Overclocking my 8800 GT only gave me 200 marks...

post #1 of 6
Thread Starter 
I just overclocked my 8800 GT from 650/950 to 720/1000 and after running a 3Dmark test it only gave me 200 extra marks at a 1680x1050 resolution...

Kind of disappointing after seeing how my overclocked 8800 GTS 320 gave me 3000 extra marks after overclocking it...

There are two main reasons for this:
1) The 8800GT maxes out the FPS capacity of your processor in 3dMark06 a bit more than your 320 did.
2) The 8800GTS320 (and all the G80 cards, really) reflected % increases in overclocking with % fps increases more linearly than the g92 products generally do. Personally I suspect this comes from a combined effect of already-higher clocks with a lower ROP count vs the g80 cards. Lower memory bandwidth may also come into play in some cases, at least to a small degree.

What you're seeing is not at all uncommon, bottom line. Having an overclocked core 2 duo or quad would manifest itself in larger changes to your score based on your overclock, because as I say, you are going to be getting some CPU bottlenecking on that test with your processor and an 8800GT.

Just you you know, the common bench for everything is at completely default settings (for 3D mark 06).

So would I need a quad core processor to get rid of that bottleneck? And if it does how much gain in performance would I get in games? Because right now I don't even think its worth overclocking my video card if it doesn't even show any difference =/

no you won't need a quad. The 6 serious will be more than enough

The problem is your overclock won't give you that much performance gain at that resolution due to the limitations of the card itself.

Try benching it at default settings, then overclock and try again. The gain will be much more significant and comparable to the rest of the community.
