Nice work J4! I'm impressed! So, have you decided if your rig is fully overclocked now? No more head room left? Again, very well done! Wolfey2014

So, the bridgemod ... would only bridging one of the resistor still allow voltage=1 to work w/ mining software? Thats what seems to be the case in the little guide on the smaller gridseeds. Also, in doing the bridgemod, what voltage does this run the ASICs at? Whats stock voltage again?

Stock is 1,2V and Bridge does 1,3V ; both ±0.5V CGminer voltage=1 works and sets 1.32V on mine ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fabload.de%2Fimg%2Fgs_850bpjx8.png&t=665&c=tgkbyHyy4-vCUw)

Does this .01 increase require component upgrades or just heatsinks on the fets / VRM areas? And also, which one gets the bridge to allow voltage=1 in software? rather than both for locking it in on hardware. What are ur hashrate / clock results w/ this mod?

FETs are between 40°-50°C on 900Mhz
on the pic in post#117: top one: permanent VID=1 bottom one: the voltmod

could not clock it to over 900, though
"registers write failed: incompatible firmware"

Ah bummer, well maybe its not even worth it, mine already run @ 850 / 863mhz fairly stable. Is voltage=1 the only setting or is voltage=1 changeable to a different number?

Can you check if by chance it is the top pcb that is giving more errors ? Slight overheat of the chip on the upper board gives higher error count for me.

Heads up guys.... FIRMWARE UPGRADE NOW OUT & EARLY SHIPPING DATE FOR HASHRA LUNAR LANDER. We are very happy to have just released a major upgrade to our very own firmware "CONTROLA", if you haven't done so already please make sure you now click on "Update Firmware". You should be on version 1.4.5. This is for all Gridseed based Miners, BLADE, ATLANTIS and MINI.
New updates include: More frequency options, Magic number for BLADE Clock Speed is 838. ; )
Advanced settings section allowing individual miner clock speed control.
New drop down menu for easy selection of clock speed.
Also with individual miner control features including miner serial number.
AND SOME LAST MINUTE GOOD NEWS… The early production of the Lunar Lander is ahead of schedule, yes you did hear that right… Ahead of schedule! Batch 1 will now be shipping out no later that 31st May 2014.
Perhaps this new firmware will also work well with your overclocked blades. It also may work so well that you won't even need to do any hardware mods to the blade at all. Of course, there is always room for a few more hashes..

I wonder if its actual blade firmware or .. just their dumb rpi image.

It's not firmware for the Blade. It's Hashra's own RPI image. See here to download it: http://hashra.com/support/If you run windows, just download Win32 Disk Imager. Give it the drive letter for your SD card and point it to the HASHRA image. Then click "Write" and off you go.

So these units are now on sale everywhere for about $1,100.. I'm wondering why.. something has got to be driving that cut..

I just heard the Blades are going for around $960 each and the pods are going for $65... The new A2 is being sold for $12,000... Man, what a racket! It's like the olden days when I was Mr. cutting edge! Expensive game and right now, the way things are changing so fast, hardly profitable! Sheeeeiiiiittttt!

39Kohm resistor replaced 16v 220uf capacitor with 35v 220uf ferrite beads removed heatsinks added directly soldered power cables ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi59.tinypic.com%2Fe6skrb.png&t=665&c=-UL01AUrWWrO5g)

sounds like a lot of work for just one pod more of hashrate
tried 7mh or more? are the midgets still the bottleneck?

When i got the blade it would do a 800mhz and no more.. with an average hash rate of 5.2.. and a 5% hardware error rate.
1.3 mh/s for 30mins of soldering.. which is a 25% increase in hash rate...
which is worth a minimum of 0.2 btc extra per a month... you decide if it was worth it.

ferrite beads removal and direct soldering took away 20degC of heat output on the top of the pcb. capacitor replacement and extra heatsinks is to prolong life
