I believe all GF4TI cards use the same core and as such should be able to reach between 275 and 300 quite easily. Obviously the RAM speed is the most important for o/c. Despite what the RAM speed are technically quoted as being able to achieve, reviews and consumers seem to find the following:GF4TI4200 (both 128MB & 64MB) usually use 4.0ns shown to o/c to 550mhz.
GF4TI4400 usually use 3.6ns shown to o/c to 680mhz.
GF4TI4600 usually use 2.8ns shown to o/c to 760mhz.
It would be handy if people could quote what they have found from their cards and the type of RAM that their card uses. It is usually found on the RAM chips and is the last 2 numbers on the second row.EG from a GF2GTS:
SAMSUNG 124
K4062323HA-QC60
UGCV08ED KOREA
Hence this GTS uses 6.0ns RAM from Samsung.
I'll give my 4200-128MB a try at o/c and submit my results ASAP. If people could quote manufacturer, card type and RAM amount/brand/type along with their o/c I think a lot of people would find it both interesting and useful.
