Possible to put 3.3ns ram on VisionTek?

Well, I have been thinking about the 3.3ns ram on the eVGA cards and how they are limited by the PCB.

If some one has both the VisionTek or another Geforce3 Ti200 board that is the same as the Ti500 and same GPU?, could they not swap the ram chips and take full advantage of the ram that way?

The end result would be two working Ti200 cards but one with ram that should be able to overclock to 600mhz? Then just sell off the eVGA card or give it to a friend or something?

This is just a question. I don't have either cards. So I could not test it myself. I don't think I would have the balls to burn two brand new video cards anyway.

Nope. I can't say that I have. Aside from the pins being rather short, could you explain why it would be diffacult?

Because it's next to impossible to do and a small mistake could short the damn card and you'd be 2 GF3's short.

I suck at it, but some people are real good at surface mount soldering.. if you're confident you can do it, and can afford to lose both, give it a try. =P

it could be done, but it is very hard as these chipsh were put on not by humans, they are put in by machines and it is rather hard to solder such fine and thin pins

It would be real hard to change out the chips

they are placed on by machine, little drops of glue/resin are pre-applied that hold the chips in place. The solder is already there, then they go thru an oven that melts and bonds them. Doing it by hand would be tedious work, but not completely impossible. I certainly wouldn't bother with it

If someone would have to ask how to do it, then I would say it's not for you. But if someone has the bawlz to try it, they would probably use a hot-air part remover. You would need either a vaccum tool or a custom part of tweezers to grab the ram and pull it up without causing a trainwreck on the parts surrounding.

Also remember that with hot-air you will reflow most of the parts around the ram and probably ruin everything.

Just buy a Ti500.

2 main problems with taking off RAM chips like that:
1) solder bridges. With contacts that close together, you'd need a VERY fine soldering tip.
2) as you solder each pin, the RAM chip will continue to absorb that heat. Back when I wasn't so good at soldering, I actually caused the plastic around the pin of whatever I was soldering to melt, thus allowing the metal pin itself to come loose.

Compared to the time and effort required to do this and to buy the RAM, it would be far better for you to simply buy a GF3 Ti500.

I remember once a while back there was someone who would solder faster L2 cache chips on a Pentium 3 for a good price. It just takes a lot of time, patience and most importantly good tools for the job.

I've actually thought about doing this same mod once. I know I could do it if I had the tools for it. I've already done the core, IO, and buffer memory voltage mods on my GeForce 3. The only though part was coming up with the formulas calculating the resistance values for the voltages. That's still much simpiler than this mod though.

The only question I have is, What are the voltage values on the Ti200 and Ti500? Could be a voltage difference thats not allowing the 3.3ns chips run at its rated speed on the Ti200. If so, it may be easier to raise the voltage and see where that takes you.
