Oki, so i bought a tulip visionline dc 486 sx (TC 35 B03 486sx-25) and want to upgrade to a overdrive for better speed 😉

I know i need a ODP and not ODPR version of the overdrive. But after reading on overdrive packages and information document i now wounder if it is possible to buy a dx2odp66 since i have a sx-25 or can i only buy dx2odp50 / dx4odp75 since the intel documentation and "attached" overdrive box pictures says something else?

Ref to cpu upgrade from computer maker ( http://tulipgv.nl/leden/upgrade.htm ) says i can go to dx2 odp and dx4 odp but no information regarding speed

Speed upgrade ref i found regarding why is ay 25 can go to dx2-50 or dx4-75 overdriver:

The 66 and 100 MHz overdrives will happily run at 50/75 MHz in a 25 MHz motherboard and you are right you need the ODP version if you are using it with an upgrade socket, not the ODPR version.

If you want to run the overdrives at 66/100 MHz you need to replace the "tin can" with 50 MHz written on it with a 66 MHz one, this involves soldering if it isn't socketed.
