what is the replacement part for this blown mosfet again?

Is it this one? http://www.ti.com/product/CSD17552Q5A

That's what I replaced mine with yes.  It's close to the original specs, but not exactly.  I tried a couple different ones from TI and they didn't work.  The 2Q5A ended up working so I left it with that.


What happened for yours to look like that?  I tried dual mining with a 47k voltmod...won't do that again.

Just regular scrypt mining on a 47k resistor mod.

Think I'm gonna get some small heatsinks and attach it on all my seeds.

The picture above is what I found on google matching my problem but this is what happened to mine


Wow...no pinched fan cables or anything?  How long has that one been mining up until that happened?  What type of power supply were you using?  What's the ambient temp where it's mining?

Sorry for the questions, but I've got 6 that have the 49.9k/50k mod.  3 have been running non-stop 24x7 for 2 months, the other 3 have been running non-stop for about 3 weeks now.  When I've modded them, I did add some small heatsinks to the mosfets because a little extra cooling never hurts when overclocking anything.

No pinched fan cables or anything. They have been running fine overclocked for months now since mid march. Out of the 22 only this one has a burned MOSFET. So I'm guessing I had a bad one in the batch. But yeah a little heat sink won't hurt nobody hah Oh and I'm using these with custom cables to an ax1200.

Wish they would release a firmware to open up ssh so I can flash openwrt or something on it. Atleast use these as a router or something

The death of GPU's again. Lets see if they rise from the grave a third time.

What about Script-N and X11?
Are they not ASIC resistant and can only be mined by GPU.
I do not think the Lightning new miners would work on these coins?

asic resistant, think you answered your own question

This is a setup that Spotswood made for me... It wasn't quite the same as the original design, but i think it turned out pretty well



120  Economy / Computer hardware / [WTS] Gridseeds Scrypt - Case - Fans - Modded - Complete Setup - 22x on: May 02, 2014, 04:31:12 PM
Well the lease to my apt is almost up, and I need to move, so this rig needs to go. It does about ~10.5 Mh/s, STABLE!~

Specs:
- 9x - Corsair SP120 High Performance 2350rpm Fans
- 2x - Corsair H100 Radiator Fans - Moves a ton of Air, but way too loud for my liking
- 1x - Corsair AX1200 PSU - less than 2 months old, 7 year warranty still intact
- 3x - 10 port 12v Powered HUBS
- 2x - TP-Link WR703N Controllers
- 22x - Resistor modded Gridseed 5 chip miners using 47k Resistor - (I have experience with the solder iron, so they were done correctly! Definitely not a hack job you see on the forums)
- 22x - Gridseed Fans - The ones that I took off the Gridseed units
- 2x - Phobya 3 PIN Fan Power Hub - Powers all the Fans
- 2x - Custom Spotswood 80/20 Extrusion Case
- 22x - 1.5ft USB Cables
- 22x - All Custom Power Cables that feed directly into the PSU
- 3x - MicroUSB to Molex Cables
- xx - Misc Cables, screws, hex driver

Looking for 6.8 BTC SHIPPED!~ or 6.5 BTC PICKED UP - I can drive 10-15 miles, located around NYC Area.
I also take LTC, DOGE, PayPal... I accept escrow, but you'll have to cover it. I have done a lot of deals on this forum, so I have cred, just search my username.

I want to sell this as a whole, so no breaking up!~

Let me know
