level.

but here's the thing: If you people shelled out boatloads of BTC you might be quite disappointed if the effective speed-up is only 5x over the currently available CPU miner. And in the meantime someone might optimize the CPU miner for AVX2 or SSE, catching up to whatever speed-up was achieved on the GPU Wink

the best is probably to post a bounty in the altcoin forum (not here in this thread) for a CUDA implementation with certain mininmal speed requirements. I think there might even be one posted for 6 BTC already.

Christian

Also the approach of of faster mining ( be it GPU or improved CPU etc) would have an impact on the price of the cryptos, as (seemed) to happen with maxcoin.

I think the biggest issue with nVidia mining is the difficulty of programming:
There has been 3 different pieces of code for Scrypt mining by now, of which the 3rd was made by a nVidia ENGINEER.
As far as I know, Ati/AMD uses OpenCL, a language known much more than CUDA.

EDIT:
I have been mining YAC lately, would it be an smart idea to go MRC? Pooled or solo?
I have one GTX 780 available.
