G'day fellow miners!

I've been running my miners wide open with FIFO Buffers turned OFF in Windows 7 with great success!
No comm port failures. No unexpected crashes anymore.
My miners have been running stably without FIFO buffers running.

It occurred to me, based on what I've learned about comm port buffers, 16550 UART etc., that our miners do not need their data checked or routed around or delayed or moved or channeled etc. They certainly don't need any delay of any kind in their data streams between the pool and them.

So, after using various FIFO settings earlier which did increase time between failures where the miner just stops producing completed work (!yay!), looks like trying NO FIFO Buffers at all is the trick we are all looking for to keep these buggers from going to sleep on us while we are not monitoring them.

The mod that I performed on all of my miners is working great. They are all stably overclocked at 1200MHz and hashing nicely with great results pool side - where it counts! $$$$

So if your miners are still crashing, give this a try and see if it helps.
I don't know for sure, but I think cgminer and bfgminer may use FIFO's too. If they are, perhaps that is what is causing the same problem with them. Check with your local cg-bfg tech guru.

I hope this works for you as well as it is for me.

If any of you want your GS5 miners modified, please PM me and I'll be happy to help you get it done!
My work is 100% guaranteed against failure and if I do accidentally brick your pod, I will replace it at my own expense. Turn around is generally less than 48 hours after I receive your shipment.

You WILL see improved hash rates, decreased time to ROI / higher per-miner profits per hour!
I'm located in the Washington DC Metropolitan area.

Thank you and good luck with your mods!

My current peak performance figures pool side with just 6 miners...

When will you answer my PM? Interested.

Thank you for the nudge!
Sorry about that. I just returned your PM. Wink
