Ocing A Evga 6600gt

[deagle86]

In my current system i have a evga 6600gt. I recently bought a Zalman VF700 cu cause i was tired of the noisy stock fan. I was wondering how easy it was to overclock a video card and if in ocing a 6600gt would i see a noticable difference (in games such as BF2) or should i just leave it as is and not even take the risk.

one of my friends said all i needed was a program called coolbits, but he wasny sure exactly how to do it.

just get Rivatuner, enable overclocking, if your card comes at 500/900 start with 550/1050 and see if it will run 3DMark 05 without artifacts, move up from there, 600/1200 is not unheard of, especially with good cooling

[deagle86]

ok so this might be a stupid question, but what are artifacts, and what is the purpose of 3dmark 05? also will the free version work or will i have to buy it?

[swifty11212]

artifacts are wierd lines and graphical corruption. the more you see the more its letting ya know your pushing it too much.

[apostolics]

its free thats what we all use. and artifacts are when the screan flashes . you will notice something is obviously wrong. u will see lines and weird patterns. its agp right cuz last time i checked zalmas cga cooler didnt work with pcie cards

[deagle86]

No its a PCIe, looks like ill be taking the zalman back and getting an arctic cooler that will actually fit since i havent actual put it on yet. So all i need to do is install rivatuner, and from some screenshots ive seen, slide the speeds up in small increments at a time, running 3dmark05 in between checking for screen flashes and graphical corruptions? also, is this just gonna be a waste of time or will i notice a differnce when playing games such as battlefield2?

[swifty11212]

you should notice a diff, and run 3dmark03 too. and testing for artifacts can involve playing games too.

ok, one last set questions someone can hopefully help me with. Is there a certain ratio that i need to keep the core and memeory clock speed too (stock is at 500/1000), and do i change them under lower power 3D or performance 3D (do i need to do anything to 2d)?

 

ok so i just ran it stock on 3Dmark 05 and got 3500. Is that good? cause i dont exactly know what it means. only thing i know is the higher the better. Also, how do you determine your temp during load, and what is a relatively safe temp to operate at?

when you overclock, leave low power 3d and 2d alone, you change the performance 3d. using riva turner hit hardware monitoring and make sure it starts recording temps. not bad score.

so here are my results after i installed the zalman vf700 on my evga 6600gt PCIe:

I currently have it OCed at 570/1070 with idles temps of 44-46 and load temps of 57-58 degreess.

 

3Dmark 05: 3732

3Dmark 03: 7093

 

should i go further with the overclock or am i pushing it as far as it will go. Because i really dont wanna burn this one out and have to buy another.

your 3dmark03 seems way too low for that OC. My 6600gt, stock, with a p4 3.0c, got 8000+. OCed at that level, I could get around 9000. You have a very small memory OC, so try raising that.

the 3dmark05 score looks right, using my 6600GT at 600/1200 scoring 4114 as a reference, feel free to overclock until you start to see things you didn't see before, when you do, hit the ESC button to stop the benchmark and lower clocks by 5-10Mhz, then run again, going over for short periods of time wont hurt anything
