new build 39 GTX 750 1480core/1567mem testing with --cpu-priority 5 on yaamp: rates in khs qubit: ~4350 quark: ~5650 fresh: ~3450 x11: 2859 x13: 2248 x14: 2214 x15: 1937 lyra2: 862 sha256 ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) : 193950 (didn't wait for yay's ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) ) keccak on NiceHash: 150mhs Good rates for a non TI card. I think the kernals needs to be finetuned for each algo. When I set optimal launch configs in the quark kernals it slows down the the x15 since they share kernals. I might need to duplicate kernal calls to be able to tweak the optimal hashrate for every algo.

For both R38 and R39, 750 Ti get error "Cuda error in func 'x11_simd512_cpu_init' at line 634 : out of memory." when running x11 in HamsterPool. No such error with x11 in YAAMP.
Edit: Upon further testing, running up to 3x 750 Ti has no error (i.e.: only 4x and beyond get the above error). To run 4x and beyond, I have to use -i 18 to run fine. Error could be unique to HamsterPool only.
Edit2: 'x11_simd512_cpu_init' <-- corrected

hmmm, 750 without Ti works fine on hamster. Maybe you should try to play with --diff parameter.

Good job!
ccminer r39 on 750 Ti at +150 core and stock memory solomining to avoid vardiff fluctuation:
fresh 3770 groestl 8200 jackpot 5900 keccak 170000 lyra2 713 nist5 9900 quark 6100 qubit 4780 s3 9400 x11 3150 x13 2500 x14 2450 x15 2120 bitcoin 216000
spreadminer v5: 1730
On a sidenote, starting ccminer with --cpu-priority 5 sometimes freezes the PC without ever starting hashing so I'm not using it and I manually set the process priority to realtime after it started.

My GTX 780 limited to 80% power core 1097 mhz / memory 3100 at hamsterpool :

after new case and better cooling i might test full speed its limited to run maximum temp of 70c now pretty darn good speed already with so much limits oops lol different ccminer lol the new 39 crashes

I get this error sometimes too on rigs with 6-7 cards, or with a 960 card. The default intensity is a bit high. Ho ever if you restart the miner it usually works. It seems like the driver is freeing up som memory when the out of memory exception is triggered. Workaround: Restart the miner a couple pof times until it starts, or lower the intensity. -i 18

Your card is compute 3.5 and this miner is compiled for compute 5.0 and higher. You will have to compile a version yourself. (change compute version in the project file to 3.5) But not sure how fast it will run though...

My mod will work, but I didn't compile it for you card in the exefile. This is a maxwell mod, and all the improvements are only tested on maxwell cards. I don't know how the performance is on older cards. It's probobly slower than the other ccminer forks.

thanks man keccak is faster by 15000 to 17000 khash on 970 from realase 38, thanks for advice you give me a week ago about crashing driver but nothing worked i think that mjollnir algo is broken in all ccminer realases for 970 not just yours. I have only mjollnir crashing and few other people from this forum pmd me that have same problem all of them have 970gtx.

Tonight I will try to use the BFI instruction to modify pointers, I will allign sharemem to 1024 bytes boundaries. and insert the 8 bit offset in bits 2-10 directly into the pointer.
Today a byteperm+shift+add is needed to calculate the sharedmem adress (echo/shavite) Hopefully AES will be faster.
3 instructions down to 1 instruction.
In echo alone there are 5120 random sharemem accesses. If this works, 1 round of Echo(hashalgo #11 in x11) will use around 10240 less instructions to do the same work. IMHO massive improvement.
In my bitslice groestl improvement i removed around 1000 instructions and the x11 hash got 50-100KHASH faster on the 750ti. With 10 000 instructions removed, perhaps 500KHASH faster is possible.
But I assume 32bit pointers, so it might not work on 64bit builds. And it might not work in cuda code alone. Perhaps I need to rewrite AESround function to asm. And the BFI might be slower than other instructions, so less instructions but more expensive instructions.
anyway. will try it out.

did you check how much memory is being needed for this, could it be the 970 mem limit at 3.5 Gb? The 980 has 4 gb besides that there is not difference between 970 and 980 i think besides the 980 has more cores still waiting for my watercooled 980 to be delivered

Sorry sp_ for hijacking this thread but need to ask you and djm34, what are those algos that benefit from vram --> 2GB. And also, why some algos get a boost from memory oc and most don't? Usually it is all about core clock, you can heavily downclock memory to save power and there is no difference in mining performance. And if that 2GB doesn't matter what is holding back gtx 960 vs 750ti? On djm's neoscrypt miner 960 does +100% against 750ti, on other algos most of the time the difference is somewhere in +60-90% area. Sorry guys, computer enthusiast without coding skills just want's to learn...

#39 less hashrate on most algos. I'm still using the best one #33. But keccak was 162,000kh/s now with #39 170,000kh/s. 750ti.
