Why is it so damn hot in here?

So I snatched up an ECS P45-T Black edition motherboard for cheap.  2 16x slots, and 2 1x slots.  Throw some extenders in it, hook up 4 5870s, hook up my band spanking new Seasonic 1250, and clone over a working Win7 with my cgminer all set up to go.  Fire the bad boy up, loads up, installs drivers, restart...

Sees all the cards, fire up cgminer and..........  hard freeze.  WTF?!?!?  Bad extender?  Switch them all out.  Nope.  Tried powered and unpowered in all slots. Nope.  Bad card?  Switch all of them out.  Nope.  Bad PSU?  Switch that out.  Nope.  1 card, 1 extender in one slot?  Nope.

1 card in 1 slot, no extender.  Woot!  it's alive! 
2 cards in 2 slots, no extenders?  Yup, good to go.

2 cards in the same 2 slots with extenders?  Nope, hard freeze.


So it appears that this board is so damn cheap, that it can't handle a standard 19cm PCIe extender cable.  Fucking POS.

Anyone have any ideas before I go shopping for a new 775 motherboard?

TL;DR
Stay away from ECS boards, they blows balls.

It "could" be a power issue. Are the extenders powered?

Tried both.  Seems like it just can't read the data lanes with the extenders hooked up.  And I know the cables are good, i switched them out from a rig that has been running rock solid for over a month.

ECS was also known as PC-Chips, UMC, etc. They are a bottom tier outfit that has previously put fake cache chips on motherboards, made counterfeit chipsets, and sold motherboard/CPU combos and altered the bios to report a different CPU or cache size (and those are just ones I have had personal experience with). Typical Chinese ethics.

clone over a working Win7 

thats generally a bad idea. thyere still may be left over drivers and crap from the original mobo that is was cloned from. even if new drivers installed who knows whats left over and trying to talk to non existent or slightly different hardware.

try a fresh win install.

So your theory is that there is some old leftover driver that only causes issues when a PCIe extender cable is used?   Huh

Garbage in, garbage out.
Calling ECS stuff substandard would give them more credit than they deserve... "Fucking POS" was just about right.

There are many extender designs, perhaps some other extenders would do the job.
Still, not worth your time and trouble with 775 boards costing as little as they do now. Just grab any decent board and never look back.
Thanks for the link Deepceleron, I really enjoyed that piece of ancient history. Hey, if you can't build decent boards just make sure the labels are all in order Cheesy

Did you try jumping the two presence pins on the 1x port?

How about I just jam a quarter in the slot and call it done?

Didn't you know? You have to insert quarters to make the game load.

Burn with fire, then RMA. I'm sure they get it all the time...
