GPU just got finished running looped 3D'06 for 1hr @ 725/1548/1200 full Q features enabled.. stock voltage of 1.19v for GPU and 2.15v for vMEM.. its just fine..my garage still stinks like charred insulation though. lol.

nice speeds
lol at the smell, i know how it smells, pretty awsome if you like it...

Still have to add a few caps and pots but thats for tonight. Trying to see how far this will OC on air (stock cooler atm, vf830 later).

Its a good start, like the caps, nice work

@ Martkilu- once you get your heat figured out for your soldering..slamming those caps right on the PCB will be a cake walk. IMO- wires are convenient to use..but be careful with length..we cannot directly measure the effects of the added inductance to the PWM circuit...but everything on paper says it can produce negative results.

Cant wait to see some results!

Soldering job is only so-so I'm afraid but first time with the "tinning" which was infinitely helpful!

Never thought they'd hurt, I'll prob solder directly on then next time
Running ATITool's scan for artifacts atm, 4:00 mins in at 690 core, 1500 shaders, 890 mem.

I was extremely surprised the caps didnt blow up when I first turned it on Even more so when it actually loaded stress test xD
If it's 15:00 stable then I'll validate (5Mhz up it hits an error or artifacts after ~8 mins).
After I validate I'll put the pot on
Thanks soo much for your help so far everyone

Edit:
Well it's stable for 15 mins, but load temps hit 107c for the last 30 seconds so I might wait to get my 8800gt back (friend borrowing it, I'll use the cooler off of it) before I push a bit more. I'll still get the pots on tonight most likely though

It can be somewhat intimidating at first but youll get used to it. Looks like your starting to get the hang of it already. Looking forward to the final results

Yeah much more confident in soldering skills now, gunna be tricky doing the pots cuz the legs are so thin and close to each other. Most likely going to order a new soldering iron this weekend, looking at reviews atm.

You can use the wire leads for the pots..because you are just dealing with resistance, and not current...only wire leads on the caps are considered "less than ideal" but some instances warrant them..like space requirements..installation issues etc.

nice job btw..half of modding GPU's is pushing your 'comfort level'

Interesting.. Learning more than I would have imagined when I first started thinking of vModding on my own. At first I was going to just send CL3P20 my 8600gt but then thought I should try and learn it and well, its a lot of fun when it doesn't blow up xD

Is 1 Farad a significant boost over a 3900uF cap? I found 2.5v 1 Farad caps on ebay for somewhat cheap.

Edit: Expensive but there's also a 10 Farad cap

Edit 2: I'm asking because 1uF is a millionth of a farad IIRC, and

so wouldn't this give it a significant boost?
