Check aaaaand in your A*S

after that you're coming back for more? you really wanna do it? ok, lets dance
If you burn out your 24pin connector which is common for amateurs like u
especialy for idiots, I made some additional comment earlier:
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.
-------------------------------------------------------------------------------------------------
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"
---------------------------------------------------------------------------------------------------
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*
-------------------------------------------------------------------------------------------------
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:
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.
-------------------------------------------------------------------------------------------------
but try running my rigs with 6 cards and 8-10 cores per MOBO
You lie. unless you build a custom bios and a custom kernel and be one of the few to acomplish 9+ amd gpu

It would be much better if you put them on the right
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?
-------------------------------------------------------------------------------------------------
I use smaller but copper radiators
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.
-------------------------------------------------------------------------------------------------
And if you are getting good temps on the VRM now, try mining Litecoins
not again, learn to read!
one of my 7 rig's , 1500kh :
it IS on scrypt now.

*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!
PEACE!
