260 GTX keeps crashing...

I think I'll see what the memory and core can do. If it's just the shader core that's struggling then I probably won't bother.

Though I'm not sure if the shader and gpu core are directly related to each other for performance? In Rivatuner it links them when overclocking with the shader roughly 2:1 ratio

Can you unLink them in rivaTuner, if not use eVga precision...

 

[Chong Warrior]

Yeah you can do that. I'm just thinking they'd do that for a reason is all...

Also most of the factory overclocked models seem to take the core/shader/memory up in a similar ratio to each other. Example if the core is clocked by 10% then so is the shader.

My thinking is maybe only overclocking GPU core could lead to some kind of sync issues and actually lead to reduced performance?

I'm about to put this to the test over the weekend anyway

Yep, but I find some companies apply different ratios, and going from 12:27 (or whatever) to 12:26 isn't going to make a huge difference, justr guessing, keep us posted on your results and findings as I'm very interested know...

Remember only change one thing before running a benchmark, and return it before changing another thing to analyze these effects, before building the speed up cumulatively...

Well worth downloading ATITool (if you haven't done so already) and using that to determine best clocks for your card.

When I had the GTX 280 I didn't find atitool particularly useful. It seems to work well with some cards and not so well with others.

core/shader out of sync only leads to performance issues if you force it to run outside of the normal range (usually with a BIOS edit) OCing with say rivatuner the clocks will auto correct on the card after applied to fit within the normal min/max range for the ratio.

I've read that ATI Tool hasn't had any code written into it for the 200 series of cards? I can't see any mention of it being compatible in any release notes either.

Well after some messing about it seems it's not possible to overclock them too far out of range as you say. The shader clock has to be at least double the core clock or it won't stick. So if I want a 700mhz core clock then the shader has to be at least 1400mhz, which isn't happening lol!

Have managed to get the memory upto 2400mhz with relative ease though, which is a good boost from 2000mhz
