Overclocking the Core

[Tha General]

Using a BFG Geforce 6200 OC pci Card, / GPU/NV44

Using Rivatuner 2.09, and i notice with alot of cards, its kinda impossible to overclock the core, is reason for this?
It doesn't do it with every card tho, because with the 2400 cards i can oc the core and the memory, but with this 6200 i can oc the memory from 266 to 400-450 or 475, however the core i get the BSOD.

OC the memory is good tho right?

I've never tried to overclock a PCI video card before, perhaps the bus can't handle core ratings that are out of factory spec? I might just be the driver though, have you tried installing different drivers with the same overclock?

Well i am using the 2400HD PCI card now, but i manage to oc the memory just fine with the 6200. With the 2400HD i can overclock card from:

525/400 to 600/450 and it runs at 39c to 43c.

Thanks, peace
