10MHASH QUARK--

Mining with the release version of v46, and overclocking +100 on the core and +300 on the memory with a GTX 960 SSC, I reached 10 Mh/s with Quark:



Overclocking was done with EVGA PrecisionX 16, on a Win 7 x64 system.       --scryptr

submitted anoter 17% in skein..

27% gain total

750ti before:

69MHASH, now 86MHASH

970 before 192MHASH, now 244MHASH

nice hashrate, what about 970 and 980? they should scale better

Thanks alot.

Check out the new skein kernal. Open source and free.

QUARK HASH--

750ti FTW - 6.25-6.4Mh/s
970 FTW+ - 15Mh/s

I have no GTX 980 to test.  Others have posted rates, and I am guessing 20Mh/s with proper tuning.  My hash rates are on Ubuntu 14.04, with no overclocking, and in headless rigs.  My Win 7 system is a single card working computer.

Quark/x11 was broken(does not validate on CPU), but is now fixed. Klaus_t submitted a faster bmw, and I improved the skein launch config again.

The hash was broken. Get the latest version and build. You will get lower rates.

On my 3 card testrig gtx960,gtx970,gtx750ti

quark is up from 27,5MHASH to 28.5MHASH
Skein is up from 392MHASH to 470MHASH

I sent you, KlausT, and tpruvot each a bit.  I have to mow the lawn, I will get back to "git and compile" this evening.  I am still running the release build of v46 on all my rigs.  The release behaved well, the charts on the pool were trending up.

Please don't lower my rates...       --scryptr

I have the same issue as 5w00p on both 750ti's (Asus and Palit). PSU 1000W. The same on Quark and x11, on ccminer-1.6.2-git-tpruvot too,
but on dmd-gr algo all ok!

I think the code has drastically changed regarding the load/power consumption factors....Here are my observations about it:
- I always run binary releases from sp directly,
- on quark my miner of choice was old sp mod 3.1 release,
- have 1 comp for testing and two rigs 6x750 ti gigabytes all OC,
- 3.1 release gave me best hashrate until latest release 4.6 which gave significant boost,
- look at graph recorded with nvidia inspector, running different miners on same machine,
- each miner was running quark for about one minute,...didn't count exactly
- but pay attention to gpu load/power consumption:


gifs upload

- see how the graph on 3.1 miner is almost flat!...while newest release (4.6) is quite an improvement regarding the older (4.4)

The problem with NVIDIA cards is that they have a dynamic clockrate. If you push the card too much, it will downclock automaticly. Base clock vs boost clock. In the latest mods I have tried to reduce the number of gpu-threads to increase the boost, and reduce the power consumption.

Thanks

When you build directly from github, there might be bugs.
But it helps alot to have betatesters. 
Keep up the good work.

#46
QUARK HASH 750ti FTW - 6.35-6.6Mh/s  Showing on command window..about 1mh/s more for my rig...but at pool 1mh/s less..staying with #43 the best so far. And the 3 750ti on this computer with #46 drags down the computer.
Keep up the good work sp.
