Hi, I bought a Blade which is modified with 35v 220uf capacitor, 43k ohm resistor 0.1 +/-, 2 custom heat sinks attached on the rear of each power board, passive heatsinks on the all Mosfets and chokes.

I'm using a 750w PSU to power it as well as 2 stock unmodified Gridseed blades. I only had it running for a couple hours when the PSU shut down. I looked at the modified blade and there are scorch marks between the Barrel connector and USB port, the chip that visibly appears to be fried is the one between the USB and Barrel port labelled AFR26.

Pics of the blades below:

As the mosfets and chokes, etc all have heatsinks on them I can't see what else is fried from a quick inspection. Would this have been caused by overclocking too much? I set the clocks between 1000mhz and 1038mhz which the seller said they run stable at.

I can do a bit of soldering so if anyone can guide me on where I can get the components I can probably fix it myself. Also do you recommend I change anything else that hasn't been modified to improve it, i.e barrel connector, heatsink, etc.

Also one of the barrel power connectors from the PSU has its plastic melted slightly but the connector itself looks fine and there are no burn marks on it.

All I can say is ,,, JUNK! Why is anyone wasting their time on these way under performing stable overclocking wannabe not so well thought out or engineered rush to market quick made crap by GrimeSeed? Magic Black Smoke makers! POOF! Cheesy

I loved the 5 chippers. Had a ton of them, very stable little things. But the blades were made to run at their recommended speed for a reason! Because they are generally not stable at all when overclocked! I mean, look at the mess of junk you have to throw on them just to keep them from going in to melt down in the first place...
If you can get your money back because the seller mus-represented it as stable, do so.
Then don't waste any more time or money on GS Blades. Try the Zeus miners. Much more bang for the buck and very stable machines, at least the ones that were made and wired right in the first place when they were brand new!
If you are really in to experimenting when them, then go for it. But I think you're wasting your time.
Good luck!
