8800GTX pencil mods?

[morkboy_wonder]

I just got a thermalright HR-03-PLUS for my BFG 8800GTX and have found I can't get core clock and memory over 660MHz and 1000MHz respectively. I would be interested in any pencil mods to boost the voltages (not really skilled enough to do any soldering). In terms of 8800 volt mods I have come across this hardcore approach http://xtreview.com/addcomment-id-920-view-8800-gtx-volt-mod-extreme-overclocking.html and this VR approach to a GTS http://www.vr-zone.com/articles/8800GTS_320MB_Pencil_Voltage_Mods/4641.html. Do you reckon the GTS pencil mod work for the GTX? Or does anyone know of any other mods? cheers
