wich algo?

[Slava_K]

Quark.
ps. Whithout extranonce hashrate now is going up. Later look on it. Whith extranonce all night hashrate is low.
pps. Stuped westhash. All time on 2 from 4 miners stratum conn is lost... restarting

[sp_]

try nicehash. Extranconce should be switched on.

[sp_]

I have found the bug now


change from &foundnonces2[thr_id][0] to &foundnonces[thr_id][0]

like this:      quark_jh512_cpu_hash_64_final(thr_id, nrm2, pdata[19], d_branch2Nonces[thr_id], d_hash[thr_id], ptarget[7], &foundnonces[thr_id][0]);

Only half of the hashes where messured resulting in a 50% drop...

[Slava_K]

Yes. Only half of hashrate... 😕

[sp_]

I submitted a fix @git.

[rednoW]

sp_, maybe you miss my previous post. ccminer continues to hash even if i lose internet connection to pool resulting in unused power consumption and heat. Can it be avoided?

[Slava_K]

Compiled. Testing.
edited. Not fixed...

[rednoW]

confirm, not fixed

@sp

Gonna set up for a couple of hours mining...what address you like on yaamp?


edit; never mind, a couple hours DASH headed your way!

edit2: hope ya put it towards some beers.

Just a fyi guys. More power plugs on the card does not mean the card will use anymore or any less power. That is determined by the core voltage. You want more auxiliary connector as it gives you more methods to supply power to the card. You can always use a four pin molex connector/adapter. I just bought a 970 Asus strix for instance and despite it only.having a eight pin power adapter it uses more power then a different brand 970 that has a eight+six adapter. This means more voltage is being drawn through.the eight pin then should be and as a.result its.triggering over voltage.protection on my psu. I'll have to change it with a dumber psu.later tonight which should be fine.

This happens at stock clocks after moving tdp over 100 which immediately triggers it. I haven't even tried over locking it yet. I am debating on sending them back for a.different model as even if I use a different psu its stressing the connector more.then it should. Having seen melted connectorrs with my 290s while mining scrypt (psus fault) its a good idea to errr on caution. This applies.to.750s as well. 

Tldr more power connectors the better.

The card is rated at 145W, the 8 pin can handle 150 plus 75 from the slot. I don't think the problem is the
connectors. I'm also not sure about an over-volt fault. If the card is drawing too much power it would
cause a volatge drop. An over-volt might be the PSU or the mains. If you're confident about the power
send the card back.

The TDP the cards operate at are also much higher even at the same voltage then the other cards I have (according to gpuz, afterburner), this very much limits the OCability of the cards as well regardless of how they're touted on the sales pages (unfortunately).

Changed out the PSU and it fixed the problem. There isn't more then one 8pin connector so I couldn't use more then one connector to split up the load.

I meant over-current protection.

Also don't buy cards with backplates on them. They sound like a great idea, but they're rarely designed well (like a heatsink) and trap heat between the card and the air around it. They don't aid in cooling and actually make things worse. I didn't see the Strix had them before I bought it.

BACKPLATES, MOLEX ADAPTERS--

I disagree with your statement about backplates, most users report cooler temps by 1-2 degrees with backplates.  And, molex adapters on anything bigger than a 750ti is asking for melted plastic and a short-circuit.  My 280x's melted molex-to-PCI connecter adapters before my eyes last year.  I am lucky to have been watching while it happened, and able to power down the rig.       --scryptr

Reverted some changes in quark and submitted another optimalization. JH512 and keccak are running in parallell, but when I swiched the order it seems to run faster. Need to verify on the pool though..

Caugth a cold. Have fever and eating pills. will be little updates the next few days..

Hope you get better soon. Thank you for not only improving the ccminer project but the community as well. Really appreciate it.

Too keep you warm I've decided to let my spare 750ti mine for you....don't expect to much of an income though because it will be active only at night or when I'm not using it

Anyone have problems undervolting. Im trying to undervolt my cards right now and it wont stick. It just rebounds back to 0 in afterburner when I click apply.

I don't think we're talking about the same thing. I'm not talking about molex adapters, rather pcie 8 pin or 6+8 pin plugs on the cards themselves. In my example the 970 only has one 8pin connector instead of a 6+8. Same watts, less areas for delivery.

I've seen reviews where they've shown the cards are cooler without backplates. They don't do anything except trap heat. Sometimes they don't even make contact with the memory, which is the only reason to have a backplate in the first place. If it doesn't make contact with anything except the screw mounts it's essentially a insulator.

In my example the 970 only has one 8pin connector instead of a 6+8. Same watts, less areas for delivery.

My 970 has 2x6 pin PCIe connections which is the same as 1x8 which is enough for the rated power
with headroom for OCing. Some 980s (165W) have only 2x6. That shouldn't cause problems for the
connectors unless they are defective. The only real benefit I see with connector overkill is offloading
the PCIe bus, a good idea in multi GPU rigs.

As far as areas of delivery there are only 2, the bus on one corner of the card, and the connector cluster
at the opposite corner. Adding pins to the connector cluster doesn't create more areas of delivery, it
only increases the capacity of the cluster area. Adding more areas requires power connectors at different
locations on the card, but that would complicate cable management and airflow.

Anyway it looks like your problem is fixed and I don't expect your connectors to melt, but don't sue me.
