Oh noes, is it an XFX card? I saw the thread about them stripping the PCB and cutting a CF connector off the board.

Well made some progress on the evga gtx260 196sp card.

Its really a tricky little beast. So that resister I changed out with at first a 75kohm one which lowered the resistance to roughly 70kohm. This helped a tad as in I could raise voltages but it would still screen out after a bit. I then slapped a 37kohm resister on there which lowered output to 27kohm. This helped alot but its still not a final finish I dont think.

Regardless Im not sure exactly what it is but over 1.30vgpu (as read with MM) and it will lower clocks in benchmarks. If I stay under that it seems to do ok.

Im testing now with the highest clock Ive gotten so far. 837core, 1674 shader and like 1300 ram. I may add that before this mod I couldnt get 750core to complete a benchmark and above 1.20vgpu would cause a screen out.

The screeching is still present but if i stay under 1.32vgpu it is relatively quiet. If I go above that it sounds like it did at stock without the cap mods running 1.18vgpu so that is definatly a plus.

I think I found some more spots for caps but Im not sure. I checked with the short function on my MM and these circled points go to the same locations that the allready capped locations do.


Oh and I would like to add, if anyone knows how to force it to run allways at its top clocks I would appreciate some help. Im kind of fighting two fronts here. One issue is the OCP which I think Ive pretty much solved. The other is that these cards when they detect instability somewhere they downclock themselves. I know you can edit the bios somewhere (hexedit basically) but everyone Ive found for these cards doesnt match my bios exactly. Also if you change in the bios for all three settings to have the same clocks it distorts the screen on windows boot so basically it doesnt like it, even with the associated votlages adjusted.

Seems I remember something about using a version of rivatuner to force the 2xx series from downclocking in 3D...cant remember which one though ...come to think of it..that might be what disabling the temp sensor does [referring to the ESGTX280 thread].

Could it be this one? I have used this in the past and absolutely loved it and it has no signed driver issues like the other editions:

yeah..2.2 or newer should be fine... I think you just need to set the "force perf level" to enabled or +1 in the adv options...

HowTo: Prevent GTX 200 Series Downclocking

Try that. The reason the screen is messed up at boot is because the card boots at lower voltages. Not until the drivers load does the card get its full 2D voltages.

I think those marked areas look good for caps to me.

I'm thinking you could just completely short the OCP mod. It sounds like another oscillator freq switch. Maybe just put a trimmer on it.


EDIT: Random thought. Considering capped a couple sticks of ram to see if they can handle high voltages for longer periods of time. DDR2 1400.....

Oooohh! Capped out mem, thats sounds good Pizza, What size caps are you thinking about going with? My Gigabyte board has 6V 560's and 100's on them now.

Off topic: Here is what I just ordered last night. I only chose the i3 to hold me off until I can save up for the i7 860. Besides the little i3 should be fun to play with in the mean time
