i sell my GTX970, and i buy GTX980 . it is a great card .

buy pascal or you'll regret it.
when profit goes down, pascal can still mine and maxwell will shutdown.

With -pstate=0 on the opensource version it don't throttle my GTX 1080 runs at 2088/1387,8 24h ... on Windows 10 with the latest driver so I don't get the assumption the Opensource version would throttle..i can't let this statement pass ...since it is not the fact.

If you read his post, he has reduced the tdp limit of the card to 70% (105Watt). The sp-mod deliver 20% higher hashrate with the same watt as the opensource.

158MHASH / 105 watt is making 1,5047MHASH per watt. (gtx 970 standard clocks sp-mod #3)(70% TDP)
255MHASH / 150 watt is making 1,7MHASH per watt (gtx 1070 standard clocks)

It is a bit more than 105, 110-120 watts maybe. Those cards have 100% tdp at 163 watts.

Point is that opensource can do max 163MH but it needs 196 (tdp  120%) watts for that. Sp #3 only needs 120-130 watts (tdp 75%).

Sure you can run it at 196 watts with sp-mod too, it does 190-200MH then. I haven't tested absolute max with it, pcie cable with 2x970 gets too warm for my taste.

yeah lol, buying a 980 now it's not a thing anyone should do, pascal is much better in everything

how much with just 2000 core? i see you reached a crazy core, not so common with all kind of 1070

The point is that the sp-mod is stable on higher clocks than the opensource miner. Rednow just confirmed it with 322MHASH on the gtx 1070. (-i 27)
The highest he got with the opensource miner was 290MHASH.

(+11%)

stability with just one card not always means with 6-gpu rig.
that's why it would be nice to see the hashrate with default clock or even with little OC.

i concur, i need to see a 6 x 1070 rig in action with your mod sp, to decide if it is worth it to get the miner

So do I.

2 cards 300 mhash
6 cards 294mhash

But this can be solved. Red antantti last posts. The 1x 8pin cable is not able to deliver enough power, and with 6 cards oc drawing power from the mainboard you need to lower the tdp of all the cards.

[Vegetablepin]

1080 g1 2050 core -i 27 405 mh, I think this is stable. 400 mh is stable though with -i 26. 1080 doesnt scale well with overclock. windows 8.1.  -i 28 has nonce problems

1.8.1 vs sp#3 70% tdp, strix 970 vs strix 970, intensity 25, windows 7x64 368.81

This is a confirmed +20% increase

Did you measure the watt on the sp-mod#1 compared to the opensource?  (70% TDP is around 105Watt? )
Can you try -i 26 or -i 27 or higher if it doesn't crash or trottle.

158MHASH / 105 watt is making 1,5047MHASH per watt. (gtx 970 standard clocks)(70% TDP)
255MHASH / 150 watt is making 1,7MHASH per watt (gtx 1070 standard clocks)

NO it is not.

You are comparing apples to oranges with one card with a higher clock. The card on the right needs downclocked to match the one o the left.

Lets say we get the exact same car. You drive 75 MPH and I drive 90 MPH (your 20%), I'll bet you any amount of money in the world I will beat you in a race.

See how it works out when you don't do a TRUE test apples to apples.

He is running with a reduced TDP(70%). 115Watt instead of 150 watt. Do you understand the difference? The NVIDIA boost clock is unable to run at full boost with the opensource@only 115 watt because it is out of power, with the SP-mod the card is running @ full boost clock.

With sp-mod #3 and the Gtx 970 (28nm maxwell) hashing at 157MHASH @ only 115 watt he is close to the perfomance of the pascal chip(16nm) using the opensource kernel when you calculate Hash/watt

I understand the difference very well.

In any TRUE test if you can't run the environments in the EXACT same settings the the results are not valid.

The cards are in the EXACT same settings when you start the miner. But the opensource will trottle and downclock itself automaticly. This is a test of the quality of the kernel at a given powerlimit.

[antantti]

Guys, why is it so hard to understand?

1080 g1 2050 core -i 27 405 mh, I think this is stable. 400 mh is stable though with -i 26. 1080 doesnt scale well with overclock. windows 8.1.  -i 28 has nonce problems

Mining on a low difficulty can sometimes give Nonce already sendt error messages, but they should dissapear when the difficulty rise. But if you get Nonce does not validate on the cpu, then you should use an another setting.

OK then send me your kernel and I will down clock your kernel to the open source to compare the speed. That way it is speed for speed.

I have Maxwell and Pascal and none of my clocks have down clocked on their own. My cards have been the opposite. Boost has kicked in and my 1070's are running at 1840-1850 and never went to 1600.

I just want to see a fair comparison over a period of time.

[sp_]

At exact same setting my version is around

5-7% faster on the gtx 1070 and 1080.( +10% with oc and tuning).
maxwell compute 5.2 l cards are 10-25% faster
compute 5.0  750ti cards are 5-7% faster

OK then send me your kernel and I will down clock your kernel to the open source to compare the speed. That way it is speed for speed.

I'd love to see a screenshot of the 1080 above 400. did you remember to reduce the memclock? Use NVIDIA inspector -1000 mhz. Then you have more power to overclock the core..

ROUND 2

1.8.1 vs sp#3 70% 120% tdp, strix 970 vs strix 970, intensity 25, windows 7x64 368.81

Cards are sitting next to each other in that very same rig hashing together. Left with opensource right with sp #3. Same card, same memory, same bios, same asic quality, same default voltage. 1x8-pin power connector.

Intensity is 25 because that is max what opensource can do, core is 1486 because that is max what opensource can keep steady. For this test tdp is set to 120% which means 196 watts which is max what these cards can do without bios mod.

Let's get ready to rumble!



-edit- well it looks like left wasn't steady at 1486 but you get the idea.

[bensam1231]

Hey look you regurgitated the part about intensity I posted a couple days ago... Good job bro and you have no idea what intensity actually does. Higher intensity does not mean you'll have better hashrate. Higher intensity can actually produce worse hashrate and use more power.

It's not a magic value too, where you increase intesnity by 5 and it's magically that much better. Your lack of understanding of... well... anything is astounding and you try to use it as 'proof' something is working wrong. Reminds me of the guy complaining that Wolf0 broke his rigs because he purchased a miner that utilized his GPUs better and produced more heat while drawing more wattage... then pretended like his cards would always use the same wattage.

If you don't know what you're talking about, don't act like you do.


You can't do math. What Yiimp lists as actual is what it paid for actual MH/BTC in the last day.

this guy is funny, keep posting retarded sentence, like regurgitating, no what i mean about intensity is that he changed how intensity work, by assigning it other value, but as usual you didn't understood shit, and i was hoping for a code rewrite instead....

and yes you can do the math about any coin, only because you don't know how to do it, it does not mean that it can not be done, please stay away with your ignorance is infecting me

Assigned it a different value like 29 instead of 25? As I mentioned before, that number often times has little association with 'improvements'. Just because intensity is higher doesn't mean it's a better miner or vice versa.

He DID rewrite code, you don't magically get better performance by increasing intensity. Try it with Epsylons miner.

Of course I can do math, as can other people... You apparently can't and are saying yiimps actual pool estimate are wrong. We've already discusses Suprnova and Coinmine. Coinmine has been improved, but it's often times still wrong.

lol, my ignorance is infecting you? Don't be a dumbass that tries to pretend he knows what he's talking about when you have absolutely no idea and we wont have these conversations.

Thanks antantti. With -i 27 and higher core clock you should reach 190+. Don't know about the strix, but the gigabyte G1 gaming cards can go all the way up to 1650mhz with this kernel. (but they come with 4pin + 3pin power) and 250W tdp

[bensam1231]

You guys that are complaining about the 70% TDP are being dumb. A couple pages ago it was asked to compare it at lower TDP so we could get a comparison for same wattage. Those two cards are operating at the same TDP. That TDP is dynamic, meaning the amount of clockspeed you'll get on one card is higher then the other because SP's MINER STRESSES CARDS LESS!

That means it's more efficient. Which is why he's saying you can OC the stuffing out of the cards. MINERS DO NOT ALL OPERATE AT THE SAME WATTAGE! Even for the same algo, Epsylon can code one, Wolf can code one, and SP can code one, and you'll get different watt readings on all of those... IT'S ENTIRELY POSSIBLE to have a more efficient miner, meaning you'll get a higher hashrate for LESS watts. Since Nvidia uses dynamic clock speeds, when you limit by same wattage, which Anttanti did, you end up at different clock speeds and hashrates, because SP can PUT OUT MORE HASH at the SAME wattage.

If you notice in the second test, ANT limited instead by CLOCK SPEED and as such, you receive MORE HASH at LESS WATTAGE. Look at the TDP. The clocks are the same, the wattage however is not (TDP).

Jesus. There are no schenanagins happening here. What SP is saying is what you're getting, it's been confirmed multiple times by multiple posts.

You don't need to see results on a six card rig. That's dumb and stupid logic. Nothing will change. Matter of a fact you might even end up with even better hashrate depending on how well you have your power delivery setup (more cards using less watts means better power delivery).


In other news Lbry is poping again. It's still more profitable to mine ETH+SIA then Lbry on Epsylons, Lbry is more profitable using SPs miner. Taking into account fluctuations in the market, it's probably still a good idea to stay on ETH+SIA, unless you think it'll continue to rise.
