Heres is my complete setup:

AMD 1.2mhz Tbird (266fsb)
Abit KT7-A Raid
512mb PC133 RAM
Visiontek GeForce 3 Ti 200
WinXP Pro



First lets start with CPU...now on the KT133 board, the max Multiplier is 12.5 meaning this way you would only get 50mhz more, joy. Right now my PC is runing a 9x multi with 133/33 = 1.2mhz. I tryed a few settings ALL of which resulted in my PC re-booting, but I would not get a display, the monitor would come on for a split second, then go back off. (making me think some sort of safety feature in bios kicked in.) I rebooted a few times hoping bios would revert to default or somthing...but each time I had to clear the CMOS jumper to get defaults back.

This is a very common set up, back in the day (sadly only mayby two years) this board was the Cream of the Crop. (now PC133 is slow and so is a 1.2 hehe) Someone said there was something I had to do on the processor? Some pin or somthing that tells the processor to run only at this speed...I have heard of that, but though that was only on Intel chips or Slot A (sorta new at this OCing thing when the board is actualy maxed...old school jumpers with CPUs lower than board max was easy...of course this probably is too)

Ok, on to the G3...I've seen some insane clock speeds like 250/500 stuff like that...I downloaded Powerstrip 3.12 I believe, and it works fine with everything...and I start to pump up the setttings. I think Core on the Visiontek is like 175/400, I went by some of the benchmarks and settings people have here..>I bumped it up to 200/450 figuring that was low. I ran 3dMark...i would lock on only the second test...I though hey maybe 3dMark suxxors, so I ran Quake 3...I definantly noticed a slight frame, like 5-9 in high res...but about 2min into the game it locked, and occasionaly I was getting some tearing...so I was dissapointed I could clock it this high. SO I fooled around with a few settings, and finaly everything worked...the problem? I was only running about 10-15mhz higher, and my Benchmarks wernt any different.

I was reading some sites, and if you guys have some fave plz point me there. It suggested pluging the card Fan into the MB, and also setting AGP to 2x instead of 4...which to me doesnt make sense when your pushing for speed.

I R n00bi3 :D

With the video card, it may just be that you got a low-yield chip and RAM. it happens some times. Sometimes you get lucky, sometimes you don't. My visiontek ti200 reaches 230/530 (running it at 215/490), but I think I was lucky. Make sure you have good airflow in your case. If the air is allowed to sit, the hot pocket around the video card will prevent it from going very high. Do you have any case fans in the system (other than the PSU fan and the CPU fan?)

Air flow shouldnt be a prob...but I supose it good be with the card if it is getting too hot. I have a full tower case, fan bringing air in, and two Taking it out, along with Volcano cooler on CPU...there is just the stock fan on the G3. I'm going the plug the fan into the MB to see if that helps me raise the speed some more. j

Also, is Powerstrip 3.12 what you use then?

Setting your AGP from 4x to 2x does wonders to improve your video card's stability (specially when overclocking using the FSB) and really doesn't affect the performance that much. Also set the wait states for the AGP in the BIOS settings for stability.
