dual old p4 coolers to mach gpu0 and gpu1 temps
This is the stupidest thing I've seen!  Grin
At least put them to the right where the VRMs are. I can't see if you are using thermal paste but if u aren't, put lots of paste cause the surface is not perfect, and put them on the back of the VRMs, hopefully you will see a drop in the Phase Temperatures.

Pending an RMA, and limited in my abilities to properly fix it by warranty seals on the screws that hold the cooler, I decided to keep my dead-fan 5870 mining until I get an RMA number:

It ain't pretty but it earns me right around $2 per day. The power supply is on top cuz I'm too lazy to take the one out that came with the desktop...and for air flow...ya, we'll go with air flow. The 5830 on the outside there is the main earner whilst the 7750 inside does a descent job...and runs my games. I also LTC mine with the FX-6100 cpu which is why there is the little grey fan in the front. Even with the open case it gets warm in there so it helps push the air around a bit. Hoping to add another 5970 to the mix to continue to be profitable with the rise in LTC prices Wink

Posting this mostly to encourage the amateurs out there. I don't make much with this setup but it paid for Christmas presents last year and continues to pay for my MineCraft server, my Mumble server, my website hosting package, my Rift subscription AND a few gallons of gas here and there. It's literally free money people...get your rig turned on and mine that bad boy!!! Tongue

Scared to ask questions here? Still a noob and can't post? Ask me your questions...I don't know everything but I certainly don't mind helping where I can Wink - gecko@gektek.info

I also like very much of these homemade rigs, specially the ones that do have a proper construction and not just plenty of zipties and hotmelt-glue.

Luckily GPUs will stay on mining on the scrypt side after ASICs dominate sha256 side, it will be interesting to see if BTC/TRC/PPC value increases even more and thus allows GPUs to stay longer on that side too.

DO NOT DO THAT!

You are giving those 12 volts back to the MB if you don't cut the wires!
You should cut the 5 power wires from the flat cable first, than solder additional power.

And if you are wondering here you will see which five lines you need to cut, than solder 12v to them:

At least put them to the right where the VRMs are. I can't see if you are using thermal paste but if u aren't, put lots of paste cause the surface is not perfect, and put them on the back of the VRMs, hopefully you will see a drop in the Phase Temperatures.

you dont post here if u dont know s**t!

it is ultra-super-good to sent 12v back to mobo, check pictures of burnt 12v pins @ 24pin atx when using many cards.
this is a big issue for miners.

there are even special thingies like this:

.......................................

Interesting. So, from what I see you replicated that power boost cable four times and feed power to PCI-E bus. But why four? Wasn´t only one enough?

I wonder also, is it vital to provide also the ground connection? All the powered riser I´ve seen are only using one wire (12V).

i made more that 4 of that.not all for one rig lolz. I have >>7<< rigs. some rigs do not need it, some are better with two of them like this one from photos:
super old single core only asus mobo with  pcie 1.0  and two dualcore 5970 eating some serious amps from slots.

no , ground is not crucial. since its shorted to pcie 6-pin grounds, current can go back that way. so you won't burn pci-e slot , and there is a s**tload of grounds at 24pin atx, so you won't se that burnt either . but its safer and helps a little to have it anyway.

This is where we ended up.  The only thing different right now is the way the 3 cards in the front rig are mounted and the fan us hanging up above the rigs blowing down on an angle for better air flow.  Almost every card, except one, is mining at or below 50 deg C with some pretty significant overclocking going on.  (Up to 1718 on memory)  The one card that isn't running so cool is getting taken apart in the next few days to get a good once over.  Give it a re-paste, make sure all the screws are tight on the cooler, etc.  Its only about 5 deg warmer then the others, but its enough for me to want to investigate.  I'll post up an updated picture come Tuesday when I get back to the rigs to play with them some more.

Check aaaaand in your A*S Cheesy
Never use such stupid things like:

So obviously you are not a total NOOB, but:
If you burn out your 24pin connector which is common for amateurs like u Smiley and you haven't cut the wires, you will burn your 24-pin and your PCIe slot! Did that cross your mind!
(of course this will doubtfully happen if you have modified all your extenders)
Now it is a very bad idea if you are using a PSU with multiple 12V rails, and/or depending on the Motherboard with.... omg I won't be explain this use google or something try "voltage equalization" idk how its called, English is not my native language.

IDK why are u explaining to me that modifying is a good thing. I didn't say don't modify, I've modified most of my extenders, but you should cut the wires!
With your two cards you wont burn anything, but try running my rigs with 6 cards and 8-10 cores per MOBO without modified extenders.

My burned homemade extender burned not where I modified it but where Gigabyte decided to put thinner wire,.. stupid GB. Cheesy

And about your stupid radiators on the back. Smiley
I bet they did lower your temp, its not a bad idea I overstated it saying it's the stupidest thing, but its funny looking. It would be much better if you put them on the right, or both sides!
I use smaller but copper radiators, as you don't know copper is much more heat conductive than aluminum. And if you are getting good temps on the VRM now, try mining Litecoins which you will have to soon, if you want to stay in the game. Smiley

He did that because just one wire is too thin!

especialy for idiots, I made some additional comment earlier:

Quote from: xorxor
to not make your mobo look like that [googled, not mine]:

so even idiot wouldn't assume I was the one failed so hard, but I overestimated you as one.
I have never ever killed any hardware by miscalculation of currents. I buy stuff burned like that fot 5% price, repair, mod and use it.

-------------------------------------------------------------------------------------------------

Quote from: king_pin
you will burn your 24-pin and your PCIe slot! Did that cross your mind!

no it didn't. it doesn't work like that. atx 24pin has some electrical resistance and molex has some. together the resistance is lower - so sumary heat generated on connectors is lower AND distributed betwen molex and 24pin. that is around 4 times lower per pin. [simmilar 6A per pin for pins in atx2.0 and 2 molex pins, so simmilar resistance] but its even lower in my case cause i use gold plated pins for 12v in atx. so NO if you add more connectrion you will not burn anything, not "burn more"

---------------------------------------------------------------------------------------------------

Quote from: king_pin
Now it is a very bad idea if you are using a PSU with multiple 12V rails, and/or depending on the Motherboard with....

no and no , irrelevant and irrelevant.
1 no , most [way over 90%] multiple 12V rails PSU's are shorted inside. the per-line-limit is only cause of per-pin limit. simple. you can check it with a simple multimeter
2 no , motherboard doesnt matter. there are no , ZERO , motherboards that generate 12v for pci-e from some other voltage. it would be unefficient. so you can allways short 12v's
3 irrelevant, i used  a redundant server modules with single 56A lines.
4 irrelevant, i used an old mobo with a simple no control, no fuse 12v connection from atx to pci-e

there will be some fun facts at the bottom*

-------------------------------------------------------------------------------------------------

Quote from: king_pin
With your two cards you wont burn anything

if you conect 2 5970's its 4 5870 chips and 2 pcie-briges, theoreticaly 100W from pci-e bus, but I check currents every time - and they sometimes are 150% of the theory. high quality sli/crossfire mobo could provide this power but with a risk of 24pin power connector burn [8A cards, 3A mobo -its 11 from 12MAX amps at 24pin ] but to quote myself:

Quote from: xorxor
super old, single-core-only asus mobo with  pcie 1.0

this crap wouldn't even start on anything over 4850, to high voltage drop and card wouldn't even run VRM's

so you deffinetely should use a powered riser or power-boster on good mobo, or two in my case [shitty mobo] for safety, stability and durabality.
the only exeption are boards with additional molex to pcie bus already in place.

no. it not only wouldn't rise the total heat removed from 5970 [single way air flow], but also make temp distribution betwen gpu's much worse,
and 74C + 74C is better than 75C + 45C - what would a cool gpu0 get you with gpu1 dead?

well so what. I have a big dick. does it change anything? you waned to impress someone? I use what i get, some rigs get watercooling some old p4 radiators. and actualy this particular job requires a huge contact surface and is a very low power/surface type cooling so smaller but cooper is SHIT for this use. so didn't impressed anyone here.

-------------------------------------------------------------------------------------------------

*promised fun facts at the bottom

the problem with shorting 12V lines is possible if you try to join a non-redundant type voltage curve regulators[standart atx].
you can short only regulators with guaranteed negative voltage/current curve [undercorrecting feedback], and to have a fair power distribution they should be the same type.

I do not recommend shorting a different controler outputs, other than two identical redundant modules, with exact the same workhours on them.

to join typical ATX power sources [which sometimes have an overcorrecting feedback resulting in positive voltage/current curve], you ALSO SHOULD use a powered molex, but connect them only to the mobo-powering PSU, not the GPU-powering one, to keep they 12v lines disconnected. same for true multiple rail PSU [rare] .


P.S.

come on bro, me being more educated and experienced DOESNT lower your skills!
your mods are nice, your knowledge and experience is way higher than average,
your logic is quite ok, so why are you so mad? there will allways be someone that will kick your ass, check this thread, some rigs make mine look like shit. I dont care! I'm happy to look at them. be happy for other people, dont be jealous!

This is the array of ~140 Cairnsmore CM1 boards I built last summer.  The last time I had all of them hashing on a single pool they were pumping out around 115 GH/s.  Power demand is 6.5 kW, not including cooling.  I've moved them to a better location for summer, which is why I'm comfortable posting now

When I saw Skyfall I laughed at the lame crypto gear the movie's villian had.   Grin



I'd like to give a little shout out of thanks to all the folks at BFL and especially Inaba!  Without you this would never have been as profitable as it is today.  How you might ask?  Well:

  • They took millions in preorder money that otherwise would have been spent on hashpower that exists and competes with me off the market for nearly a year now, and continue to do so today
  • They scared lots of other folks away from making the investment I did, since it was obviously a money loser when they would ship in October
  • They are so unbelievable incompetent, they still haven't shipped!  Meanwhile these babys are chunking out $600 / day
  • When they finally do ship, their incompetence means they won't ship much and it will be many, many months before difficulty catches up with my electric bill

Feel free to ignore me.
