300 FTC bounty for the one that can give me the best cgminer settings
-
Seems D2 takes the victory!
Pushing 1500khash extra from my rigs total.Now i just need to sell my CRAPPY XFX 7970 cards with their mesely 490khash each and change the 7970 with hw error to an 7950 (only rig with mixed cards…).
With those extra 3 7970 cards i will recieve, +two 7970 +1 7950 beeing idle i should be able to go to at least 14mhash.Nutnut im closing in ;D
-
Hmm do seem that fuzzy3 rig do not handle the new settings…
4x 7950
GigabyX58 dh3 motherboard
Intel i7 920 socket 1366
4gb memory
xubuntu 13.04
Seasonic x1250 psu
powered extenders.Any idea what to do?
This rig has done the same before when i pushed it…EDIT:
Forgot to mention, the computer does not crash, only the cgminer hard crash, so i have to remote reboot the computer (headless) -

My money is on a heat related issue. I would try setting fan speed to fixed at least 85% and add a big fan behind the cards and see if it will run stable. Ive had cg miner crashing randomly even though it wasnt showing temps out of the 70s till I put fan speed fixed to at least 85%.
[/quote]hmm you might be right.
Rotated the 420mm fan a little bit (one fan covers both fuzzy2 and three for a total of 8 cards)
Also set fan-speed to 85% damn that got loud=P, but it seems stable for now -

Anyway, try these:
…
This gives stable ~650kh on the sapphire vapor x 7950s with boost enabled. Not sure which sapphires you have.
[/quote]I have Sapphire Vapor-x 7950. This works fantastically! Thank you!

[/quote]thats what the forum is for (great D2!) =)
why not express your thanks trough here: http://forum.feathercoin.com/index.php?topic=2521.0 8)
sure want ftc to gain more ground/value -

[/quote]Woke up to fuzzy3 beeing crashed today=)
so no doesnt seem to be due to temp. everything is well cooled -

[/quote]Too much power draw from PSU? What exactly do you mean by crashed? PC rebooted or cgminer crash
[/quote]sorry bad explaining. Cgminer is completely frozen.
when i killall the application and try to rerun cgminer it just autofreeze.
not even ./cgminer -n will work.Have to restart computer for it to work again.

[/quote]And you did check with ps first to make sure it had terminated before you tried to run it again?
It kinda sounds like maybe there’s some driver corruption going on if it was actually killed. Perhaps driver reinstall might help but that’s just me trying to come up with solutions.
[/quote]checked with ps first and after. it died=)
Its a pretty clean xubuntu install that are identical with all the other fuzzy rigs that works regarding drivers=P
I do however suspect the mobo, put the config back to the old faitfull 550khash and it runs stable again=) -

I was considering buying some sapphire 7950 3l dual x cards. I only have experience with the reference 7950 4l cards. with powertune at 20 would you happen to know how many kw your 4 cards are drawing from the PSU?
[/quote]i have a 3 rigs on one of my circuit breakers, 4x7950, 2x7950,2x7950 (1xSeasonic x1250, 2x silverstone 850w) it pulls a total of 2750w at socket.
so around 1300-1400 with 4x setup. However the cards are also clocked and pushed high, giving me 650pr card! (not bad for a card that cost 300$). -

[/quote]On a 20A breaker at 110V you are only supposed to pull 2200 watts. Perhaps your system is suffering from a brownout, and the first components to go are the GPUs? Then once they quit pulling power, you are close enough in spec that the rest of the system avoids crashing, but it’s too late for the driver? Try running it on its own circuit.
[/quote]in my country we have 220/230v electrisity, which gives me 3520w on each of my 16amp circuit breakers (i have two 100% dedicated to the park, straight from the fusebox to the mining room :P)

[/quote]Might even be the PSU itself providing dirty power under those kinds of loads. Maybe too much on a single rail? Sorry if I’m making no sense, 3 days without sleeps really messes you up.
[/quote]Hehe no prob
Do not think its the psu. Those Seasonic X1250 are excellent^infinity!
also given that its 3 systems on the same circuit 2750w isnt realistic just to divide in two.
Im guessing the seasonic uses around 1150-1300 max, and thats at socket, given the power supply are 80plus gold which means 88% efficiency at 100% load it is actually only using 1012-1144w MAX on the dc side. The 12v rail is alone specified to be able to deliver 1248w of the total power.I do not think the psu is giving dirty power, it only happens on one of my 3x seasonic rigs, and on that rig its cgminer that goes to shit, system is still alive.
Those other rigs are running excellent. Also the psus are cool and do not look “pushed” at all 8)
My bet is bad mobo -
The mobo is one i got as a bonus during my previouse used gpu purchases.
It has had some strange hickups earlier, will try with windows now just for fun.theres a big chanse i just order myself another mobo, getting 400hash extra for 100$ is a steal=)
