<< I found this somewhere:
8500DV 230/190 5.5ns ram
8500LE 230/230 4ns ram
8500OEM 250/250 3.6 or 4ns ram
8500Retail 275/275 3.6ns ram
Does anybody know the configuration for 8500DV O&M ?? >>
ATi's own Retail R8500 is clocked at 275/275.
Their OEM is clocked at 250/250 with 3.6,3.8, or 4ns DDR SDRAM.
Officially the OEM product IS the Radeon 8500LE, you can find the press release reflecting this at ATi's website.
The majority of third party Radeon boards are clocked at 250/250, but a small handful are clocked at 230/230.
ATi's own All In Wonder R8500DV is clocked at 230/190 in retail or OEM, I've seen it with RAM rated as low as 4.5ns.
I'm not sure of the clockspeed of Hercules AIW R8500DV, though I'd imagine it is the same as that of ATi's.
