So I ordered Thermalright 12.8 Wm/k pads and changed everything.
Front with heatsink: 66x12 1.5mm (I'm changing to 2mm), 100x10 2mm (I'm changing to 3mm as it barely touches), 10x47 3mm. The pad attached to your main radiator (100x10mm, 2mm thick) wasn't touching and I ran out of 3mm pads, so just added another 1mm strip on top of it.
Front without heatsink: changed the one on inner radiator to 300 or it wasn't touching.
Backplate: My card has 0.5mm thermal pads covering capacitor rows. I've changed these strips to 1mm.
Can you please let us know how many packs of which size you ordered? Thank you much!! |

Since two days ago Z9 Mini is -Sold Out- so...
What's the next step of Bitmain?
Release a new batch of 'Z9 Mini' cheapest than 850$?
New batch with the same price?
Not sale 'Z9 mini' again?
Equihash miners went up in performance so fast, it probably doesn't make sense to sell the Mini again. I bet they switch to only selling the big Z9 (against the A9 ZMaster and others) and competing on hashrate+shipping-volume (where Bitmain can throw miners in the mail for buyers faster than anyone else). That's right. A9 right now makes <$50 per day and will drop more for sure, so what is the chance for Z9 mini in next month? I still see $53/day. My Z9 mini is still making ~0.11-13 ZEC a day (it was making ~ 0.15-0.16 ZEC/day in June) How are you seeing $53/day? at .13 ZEC a day at today's ZEC/USD that would be about $18 before electric costs? |

Marrs, that's exactly what I ended up doing, just playing around with the engine clocks to see where the sweet spot was at. I had thought I found the right settings at about 975 engine and 1600 memory clocks, but after about 20 minutes or so the screen would go to a solid color, which I take it to mean the card had 'crashed'. I figured the memory clock was just set too high and dropped it back down to 1375, of course my hash rate dropped quite a bit, so I started slowly raising it again, eventually coming up to 1425Mhz which is apparently where the best spot for my card is at. I let that run all night and no more lockups and the hash rate is right at the 650khash/s range with nothing else going on with the system. If I open a browser (in typing this) I saw the hash rate drop to 622khash/s, so I bumped the memory a little to 1440Mhz and the speed came back up into the 640khash/s range, which I'm happy with as long as I don't have any more lockups. Thanks for the explanation crazyates on the internal latencies, that makes sense, and saves me from searching.  |

I've always heard that hitting good numbers mining LTC was a lot of playing around and now I know everybody was right.
I think I may be able to do better but following everyone's advice I played around with mem clocks and settled on 1.6Ghz, engine running at 1Ghz and I was getting around 540khash/s. I did the calculation on that and then set my engine down to 965 in CCC and my hashes instantly popped up to 634khash/s average. No idea... I have no idea why the engine running slower would make it hash faster, I'm sure google would turn up something if I really wanted to know.
I'm going to continue playing around to see if I can tweak any more speed out of it. Thanks guys!!

Set your memory clock as high as you can get it without crashing, set your core clock at (memory clock * 0.605).
I tried setting this, 1375 *.605 = 831Mhz on the engine and my hashes dropped to about 420khash/s, re-upped to 1Ghz and it's hashing at somewhere between 480-500kh/s.  |

Watching this with much interest as on my Gigabyte 7970 clocked to 1Ghz engine and 1,375Mhz on the memory I'm only getting in the mid 400's.
cgminer as follows:

"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "0",

I can play WoW while mining on a Gigabyte 7970. I do have to lower my intensity to somewhere around 2, sometimes less if I'm doing heavy graphics stuff. Skyrim is another matter, will crash the driver every single time if I try to run it and cgminer at the same time.
I'm currently running the 13.3 beta driver.

Whut?? Padding my post count so I can post outside the Newbie area? Nonsense!  No really I've done a LOT of reading here, I'm already over the 4 hour marker, nearly 5, but I wanted to post in the thread the author of akbash has about an issue I ran into, so here I am posting away... |

Interesting idea... as the ASIC's come online the difficulty will get higher and higher to compensate, which will make GPU mining a thing of the past unless there's a very cheap alternative to the power grid. If the ASIC's really launch en mass I can see GPU mining being a thing of the past much like CPU mining today, the cost of the equipment wouldn't ever be paid off. Only novelty farmers I would imagine.

Thanks for those, good reads!

Never tired one out, but looked at them... I think I'll keep my (VERY) hard earned BTC...
