The 14.9 has been running in my backplane for a couple weeks, the 14.4 was a fairly recent purchase and it's only got a few days runtime on it. These sell in Group Buys for 0.38BTC plus shipping, I'd like to get 0.43BTC for these. It's a 35-40% speed increase for 13% price increase and that includes USPS Priority shipping with insurance; for an extra 0.015BTC I can ship it Express (1-2 days) insured.

I'll include adapters to pull power from PCIe 6-pin cables. Overclocked run a little hungrier than stock blades (135W vs 85W) so make sure to keep them cool. They've got the full workup though, including chipside heatsinks and modified stock heatsink to improve heat dissipation, and extra capacitors to help clean up the voltage regulator output voltage spikes and ripple.

I will also have kits available in a few days for DIY overclocks; parts are on the way (https://bitcointalk.org/index.php?topic=310752.0) if anyone's interested, and I can do upgrade service on blades for other people with 24-hour turnaround.

What does the wattage look like and temps for Overclocked v2 blades.

[sidehack]

The 14.9GH market 11.3A when I metered it, not sure on the 14.4 but probably proportionally lower (same overvolt, lower clock).

As for temps, I have no empirical data. A 120mm high-CFM fan from the side and a 92mm high-CFM from above are enough to keep 3 of them running at above 99% efficiency in my current setup.

What kind of service do you offer for upgrading blades? Do you use escrow as insurance for item? And what's your turn around time?

pjcltd - PM sent.

BigJon - I offer 0.085BTC for parts, labor and return priority shipping. Obviously for a large set a bulk rate could be negotiated. Typical turnaround is 24 hours - I had one lot of 4 come in in the morning and ship out that afternoon, but typically I receive in the afternoon and ship out the next afternoon so everything gets at least 8-12 hours of testing for stability.

I haven't used any escrow, just took it on trust and haven't let anyone down yet. I can ship with insurance, and I guarantee that if I destroy your Blade I will replace it out of my own stock as long as stock is available, or purchase you a replacement ASAP.

Blades have been sold and shipped. I don't know of availability on more overclocked blades, but I will have overclock DIY kits available to ship most likely tomorrow if anyone's interested. Parts for 13GH, 14.4GH and 14.9GH in one kit, including additional VRM output capacitors for clean power and chipside heatsinks for better cooling. 0.025BTC each, plus 0.01BTC shipping for as many as you want. I have about 20 kits not already spoken for.

Upgrade service is also available.

I have a few overclocked Blades for sale again, looking to get 0.3BTC apiece plus a bit for shipping. Total of five available, all running about 14.5-14.6GH 99+% in my current setup.
