If it's easy you couldn't post a pic of the bits to disconnect could you? I'm ok with a soldering iron but not sure exactly the best bits to disconnect to knock a bank out.

Definitely post if you can get it back alive. I wasn't too worried about messing with mine one bank at a time because the rest were somewhat isolated from a single-point VRM failure but fortunately everything still works. Would like to see how resilient these guys are.
hmm i'll give it a go - thanks! It's certainly worth a try, it can't get any worse
Can you disable the buck IC for that bank and run it on the other 7? Probably at minimum pulling the FETs and inductor would do it, and if the other VRMs are still operational you'd be running at 88% capacity.
Or 120% if you overclocked it...

turns out the unit is no good at all 
It blew a mosfet when i first plugged it in. so i put a new one on there but it blew it again so i think the unit isn't going to work ever unfortunately.

Should be able to. I'd probably start with a 10A fuse just in case, not too far above stock rating. If that blows there's probably something fairly serious wrong with your board somewhere. Check if any of the transistors on the VRMs (the little 8-pin guys near the grey blocks) are getting hot. One of them could be trying to fail short, or not switching off properly and pulling extra power. Do any of your chips X out on the config page?
hey sorry to hijack someone else's thread but i've got a v2 blade that just keeps blowing fuses. Am I right in saying I could rob a 7-10amp fuse out my car and solder it? I wasn't sure what the ratings were with the little ones you slot in there but i've none left

I can bay any faulty asic
So SSB got back to me and told me that the new blades don't have fuses, looks like I may have fried the board D' oh! 
well that sucks, sorry to hear...
I still find it strange, that we both have "REV 2.01" but they are actually different boards.
That is not true
They have SMD R code fuse, 3A, just unsloder old and put new one.
IF you aren't able to get it working again, I'll buy it off of you. I have 2 of these green PCB blades that had the same problem.

that's a good idea putting Plastikoat inside an old computer case and then mounting the backplane.

Thanks for the advice I was just going to toss this blade but I think I will pull out the old soldering iron and see if that does the trick.
That's a great idea haven't used a soldering iron in more years than I'd like to admit. Do you have a good place where I can buy an SMD R code fuse?
The blade I just received a week and some ago also doesn't have a socketed fuse, but the "R" labeled device alongside the power connector is indeed a fuse. It's not 3A though, or someone's a fool - these blades are rated to pull at least 7A stock.
I blew the fuse on mine but didn't have any replacements, so I soldered on an automotive fuse in place and it's been working since.
Not sure if these blades are equipped with reverse protection diodes, but it would make sense - basically a diode reverse-biased on the power rails so if you ever plug it in backward it blows the fuse quickly, ideally before reverse voltage has a chance to fry anything important. If that's the case, very likely replacing the fuse (I believe the stock fuse is around 8A, mine blew after 30 hours of handling 11.4A so not sure how much I trust 'em anyway) might bring it back to life.
As for "different" V2.01 models, I think the PCB is the same, just populated slightly differently. Appears that recently they changed the fuse installation, VRM output capacitors and a few other little things - probably to save a few cents per board.

Hey I have a new question and maybe you can help
Do you have a backplane and if so what kind of surface did you lay it on, was wondering if I lay it on a metal surface will that short out the backplane.
I am use to putting motherboards on standoffs when I build a new computer rig.
Thanks again for your help

I'm running 4 without a backplane, however, I used Plasticoat and coated the entire inside of an old case just to make sure nothing grounded out. Might help ya

Ok well SSB has not gotten back to me but I think I will buy a power supply and see if that works could be that the backplane is bad.
Thanks for your help
