The Retail 8500 64MB and the 8500 64MB OEM (BBA) both come with 3.3ns SGRAM DDR clocked at 275mhz. The 128 MB cards use BGA. I'm talking only about BBA cards (Built By ATI).
I'm less sure about the LE cards. I've seen BBA LE's clocked at 250/250, 250/230, and 230/230.
I'm beginning to think only the early model LE's were clocked at 230/230. It seems ATI has settled in with 250/250 for the retail 8500LE and 250/230 for the OEM version.
As far as I know, as with the 8500s, the 64MB LE's have SGRAM DDR and the 128MB LE's have BGA memory. I have no idea of the rated speeds of the memory.
