250MHz/400MHz Ti4200

250MHz core/400MHz memory
Are these the default clock speeds for the MSI Ti4200 DT 128MB 4x? Becuase the default clock settings are always 250 and 400, and i always thought it was suppoesed to be 250/500. Why are all the overclocking utilities telling me i'm clocked at these values?
Or more to the point why is my card's default settings, 250/400????

Ginster,
The original 128MB Ti4200 cards (any Mfg.) used lower speed rated memory chips (to keep costs down), hence, the memory clock speed was anywhere between 400MHz-450MHz.  Some Mfgs. (like Asus) opted for the higher speed rated memory chips on some of their boards and were able to offer the 128MB cards at a higher memory clock speed (and higher cost).
The 64MB cards, however, used faster memory chips - they were cheaper by comparison due to mfg. process and size (8MB each chip for 64MB vs. 16MB each for 128MB) and therefore the memory was clocked at 500MHz or higher (my MSI G4Ti4200 64MB has it's memory at 513MHz by default).
Since then, memory ic prices have dropped, so the newer boards (AGP 8x) are likely fitted with the faster chips - hence, the faster memory clock is applied again.
