will this mod work with hashra controla?

The mod will work for any mining software, you just need to change the chip frequency.

Nervous to attempt, but an extra 100 khsh across 20 miners translates to an extra 2Mhsh. Anyone want to share any best practices aside from OP?

I did the 49.9k mod on all 14 of my gridseeds and I'm glad I did. I'm running CPUminer and all of my chips are stable at 1200mhz and up. The pool and CPUminer and both reporting very close to each other so I'm happy!!

Thanks for the follow up; can you list the tools/hardware you used and your new hash rate? Also if possible, anyone know the page in thus thread where I find the 49.9k mod offhand?

Go back to page 1, search for - wolfey2014 - all my posts will come up, and all shall be revealed to you Wink

Thanks Wolfey,

I'm still a bit confused though:

what's the better mod between these two below? The guy I have doing it is only familiar with 47k mod.

VMOD 3: (47k): Up to freq=1175 (500kH/s poolside average) 30 +/-4 watt
VMOD 3: (49.9k): Up to freq=1200 (510kH/s poolside average) 33 +/-4 watt

i have used 48k resistors (measured and selected from a pack of 5% 47k 1/8W resistors) to mod my pods and they are running at 1200MH/s with almost zero hardware errors with a power consumption of 25w~ per each measured with a kilowatt meter. power supply is a 850 silver.
i don't know who got this readings but its not consuming 30+ watts.

What controller are you using? I'm on hashra controla.

im running them on windows pc, cgminer+cgwatcher
ps. i have modified few miners with 51k resistors and they consume 28-30 watts and running at 521-526 Kh/s with almost zero hardware errors
