Memory is the same across all GPUs except for some weirdo models, so +400 is the same for everyone.

The problem is there's probably 50+% of nvidia users out there that mine in P2 mode and just don't know how to force the miner to P0. So +400 will only be something like "+200 from stock" for a lot of folks.

That's basically a OC. Also not sure why you'd go through the trouble of forcing p0 when you could just OC the memory right out of the gate. Less messing around. Maybe makes your OCD feel better? It doesn't seem to increase voltage to the memory and it doesn't allow you to OC the memory further.

Because there's a bug (or is that a feature?) in nvidia drivers or mining software that makes the memory clock jump ~ 200 MHz up when you close the miner's window. I didn't spend too much time investigating it, so maybe it's not all driver versions and/or not all miners that do that, but every single one I tried behaved that way. Let's say you've got gtx 1080 and your stock memory clock is supposed to be 5000. When you set OC to +400 (in MSI AB, for example), and run the miner, your actual memclock will be ~ 5200 or smth like that, and not 5400 (because cuda apps run in p2 instead of p0). Which would be ok, you could just add +600 instead to reach the clock you wanted (5400)... except when you close the miner, the memclock will jump to 5600 for a brief moment. And that is a problem - if you're pushing you memory overclock close to its max, then you'll get the driver crash in that short moment when the clock jumps to +200 more.

If you force cuda apps to run in p0 mode, then that jump is gone, the memory clock stays at whatever you set it to even when you close the miner window. And yeah, it does allow you to OC memory further, because without that weird jump you don't have to leave so much headroom for that brief clock increase and can set higher memclock.

Without a load on the GPU it shouldn't cause a crash. If you're getting crashes from +200 without a load you're already unstable. For instance you can do +800 on the desktop for pretty much any GPU and it wont crash. I would say +1000, but that's very close to absolute maximum and may crash just by sneezing at it.

+500 for instance is a pretty universally accepted memory OC across all my gpus when mining Ethereum (I haven't OC'd memory while mining Cryptonote or NeoS yet, so that might change). I was running them at p2. They don't crash even though they went +700 upon exiting the miner. However. If I ran +700, almost none of them could run the miner at that, not just when closing the miner.

Maybe you're running super bleeding edge, so I guess, but for all intents and purposes most people aren't going to run into that.

Of cause you don't know. One of the reasons you are doing 2.5$ with 1070

I've no idea what exactly happens when that +200 jump occurs, maybe there is some kind of load in that moment. Maybe some calculations are still being done when the miner is closing (if there was no load at that moment, why would it go to p0 after all and not to some low-power mode?). I've had very stable rigs hashing for 24+ hours but crashing when the miner is closed (and then, after forcing cuda apps to run in p0 on those systems, they're stable at those clocks for days/weeks). I've seen quite a few similar reports from other users, afaik it's a relatively common issue.

[ivakar]

you are saying that current  open source miner on   1080ti   does about 550?
I guess with claims  like that its not so hard to sell mods

I am not selling anything I just tried the 1070ti on different exe files and they all do around 500, but perhaps you can point me in the right direction here. Where can I find the miner that does 1700? I am using cuda 9.0 and the latest driver.

here you are! you can see two gtx1070ti are working on 1360kh/s



I can share the link free for you, SP. remember my kindness please!
check the latest Klaus ccminer, I'm sure you know where to find it
 

and on gtx 1080ti are doing about 1670 kh/s. can you make really better then that?

[tamerdagli]

Whos got lyra2z pm me please for exchane, teper u menya vse est,bitcore,xcn,cryptonight,keccak,phi and all i need is lyra2z and i will give all the miners i have for lyra2z.
Thanks

How do you force 10 series cards into p0 mode?

Now he has the base to improve a little bit with his compilation tricks, if they work

https://github.com/nicehash/NiceHashMiner/issues/1000

Here you wil find the application. Run it. In profile "_GLOBAL_DRIVER_PROFILE (Base Profile)", goto section "5 - Common", Change "CUDA - Force P2 state" from ON (0x00000001) to OFF (0x00000000).

I believe nvidia inspector has this option.

Hmm afaik that only works for 9 series gpus. But I'm keen to know if there is a way for 10 series.

lol this isn't open for debate, although cute that you think it is, you have to defend your third world brethren. The average person earn $10 per year in your country, if you earn $100 per year, you're earning 10x what they're earning, that would be considered 'rich' by comparison to people in their country. Same as if you earned $200,000 in the US compared to $20,000 per year you'd be considered pretty rich (although that depends on where you live in the US).

The whole 'rich' term is subjective. There is no baseline for 'rich'. You can live in Uganda and say you're rich because you're earning 100x the average citizens income, but that's still peanuts depending on where else you're living in the world.

And again,.... You have no idea what You are talking about. Prices for expensive and luxury things here are HIGHER than in the countries with higher GDP.

Hi. Appreciate if u can help me as i was trying to bring my 1070 neoscrypt to ~1100 (what i read). i started with ccminer tpruvot latest version on win X64. i got ~850 Kh/S. i now downloaded ccMiner release 8.15(KlausT-mod) and while running i get error "Cuda error in func 'neoscrypt_cpu_init_2stream' at line 1432: Out of memory". It may be i'm doing begginer's mistakes (i'm quite sure) but i'll really appreciate help.. (what should i do get my 1070 to ~1100 Kh/s neoscripts).

I think he never knows what he is talking about.
He understand that his own IQ is not good at all. He cant even imagine that it is more than possible to make 3.5Roi in 5 months. I think he will kill himself if I tell him that there is a guy who made 3BTC the same time with 2GPU only (of course it was not pure mining but anyway).
So the only thing to increase his sense of selfgreatness is the fact that he was born in the country with high GDP. The mental abilities of that person are so miserable that he can't even understand that it isn't his own attainment and there in nothing to be proud of.

P.S. Oh forgot to say - guy is from low GPD country.

No he is right. Forcing P0 is important for memory intensive algos, you will never get high OC stable unless you force it. I dont know what +500 is, but every 1070 card brand and type of memory runs easily on 4400 MHZ, the better ones, samsung especially can go over 4500 being stable all the time.

[icolsuineg]

The alexis miner is doing 450 KHASH on the 1070ti, so you need a dev to change the code to do the expected 1100-1400 Khash. I am reaching 1300+ on the gtx 1070 with my cuda 9.0 mod and only 550 on the 1070ti.
$750 dollars is nothing. Devs need money too.

1360 with klausT on 1070 Ti, not extreme clocks, locked at 912 mV as one of the cards struggled on 900, 1898 Mhz (if you lower the clock you can probably do more with mem, but I'm on autoswitch with Lyra2rev2 and it needs high core and doesn't need mem, so I chose the middle road). Alexis does just a bit less, not sure why is that yours doesn't do it.

And yes, 0.05 BTC was OK-ish before, now it's $750 and profitability changes in a day or two so you might never get to profit as much from the difference. Profitability in BTC dropped as a whole. The 5 minute dev-fee kills auto-switching profitability, but it's in the Bitcore mod I paid for, and I never agreed to have this in my miner.

I believe nvidia inspector has this option.

One of the versions. Google helps
