Building a Sossaman rig?

[Duh]

dave it is very tempting.. once I build my pending rigs I am gonna check my wallet to see if I can build one of these..

[Movieman]

Bought some silver solder ..

[D_A]

I surely hope that means something different there than it does here!

"Silver solder" here is one step below brazing on the temperature scale and requires the use of an oxy torch!

I said it wrong.. Silver solder is sort of a generic term here .
What I bought is technically 60/40% rosin core solder.
.062 diameter

Ok, taking odds..
Will it work?
Will Dave burn down the house?

[CaptMorgan]

Now i have read this thread a bit now- so I apologize if I ask something that has most likely been asked. But basically these Sossaman rigs are very basic machines with pretty good cpus- in a sense are these diskless? or are they run on linux to keep the cost down?

Of course, with questions like these maybe I shouldn't ask but, I would love to put a few together to crunch away. Though if I have some of this correctly some of the parts are hard to come by in the US.

Observing also that folding crunching data is in some aspects a small financial commitment-using the system but drawing more power than usual. Though maybe I am mistaken- am I confusing this for a small size folding farm

Are you sure you will try this? You need very steady hands

And very steady mind.

I don't think MM is thinking clearly now with March 9 coming close ...

Where is the time Dave was afraid of water
Now he's showing us how to voltmod the Sammy

"the patient is making great progress" is what Dr Sig would say

We should talk, too much to explain here.. PM me.

Resistor is off, just made up the jumper to go to ground.
Damn is this fine work and yes, I have very steady hands and working under 15X magnification..
I can read the numbers on the resistor..

And very steady mind.

Point, but this takes my mind off of the waiting.

I've learned a lot at this place from some very talented people.. Time to see if I can put some of it to work.
Be back, time to finish and then build and see if it works..

oh noes, gonna ask for the phone number I just know it

Anywhere I can find a list of the various sSpecs on these chips? I've had lots of 771 LV/ULV chips pass through my hands but usually don't deal with this socket.

@Dave: If you know of a few sSpecs (ES or release) I can try to locate some CPUs if people in this thread are interested

sSpecs list:
SL9HM -2167
SL8WT / SL9HN - 2000
SL98Q / SL9HP - 1667
SL9HS - 1667 ULV

[Movieman]

Let us know if this works, and remember, pics or it didn't happen!

Pic this!
I got the jumper to stick but then of course I managed to pull it off again..
Taking a break , that stuff is hard on my eyes.

Thanks much, I'll hopefully be able to find some. If I do it'll probably be a lot of 50 or more

There is also rumor of a 2300mhz sossaman but damned if I can find one anywhere and I don't know the spec on it..

I fear they may never have survived the birthing process.

It did exist, that company that made the box with 4 blades in it used the 2300's in their systems.
I know, I called them in Canada the other day to see if they had any left over..

now my night, assembling the "modded" sammy, pull out my PCP+C610 to install my brandy assed new Corsair 400w PSU that comes with a 24 pin and 8 pin and guess what?
It isn't a 8 pin but a double 4 pin and connectors are wrong for the 8 pin on my board..
Even the box shows a 8 pin but not inside..

I'd contact the Corsair rep here, sounds like maybe it has the wrong connector on it somehow - 8pin is 8pin I would think, so that 8 pin probably wouldn't work on any board that requires it.

yea, I sent Yellowbeard a nice note..
Didn't pull a "Corsair flucked me" post like so many do here!

[D_A]

But ... how will he know you care?

bad night, system powers up but two leds at back top have issues..
Top is red, second one down is a mix of red and yellow..
Got to find out what these represent but it isn't good..
No video..

[Movieman]

Had enough for one night..1:23am here..I think this board may be considered a $30.00 contribution to science and learning..
I'll screw around with it some more tomorrow and if no luck pop the orginal board back in..

[jcool]

Crap... try resoldering the resistor in its place and see if it fires back up?

[CaptMorgan]

omg.. this is the longest thread eVer. Well not the longest-but the coolest, most intriguing and most likely in the end result for a good cause! Had some work stuff to do and went to class late and am still reading through this whole thing- it's not like someone can quickly scroll through this, would probably miss something.

Dave I want to know what your end result with that PSU- they like a good price for product and I am getting a list together- I bid on 2 chips last night before I hit the sack. Not the best price but still OK probably gonna pick up a few boards also. "Ideally" I want to get 2 or 3 of these things running by May; they seem perfect!!

I need to go through this thread more and pull out all the necessary guts

[Martijn]

The Supermicro board did the same when I tried to perform the mod. I came to the following two possibilities:
1. Connecting straight to GND is exceeding the input tolerance specs.
2. The internal input pin pull ups are still enabled.

Either way, connecting to GND results in either MID voltage or a short, so all of the outputs default to Vref or Hi-Z instead of actual signal. That's why it never boots, it doesn't finish the loop lock.

I wasn't brave enough to hook it up to negative voltage to see what would happen.

Guys, did you try soldering a VR on that spot instead? Maybe the resistance only needs to be lowered.
