Overclocking a GeForce 4 TI4600

Inspired from the idea from the TS home page, I am curious about overclocking my 4600 (without volt-modding). Does anyone know any sites/people that could help me in this task? I am serious about this, I am not just some ***** (as dumb as I may be) who won't take the proper precautions.

Well some sites that might help:
overclockers.com
http://www.tweak3d.net/articles/voc/ (specific article)
techspot.com (if they have any info on it)

Then you have to dl a program that lets you overclock. Many programs exist, such as powerstrip lol and thats the only one I can think of. They allow you to change your memory and processor speeds (on your GPU of course). Its mostly trial and error, bump up the MHz by 5-10 then run an intensive test like 3Dmark, and see if you have any artifacts, or if it crashes. If none of the above happens you can keep going up...

Thanks Svoboda. You've saved me!

Hey great news! I managed to get an increase of 50 3D Marks in 3DMark03 from just a 12MHz increase of both engine and memory on my video card. Games also seem to run a lot better!! I definitely recommend this to all of you with a TI4600. I am not going to risk taking it any higher without additional cooling. My results are as follows:

default :1618
raised 2MHz :1613
raised 4MHz :1616
raised 6MHz :1630
raised 8MHz :1643
raised 10MHz :1651
raised 12MHz :1665

Bare in mind that I had a lot of applications running in the background (same ones each time) and used the 41.09 detonator drivers from nvidia. Not bad ey?

big increase... ;o i had a 150 mhz increase on my gf3 ti200 (memory clock) and a 70 mhz increase in my clock speed... i think youll be able to pump that more =P

Impressive, do you not have any exta fans/heatsinks attached? I have to be careful not to raise anything too high, I'm not in the greatest financial way at the moment. What would you say is a safe increase without extra cooling?

Yea you should be able to get much more out of your GF than 12 mhz. I don't remember the exact specifics of my overclocking experience iwth my 4200, but it was at least 50 mhz on both clock and memory.

Post your default speeds (ie proc - 275, memory - 300) or whatever, and then we might be able to recomend some safe high speeds. By the way, what brand is your video card, and does it seem to have a high quality fan/heat sink on it?

Well, seeing as most cards come with a very cheaply made fan, I wouldn't OC at all until getting a better fan. That is just my opinion, though I do tend to try to keep everything more cool than necessary, rather than push my luck with the shoddy quality of an HSF.

My default speeds are:

memory: 648MHz
engine :300MHz

It is an OEM package, I believe it is VisionTek. The fan appears to be quite good quality as well.

my gf3 ti200 is a visiontek as well... it has stock cooling (cant take off hs on visiontek cards, they are glued on)

I'm quite sure that my fan can be taken off, are you sure it's not just a GeForce 3 thing?

Yes, I was right, I just checked now and it looks like it can be removed. I would have a closer look to be sure, if I could actually get my card out! Its super glued in there (not literally). Does anyone have any ideas on how I could get my video card out without ripping my motherboard out at the same time?

Um yea AGP cards can sometimes be quite hard to get out. Just turn the case on its side, with the computer off of course, make sure your grounded, and grip the card firmly with both hands. Use strong force but not excessive you'll probably not break it.

Oh yeah, make sure you take out the screw holding in the card and the monitor cable in the back.

Yes you can take it off. You must carefully pry it off.

Okay, I finally got my card out, and the fan can definitely be removed. I'm not taking it off until I have a replacement though (in case I can't get it back on). Does anyone know any places to buy a good cooling system for my GPU? If only I could get the FX FLOW! That would be nice.

This one looks really nice here

Taking the heatsink off a graphics card is very simple. Put it in a sealed plastic container, and pop it in the freezer for an hour of so. This will make the glue freeze and become brittle, so easy to pop off.

And personally, id recommend the Zalman Heat Pipe for the cooling, as your not going to get much more out of that graphics card with better cooling. Your looking at maybe 30mhz core, 70mhz out of the RAM, tops.

So this thing will keep it cool enough, and is passive, so cuts down on those annoying noisy fans

Zalman Graphics Card Cooler

Thanks for all the help. I think that the Zalman Graphics Card Cooler and the one StormBringer described as really nice are the same. Will these heatpipe coolers keep my card as cool as a water cooling system? Because I was thinking of purchasing one if I can find one that's not too pricey. And one more question, will I have to remove the fan from my GPU in order to install these heatpipe coolers?

Yer you will have to remove the fans to install the heatpipe,

...now its going to be nothing compared to watercooling! But there is no point in simply watercooling a gfx card...only look into it if you are considering cooling the whole system!

Hmm, sounds very appealing!! But I'm affraid the budget won't allow a fully water cooled system at the moment, it's either going to be the NV30 or the heatpipe. (NV30 will get better performance than a water cooled 4600) In the end, I will end up buying the heatpipe cooler; and about a couple months after the release of the NV30, buying that . Man that card is hot!
