On Crypto Mining Blog Jabberwock (April 6th, 2014 at 00:46) http://cryptomining-blog.com/1839-another-new-voltmod-update-for-the-gridseed-5-chip-btcltc-asic-miners/#comment-842 measured 33k for R139 (what we call R52 for easy reference).

Thanks Zig, this might be exactly what I've been hoping for. For me, I think it is easier to add a new axial resistor than to remove that tiny smd resistor. And, it could be easily re-bridged later if a SHA coin rises to and stays at the top of the profitability lists and you want to mine it.

Ok Guys --- ZigMod is official -

R46 Pads are bridged from factory

Image from Sandor11 & edited by Zig - R46 position is the pads on the far left all alone circled in black

Now you know where it is, unbridge the solder join at the pads with either a knife or sharp blade (GENTLY) . Once the join is cleary un-bridged you may now solder 17kohm 1% 0402 SMD resistor OR an Axial Resistor.

The Above according to Zig should give you 20w @ 510-515KH.

Thanks Zig, as this is your mod (Please correct me if I am wrong)

Guys the first person to try this please share with us your results and pictures preferably comparing the old mod side by side to see if both are to 2 and the same in performance and wattage

What should be the benefit of doing it ?

EDIT: I read through some pages. Aim was to get exactly 49.9kOhm as resistor value, is that correct ?
Zig can you verify this ?

Regards.
