Leadtek GF3 Ti200TDH Tweaking

 


After frying a couple of Ti200 cards in our attempt to voltmod these, we found out that maybe we should leave this to the professionals. Instead we bought a Leadtek GF3 Ti200TDH simply to see how much we could make out of it without voltmodding!! (wonder why?) The card is well known for it's overclocking features and we were pretty excited when the card arrived by mail.

The first thing that cought our attention was the heatsink, a job well done from the Leadtek engineers (really). Even before we started the real job we decided to make it a "return to sender" if we couldn't make it stable at 230/530 with it's original features.

Well that test went on pretty good, and we managed to get it rock stable at 235/540 resulting in a score of 7283in the 3DMark2001se with it's original heatsink. No other tweaking/overclocking done to the system.
Well we went on with our job, we dismantled the heatsink, and found out that the contact between the heatsink and the core could have been better. The thermo sensor was cought in the middle of them and made a good contact impossible. If the sensor would have been 1mm shorter this wouldn't have been a problem. Then it would have stayed inside the milling of the heatsink. After removing the heatsink we mounted a couple of Thermaltake heatsinks on the memory modules (of course we grinded the surface first). These were attached with Arctic Silver 3 and a drop of super glue in two of the corners. The modifications you see on the heatsinks are made due to the Koolance gpu mounting kit. We were ready to put on the gpu cooling from Koolance, added some AS3 in between them and put the card back into the agp slot.

 

Well, what about active cooling for the memory heatsinks then? First of all, find an old isa card, grind the contactor cubicles (make sure you remove them all so you don't short circuit your mainboard), make a few cuts at the bottom so it would fit into a pci slot. Drill a hole for a 80mm fan, (it wouldn't hurt to drill some pilot holes first) make sure the hole comes directly above the memory heatsinks. When you have done all this make sure the surface of the card are free of any residues
Mount a 80mm fan, and make sure it's blowing towards the heatsinks. To reduce any vibration that could occure put some rubber gaskets in between the card and the cards standard fastening arrangement. Put it in the closest pci slot and we should be ready for testing.

To make a long story short we were able to tweak the card up to an 265/583 (rock stable) when running defaults on the 3DMark 2001se. It resulted in a score of 9710
This score where achieved with cpu at 1751MHz, FSB at 184 and the memory set at: cas 2, bank.int.leave4, 3, 5, 3, 1T. We ran the tests with the 27.42 driver from Nvidia (We also tested out the27.50 and 23.12 drivers but the scores were pretty much the same)

 

Just for the fun of it we made a few adjustments and ran a test in the 3DMark2001 with the resolution set at 640*480*16, the graphics card was then set at 275/615!! That resulted in a score of 11035 At these settings and compared with similar systems (cpu 1751,Ti200,Winxp) we were able to get the score into 1. place!!
