So what about a thread of most profitable / best working pool to use with our Gridseeds?
what's working the best for you
I use coinwarz, regardless of GPU/GSD. Pool is just matter of preference.

I use coinwarz, regardless of GPU/GSD. Yes I do to, but coins there change so often, like you can check every 30 minutes and an other coin will be on top ^^ Hard to decide wich one to step into sometimes

Look for coins which have high profitability in both current and 14 day average.

It says right in the url "UNMODIFIED" gridseed overclocking.. and yes, it is true. From my own experience, 850 works great on non-volt modded units! Very stable! Volt modded GS5's can stably hash at 1150 or more with virtually ZERO HW errors! Unmodified versions cannot even touch it!

I'm so sure why I'm getting 50 HW and A:650. Prob due to heat? I'll try to apply non-conductive thermal paste and see if I can bring these down.

doge.wannamine.com works great! Also, I'm trying out www.blackcoinpool.com and I now belong to PMB Mining - http://pbmining.com?ref=btcmkr It's a great place to put your btc to work making good money instead of just sitting doing nothing! Good luck!

If not, 1150 will produce tons of HW errors and waste energy big time! The stock heat pads work just fine with proper placement and torquing of the hold down screws.

Good luck! You could have used my ref link hehe BC I'm a long time follower of that coin, tried the pool Friday but it was not a good payout, they said they made it better, let me know cause Friday I rented a rig with 5MH and got paid less than 100BC

Was your miner stable at 850MHz with little to no HW errors before you did the mod? Your soldering job doesn't look at clean or intact as it could be. Perhaps that might be what's causing your problem? Sorry I can't be of more help!

So you're saying it RAN fine at 850 / 900MHz WITH OUT the mod? Did you test it before you did the mod? This is very important! If it was unstable in the first place, then the mod may not work or might make the results worse! Please be clear and concise in your answers. I cannot help you without the specific exact data I am requesting.

Yes it ran stable up to 900Mhz before the mod. Now with the mod, 900Mhz works fine too (as expected), but at 1150Mhz it doesn't work that well. I got the Golden units.

Hi all! Just wanted to tell you of my experience in doing this voltmod.
I currently have 4 Gridseeds with the 5V fan mod running bfgminer on minepeon on a raspberry pi. From day 1 I did the original resistor mod and found 3 of them to run at 950mhz fine with no HW errors but one of them just didn't want to play nice. I ended up running that at 850mhz.
I then tried doing the 36k -> 38k resistor mod and pencil mod to the gridseed that wasn't playing nice. Found that this didn't really make a difference and I kept it at 850mhz as any higher would produce some HW errors.
Just last night I decided to do the new resistor mod. I resoldered the 36k resistor back, unsolderbridged the original resistor mod, rubbed out the pencil mod and followed the guide to solder at 39k 1/8 w resistor to r52.
This raised the voltage from 1.15v to 1.37v measured across r52 and the gridseed runs stable at 950mhz with no hw errors. I'll be replacing the resistor with smds when they arrive.
The original 3 gridseeds that ran fine at 950mhz consumed about 7w of power whereas the new gridseed with the new voltmod runs at about 10.5w. For reference, the fans used approx 1.5-2w of power.
Edit: Forgot to include hashing rate stats! about 12 hours up time: the original 3 running at 950mhz hash at 404kh/s with an effective rate (calculation includes rejects and hw errors. Column 3 of bfgminer) of about 380kh/s on avg the single newly voltmodded one running at 950mhz is hashing at 388kh/s (not sure why its reporting so low compared to others) and an effective rate of about 400kh/s
I want to thank everyone in this thread for all the information about the overclocking of these devices =D
If anyone have any questions feel free to pm me. I'm located in Australia so my timezone in out of sync with all you northerners =P (winter is coming.... )

I wonder, why do you not a higher frequency, I've just received mine and stock at 850 running fine getting about 350Kh out of it I haven't tried higer freq yet? Thanks for the update anyway ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I'll post some results when I modded mine as well. I'm using a PC PSU and better quality usb cable, the stock ones are really thin and short. CPUminer works real easy, real noob proof, using the latest version with fine tuning the freq. I'll maybe give BFGminer a try soon as it uses the same drivers. I have unchecked the fifo buffer under windows8 and all seems fine for now.
