Hey guys, two of the three spots that you pointed out Cl3p20 are good for caps. The one closest to the edge of the pcb I couldnt get any continuity between it and anywhere else however the inner most two went to the same spots as the three caps allready installed.

Found this last night also LINK I just wish they had more info on the mod. Apparently that is the resister but theres another one wired as well and not sure what thats for.

Scroll down to the bottom of that page and youll see what Im talking about.

Apparently its dinos22, assume its the same one over at XS. Shot him a pm but im not to active over there so who knows if he will respond.

You have the OCP mod correct..they simply removed the resistor and soldered the VR across both of the points. I am not sure what the third wire in the pic is for..must be vcore mod.

Quick update guys. I removed my last pic since the readings I had were off for some reason.

Basically it only goes to ground on two of the three ground pins on the power connectors so I had to get the right ones.

Anyways the risister next to the chip reads 160kohm on the volterra side and when I penciled down the resister to read about 70-50kohm I was able to avoid the ocp from what I could tell. So basically it works now Ive just got to get the right VR to put on it as with my 120fan blowing on it keeps removing the pencil mark lol.

The other resister in that pic that they have a wire soldered to I think is just for reading the resistance. That side of the resister is connected to the volterra side of the other resister so you can change the resistance of the one for the mod then use the other one to get your reading from I guess.

That is unless you have to do both resisters but I dont think thats the case.

Anyways initial results I got 810core 1620 shaders at 1.26vgpu (read with MM) and was able to pass several benchmarks without it downclocking.

Ill post more results and pics once I get all the parts to finish the job and test the various resistance settings some more just to verify that it works thru a range of voltages.

Cool findings Max, as long as your OCP is isnt kicking in then you are good, nice OC BTW, keep playing around with it and post the results

hey guys, im currently not confident enough with a soldering iron to do the OCP mod soldering resisters on top of each other(im talking about my 8800gt)

but, if all it is doing is lessening resistance, than couldnt i just scribble over those resistors? like a pencil mod?

and if so, if i put a tiny line, and lessen the resistance slightly, will that only raise the OCP trigger slightly? or do i have to measure it and get it to exactly a certain amount of resistance?

cheers

Most likely a pencil mod would work. Would need to read the data sheet to be for sure.

penciling just wont get a 1.4k or whatever resistor down to 100ohms... you can try..maybe you'll get lucky and change it just enough to help out some.
post #388 of 1497
ok, thanks, i MIGHT try it, ill see, dont wanna screw it up, its my primary card while my 4870 is being RMAd

now, on another matter, i have just been doing some 06 runs on my 8800gt 256mb, and arent sure what to do to get more points, i have my core at 876, shaders 1796, mem 955, with my e8400 @ 4ghz, and im getting 14005 3dmarks, now, how can a get better scores? is it safe to push my mem voltage any higher? its at 2.11 under load now, and they are hynix

what can i try to get higher scores? should i be pushing my shaders more? like instead of my core? or as well?

edit: just disabled physx, will see if that helps

Mod your OS, try and get a OS with as little running as possible. I had a thread on it in the howbot section.

Core is most beneficial followed by memory but core is limited by shader straps so ....

I dont know about the hynex, I was gonna ask the same question. My 9800gtx+ have samsung and they can handle 2.2 or so, atleast mine do. They oc nicely as well however my gtx260 has hynex and they dont oc as well.

thanks, rep+, ill try find your thread

so your saying that if i raise my shader, than i will possibly be able to get my core higher too? or am i just guessing wrong by what you mean with shader straps :-P
