Hi all. I am using in conjunction with my 6600GT both RIVA and the included overclocking utility that came with the 6600's software.  What I need to know is will one software take precedence over the other?  Does one recognize the changes I made to the card using the other software?  Or, do I loose effectiveness running two different overclocking utilities?

Thanks.

Get 3DMark 01, 03 &05  and Nvidia Coolbits from www.guru3d.com (05 is not totally necessary, but as it is an example of newer technologies it is wise to test anyoverclocking in 05 to minimise problems with newer games.) Get these from either the link above or from futuremark


Right now to get your hands dirty! If you dont have any extra cooling in your case then DEFINATELY go out and buy as many fans as you can because the lower the case temp the better the air going to the card will be and the better the overclock will be!!

Also, if you dont know what brand your PSU is then id be tempted to go out and get a good one.

So now youve got the juice and a cool case then what else? Go for an arctic cooler, really, volts dont kill bits, frequencies dont kill bits, twiddling dont kill bits! HEAT KILLS BITS!!!!!!

Right now your all frosty inside, time to right click the desktop and click the hallowed 'clockfrequencies' tab in the driver properties sidebar (its only there once youve activated coolbits)

Now youll see 2 sliders, both of which will be greyed out, one for Core Clockspeed (the speed the processor is run at) and one for memory (the sum total of the memory frequency, ie div by 2 for mem speed). Above the sliders you'll see a dot box, check it to manual overclock, a box pops up basically absolving nvidia of any responsibility should you fry the card, yourself or any hardware by overclocking, just scroll to the bottom and click accept.

NOTE: If you havent already Benchmarked your cards at stock (normal) speeds then now would be a good time to do so, keep a note of the results for 3D01/03 &05

The slider should now have become available, so depending on your card start bumping it up, id say start with 25mhz on the core clock and 50 on the memory, youll probly have to click test changes but first adjust the 2D sliders to the same levels (use the dropdown box to see the 2D sliders), then click test settings on each of the 2d & 3D clock pages. If all go well get testing!

Run The 3Dmarks and make a note of the change (with any luck it should be an increase!) But be sure to note any corruption, freezing, artifacts or sparklies, if you get these then it is not a valid overclock because you cannot really play games (except older ones) with these problems, plus it suggests your pushin your hardware too hard.

REMEMBER! Sparklies are a core problem (usually) and Artifacts are a memory problem, so if you see any you only need to downclock the one thats causing it!

Hope this helps.

You will not get any overclocking options on default Nvidia drivers, you must download "Coolbits" (Google or Guru3D will sort you out...) , a registry tweak that enables the overclocking options.

As for Service Packs, I've found my own PC (Spec below) to be faster running benchmarks with a clean install & no additional service packs, yet quite alot slower after I've installed all of my games & SP2. This, I put down to Windows getting "clogged up", I'm sure somebody else can put me right.

The performance differance I'm talking about it small, however, certainly not noticable in "real world" uses. SP2 fixes more than it slows down, get it installed as a priority.

Current upto date drivers for your Motherboard, Graphics& Sound will always reap results.
