sp_ how much do you want for your quark private miner? or DJM? or even x11 and Lyra2REv2

Not for sale. But if djm34 sell his kernal I might sell it.

lol, you might have to wait a bit before selling then  

Just to summarize a bit the way I do things, for me for a sell to be profitable it has to reflect, somehow,
the time I spent in coding (regardless of the coin value ) hence if the coin value is low,
it wouldn't be profitable for a miner to buy from me or it wouldn't be profitable for me to sell below my time/money equivalent  
(and would be bad business practices as well since when I work for a coin dev I charge along that time/money equivalent).

so for the moment, it isn't for sale...

also as already said multiple times: trust is important for me... (private miners are sold in priority to people I can trust)

Disregard my last post. Looks like I had a partially corrupt hybrid CUDA 6.5/7.5. I reverted back to nouveau drivers, ununstalled CUDA completely, started again from scratch and voi-la! It compiles using 7.5. Didn't see any hash rate improvements, though.  

What cards do you have.
On the 750ti release 78: x11,quark, lyra2v2 and qubit should be faster. (than release 74 (cuda 6.5))

On gtx 970 only quark and lyra2v2 is faster

Is it normal?

Use @ CCMiner v1.5.74 for neoscrypt.

On the machine that I was messing with I have a single EVGA GTX 750ti, non SC. Not sure what release you'd call that. I mint almost exclusively using the quark algo. I have compiled versions 1.5.74, .76, & .77. With 1.5.74/CUDA 6.5 I think I remember topping out at ~5900KH/s. I tried checking it again this morning but since upgrading to CUDA 7.5 last night I now get "ccminer-1.5.74/ccminer: error while loading shared libraries: libcudart.so.6.5". I recompiled .74 against 7.5 and it now tops out at 5475KH/s but I'm not sure that's a valid test. .76 and .77 compiled with CUDA 7.5 both top out at 5900KH/s.

I don't know. What I remember of .74/6.5 might be wrong. Don't lose any sleep over it. I know you're selling souped up kernels for a premium and that's fine. I appreciate your work.

If you use cuda 7.5 use the latest version @github.
if you use cuda 6.5 compile release 74.

Use @ CCMiner v1.5.74 for neoscrypt.

More work is needed on neoscrypt. The compiler has changed. Alot of retuning / rewriting is needed.

In release 78 I added 50% from release 77.

If you compile DJM34's offical version with cuda 7.5 my version is more than 50% faster.:-)

[tbearhere]

No gains with p0 state on 960, 970 and 980. Only ETH gains some % with memory oc.
Anyway I managed to put all the cards to p0 state also in windows. It is the same "trick" as in linux using nvidia-smi tool.

I'm not responsible if You kill Your GPU. The risk is Yours.
The procedure is:
1) open cmd.exe with the admin privileges
2) cd C:\Program Files\NVIDIA Corporation\NVSMI
3) nvidia-smi -q -d SUPPORTED_CLOCKS -i 0
4) nvidia-smi -ac 3505,1455 -i 0

-i 0 means display adapter 0. -i 4 would mean display adapter 4.
Step 3 is used to show the possible clock settings combination for each power state. The numbers will change if You overclock Your gpu before running step 3.
The result after typing step 3 would be looking like that:

Code:

C:\Windows\system32>cd C:\Program Files\NVIDIA Corporation\NVSMI

C:\Program Files\NVIDIA Corporation\NVSMI>nvidia-smi -q -d SUPPORTED_CLOCKS -i 0

It always starts with the clocks of the p0 state. In my example it shows memory 3505 after that You can find listed all the possible graphics settings. You must chose one and type it exactly the same number in the step 4.

Example:
nvidia-smi -ac 3505,1446 -i 0
The nvidia inspector shows Your card in p0 and You can overclock also the memory with msi afterburner or any other oc tool.

If You type nvidia-smi -ac 3505,1440 -i 0 it won't be accepted because 1440 is not in a list of matching Mhz for memory clock 3505.

I'm not responsible if You kill Your GPU. The risk is Yours.

For a 980ti, using Quark algo for a reference, I think if one could get the memory clock to p0 7ghz, one should get about 2 mh/s more.
I was trying memory oc on my 750ti for a reference.
But being a noob at your programming layout to do this, I can't try this.
If there is a way sp or djm ect could program this into their programs, that would be great.
Or is this a one step..and it will stay that way even on reboot?
Thx
ps we still have cuda miner for special algo's.

I've tried compiling the current neoscrypt kernel (single invocation which seems to be slightly better on cuda 7.5) with cuda 6.5. Interestingly enough, it is as slow as with 7.5. Thus I'm working on the old version and managed to improve it a couple percent. Maybe I should make a new fork with neoscrypt for cuda 6.5.

Just to summarize a bit the way I do things, for me for a sell to be profitable it has to reflect, somehow,
the time I spent in coding (regardless of the coin value ) hence if the coin value is low,
it wouldn't be profitable for a miner to buy from me or it wouldn't be profitable for me to sell below my time/money equivalent  
(and would be bad business practices as well since when I work for a coin dev I charge along that time/money equivalent).

so for the moment, it isn't for sale...

also as already said multiple times: trust is important for me... (private miners are sold in priority to people I can trust)

Just wait till it's unprofitable then release it for free or for a very low price. I bet that will appeal to the majority of miners and makes sure you maximize your profits! XD

You have to consider you guys aren't the only ones making miners. Private kernels devs exist, especially for big farms. Whole reason people still mine x11.

Looks like about 250 kh/s more with my 2 980ti's and 2 750ti's rig.
Hard to tell will run it overnight to see if anything changes to that.

guess you forgot to read (as usual) what you are quoting...
if it isn't profitable to release then it isn't released, and the fast code may be eventually used elsewhere
(other coins, other algorithms) to keep the edge... hence no hurry as far as I am concerned

[induktor]

Hello!
I was reading the last 40 pages (i've been out a while) and I was wondering, why is there is so little info about power efficiency?.
isn't the most important factor in mining nowadays?, specially today that is barely profitable?
power here is getting expensive fast, and unless i found the most efficient way, i will be out of business soon!.

around august I decide to sell all my GTX 970 G1's not because they weren't fast, but because of power consumption was ridiculous when compared with the rigs using 750ti.

even now, I have several 7950 but don't use them because, again, power efficiency.

my rigs (all 750Ti) is the final result after so many buy/try/sel/buy/try/sel cycles until i finally found the most power efficient rigs possible (not sure if this is true today because of the new r9 nano card, would love to see comment about this)

so, here is my data, I will love to know about yours and compare notes!.

cards are almost all Gigabyte 750Ti (and couple of evga's ftw), stock clocks, lubuntu64 cuda 6.5 DRV 346.59 ccminer 1.5.74  (the best one so far for this config) no hard drives, os runs from 16gb flash usb sticks.

QUARK:  86.4Kh/Watt    (average card power consumption, at the wall, including %computer: 70W)
LYRA2V2:  71.6Kh/Watt  (average card power consumption, at the wall, including %computer: 60W)

PSU used, dual conversion, 80 Plus bronze at 40% load.
what is yours?.

[induktor]

Sorry for the double post but wanna keep it separated

Several pages back i read that some of you where concern about using several PSU's in parallel.

I can help, if you like, PM me, i have extensive experience doing it, i assembled a farm for a client about 2 years ago (which is still today operating) with dual PSU's, the reason for this was because my rigs where using at the time 900W at the wall each.

back then a 1000W PSU costed an arm an a leg, and even so, i will be using it at 90% capacity 24/7 cycle, not a good idea!.

not even thinking about the AX1200, which is impossible to buy here, very expensive!, but 850W PSU where cheap.
so i bought several from different brands and models, and found the proper combination.
the key is to find a PSU that regulates from the 12V line and not from the 5V, like the cheap ones.
99% of the 750W or less regulates at the 5V line and are not good.

You can see it easily by looking inside, if you see a vertical board with VRMs then the PSU regulate on 12V line, and then converts them to 5V and 3.3v this is the PSU that can run in parallel.

why?, well, if you use something like the add2psu the first PSU will use 5V and 3.3V because it is connected to the motherboard, but the second one, and this is the tricky one, will only use 12V, since 5V is not loaded (and non-VRM PSUs are not designed to be used like this) the second PSU will be unstable, and voltage will swing up and down all the time.

this is a very serious risk for the GPU because, even when most of the time the voltage swing will be within GPU VRM input specs, there are conditions when this is not the case, example a micro-power outage and during power up or power down of the rig.

i have tested this myself with proper instruments (i do electronics engineering for a living) so, to not make this any longer, the second PSU (the one is not connected to the motherboard) MUST be dual conversion PSU (with separate VRM and regulation at the 12V side).

I have seen a lot of people that trust on server power suplies but check if they really regulates on the 12V line, some of them are not!!, if not sure, tested it under different loads and measure voltage swing over time to be sure!, an electronic load is fantastic for this but i know most people won't have that, so you will have to be creative, i started testing them using car light bulbs (the big ones!) hehe.

PSU's I know do this (from memory, what i remember in the tests 2 years ago) are dual conversion and are extremely stable.
Sentey SDP850SS  <- my favorite because of price!
Sentey LTP1000
Sentey MBP1000
Sentey HBP1100
Corsair AX1200

finally i didn't use myself the ADD2PSU because it was impossible to find here, so i build it myself, it's easy, very few components, PM me for details.

[hashbrown9000]

nice to see you back around here induktor!

since Quark mining is right about at the cost it takes to mine, i only have one or two rigs going, mostly for space heaters since the temp is dropping nicely outside.

all the other algos are in the shitter. i think BTC needs a nice big pump.

Would a dummy plug (PSU tester) on the 24 pin solve the problem you describe?
