Am I doing something wrong here?

post #1 of 4
Thread Starter 
I just overclocked my 8800 GT (G92) from 650/950 to 720/1000 and when I ran 3Dmark I only got 200 extra marks...

I used the overclocking chart in the 8800 GT info thread for a starting point. Is this as high as this card can go or what? What should I be able to get it up to? Because I'm totally confused, I read some people get it as high as like 720/2000 and others can only increase it by like only 100mhz.

I also was looking at eVGA's product list and it says my card should be at 600/1800 stock... =/

Just seems a little odd because I remember when I OC'd my 8800 GTS it gave me like about 5000 extra marks.

GDDR3 = Graphical Double Data Rate 3
That means for every cycle, the RAM does 2 things. Therefore, you are running it at actual 1000MHz but effective 2000MHz. Most companies quote the effective memory rate.

As for your score, CPU bottleneck. Try increasing your CPU clock and see if your score drastically changes. Inversely, try dropping your CPU clock and see if your scores change much.

Wow really? Is a 3Ghz dual core just not enough anymore? I always thought 3Ghz was like best you could have until most games start taking advantage of quadcore?

1st off I replied to your OTHER post on this matter already about your score and why it is how it is.

2ndly, it's not so much that 3.0GHz 'isn't enough' in any absolute sense, but 3.0GHz on an AMD chip when running 3dMark06 using an 8800GT will exhibit some CPU bottlenecking on the graphics part of the tests (not to mention a low CPU score, which is factored into the total). Basically, this PARTICULAR test is too old to act as a pure graphics benchmark for a card as fast as an 8800GT, especially run at it's 'stock' resolution of 1280x1024.

Try running the crysis GPU benchmark at 1680x1050, with your card oc'd vs. not oc'd, and you'll see a relatively larger % increase from your overclock than you will in 3dMark06, because that test would be MUCH more GPU bound.

BTW, there is NO WAY you got 5000 more points in 3dMark06 SOLELY by overclocking your 8800GTS320. Your memory on this matter ... is clearly not accurate...
