GTX Shader Overclock

[ten80p]

Is it possible to independently o/c the shader clock or is it tied in to a ratio of the core clock ?

GTX - 575/1350/1800
Ultra - 612/1500/2160
New GTS 512 - 650/1625/2000

Wondering if GTX can be o/c to Ultra or above including the shader clock, sure I've read somewhere someone hitting 630/1500/2100 with a GTX

Thanks

Shader clock ramps up with Core speed.

You can also clock the shaders independantly using Riva Tuner if you so desire.

Yes this can be done, i used gainwards expertool to do it.

I think this is the link to the correct version

Thanks, taking the plunge on either a GT, GTX or new GTS this week, just wanted to know if the shaders could be pumped up on the GTX

8800GTX shader clock will probably reach around 1620/1680, bit higher if your lucky, not sure about the GTS but too close that gap they would need to increase another 300MHz but given the fact it's limited by memory bandwidth it might not, GT would need allot more due to only having 96sp.

The GT actually has 112 SP's.

I standard corrected, not that it matters.

Why dont it matter? Those extra SP's give it a performance boost.

That would be because what I said still stands, the 8800GT still needs to be clocked higher to close the gap due to less sp.
