I am guessing you are in the Americas, if that, what is the shipping to UK and how much do you want for each?
I'm asking for 20 usd on ebay. If you grab all 12 I'll give them to you for 200 usd. I'm not sure on the shipping, I've never shipped outside the U.S. before. Pm me your address and I'll look it up. Or if you want you could send me a label. My zip code is 32205.

Or if you want you could send me a label. My zip code is 32205. In my opinion $20 per blade is quite a lot. Imagine, in the best case user can reach 50GHs per blade, for 55W (the lowest I have ever seen with that). It gives 0.0006285 BTC daily. If pay $0.1 per kWh to reach simmilar ROI to new S4, price should not be higher than $10 per blade. I do not tell about $ what user has to pay for p2102 device, PSU, cables, computer he has to use, abilities to make everything to work and so on.

so i finally got around to soldering 2 boards into one. i took off the 1st and 31st chip. so in total there is 61 chips. when i go to set freq all chips seems to report back. it hashes 80ghs-90ghs for a little and then slowly drops, it shoots alot of hw errors. im thinking its a timing/clock issue.

You are the man! Yes you are right, it is a timing issue as the timings are for a chain of 32 chips. I'd hazard a guess that if you set it to a fraction of the timing you have for the frequency you are running at, then you'll have less HW errors and a hash-rate improvement. Once again, YOU are the man and well done for taking one for the rest of us mere mortals! EDIT: Any chance of photo's of the mod on both boards? That will be super. Also, (and I am sure you can handle this), but if you want some input on the timings that you can try, could you advise what freq you are running the boards at?

i would suggest to try at half the timing your using now, then work upward with a jump of 2

Of the 4x S1 units i have, if i set timeout to 70 or greater theres no hashing and the unit beeps. 55-65 timeout is most effective for undervolted gear

@ Sobe-It: Grazie, mia S1 lavorare dal 32 Chips! (only if the -IT does not stand for Information Technologies ;-) Thank you, i measured the 0.843V and did a link between the capacitor's on the positive side, so there is no need to scratch the PWB. First i checked the volatge on the TI to not get in conflict with a internal shortcut. What should i say, it works. I also looked into the datasheet of the TI and in my case with the undervolt (Resistor add in through hole, not smt) the TI got reserve. I try to add some Pictures of it later that evening for making it easyer for all. I also think about the value of chips and the chain, i can do both Linux & Electronics, so i keep you informed. Edit: add Photo's Repair of my S1 Undervolt mod with normal resistor Measurement of current after the mod.

well, got my ant blades down below 1 W/GH
254 GHS vs 241 W :-D (5x ant s1 blades) = 0,949 W/GH

Cool ! What is the voltage and resistance ? measured resistance is aprox 1.85k, voltage 0.75ish, but each bank has been finetuned for optimal performance, so they all vary, and they run at 200 MHz with timing 60

I'm surprise you're doing better with less voltage.

Use UTP solid wire to connect and make them as short as possible. Its noise thats your enemy. I dont quarante but should improve things

Initialization of the boards look all good. Very strange. EDIT: restarted using my old command line => cgminer.exe --bmsc-options 115200:55 BOOM they all run to 57 GH/s EDIT2 : Switched for 60 ms. still around 56-57

that is strange... what are you running, linux or windows? doh, i can see that on the cgminer.exe you reported :-p do you have a linux box to test on?
