Windows 7: Nvidia Card OCing

16 Jul 2010   #11

Windows 7 64 Bit

Hello guys,

Today I decided to start OCing ..

After doing so I found the results to be very weird.
Please view the scores.

before and after

According to the screenshots OCing has decreased performance instead of optimizing it?

@ markvis14

I thought maybe your temps were too high and the card was throttling at first glance. But looks like your temps have gone down along with your score on this overclock attempt.

Not sure but looks to me like something is throttling or maybe your power supply rail cannot handle the extra power needed for this overclock.

What is the power supply rated on your system?

Have you noticed a increase in CPU/Chipset temperatures with this overclock attempt?

My power supply is a 400W.
And how do you mean rated?

And no I haven't noticed any temp increases in my CPU/chipset

Sorry I should be more specific. Some power supply can only output a certain maximum amount of power even if the are say 400W, this is usually the case with less known brands. I'm no expert when it comes to a power supply thus I usually play if safe and get a ton of power that I will never use on my system. I'm not sure what are the required amps on the 12V rail needed for a 7600GT but when you overclock anything in the system it will usually stress out and draw more power from your power supply, not to mention add heat and stress to the component you are overclocking and the rest of your system if it's not properly ventilated. Your GPU and CPU has a safe guard against heat, if any one of those components reach a certain temperature due to overclocking or bad ventilation it will decrease in speed to cool itself down, this is referred to as throttling. Thus, if your videocard or CPU is throttling due to heat then there will be no visible performance increase and maybe even a performance decrease depending on the component that is throttling with this overclock. Really, I cannot tell but it's just my opinion on your case scenario.

you can oc any factory oc'ed card simply cause they don't oc it by much probally about 50ghz for each the core clock memory clock ect

i currently run a hd5770 i looked at the factory oc mine was oc'ed farther then the factory oc and the oc wasn't much from the normal values

i used a oc program with my nvidia 7300gt called riva tuner it tuned my agp card a little higher

and when you oc with a program it should show the limits of both clocks pretty much you want to keep under atleast 40 to 30 mghz from max for stability but it also depends on your set up the combination of board components makes for a good oc

Looks more like you have reached the limit of your card.

The heat generated is degrading performance and/or your card is throttling (as said above). There is no way to fix this except to either try with increased cooling or get a new card.

a new card would be the better thing to do you can get any dependable card for decent gameplay for about 120.00 and then you can oc that for better performance cause 9600gt is limited compared to all the new stuff going on

Throttling at 75c?
I'm gtx 480 user and what's this?

Can't you increase the threshold in bios, well atleast you can look around, get gpu-z and get your bios from you card, then get nibitor and open it, you can probably edit some voltage (possibly) and the fan settings, also you can set clocks to something higher on default.
nvflash does the flashing, can't go wrong unless you randomly change values, but those things are pretty straight forward.

I don't think even if your card goes above 80c it'd be any danger to it, you can always get new cooler, if you think it's worth it.

Also voltage is mostly restricting overclocking on older card because you can't change that, unlike in 400 series, without physical voltage mods that is.

@ Nikkeli

Look at the before and after overclocking screen shots, how could any card run cooler than stock once overclocked without replacing the stock cooler?

Therefore, a good guess is the card may have hit the maximum temperature threshold in which it started to throttle in order to cool itself down.

And thus the lower temperatures, remember this is only my opinion but it could be anybody guess unless I could see the action in person.

whats up guys? So i just got my new 780Ti finally. Im trying to OC it, but im having issues. after my GPU hits about 70C, it drops the voltage and clocks from 1.187 to 1.175 and this hinders my OC abilities a lot. i have temp target set to 82C and power limit set to 115% and neither are getting...
