I am currently getting 551GH/s noncerate as a type this on my full rig. Running R02F at 1.2k, small heatsinks attached to the back of each board, 6x 120mm fans split on each side of the rig, 2x 200mm fans on the top of the rig.

The chip temps all seem to be in the low 50 C range or lower.

Good to know that 16 overclocked board can function well together. Thanks

I have two cards doing 66 GH/s. I cool them with a 6" AC fan, 0.35A@110V, 200+cfm. Works very well. The 12V fans were not able to cool the cards.
For the full kit, my plan is to have 3 AC fans, blowing 600 cfm at them. Probably an overkill, but the cards will stay cool. No heat sinks.

How did you mod the cards? 66GH/s without heatsinks sounds great, I'm currently just at 60GH/s after pencil modding R02F resistors to 1.18k.

I did the pencil mod. One card has two bad chips running at 0.2 GH/s nonce rates. The other is stronger, pulls ~35GH/s.
Together they run ~66GH/s nonce rate. EMC rates are 68-75GH/s, not sure why.

The AC fans make a big difference in cooling (blowing from the back of the rig to the front)

BTW, the whole setup (2 cards+fans) is pulling 88W from the wall.

To keep this cool, the simpest method is using pump, radiator , tank and cooking oil to maintain the working environment as the system is not so complex, which will be broken if the forked coin cannot be mined efficient.

I wonder how my router would react to the oil leaking trough the network cable.. and how the pencil mod would work under it. But I would love to see someone do and report on this method.

This is achieved by penciling the recistances to about 1.1k, adding heatsinks and fans. Im still struggling to keep it cool enough during the daytime.
Once I get the cooling figured out I will once again proceed to optimising the error rates.

What effects are you seeing when the cooling is insufficient? I have one board that autotunes itself to 0 and back to 30GH/s all day. I am wondering if my cooling fan is not enough.

I am was seeing a single chip dissapearing, always the same chip and signifigantly lowered hashrate which could most likeley be accounted by the regulator overheating.
Atm it looks like I have cracked 70Gh/s for good with two boards and I might see additional imrovement once my Arctic cooling F14 fans get here (just ordered). They seem more suitable to cool entire h-boards than the slightly too small F12's that i am currently running.

BTC Mining Hardware, Trading and more

I have offered small heatsinks here a few weeks ago- but have none left-
If there is interest I could order some more ? I offered them for about 0,1btc per 16 small sinks excluding shipping (shipping was about ~0,05)

But as this is not really a profit based thing, I would only order again if there is interest from enough people on GB basis.

^That looks good

what sort of heatsinks, tiny individual ones or larger plate(s)?

Individual small ones some aluminium some copper. I bought everything that a local web store had in stock so I didnt have the luxury of being picky. I'd say the lighter aluminium ones, with larger surface areas seem better.
[edit]
I'd love to hear of a store selling suitable heat sinks for bitcoin, anyone got any leads to share ?

If I had a full kit, I would be past that with a healthy 10% margin:

Once I get the cooling figured out I will once again proceed to optimising the error rates.

Sure,

you have [board:chip] on every line and on the board chips are numbered from 40 to 4F beside each chip.

Chips start in the lower left corner, connector facing down, go up, then down, then up, then down again reaching the lower right corner of the board.

spiccioli

I can confirm that this is correct in identifying missing chips, where as the running numbering is not.

the first chip on my bad board is much hotter than the other chips. maybe the first chip is bad. i'll try doing solder bridge, hopefully i don't need to cut traces.

EDIT: welp i shorted the solder jumpers and cut the traces...the first chip is still REALLY hot, but at least the board gets detected now. i might try to desolder the first chip with a hot air station since it is apparently still consuming power.

goxed, you cut the traces on a couple of your chips...do those still heat up?

Has anyone had an Hcard that doesn't get detected? stat.json doesn't list it at all.

I had 1 card that went out like this and now I have another one....the chips still heat up, but chainminer just doesn't detect any chips. I've tried plugging it into other Mboards and it still doesn't get detected . In the past, reseating this Hcard after a few tries magically made it get detected again, but not this time. Undecided
