maybe you're right, i suspected but was not sure...
I would wait the answer from a moderators, they can search the PN in the Sapphire Datasheet...
However, it is strange because my Sapphire Radeon 7500 work at 260Mhz/183Mhz like other Radeon 7500LE instead the Radeon 7500 work at 290Mhz/230Mhz...
Because maybe there are some Radeon 7500LE with DDR memory...
