Hi, I have a GeForce4 Ti4200 128MB. The core clock is 250MHZ and memory is 446MHZ. What should I overclock it to? If you have a GeForce4 Ti4200 128MB please post up your clock speeds.

you can overclock as much as you wish, as long as you maintain system and video stability... just clock up by a few mhz each time to figure-out what your top core and memory speeds are... you can use the manufacturer's OCing utility or something like RivaTuner

As high as you can dude, you will notice quite a big difference at 300/600. thats a nice increase. 300/650 is the default speed for a ti4600. let us know how you get on..

I have a LeadTek model of that card, and mine is flash written to 275 GPU and 510 memory. Leadtek makes exceptionally good cooling solutions.

275 is exactly 10% up from the default speed of the core, and the same level as the 4400, and 510MHz is about the memory speed of the 64MB version of the 4200 (that speed is 514)

General rule of thumb, you don't want to overclock the core of anything (be it a CPU or GPU) much more than 10% Memory overclocks a little better. Unfortunately the 4200 models with 128 VRAM use lesser quality RAM than the 64 meg versions (this is to keep the price lower). I believe the access time for the 128MB version is 4ns (nanoseconds). Regardless of heat, 4ns can only go so high without becoming unstable, that is why I don't go above 510 with mine.

I got a PNY Verto GeForce 4 Ti 4200 with 64 MB of RAM. I was able to overclock it to 270/550 with no problems. I will go higher when I get some better cooling. Good luck!

I got it up to 284/555MHz with watercooling on the GPU. And with some backcrad cooling and voltage mods I hope I can reach 300/570 MHz.

My dual-PSU PC is so powerfull that the neighbourhood dims when I turn it on :eek:

My 64MB Abit Siluro Ti4200 can go up to 300/600 but I keep it at 285/585...not to stress it so much and since nothing much can gain from that speed...
