Do Driver crashes limit O/C?

[DVL]

Hello all...

I have a BFG Maxcore 216 55nm GTX 260 and am trying to overclock it. I'm using rivatuner to do the o/c, and monitor temps, and clock speeds. I'm also using 3d Mark Vantage Pro to benchmark with.

Now I've started out just raising the core to see where I could get it maxed at, making sure the shader is double what I have the core set to. However once I get to 750 core = 1500 shader, I get a driver crash, that reverts my gpu to low power mode with a core clock of 400, and the only way to get full control of my card, i.e. clock speeds again is a system reboot.

I get this pop up in my taskbar.

Is that driver crash letting me know I've reached my o/c limit, or is this common for you've reached your o/c limit? Is it some other error I need to fix so that I can continue to o/c. My temps are fine just breaking 50c during benching. I feel like I can go alot further but that driver crash keeps holding me back!

What can I do?

It means you've gone past your limit.

Well then...

Do you think Nvidia purposefully encodes some o/c limit into the drivers?

Nope. This is an issue with your card. Check your temps, also it could be voltage related. What frequencies are you at (stable)?

Myself, I get 734 on the core, but I have no ide4a what my shader is at. I believe I brought the shaders down due to stability and focused primarily on bringing everything up to maximum performance levels... might as well oc all 3 clock rates to thier max, right?

My temps have been fine, the highest I hit was 50 c. I don't know how, or if there even is a way to adjust the voltage on a BFG card. I know EVGA makes those nice utilities for that.

Last I ran stable was 725 core, 1450 shader. 50c top temp.

So basically I have to find the highest shader figure that won't cause the driver to fail, and hope the core can do half that? Then go on to mem?
