why are the specs different?
i recently bought an evga 9800gtx+
and everywhere online the stock specs are
Core Clock: 675 MHz
Memory Clock: 2200 MHz
Shader Clock: 1690 MHz
HOWEVER when i look at the specs through my computer (evga precision and GPU-z)
the specs are
core = 738
memory = 1100
shader = 1836
why are the specs different (i dont mind the increases =D) but why is the memory speed considerably lower?
1) You probably bought a pre-overclocked card. Take a look and see if your card says Superclocked anywhere on it.
2) The effective memory speed is double the base memory clock. So 2200MHz GDDR3 actually runs at a base speed of 1100MHz. The setting is correct.
It actually is 2200Mhz, the way EVGA and most programs read memory is their base speed. That means whatever they read, say 1100 it actually means you multiply this by 2 to get your true 2200Mhz clock speed. Why they do this i dunno
And as for the core clock.
675mhz = 65nm (9800GTX)
738mhz = 55nm (9800GTX+)
yeah this helps, thanks a lot guys,
btw, the card is not superclocked and it is 65 nm
wierd... anyways i was just concerned about the memory, thanks again
DDR = DOUBLE data rate.
