CCminer(SP-MOD) Modded GPU kernels.

[djm34]

On a related note, I am I bit concerned about the miner on non-750Ti cards. I'm getting pretty much zero rejects and exactly as many blocks as you could expect against the current network hash rate on my 750 rig, but a fair amount of rejects (but not 100%) on the 970. Can't see any particular reason why the same code would work on 750 and not on 970 though. It is a mystery. Just seems bit odd that near all the rejects I get are on the 970. Could be coincidence but I can't help but wonder...

I don't believe I had any rejects on your original spreadminer on my 970s.  Seemed to work with the same consistency as 750s for me, unless this is newer code you're talking about.

Talking about the original, yep. Oh well, maybe my 970 is just jinxed

register pressure can do that at some extend.
I had a similar problem with a previous version of keccak and compute 5.2 where none of the hash were getting validated due to some bad allocation (The content of the register wasn't what it was supposed to be... and the problem wasn't showing at compile time...)

tsiv,

I get 100% rejects on my 970 with your miner when finding blocks.

Have since day one and never figured it out. The 750ti's does fine though.

tsiv,

I get 100% rejects on my 970 with your miner when finding blocks.

Have since day one and never figured it out. The 750ti's does fine though.

a quick fix would be to recompile without compute_52 (if this is related)

[chrysophylax]

wow ...

is it just me - or is it that you guys seem to be working together ANYWAY? ...

why dont you merge all the work that you have been doing ( yes i know - easier said than done ) and just work off one fork? ...

seems that each of you awesome devs can bring their own thing to the table - and improve ccminer to an unprecedented level ...

just my observation here guys ...

i know if i could employ you all under the one roof - thats exactly what would happen ...

#crysx

Because then people would get his Spread miner for free?

not necessarily wolf ...

same situation applies - band together and make a private 'short' period for donors to the devs ...

a dev pool if you will ... for a short period of time released only to the donors - as with the current sp spreadminer ( although i cant use that one as its not linux - but beside the point ) ...

seems to work ...

release 2 is sent:

-2 bugfixes in the hash(hopefully no rejected blocks)
-Added another modded kernal. More hash
-Improved the default launch config for 970/980 cards. (they where way off).

best results without the -x parameter.

Since there is no cpu verification, should be tested before deployed.

I still didn't receive spreadminer, I sent you my mail this morning in PM.

[bathrobehero]

I found a block with release 2 and at +160 mhz core I get around 1760 kh/s per 750 Ti. However for some reason both spreadminers exit whenever I find a block so I have a loop. It says "Thread 1 found a solution" then "First nonce : x" and closes. Says exactly the same if a card crashes, but nothing is crashing when a block is found.

Nice, testing already, we have similar results now.

Is Release 2 ok?

Average (or what it looks like) on EVGA 970 SC  +100 core
tsiv - 4400
sp1 - 4500
sp2 - 4600

Still testing to see if and when it will find a block.

sp_ r2 is not working, I've got a lot of boooos...

reverting to tsiv's miner....

[antonio8]

I am getting all rejects also with my 750ti with version 2.

Same here

[frazier34567]

Dropped down to one 750 ti card running sp_r2 spreadminer. but it can take up to 40 hours to find a block with one card.

[AliMan]

Are any of you guys running the new miner on Windows 8.1?

[jpouza]

Are any of you guys running the new miner on Windows 8.1?

Yes.

Are any of you guys running the new miner on Windows 8.1?

Yes.

I get this error when I try to run it:

0xc000007b

Did you ever encounter anything as such?

[bathrobehero]

I got 4 boos overnight and 1 yay yesterday. http://pastebin.com/fCHuLxAm

[sp_]

Sorry guys I got a boo as well. Will merge one kernal at a time, then let it run overnight to see if the block is accepted.

im just watching for now sp - not testing for the moment - as linux is the only os i will be running for the miners ...

you always do a great job - so ill be interested to see how it pans out ...

tanx mate ...
