Radeon 64MB DDR Vivo and clock speeds

[NiPNi]

I got my new Radeon card today (64MB DDR Vivo), and I just wondered if there's a way to determine what clock speeds it is running at. At first I thought all 64MB cards ran at 183/183, but then I read something about bulk cards running at 166/166. I tried PowerStrip, and from what I can see there, the actual speeds are 164/164.

So, the question is: what clock speeds IS my card running at? Is there anything on the card itself (serial number, stickers etc...) that can give me an indication? Or can I trust the results from PowerStrip? And, depending on what it is actually running at, how far is it possible to overclock it? Or is it pointless to overclock it? I have seen some tests suggesting that overclocking makes no difference at all on the performance.

Oh, by the way: I love the card, regardless of the clock speeds! Great performance, and awesome image quality!

retail boards should be clocked at 183/183. White box/bulk are 166/166, some use 5.5ns memory so you can crank them to 183mhz ++

Absolutely correct on the clock speeds, but my card came with 6 ns memory but I have oc it to 200. Ran it for a while at 190 also but finally dropped back to 182 while sorting out my new cpu. Time to up it again or maybe just leav it where its at. HTH BTW I had visual artifacts at 210.
