If you want to mine lyra2 checkout cpuminer-multi. I get higher hash rates on my i7-4790 than a 750ti.

what hashrate do you get? ...

#crysx

Default 7 threads @ 115 Kh/s each on i7-4790k  @ 4.3 GHz. Best performing cpuminer/algo combination
I've found and the only one that beats a 750ti, or even comes close. minerd/x11 is a very distant second
at 8 x 85 Kh/s (minerd defaults to 8 threads). I think lyra2 is a very challenging algo for GPUs.

Edit: I should qualify this by saying it's the best free cpuminer/algo combination. I have no knowledge
of any private cpu miners.

thats pretty good for cpu ... so i must agree that it does perform quite well ...

but that cpu ( from memory - too lazy to check ) also chews almost 90W of power ...

the gigabyte 750ti oc lp max is about 40-60W and does a little over 660KH on lyra2 with spmod ...

cost wise - at around 3 x the price of one of those cards ( basing it on australian dollars - but should be approx worldwide ratios ) - the hashrate doesnt play well ...

but then again - thats if you are ONLY mining ( like we are ) ...

still - quite impressive for a cpu hashrate ...

can you still use your computer when all 4 cores are at full pace? ... or does it slow down to being almost unusable? ...

btw - where is the link for the software? ... github link? ... miner settings that you use also please? ...

tanx ...

You're right about the power but if you really really want to mine lyra2 I think CPU is the way to go.
If you're GPU mining, lyra2 can't compete with any of the other algos. You can also CPU mine lyra2 alongside
GPU mining a more profitable algo. CPU mining with n threads can affect ccminer so I usually use
n-1, which just happens to be the default. Other CPU intensive applications like compiling are obviously not
advised but casual desktop use is still reasonably responsive.

I occasionally fire it up if lyra2 is paying unusually well but not lately with the way quark is performing. What's
with the order prices on nicehash? What could they be mining at those prices? I've seen that kind of activity on
nicehash prior to a coin launch but it usually only lasts a coule of days but I haven't seen any new quark coins
in a long time. And this has been going on for over a month but accelerated in the last couple of days. Even
yaamp rentals are paying higher than any of the coins in their pool.

Wheeew! Just tried Lyra and my vid driver got blown outa da water!! Anyone got some rough seting for Lyra2RE?

LYRA2--

Use a low intensity setting for Lyra2.  Using "-i 16.5" with  no other performance switches works for my 750ti SSC cards.       --scryptr

Thank you

i have to admit that i was using higher figures than that ( -i 23 is max but many cpu validation errors ) ...

-i 22.5 was the main setting - but -i 16.5 seems to do a similar job - if not better ...

this is for the gigabyte 750ti oc lp ...

I give up...all I know is that it works. Here's a great question; since all these new mods have been introduced, is anybody gonna take the time to update a readme file so we know wtf is going on /w the new switches?


edit; if the readme had some suggested parameters would really rock.

Tell ya what...if I get help from this forum, I'll do it. If everyone would test 1 or prefer 2 algo's and just send 'em to me /w what card or cards they tested. And if the devs will send me what the new switches are, what they do, etc., I'll take the current readme and compile a new readme /w a git posting. I could even add it to the .zip, I think. I know zip will allow adding a file so...what do ya say...anybody in for this? Like a concise version.

Good idea but I'm not sure the ccminer readme file is the best place for card specific data. The data will have to
be maintained as new cards are introduced. If ccminer development slows the data wil become obsolete pretty fast.
There is already some very obsolete information in the readme and help referring to coins that are long dead.

What you're suggesting sounds like a small database considering the number of algos times the number of different
cards. Even within one model and board manufacturer there are several variations of memory and clock speeds.
Keeping it out of ccminer allows it to be updated independently of ccminer development.

I suggest starting out by compiling the current data and posting here. If you or someone else feels ambitious
they could put it in a database and put it up on a web site.

Well, as long as the forum helps out it really wouldn't be all that hard to put it in a spreadsheet type of thing. But that's going very deep. I was more or less looking at updating the readme that's with currently. It doesn't have to be exact. And be put in a concise form, similar to what is there. Get rid of the old crap, add the new mods, switches, etc. and a short form of, not recommended or highest, but starting places for people. EX. What just happenned to me...give me a rough idea of where to set a card for Lyra2RE......edit; we could easlier lowball  the numbers. Even newbies know this is just a starting place, not all emcompassing. (fat fingers..lol)

Agreed. The readme could contain some generic recommendations such as how the amount of memory, overclocking or
other factors affect the choice or parms and which algos benefit the most from which parms. Newbies should probably
stick with the defaults, I believe some defaults are tweaked automatically for each algo. perhaps SP could chime in with
his thoughts.

I don't play with these parms myself so it may be a bit hypocritical of me to be so opinionated but I just thought what you
were proposing was too much for a readme file.

ICO? Not even once.
So I'm actually curious why everyone talks about the TDP slider all the time. Why would it matter what the TDP slider is set at? It should just be set at the highest value just like with AMD cards. It wont use more power unless you turn up the mhz and even then it'll eventually crash unless you add more voltage. It just seems like a unnecessary variable as the TDP slider doesn't really increase efficiency if you decrease it as it will decrease your clockrates too, unless I'm mistaken.

What's the point of using the TDP slider over clocks/overvolts? Is it just my card that has a unlocked voltage modifier?


A extra six pin power connector doesn't necessarily mean it uses more power either. It can have a power connector and have lower core voltage, but uses the connector for cleaner power delivery instead of trying to pull everything through the bus. If it has a higher TDP, that also means it has higher core voltage, although it's not a absolute unit of measurement as each unit can be different (between bioses and versions).

To my understanding the TDP slider or power target limit is a hardcap on the maximum power the card uses. That is not necessarily translate into watt used by the card. The fans, the memory and the core itself all have to be collectively under the limit. If the limite is reached, you can't increase the clock speeds with overclocking because there's no power to do so. That's why you could reach higher core overclocks if you downclocked the memory in Kepler cards (probably applies to Maxwell as well) because then the memory used less and of course the fans can't get limited in power.

SP-mod release 50 Mining quark

The non powered

http://www.gainward.com/main/vgapro.php?id=926&

Draws 40-45 watt. and does 5750Khash on standard clocks.

the powered (6 pin)

http://www.gigabyte.com/products/product-page.aspx?pid=4948#ov

draws 60 watt and does 5550Khash on standard clocks.

But if you reflash the bios to the black edition, the hashrate is 6100 and with overclocking I can reach 6500. (The gainward is not able to reach these speeds because it needs more power)


so 1 MHASH more with 15-20 watt more consumption.. But if you don't overclock you loose the 1MHASH

Those figures cannot possibly be right. The Gainward card you've mentioned also have a TDP of 60 watts regardless of 6-pin or not (source). The PCI-E slot can provide 66W alone (5.5A on the 12V rail and 3A on the 3.3V rail). Additionally 6-pin can provide 75W and 8-pin can do 150W. The 38.5W TDP figure from the BIOS doesn't mean what we thought it would. Non-powered cards can pull 60 watts as well with stock BIOS. I both have ASUS and MSI non-powered cards and they do pull 60W. Besides, wherever you look even gaming benchmarks show close to 60 watt usage for all 750 Ti's.

Increasing the TDP should have zero effect for stock clocks, all it does is give headroom for overclocking. And in my case at least, overclocking is always more efficient as in it always scales better than power consumption. For example +150 Mhz on the core is 12% gain in hashrate and 11% increase in power consumption at the wall for x11, and it's +10%/+7% for quark and so on. Conversely, with downclocking the efficiency gets worse.

So I'm actually curious why everyone talks about the TDP slider all the time. Why would it matter what the TDP slider is set at? It should just be set at the highest value just like with AMD cards. It wont use more power unless you turn up the mhz and even then it'll eventually crash unless you add more voltage.

in general, overclocking should bring better power efficiency, unless its effect is counterbalanced by automatic or manual overvolting, or by additional power draw from the cooling system (fans).

So with all this going on with these 750Ti cards, I take it that ovr clocking is the best thing to do? BTW, I just wanted to check so I pulled the cover, my card ASUS GTX750Ti 2g is the one /w the 6pin. I'm gonna guess that's makes up for a power drop from the dual fans? (I have seen what look like short card 750Ti's on fleaBay /w one fan). I don't have an accurate meter to do any testing on it. This card also seems to be hardcoded for automatic, BIOS voltage control. It fluctuates /w 1143mV being top range. I've tried AfterBurner and ThunderMaster but you still can't do anything about voltage control. I just ignore that setting (it don't change a thing) /w GPUTweak. I still get close to 6.5 /w quark and ~3.44 /w x11. I haven't tried any other, not sure if it will mine another coin.

Oppsss...got off topic..backup. OCing is best? There's the question.

Thank you

ps. This card was pretty cheap too...$89 on...I think it was newegg, but that was a while back.

It's not a bug. It was implemented in such way by sp_. He tries to fix sum bugs in -g mode with this trick ... but for now -g mode has no pros.

I forgot to add the idle watt. The card use 7-10watt idle..

I have implemented --gpu-memclock and --gpu-engine parameters in ccminer now.
Will messure the watt and get back to you.

now THIS is watt ( pardon the pun ) we have been waiting for Wink ...
