Great work
Can I ask what the power usage is after the upgrade

Here's my test rig with all modifications in place. Running a core clock of 16.384MHz at 1.25V. The oscillator is a temp pulled from what I had on hand, and will be replaced by a proper-fitting part (of the same specifications) in the actual kit. The VRM switching transistors and inductor aren't warm to the touch and don't seem to have any trouble handling the drive current. The total board metered out at 12.35A consumption off the 12V rail, which is actually less than predicted.
Also notice the added components on the VRM power rails - this reduced line ripple and parasitic switching noise substantially, which should improve the reliability of the ASIC chips.
I also added topside chip heatsinks, but it's up to experimentation to determine if that's actually necessary since by design the majority of heat dissipation is through the board. I noted the ASIC chips were warmer running overstock voltage than standard and I added chip heatsinks, but the main heatsink is mostly cooled with indirect air so better direct cooling might negate the need for these. I will not be including advanced heatsinking parts in the kit because I don't know what each person will need to fit their existing setups.
Here's a screencap of the configuration page after running overnight. It had been functional for ~20 hours steady before starting this "session". The converged data rate reported is a little higher than I had been getting in steady-state, but is within acceptable margins for accuracy.
I mine at Ozcoin; the .1 and .2 workers are overclocked USB Block Eruptors. The blade is on a Stratum proxy credentialed under sidehack.0 and is the only device on this worker. Reported hashrates have ranged between about 12GH and 18GH depending on luck.
I haven't considered overmuch the requirements for doing the upgrade as a service - it's possible for a nominal fee. I know folks aren't going to want their machines out of service for long, so depending on location high-speed shipping options and turnaround guarantees will have to be worked out with cost in mind.

Would you be willing to do this as a service too for those of us that don't have the needed skills??? Sending you a pm.

I'm putting together a basic DIY kit for overclocking ASICMiner new-version Blades (the ones without OC adjustments built in), taking the stock up to around 14.6GH.
Looking at two versions of the kit, one with just the basic parts to overclock/overvolt and one with additional power supply components to reduce line ripple and noise for more stable operation.
Neither kit will include advanced cooling options; I'll let you guys figure that out yourselves. The kits will include requisite parts and printed instructions for what gets swapped with what. This will require soldering skills.
Kits may be available by the end of this week, at least to people in the United States. Just as an initial estimate, what would people be willing to pay for the parts to upspec a standard Blade by about 35%?

The real number would depend on time to complete project, but a 20% of purchase price of a blade to get a 35% increase in performance would not be obsurd... so for a real number figure, I'd be willing to do about .20 to .25 btc for a full kit shipped. If the powerdraw doesn't increase substantially and the backplane could still be used, you're talking a gain of 40gh per full backplane, now that I can take to the bank.

need more evidence!

Stuff should be ready to ship on Friday. I'll have some pictures and screenshots up later so's to verify the numbers I'm seeing. Definitely keep you guys in the loop. Had a lot of fun hacking on the USB Block Erupters, was a bit worried at the scale of the blade but everything's working well, especially with the added VRM filtering. Might have been a fluke, but taking out some line ripple and HF noise (the added filtering quartered noise and ripple) I saw about a 100-200MH increase in steady-state hashrate, and that should also reduce strain on the chips which is nice with an overvolt.
As a note, this kit is a fixed-voltage overvolt and fixed-frequency overclock (of about 35%). But I will be working on an adjustable clock source and see just how far these things can be pushed at a given voltage, which should be fun.

I would consider this as well, for 3 blades.

That amount would get you a bulk discount, but additional (international) shipping may eat it up. Either way we'll keep it reasonable.

It really doesn't take a lot, thinking something like 0.1BTC for the base kit shipped, 0.15 for the full kit shipped. Sometime soon (it's been a hectic weekend, and will continue to be a hectic week) I'll have an actual build log posted - gotta get a webserver up first though.
For reference, the stock rates at about 10.7GH; with the base kit applied mine was reporting about 14.6 and after adding parts to the VRM output (which greatly dropped line noise) it's been reporting around 15GH (which is actually higher than theoretical expectations, go figure). Running stable for 13 hours now, no X chips and no heating issues.
That would include USPS Priority shipping in the US. Bulk orders would be negotiable, and shipping outside the US researchable.

Looking forward to this, will be a UK Buyer

good job for developing these, im sure there are some serious buyers out there
October 14, 2013, 04:25:06 PM
Kits will start shipping today, 12/18
I had enough questions from people having difficulty keeping overclocked blades cool and efficient, that I'll be including parts to run three different overclocks - the same ~13GH overclock from V1 blades, a ~14.4GH overclock and the maxed-out 15GH like the original kit. Basically just find the one you're able to keep stable and use that.
Selling for flat 0.025BTC per kit, as many as you want shipped for 0.01BTC
I'll also be offering upgrade service with return shipping and next-business-day turnaround for 0.085BTC per unit.
I also have a couple overclocked Blades I'm looking to sell if anyone's in the market. They're retailing for 0.38BTC in the group buys, I'll sell these for 0.43BTC which includes USPS Priority shipping and insurance. One's a 14.9GH, one's a 14.4GH
To place orders, submit payment to address 1EpQdQgAs2CrF2TYRTmdAasE5vQNPWwQCs
PM me with your desired shipping address and a link to the transaction block of your payment. I'll respond with a confirmation that your order has been received, and a tracking number for the shipment when it ships.
Instructions on applying the kit

More details farther down. If anyone has any further questions regarding specifics or things I've overlooked, feel free to PM.
I'm also currently developing additional overclock for ASICMiner Cubes, as well as working on standalone high-efficiency power supplies for them and other devices (including GPUs) that use PCIe 12V connectors. The next few weeks should be interesting.
