Is it worth overclocking a ti4200 128mb

[malfunction]

I stand corrected. for those that want it http://www.guru3d.com/ seems to have a stock of most of the drivers released...right back to some of the really early ones!

I'm just waiting to see what I can hit with the Abit Siluro 64mb one...
Malfunction, have you had a go at OC-ing yours yet? I had a look at a volt-modding site but thats just insane!

Only just set up my PC again but it seemed stable at 300/600 - will do more testing later today.

Ok mine so far is 250 by 446. This is on a Asus 128mb Ti4200. I would be really greatfull, if one of you wiz kids could add me too msn too explain further. I also have a 2100 athlon on A7V333 Asus motherboard. When running halflife 2, i have to have it on low everything with 800by600. And also i have a tweak.cfg which pretty much disables everything in the game. Im very suprised by this so im thinking im missing something. ball.john@gmail.com is my msn messenger address. Thanks for your input

Those are stock speeds for a 128MB AGP4x Ti4200. Using Rivatuner (or something similar) you should be able to increase the core speed to somewhere around the 300MHz mark, and the memory speed will probably make it over 500. When I'm OCing a graphics card I tend to bump core speed up by 10MHz at a time, then run the car test from 3dMark '01 until I notice corruption (usually missing or flashing polygons). Then I bump it back down 5MHz and see if it's stable. Then I do the same with the memory; memory errors tend to cause coloured sparkly dots on the screen.

As for whether you can do anything with the 2100, it really depends what core it has, whether it's a Palomino, Thoroughbred-A or Thoroughbred-B chip. You can find out by downloading and running CPU-Z and then looking at the stepping code. Post back here with the stepping code and I'll tell you what you can do.

Palomino socket A
Core speed: 1735.5Mhz
FSB: 133.5MHz
Bus Speed: 267.0MHz

I would guess you are pretty limited by that CPU then (anyone remember what the pallys top out at?). Also - if it's a pally what speed RAM have you got? As that will probably be a limiting factor - you can run the RAM slower than the FSB but that will limit the benefit of your overclock. You could get a mobile XP - though they're about £65 now - and to really take advantage of it you'd need an nForce 2 mobo - e.g. an Abit NF7-S V2.0 (but that's about another £65) and faster RAM... And a faster vid card... But you might as well (if you can) save and go for a socket 939 system.

Just going to download your mobo manual now and see what options are available in the BIOS.

Right... Few things.

1) Your motherboard doesn't have a PCI / AGP lock. This means that if you overclock the FSB the PCI and AGP buses will be overclocked too. It isn't as bad as it sounds as it has different ratios it can use - to divide the FSB by to get the actual AGP / PCI clock

2) It only officially supports PC2700 (333MHz) DDR RAM.

3) (Probably most important) You've only got a palamino CPU which won't overclock that high (IIRC) and isn't unlocked (so you can't increase performance by lowering the multiplier and increasing the FSB (and so keep the same overall MHz - roughly)

There are ways around it but start with the GFX card and think about other options later on.
