That's incorrect! That's the Ramdac, which is missing on the late versions of the card, apparently. Not a good indicator in my experience. I have two 8500s that don't have it, one is a Powercolor Evil Master (cute red fan), the other one is an Ati Reference made in china, and both are 275/275. Earlier in this thread I posted a 8500 LE that does have the Ramdac, but that is 250/250. I also have a 8500 Sapphire with red pcb from a 9100 that doesn't have the Ramdac but has 3.6ns memories and is 275/275. Best indication of the clock is the type of ram they have. 4ns = LE, 3.5 or 3.6ns = "pro", 3.3ns = "xt". But like you said, sometimes they did mix bad GPUs with binned memories and vice versa. For example from an italian forum they say they exist 250/275, 250/285, 230/275, 275/285. And even LELE versions, as people called them, like 230/250. But these are easy to spot as they have a low profile PCB.
Edit: also forgot I have a Club3D 9100 that has no Ramdac and is 275/275 (128mb)
