Hello everyone, i have been reading this thread from page 1 - 25 until my head exploded, it's definetly awesome to read all of your progress but the stuff you do is way over my limit, i know basic electronics and i just got my G-Blade a few days ago.
At stock 600 MHz it mines at a puny 3.2 MH/s (WTF??)
When overcloking to 838 MHz one blade works at a fairly low amount of H/W errors but the second one gets quite a lot of them, so i underclocked it a little to 800 MHz to make it happy, but anyway back to topic, i wanted to get the most i possible could out of my blade by replacing that lame power jack with a screw terminal (or just fuckin' soldering wires directly to the blade) and i also want to add heatsinks to all of the overheating part, my question is, that if i do all of that, will that make my miner a little more stable with less hardware errors? and also, i might just do the simple version of J4bberwock's voltage mod (just the 39k resistor) but the problem is that i definetly have the right equiptment or the money for the right equipment to do SMD soldering, so do you think a thru-hole 39k resistor will work?
Also, at some point i overread that @J4bberwock connects his miners to the 6 pin PCIe connectors on a high quality ATX PSU, and after a simple google search it seems like EVERYONE does that, is there a specific reason why?
Sorry for bombarding with questions, i'm really anxious to know what i can do!!

ATX are CHEAP !!! So that's the main reason why. But if you do have a few of those like we do. We use our own produced PSU and breaker boards which allow you to hook up to 4units to 1 PSU + Breakerboard. If you want we can post photos too.

The 12V RAIL is the key. most PSU's have a low 12v RAIL if you want to run it 24/7 go and get a Server PSU those units are build for 24/7 operation.

We sell those also at http://www.LSE.Solar
