CCminer(SP-MOD) Modded GPU kernels.

[Kompik]

I get 270 Mhs with this mod, which is super weird. 1070 ASUS, 2075/3499 @ 100%TDP. Much lower than the 1.8.4 cc miner, does not even respond to intensity, still similar hashrate.

Can you open up gpuz and check the clock and PCAP reason?

I'm adding some more speed now..

This miner is very strange for me. Each time i start it i have different speed that si then stable. 250 - 280 MH/s, but still slow on high OC.


It is the latest:

Old driver? I see memory controller load. it is running the old kernel.

I will fix it in the next release

I had dark souls running minimized in the background and I didnt see it, i have three monitors sorry guys:D . Now running 309 MH/S which is about 4% increase for me. Great miner, thanks!

SPMOD LBRY is giving me 300MH/s. You guys and your super tight. TDPs aren't going to get normal hashing numbers. It still surprises me some of you don't associate turning down the TDP with performance. Equihash is a niche case, you can't strangle the GPU for other algos normally.

a 1070 is currently making $1 a day net, cost is included, this is 1 year roi without resale, resale is still very high on these gpu, 80% guaranteed

it's better than leaving your bitcoin doing nothing, this unless bitcoin go much higher after your purchase, that would be a bad luck

actually roi is always far less than the inestement of the gpu, even in the worst case you are still looking at 50% resale value, this mean that roi is 6 months in reality

i've always sold back my gpu without problem on private forum, gamers love used big gpu, i don't care about roi, because i switch immediately to the new gen cards which are more efficency, i never stay forever with the same gpu

Resale only matters at the end of the life of the GPU. I still have some 970s because they're still profitable. Even though they have good 'resale', they aren't worth anywhere close to what they use to be worth and it pays for me to keep them over selling them off.

ROI matters to everyone. That's the time at which you start earning money back on your investment. That doesn't change even with resale value.

So in 2-3 years when Nvidia releases then 2070 that replaces the 1070, you'll sell them off as you say, but you've still reached ROI and you still sell them for much less then they're worth right now. If you never reach ROI (because you don't care as you say) then you've never made any money and basically mining is pointless.

Yeah, yeah... I'm sure you've sold them in a backroom somewhere for 400% their initial value, that STILL doesn't matter. That's not the way businesses work. You can't have a constant stock that doesn't earn you money. That doesn't even make sense. Resale is just for recouping part of your costs. It's not something you do constantly.

You should know by now that mainstream coins rarely ever pay the most.

We've had this discussion... Matter of a fact that's where my SIB rage came from, however, there is only so many coins that can support more then a handful of people or GPUs.

LBRY Sp-mod #5 version 3 has now been uploaded to the same place

I got too many of

but it didn't happen before with 1.8.4 opensource

Does I need to lower core clock ? or just ignore it ?

I have reproduced the problem now. If you mine with a high difficulty, you sometimes get errors. diff >= 512

on yiimp and zpool you can set a fixed diff in the password like this:

-p d=256

diff 1-256 is working fine.

When diff reaches 384 errors start: 'GPU result does not validate on CPU'

OK first 2minutes does not have this problem and after set diff to 256 don't get error anymore on suprnova.cc

Thank you for your great works !

i mainly resale to switch to a better gpu and better efficiency, it doesn't make sense to me to keep mining with the same gpu when or if roi is reached

you can believe what you want but i've always sold them easily for at least 50-80%, with second hand stuff it's even better

if in your example nvidia release the 2070 after 1-2 year(usually this is the time frame not 2-3 years), i would sell the 1070 for 50-80%, like i did with the 970 after i bought them in 2014 and easily managed to sold them for 50% at least after two years, plus roi would be already done

and if it isn't done, with 50% of the value back you still managed to return all the money back(unless you're telling me that a gpu can't reach 50% of its roi in 1-2 years which is false), and in fact i didn't lose anything in any investment i did in crypto, actually i made money

To get the most juice out of this kernel you need to increase the powerlimit. Running with low TDP will cause the coreclock to drop and the card will trottle and hash is lost..

Yes. Just because you can run Equihash with a reduced TDP and loose very little hash, this is not the case for many of the other algos..

You don't 'mainly' resale. The only time you resell, is when a new generation comes out every 2 years. Buying a GPU isn't like buying certain grade produce to sell to consumers to eat. GPUs aren't something you eat and buy on a daily basis.

50% is a pretty big hit... A really big hit. There is a pretty big difference between half price and close to full price at 80%. Considering during the biggest GPU mining booms and after it all crashed, I resold my 280s for half their price, that's absolute worst case scenario.

Between the last three Nvidia major generations, 7XX, 9XX, and 1XXX there was a year and a half.

So you still care about ROI. Resale can be calculated into ROI as well... But once again, you're arguing for a extra $50 every year and a half on a GPU that earns you $300 in a year. If that GPU makes more then that $50, it's not worth selling. You're confusing ROI and resale with a argument we had before where we talked about opportunity cost. Yes, there is value in resale, no that's not the only thing you factor in when buying a GPU and ROI definitely damn well matters or you're slowly bleeding money away.

Yeah, Equihash is a pretty niche case scenario. It's like Nvidia's version of Ethereum. Ethereum weirdly allowed super low end and old AMD hardware to mine really well. Equihash allows Nvidia hardware to mine really efficiently. Neither are representative of mining algorithms as a whole.
