CCminer(SP-MOD) Modded GPU kernels.

[tbearhere]

Well it seems the humidity at 92% was causing it. And ccminer doesn't have anything build in it to start mining again at crash.
thx

Under windows just ccminer restart won't help. Cause after crash driver goes to some recovery mode (p1,p2 ?) with very low clocks. You'll need to restart driver also or a whole system.

No...it displays that it stopped working and then I click on that it stops the display then I click on to open bat file to run and it runs at normal levels. It's ccminer that crashes not the drivers.
ps forget the humidity ..it wasn't that.

Does your bat file loop?

No..but I was thinking of doing that with a timer..but now 1  750ti  making .0012 btc a day. It was working good with r43 but.
EDIT:I think I have a card going bad not sure yet.

5.6MHASH@38W. Low clockspeed/memory speed

Is this a particular 750ti that has such low wattage? Is there some way to find these specific models? Some people in here were reporting like 68w.

Also 750tis have ridiculous overhead as far as systems go, but given that efficiency is almost double the 970s, that's a eyebrow raiser.

that's the standard wattage of the 750ti (nvidia design, not the custom ones...) if you edit the original bios that's what you will find, actually nvidia-smi, is probably just reading the bios info

I've said this before and say I say it again; software reported power consumption numbers cannot be trusted.
The smi reported 38, 45, 46 watt cap figures are not representative of how much the cards can pull regardless of having a 6-pin or not.

If Sp_'s SMI figures were correct the 750 Ti would be 48% more efficient than a 970. That is laughable. That would be 6.78 W per mhs for the 750 Ti and 10.06 W per mhs for the 970 (to be fair the 157 W is a low fluctuation and the 970 is using slightly more on average so it has lower efficiency or higher W/mhs).

750 Ti's without 6-pin, with stock speeds and unmodified BIOS with release 55 are using 57.5 watt per card which is a measured figure while SMI is showing 38W. The real and measured efficiency of the 750 Ti is therefore 10.26 watts per mhs which is more in line with the 970 as expected.

Use a kill-a-watt or a multimeter or a UPS that reports power consumption but do not take software reported figures for granted.

[sp_]

hmm. Cuda 7.5 is shit. Need to find a way to improve the AES code.

x11 is down 30% on the 750ti mining at 2Mhash. (3Mhash with cuda 6.5)

will also donate some for the improved neoscrypt miner.

also, my miners are kept in an air conditioned room set to 80 deg. F.  They don't seem to have any trouble, even overclocked, never getting above 63 C on the hottest card.

[hashbrown9000]

Anyone get this message on your wallet page for hashpower.co ?

We are short of the DigitalCash (DASH) currency. Please select another one for payments until we find more blocks.

I think I might move to FTC payouts for now.

80 deg. F. is rather hot for the ambient temp in the room. Drop it down by like 20 deg. and you'll probably see a bit of a performance boost...not to mention the room will actually be bearable to be in

[hashbrown9000]

80 is cold. it was hitting 95+ with 9 cards in there going full steam.  and the room isn't really used for anything else.

[pokeytex]

Talk about hot!!!

These are my (2) rigs in the garage.



It runs about 95 degrees fahrenheit in there but I have a big fan blowing on the rig.  ** The winter is great and cold in the garage so the rig runs very well! **



The entire rig is plugged into a power strip which is plugged into a kil-o-watt meter.



Oh and I use every available space possible for mining.  This is my office machine with (4) 750 ti's - kinda rigged :-)



Just figured I would share my set up.

That's what I thought. I use a wall meter to measure my wattage usage. It'd be weird if the same architecture and pretty much the same cards were THAT much more efficient. Lower clock speeds and memory speeds usually will save some power in addition to smaller chips which take less power, but not that much less.

Ahhh a tidy rig... Looks pretty. Closet shelving is pretty good to hang GPUs from. Little bit heavy though.

[hashbrown9000]

i do like the office pc miner!  what cards are in there? they seem smaller than even the single fan evga type.

LOL - heavy is true.  I had to add a middle support structure for the (2) power supplies , gpu's, and network switch.

They are the EVGA 750ti's SC.  Single fan and no 6pin.  Powered USB risers FTW!

Hope Djm34 will share his improvements.

please :-)

great improvement.Hope he'll share ) i'm ready to donate some bucks ))

Well it seems the humidity at 92% was causing it. And ccminer doesn't have anything build in it to start mining again at crash.
thx

Under windows just ccminer restart won't help. Cause after crash driver goes to some recovery mode (p1,p2 ?) with very low clocks. You'll need to restart driver also or a whole system.

No...it displays that it stopped working and then I click on that it stops the display then I click on to open bat file to run and it runs at normal levels. It's ccminer that crashes not the drivers.
ps forget the humidity ..it wasn't that.

Does your bat file loop?

No..but I was thinking of doing that with a timer..but now 1  750ti  making .0012 btc a day. It was working good with r43 but.
EDIT:I think I have a card going bad not sure yet.

Update
I have a card that's bad..at high room temperatures it is causing the crashing of ccminer. It's been running now at cool temperatures for an hour and no crashes.
EDIT:3 hrs now.

what's the word on card orientation? I remember reading somewhere that the specific type of fan mount on GPUs was made for the card to be in the horizontal position (as if it were installed in a standard tower desktop), and that having them in the vertical orientation (such as in your rig) is what causes the fans to fail early.

rumor / misinformation?
