CCminer(SP-MOD) Modded GPU kernels.

[Amph]

so this mean that they are even worse with tlb trashing, because they should at least match the 970, instead they are mining at 60 speed

For GM20x and GK110. GM107 and GK10x already have issues in Win7. Who knows what they did with GP10x..

Like cbuchner rightfully commented in the nvidia forum thread about this issue, we should be allowed to get exclusive GPU access with direct physical addressing.

faster on cuda 6.5. Slower in cuda 7.5

As soon as I put that card into the rig its core clock reads 1519 the other 1492 and it will mine for a few seconds then drivers crash not ccminer. I tried every combo I could think of. Thats on any algo. I'm thinking of putting it on this computer and take out 2 750ti move them to the 970 rig. As soon as I can. See if that works.

There is not a single gtx 970 card that have a default boost clock of 1519 or 1492 that I know of. You must be overclocking.
Different algos can be clocked higher.. Decred can mine for weeks at 1600, but quark cannot. My 970 g1 gaming is clocked at around 1390 for quark on the default clocks. The hashrate is around 18.4 with sp-mod private #5

No that card is 1519 stock no oc'ing. That is what I read on gpu-z so when I run it at stock clocks crash. No oc'ing on anything. That is what I don't understand 1519 wow.

Probably their bios has been flashed!
Or your driver is crasy.

I don't know  . But direct physical addressing would simply eliminate the need for a TLB. It would probably be a pain to get working on different types of hardware, but as somebody who seems old enough to know a bit of 68000 or 6502, you'll get the idea

More useful would be support for larger TLB page sizes. WDDM 2.0 even has builtin support for it, but I haven't figured out yet to what extent this is supported by Nvidia drivers: https://msdn.microsoft.com/en-us/library/windows/hardware/dn894180(v=vs.85).aspx

With tlb trashing the dualminer will mine more decred. =)

Yes for gaming going to call gigabyte again about this. 2 bios for that card.

Wondering if it's worth waiting for AMD Polaris before upgrading

Hellow world
I repiar my home PC!
Swap burned (all by my wife...)  intel Z68 MB to Z170, cpu 3770K to 6700K, psu ocz 1250 to aerocool 1200.
I AM ALIVEEE!

No, if you wanna mine ether

When you finally release it... Still waiting... DCR still devaluing.

DCR is dead... ETH is strong call to bee second crypto after BTC!

it's just because of clymore, and no demand, if demand rise again decred will return to its best price, now it's all about etheruem and lisk, but wait and see

Trying to mine with myr-gr and release 80 gives
[2016-05-12 10:08:39] Stratum difficulty set to 1
Cuda error in func 'myriadgroestl_cpu_hash' at line 322 : unspecified launch fai
lure.
There http://crypto.office-on-the.net:12351/static/

PC1 - win7 x64, 1x 750Ti - driver 361.75 - works
PC2 - win8.1, 2x 750Ti, driver 361.75 - the error above :/


PS: damn it, the error was due to -i 22
removed -i - it works

Any hint how to see the default value of -i ?

Check the source code:

   uint32_t throughput = device_intensity(device_map[thr_id], __func__, 1 << 20);

The default intensity if I'm not mistaken is 20.

Or you can check the GPU memroy usage with gpu-z or something without the -i parameter then check it with a specified -i parameter like -i 18 and see if the memory usage is lower or higher.
If the memory usage with -i 18 is lower then without -i then the default -i is higher. If you reach the same memory usage then you have found the default intensity (doesn't work for algos with very little memory usage).

Any hint how to see the default value of -i ?

If the default runs (ie no -i), turn on the api feature of ccminer, and then check the api with command "threads".

any hint how to use API? never even tried it...
just point my browser to api port ?

API DEVELOPMENT BY TPRUVOT--

The API was refined by tpruvot.  He documented it in his CCminer releases.  CCMonitor uses the API, also.  Read the documentation included with those softwares.

Basically, you can use Putty to get single-response text answers from CCminer on the API port.       --scryptr
