Waiting for pascal:

VCASH sp-mod(0.2BTC):



Decred sp-mod(0.1BTC):

@sp - have you heard about the release of Pascal at all?  is there a promising date?

1. 0.1BTC: Pentablake +100-120% (3 releases)
4. 0.1BTC: All nicehash algos optimized. 0-10% (5 releases)(x11,x13,x15,nist5,quark,lyra2v2,neoscrypt)
5. 0.1BTC: decred +18-25% (7 releases) (Full sourcecode(linux) 0.4BTC)
6. 0.2BTC: Vcash(+13%+decred(+18-25%) (0.1 btc discount for the decred buyers) (4 releases)

I will put these 4 in one build.(1.7.6 refork) the price will be 0.4BTC It includes unpublished decred #8, Vcash #5, Quark #6. Discounts for the donators. So If you already have bought decred and VCASH you only need 0.2BTC more.

But you have already donated 0.3 BTC haven't you. (from the beginning of the SP-MOD project) Donators get discounts..

I also have a 3% x11 increase I want to put it the 0.4BTC miner.

@sp - have you heard about the release of Pascal at all?  is there a promising date?

There was some more news yesterday, but no release dates.

http://www.extremetech.com/extreme/226032-nvidias-pascal-gp100-gpu-massive-bandwidth-enormous-double-precision-performance

Tesla GP100 3584 cuda cores. 1328MHZ core clock.

The tesla cards are too expensive for mining. I expect the gp100 to be 25% faster than the 980ti. (based on cuda core count and clockrate.)

The gigabyte G1 980ti is mining decred stable @ 1600MHZ core clock.

if you care for profit and pay for electricity, don't overclock your cards :-)

if you care for profit and pay for electricity, don't overclock your cards :-)

You can clock your memory down to 500Mhz to save power, reduce the TDP to save power. Then the coreclock can go up to 1600 for "free". The decred sp-mod #8 only uses 29 registers, and is overclock friendly.

of course. it was an easier way to say "run nvidia-smi -pl SOMELOWTDP" ;-)

i'm having a problem when running more than one gpu, on a old algo like x15, the second gpu do not run at full speed, but it's not throttling, it simply sit there at low core speed, why this?
when i restart the machine for the first few seconds it begin to run at full speed, then the miner close and when i restart it once again it run at slow speed, tried also with the Yimp fork but nothing

it's ok around 20-30%, it only happen when i run the x15, and maybe other xX algo, after i run one of those algo, the first gpu stop working at full speed for all the other algo

please let me know what this will cost me sp - as im restarting the build of the systems next week ... and will be selling off ALL the gigabyte 750ti oc lp cards i have ...

i just havent found a place for thefarm yet ...

you have a record of what i have donated - so could you mail me an idea of what the residual cost will be for me please? ...

Oh dear, I've seen this too much. Here is what I know.

Sometimes when a miner stops and restarts, usually to switch algos, it will exhibit any of the following symptoms:
    - it will fail to start with the same parameters
    - it will start with reduced intensity (-i)
    - it will start in a degraded state, low clock

A reboot will correct the problem.
The occurrance appears to be random. Sometimes a card will get hit multiple times per day, sometimes not for several days
Only some cards are affected, some never exhibit the problem.
There is no pattern to the affected cards, Maxwell and Kepler have both been affected.
It occurs on Windows and linux.
It does not appear to be driver related.
It appears to affect only specific individual cards.

There was discussion about this several months ago. A search on "degraded" might find something.
The bottom line is it was never solved. It's possibly a HW issue.

I do have some new information, It may be heat related, possibly heat stressing a marginal component.
I recently moved an affected card to the basement where it's cooler. It had been crashing often when
profit switching. Since the move it has been more stable but I have not been profit switching with it. I only
switch manually every few days. I may setup profit switching on this PC to try to recreate the problem.

Well there ya go. It's one of those things that has been nagging me for a while. I feel better now.
You could try swapping the cards to see if the problem moves.

I didn't know that would work .. got to try it.

what i know is, it only appear with x15 algo and maybe other xX algo, all other algo are working right, so i think it's not so much hardware related, i've already swapped the card and the same problem is occuring
only one card is running at full speed(the one not in the first slot, in other words, the one that is not mining is always the one near the cpu on the x16-x16 riser, at this point it could be the riser, but i doubt because the other algo are running)
therefore this strengthens the fact that it might not be HW related, also one of the two card was recently rmaed because i thought it was the card causing this, but nothing, the problem is still there, now i'm running 361 drivers version, i'll try with 364 tomorrow to see if it change something

You probably have a different problem then. As I mentioned the problem I'm seeing is always the same card regardless
of the MB, slot, riser, OS or drivers.

Ccminer crashes on me on one rig profit switching. I haven't been able to figure it out yet.
But I'm going to put a timer in my conf file for MinerControl KBomba 1.6.5.1.
But the conf validates but doesn't work and I need help to get it working.
Anyone interested in helping me I will pay a little  BTC for as soon as I mine more.

What you're describing is basically a card crashing without the driver not recovering.
The GPU clocks are stuck at 405 Mhz, right?

If so then yes, the card crashed and switched to the lowest and safest power state (P8 state) and the driver recovery didn't reset the card.
Driver recovery usually only starts if the card doesn't respond for a while (TDR timeout) but this is not the case and the driver doesn't care which power state a card is in.

Basically the card poops itself because of one the following:
- too much OC;
- not enough GPU memory (usually from too high intensity);
- too high intensity;
- low quality or faulty riser or power cable or PSU;
- low quality card (increasing voltage a bit helps stabilize the card)
and then it goes into safe mode.

To solve this you have to restart the PC or more conveniently disable the card in device manager (if it's not your primary card with a monitor pluged in) and re-enable it to force the driver to reinitialize the card.
Or you can use a bat with:
nvidiainspector.exe -restartdisplaydriver
to reset all cards.

It's mostly caused by too much overclock and it can crash even after days of being stable. I have a couple of cards that I know can't handle the same OC as the others so I always have lower clocks on them. Otherwise they'd always crash eventually.
Also different algos have different levels of taxing the GPU so the same card will not necessarily be able to handle all algos with the same overclock.
Some algos are overclock friendly while others will crash the card even with a mild overclock.
So if you're using a profit switching solution you have to use an overclock that works for all cards.
This is why it'd be nice to be able to set clock speeds from within the .bat file for each algo but nvidia-smi only changes the memory clocks for some reason.
