Since this thread has to do with the gen2 BE blades and since those blades are not supposed to be overclockable I was wondering if anyone has attempted to overclock one.  I remember reading a thread somewhere where someone was developing an overclock kit BUT I seem to have misplaced the link to said discussion topic.  Any help finding said thread would be mucho appreciated.

That's actually attempting to sell overclocked blades. The thread in question, regarding kits, is here.

Anyone interested in an open-air case for ASICminer blades?

Each blade is secured to the tray via a custom plastic bracket.  The beam that the brackets and fans are attached to could be mounted on the opposite side.






Any comments/suggestions?

p.s. Does anyone have an accurate drawing of the backplane mounting holes?

I do have a pretty accurate (low-tech) method to transfer mounting hole locations:

  • Attach normal standoffs to the board.  In this particular case, the six mounting holes around the perimeter and the two (?) down the center.
  • Place a bath towel on a hard surface.
  • Place poster board on top of the towel.
  • Press the board with the standoffs down onto the poster board.
  • Label a reference standoff location, relative to some landmark on the board!!!

That should leave accurate impressions of each standoff in the poster board.

Open air case for blades. YES PLEASE! Shocked

Maybe a small 12 port or similar Ethernet switch and cable loom. Grin

Awesome!  But, I might be getting a board shipped to me pretty quickly.   Grin  I'll be sure to let you know if that doesn't happen.

ok thanks!

with the server power supply mounted and the slots filled on the backplane  it just seems like something to support the blades and that psu would be a wise investment.....

The full set up is a little flimsy due to the weight.  But if you keep it on a large flat surface with psu backed up to a wall or board, it's fairly secure.

id rather not have a 1000w psu backed up against a wall just as a safety precaution...  and i was planning on having about 10 backplanes full and hashing away... some type of open air case/tray is preferable

Interested. My biggest concern is that 1000W PSU that I have plugged into my backplane. Right now, it is supported by the wall, i.e. leaning against the wall. Really a bad solution but I have no other options. If you can add a frame around your open air case to provide support for and securely prop up the PSU, I'm in.

Also, maybe an option to have a push/pull fan arrangement, so fans on both sides? A fan exclusively on one side of the blade may not be enough. My blades run very hot.

In friendly cooperation with highend-computer.de (the point of contact for powerful,
water-cooled Silent PCs), we can now offer water coolers for the blades, manufactured by ekwb

I'm glad to see that you are thinking about doing this!  But any case I'd use would need to accommodate the HP server PSU mounted on the end of the backplane.  Your design doesn't seem to allow for it.  The PSU is tall and top heavy and needs something to hold in place so it doesn't wobble too much if you breath too hard in the general direction.

Yep, the final product will have support for the PSU. 

All I need to know is by how much the PSU overhangs the backplane and the dimensions of the PSU itself (in millimeters, please).   Grin
