Or alternately these 2 points might also be connected. If you have an ohmeter and can measure it for 0 ohms that would be awesome. That would be an easier solder job for me... not so cramped.
Well I pulled my card out and decided to verify a few connection points. I was correct about the connection. The points indicated by the dotted red line are indeed connected together. So all I had to do to repair the card was to bridge the two points conncted by the pink line. I then connected the bridges to get 1.3V on the GPU core (rather than the default 1.1V).
I fired everything up and it booted to windows fine. I fired up ATITool which I use to check for artiacts. Basically I use RIVATuner to set the clocks and the artifact checker in ATITool to verify operation (too bad RIVA Tuner doesn't have an artifact checker... or maybe it does and I don't know about it...)
So at stock 700MHz everything was fine. I bumped up the core to 790MHz (a know stable core value before the mod) and after a few seconds spinning the fuzzball in ATITool the screen went blank. No recourse except to power down. This sounded like the overvoltage protection kicking in from what I have read. But I thought that this vid5, vid4, vid3, vid2 method was supposed to avoid overvoltage protection???
So I took the card back out and adjusted the vid bridges to give me 1.2V. I had read somewhere that people could stay below the overvoltage limit at 1.2V. That seemed to work better. I could get up to 840MHz on the core and ATITool was reporting no artifacts. At 850MHz I would get the blank screen. So with the core at 840MHz and memory at stock I fired up 3dMark06. Everything was fine until the second scene in Firefly forest where Twinkle-Dee and Twinkle-Dum are flying up the side of the hill and... boom... black screen. Doh! Had to power cycle again to get things back. But this time, part way into loading windows I got some screen corruption and the system reset. Had to power down, wait 2 minutes, and power on to get back to normal. (If I powered down and only waited about 10seconds the same corruption issue was still there... weird). Seems like something had to cool down???
To make a long story short I tried various cores (keeping mem at stock) and it was not until 790MHz that I could get 3dMark06 past that point int firefly forest. Funny thing was it always failed (blank screen) at exactly the same point in that bench. Even if I skipped the first proxycon (or whatever they call it) bench. Very predictable crash point but I have no idea why...
So 790MHz seemed OK. I put 3dMark06 into an infinite loop running the SM2.0 and SM3.0 tests. Wateched 2 cycles of it and went to bed. Got up in the morning and there was the black screen again.
So just to summarize:
Vcore V Freq ATITool 3dMark06
1.3V 700 OK
1.3V 790 crash
1.2V 700 OK
1.2V 790 OK
1.2V 850 crash
1.2V 840 OK black screen
1.2V 800 OK black screen
1.2V 790 OK OK for about 15 minutes. Crashed during the night.
Next step I guess is to attach a couple of wires to the Vcore monitoring points to see what my actual Vcore is and whether it shuts down (indicating overvoltage protection).
BTW during all of this my max temp on the GPU core was about 35C @ 1.3V and about 33C @ 1.2V so this doesn't seem to be a temperature issue.
Any other ideas?
