what is the proper launch configuration. ?
Boost the coreclock to 1600MHZ, reduce the memory clock (500mhz). And run without any parameters.

But if you set the settings manually the same for both miners your miner is slightly faster, and then slower than free

Now you should set the clock to 1600MHZ +100 more. (for a 6% boost). It should work fine in my miner, but perhaps crash in his miner.

In my version cards MSI gaming I can't lower the memory frequency, it is fixed on 3005Mhz

It should be faster - we already know that SP tweaked the default intensity in his miner. That doesn't mean that the comparison is fair - to make a fair comparison of the miners and the kernels, the condition should be the same. Lets say that SP's miner run by default on -i 25, so should be the intensity for Alexis78's miner when comparing. If I'm not wrong in the same conditions (same intesities and clocks) Alexis78's miner are faster on vcash and decred.

the only fair conditions to compare miners is at the same power usage. at the end of the story, it's efficiency that counts, not "maximum speed". so just set a low tdp and see which one is faster.

I'LL BACK THAT-- It is based on the economy of mining. Variations in code may require different command-line tweaksfor best hashrate, but this proposed standard is based on the bottom line. --scryptr

But If my version can run stable @ 100mhz more, then my version is 6% faster. And if my miner can run stable and fast with -i 31.9 and his version is crashing, then it's not fair to compare both of them with -i 25.

Not if you downclock the memory to 500mhz. Less power.

Not if you downclock the memory to 500mhz. Same power.
then my assumption is still correct: if you run on low tdp, you can compare fairly. a power reading at the wall can confirm.

Yes, For algos that doesn't use any memory, you can maintain the speed with a lower TDP.

Variations in code may require different command-line tweaksfor best hashrate, but this proposed standard is based on the bottom line. --scryptr i cannot agree with that ... in MY mining - i disregard the power argument altogether ... as i dont tweak or manipulate ANY of the power settings ... ever ... i dont oc either ... speed of the hashrate and its stability and its share acceptibility and correctness with the pools is all im after ... the way to maximize coin income - is through hashrate optimization and accepted shares ... if power efficiency was a factor in the speed calculations and results - then we would never be able to have fully optimized algos ... yes - algos CAN be power efficient and have 'higher' hashrates than 'standard' released algos - but not at maximum optimization ... and IF algos can get the same hasrates at a lower power usage - then why not ... but thats not what teh whole issue is here ... its raw hasrates - regardless of power ... its like saying that feul efficiency IS the factor in high octane drag races ... its not - its the time it takes to get from one point to another - and the fastest wins ... period ... they dont care how much feul or noise or rubber is used or destroyed in the process ... same here ... to hell with efficiency - i want max hashrates ( and we are talking stable and accepted shares ) to maximize the coinage ... #crysx

Yes, For algos that doesn't use any memory, you can maintain the speed with a lower TDP. I tried all the kinds of algo and all have better power efficiency on P2 and low TDP. Much higher. The income depends on your margin, but I doubt you'll make more money by overclocking. Unless you run on free electricity, of course.

its like saying that feul efficiency IS the factor in high octane drag races ... its not - its the time it takes to get from one point to another - and the fastest wins ... period ... they dont care how much feul or noise or rubber is used or destroyed in the process ...
that's because they have a wide margin. everybody must take expenses into account. if you made more money by lowering your TDP, wouldn't you do it? do the math and you'll see.

But when decred came out, my private kernals where making $10 a day with the proper launchconfig on the 980ti. and the powercost was $0.5 (5%) Pallas, did you try to overclock the core and lower the tdp at the same time?
